A multi-tiered storage pool is used to enable automatic migration of extents between disk tiers by using the IBM Storwize V5000 Gen2 IBM Easy Tier function, as described in Chapter 9, “Advanced features for storage efficiency” on page 437.
Page 47 A sequential volume is a volume in which the extents are allocated one after the other from one MDisk to the next MDisk, as shown in Figure 1-11. Figure 1-11 Sequential volume Image mode Chapter 1. Overview of the IBM Storwize V5000 Gen2 system...
Page 48: Iscsi
IBM Storwize V5000 Gen2. The iSCSI function is a software function that is provided by the IBM Storwize V5000 Gen2 code, not hardware. In the simplest terms, iSCSI allows the transport of SCSI commands and data over an Internet Protocol network that is based on IP routers and Ethernet switches.
Page 49: Serial-Attached Scsi
Fibre Channel (FC) is the traditional method that is used for data center storage connectivity. The IBM Storwize V5000 Gen2 supports FC connectivity at speeds of 4, 8, and 16 Gbps. Fibre Channel Protocol is used to encapsulate SCSI commands over the FC network. Each device in the network has a unique 64-bit worldwide port name (WWPN).
Page 50: Thin Provisioning
When a host system issues a write to a mirrored volume, IBM Storwize V5000 Gen2 writes the data to both copies. When a host system issues a read to a mirrored volume, IBM Storwize V5000 Gen2 requests it from the primary copy.
Page 51: Real-Time Compression
The Storwize V5030 model can create compressed volumes, allowing more data to be stored in the same physical space. IBM Real-time Compression™ (RtC) can be used for primary active volumes and with mirroring and replication (FlashCopy/Remote Copy). RtC is available on the Storwize V5030 model only.
Page 52: Easy Tier
IBM Easy Tier provides a mechanism to seamlessly migrate extents to the most appropriate tier within the IBM Storwize V5000 Gen2 solution. This migration can be to different tiers of internal drives within IBM Storwize V5000 Gen2 or to external storage systems that are virtualized by IBM Storwize V5000 Gen2, for example, an IBM FlashSystem 900.
Page 53: Remote Copy
Remote Copy can be implemented in one of two modes, synchronous or asynchronous. With the IBM Storwize V5000 Gen2, Metro Mirror and Global Mirror are the IBM branded terms for the functions that are synchronous Remote Copy and asynchronous Remote Copy.
Page 54: External Virtualization
IP replication can be configured to use any of the available 1 GbE or 10 GbE Ethernet ports (apart from the technician port) on the IBM Storwize V5000 Gen2. See Table 1-10 on page 18 for port configuration options.
Page 55: Problem Management And Support
The syslog protocol is a standard protocol for forwarding log messages from a sender to a receiver on an IP network. The IP network can be IPv4 or IPv6. IBM Storwize V5000 Gen2 can send syslog messages that notify personnel about an event. IBM Storwize V5000 Gen2 can transmit syslog messages in expanded or concise format.
Page 56: Call Home Email
When configured, this function alerts IBM service personnel about hardware failures and potentially serious configuration or environmental issues. You can use the Call Home function if you have a maintenance contract with IBM or if the IBM Storwize V5000 Gen2 is within the warranty period.

Page 61 Storwize V5030 The Storwize V5030 supports up to 20 expansion enclosures per I/O group in two SAS chains of 10. Up to 40 expansion enclosures can be supported in a two I/O group configuration. To install the cables, complete the following steps: 1.
Page 62: San Configuration Planning
Storwize systems that are visible on the SAN fabric. The Storwize V5010 and V5020 models support a single I/O group only and can migrate from external storage controllers only. The Storwize V5030 supports up to two I/O groups that form a cluster over the FC fabric.
Page 63 WWPNs (two from each node canister) on each of the two fabrics. If an external storage system is to be virtualized, create a zone in each fabric with the IBM Storwize V5000 Gen2 worldwide port names (WWPNs) (two from each node canister) with up to a maximum of eight WWPNs from the external storage system.
Page 64: Fc Direct-Attach Planning
The advised configuration for direct attachment is at least one Fibre Channel cable from the host that is connected to each node of the IBM Storwize V5000 Gen2 to provide redundancy if one of the nodes goes offline, as shown in Figure 2-5 on page 43.
Page 65 V5000 Gen2 I/O groups (the Storwize V5030), we suggest that at least one Fibre Channel cable is used from the host to each of the node canisters of the IBM Storwize V5000 Gen2, as shown in Figure 2-6. This suggestion also applies to a cluster where one I/O group is a Storwize V5000 Gen1 and the other I/O group is a Storwize V5030.
Page 66: Sas Direct-Attach Planning
Verify direct-attach interoperability with the IBM Storwize V5000 Gen2 and the supported server operating systems by following the requirements that are provided at this website: https://ibm.biz/BdrDsy 2.4 SAS direct-attach planning The Storwize V5000 Gen2 allows SAS host attachment by using an optional SAS card that must be installed in both node canisters.
Page 67: Lan Configuration Planning
2.5 LAN configuration planning Two Ethernet ports per node canister are available for connection to the LAN on an IBM Storwize V5000 Gen2 system. Use Ethernet port 1 to access the management graphical user interface (GUI), the service assistant GUI for the node canister, and iSCSI host attachment.
Page 68: Management Ip Address Considerations
In normal operation, the service IP addresses are not needed. However, if a node canister problem occurs, it might be necessary for service personnel to log on to the node to perform service actions. Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 69: Host Configuration Planning
SAN fabric or the fabric fails, the host loses access to its volumes. Even with a single connection to the SAN, the host has multiple paths to the IBM Storwize V5000 Gen2 volumes because that single connection must be zoned with at least one Fibre Channel port per node.
Page 70: Miscellaneous Configuration Planning
 Document the LAN NTP server IP address that is used for the synchronization of devices.  To send alerts to storage administrators and to set up Call Home to IBM for service and support, you need the following information: ...
Page 71: System Management
The only other role that is available is the service role, which is used if you create a user ID for the IBM service support representative (SSR). With this user role, IBM service personnel can view anything on the system (as with the Monitor role) and perform service-related commands, such as adding a node back to the system after it is serviced or including disks that were excluded.

Page 250 Starting with IBM Spectrum Virtualize V7.7.0, the IBM Spectrum Virtualize system can be enabled into NPIV mode. When NPIV mode is enabled on the IBM Spectrum Virtualize system, ports do not come up until they are ready to service I/O, which improves host behavior around node unpends.
Page 251 When NPIV is enabled on IBM Spectrum Virtualize system nodes, each physical WWPN reports up to three virtual WWPNs, as shown in Table 5-1. Table 5-1 Spectrum Virtualize NPIV Ports’s NPIV port Port description Primary NPIV Port This is the WWPN that communicates with backend storage, and might be used for node to node traffic.

Page 303 In IBM Spectrum Virtualize, by default, no I/O throttling rate is set. However, I/O throttling can be set at any of the following levels: Host Host clusters Volume MDisk group When I/O throttling is set, the I/O rate is limited by queuing I/Os if it exceeds preset limits. I/O throttling does not guarantee minimum performance.

A seeding host used for creating a Host Cluster cannot have a host throttle defined for it. 5.7 Proactive Host Failover During planned maintenance procedures of IBM Storwize V5000 Gen2, such as firmware upgrade or node canister replacement, at times the host multipathing driver may experience issues recovering paths to volumes.
Page 308 The following points are worth noting in regards to Proactive Host Failover: When an IBM Spectrum Virtualize system knows a node canister is about to go down, it raises unit attentions to try to trigger host path failovers to surviving node canisters.
Page 309: Chapter 6. Volume Configuration
A volume is a logical disk provisioned out of a storage pool and is recognized by a host with a unique identifier (UID) field and a parameter list. The first part of this chapter provides a brief overview of IBM Spectrum Virtualize volumes, the classes of volumes available, and the topologies that they are associated with. It also provides an overview of advanced customization available.
Page 310: Introduction To Volumes
6.1 Introduction to volumes A volume is a logical disk that the system presents to attached hosts. For an IBM Spectrum Virtualize system, the volume presented is from a virtual disk (VDisk). A volume is a discrete area of usable storage that has been virtualized, using IBM Spectrum Virtualize code, from storage area network (SAN) storage that is managed by the IBM Spectrum Virtualize cluster.
Page 311: Image Mode Volumes
Image mode volumes are used to migrate LUNs that were previously mapped directly to host servers over to the control of the IBM Spectrum Virtualize system. Image mode provides a one-to-one mapping between the logical block addresses (LBAs) between a volume and an MDisk.
Page 312: Managed Mode Volumes
MDisk. It cannot be a quorum disk and it does not have any metadata extents that are assigned to it from the IBM Spectrum Virtualize system. Managed or image mode MDisks are always members of a storage pool.
Page 313: Cache Mode For Volumes
Figure 6-3 shows this mapping. It also shows a volume that consists of several extents that are shown as V0 - V7. Each of these extents is mapped to an extent on one of the MDisks: A, B, or C. The mapping table stores the details of this indirection. Several of the MDisk extents are unused.
Page 314: Mirrored Volumes
Having cache-disabled volumes makes it possible to use the native copy services in the underlying RAID array controller for MDisks (LUNs) that are used as the IBM Spectrum Virtualize image mode volumes. Using IBM Spectrum Virtualize Copy Services rather than the underlying disk controller copy services gives better results.
Page 315 Figure 6-4 provides an overview of volume mirroring. Figure 6-4 Volume mirroring overview A second copy can be added to a volume with a single copy or removed from a volume with two copies. Checks prevent the accidental removal of the only remaining copy of a volume. A newly created, unformatted volume with two copies initially has the two copies in an out-of-synchronization state.
Page 316 Write I/O operations data flow with a mirrored volume For write I/O operations to a mirrored volume, the IBM Spectrum Virtualize preferred node definition, with the multipathing driver on the host, is used to determine the preferred path.
Page 317: Thin-Provisioned Volumes
The is the capacity of the volume that is reported to all other IBM Spectrum Virtualize components (for example, FlashCopy, cache, and remote copy), and to the host servers. real capacity is used to store the user data and the metadata for the thin-provisioned volume.
Page 318 The metadata storage used is never greater than 0.1% of the user data. The resource usage is independent of the virtual capacity of the volume. If you are using the thin-provisioned volume directly with a host system, use a small grain size. Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 319: Compressed Volumes
One license is required for each control or expansion enclosure and each enclosure in any external storage systems that use virtualization.To use the compression function, you must obtain the IBM Real-time Compression license. Note: For IBM Storwize V5000 Gen2, only Storwize V5030 and Storwize V5030F models support compression. Chapter 6. Volume configuration...

Page 328: Creating Mirrored Volumes Using Volume Creation
6.3.2 Creating Mirrored volumes using Volume Creation IBM Spectrum Virtualize offers the capability to mirror volumes, which means a single volume, presented to a host, can have two physical copies. Each volume copy can belong to a different pool, and each copy has the same virtual capacity as the volume. When a server writes to a mirrored volume, the system writes the data to both copies.
Page 329 Generally, keep mirrored volumes on a separate set of physical disks (Pools). Leave the I/O group option at its default setting of Automatic (see Figure 6-17). Figure 6-17 Mirrored Volume creation 2. Click Create (or Create and Map to Host) Chapter 6.
Page 330 Volume Creation with Capacity Saving options The Volume Creation operation also provides, using the Capacity Savings parameter, the ability to alter the provisioning of a Basic or Mirrored volume into Thin-provisioned or Compressed.

100 GiB, but virtual capacity of 1 tebibyte (TiB). The actual space used by the volume on IBM Storwize V5000 Gen2 is 100 GiB, but hosts see a 1 TiB volume. A directory maps the virtual address space to the real address space. The directory and the user data share the real capacity.
Page 490 The fully allocated to thin-provisioned migration procedure uses a zero-detection algorithm, so that grains that contain all zeros do not cause any real capacity to be used. Usually, IBM Storwize V5000 Gen2 is supposed to detect zeros on the volume, so you must use software on the host side to write zeros to all unused space on the disk or file system.

Page 493: Limitations Of Virtual Capacity
File system problems can be moderated by tools, such as defrag, or by managing storage by using host Logical Volume Managers (LVMs). The thin-provisioned volume also depends on how applications use the file system. For example, some applications delete log files only when the file system is nearly full.
Page 494: Real-Time Compression Software
No changes to the existing environment are required IBM Real-time Compression is part of the storage system. It was designed to be implemented without changes to applications, hosts, networks, fabrics, or external storage systems. The solution is not apparent to hosts, so users and applications continue to work non-disruptively.
Page 495: Real-Time Compression Concepts
The primary intellectual property behind this is the RACE engine. At a high level, the IBM RACE component compresses data that is written into the storage system dynamically. This compression occurs transparently, so Fibre Channel and iSCSI connected hosts are not aware of the compression.
Page 496: Random Access Compression Engine
Capacity is saved when the data is written by the host because the host writes are smaller when they are written to the storage pool. IBM Real-time Compression is a self-tuning solution. It is adapting to the workload that runs on the system at any particular moment.
Page 497 Figure 9-26 shows compression that uses a sliding window, where the first two repetitions of the string “ABCD” fall within the same compression window, and can therefore be compressed by using the same dictionary. The third repetition of the string falls outside of this window, and therefore cannot be compressed by using the same compression dictionary as the first two repetitions, reducing the overall achieved compression ratio.
Page 498 Although this approach is an evolution from compression utilities, it is limited to low-performance use cases. This limitation is mainly because it does not provide real random access to the data. Figure 9-27 Traditional data compression in storage systems Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 499 Random Access Compression Engine The IBM patented RACE implements an inverted approach when compared to traditional approaches to compression. RACE uses variable-size chunks for the input, and produces fixed-size chunks for the output. This method enables an efficient and consistent way to index the compressed data because it is stored in fixed-size containers (Figure 9-28).
Page 500 This type of data compression is called because the data repetition detection is based on the time the data was written into the same compressed block. Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 501: Random Access Compression Engine In Ibm Spectrum Virtualize Stack
RACE technology is implemented into the Storwize thin provisioning layer and is an organic part of the stack. Compression is transparently integrated with existing system management design. All of the IBM Storwize V5000 Gen2 advanced features are supported on compressed volumes. You can create, delete, migrate, map (assign), and unmap (unassign) a compressed volume as though it were a fully allocated volume.
Page 502: Data Write Flow
9.4.6 Data read flow When a host sends a read request to the IBM Storwize V5000 Gen2 for compressed data, it is forwarded directly to the Real-time Compression component: If the Real-time Compression component contains the requested data, IBM Spectrum Virtualize cache replies to the host with the requested data without having to read the data from the lower-level cache or disk.
Page 503 It enables them to see a tremendous return on their IBM Storwize V5000 Gen2 investment. On initial purchase of a IBM Storwize V5000 Gen2 with Real-time Compression, customers can defer their purchase of new storage. As new storage needs to be acquired, IT purchases a lower amount of the required storage before compression.
Page 504: Configuring Compressed Volumes
This setting can affect your system performance if you do not plan accordingly in advance. 9.4.8 Configuring compressed volumes To use compression on the IBM Storwize V5000 Gen2, licensing is required. With the IBM Storwize V5000 Gen2, Real-time Compression is licensed by enclosure. Every enclosure that works with compression needs to be licensed.

V5000 Gen2 storage system, including FlashCopy, Remote Copy and HyperSwap. Copy services functions are useful for making data copies for backup, application test, recovery, and so on. The IBM Storwize V5000 Gen2 system makes it easy to apply these functions to your environment through its intuitive graphical user interface (GUI).
Page 508: Ibm Flashcopy
10.1 IBM FlashCopy By using the IBM FlashCopy function of the IBM Spectrum Virtualize, you can perform a point-in-time copy of one or more volumes. This section describes the inner workings of FlashCopy and provides details about its configuration and use.
Page 509: Restore With Flashcopy
After the FlashCopy is performed, the resulting image of the data can be backed up to tape, as though it were the source system. After the copy to tape is complete, the image data is redundant and the target volumes can be discarded. For time-limited applications, such as these examples, “no copy”...

The target volume can be updated independently of the source volume. Bitmaps that are governing I/O redirection (I/O indirection layer) are maintained in both node canisters of the IBM Storwize I/O Group to prevent a single point of failure. FlashCopy mapping and Consistency Groups can be automatically withdrawn after the completion of the background copy.

The source and target volumes must belong to the same IBM Storwize V5000 system Gen2 system, but they do not have to be in the same I/O Group or storage pool. FlashCopy associates a source volume to a target volume through FlashCopy mapping.
Page 515: Multiple Target Flashcopy
Figure 10-3 FlashCopy mapping 10.3.2 Multiple Target FlashCopy The IBM Storwize V5000 Gen2 system supports up to 256 target volumes from a single source volume. Each copy is managed by a unique mapping. Figure 10-4 shows the Multiple Target FlashCopy implementation.

Page 519: Grains And The Flashcopy Bitmap
10.3.5 Grains and the FlashCopy bitmap When data is copied between volumes, it is copied in units of address space that are known grains. Grains are units of data that are grouped to optimize the use of the bitmap that tracks changes to the data between the source and target volume.
Page 520: Interaction And Dependency Between Multiple Target Flashcopy Mappings
Figure 10-7 shows a set of four FlashCopy mappings that share a common source. The FlashCopy mappings target volumes Target 0, Target 1, Target 2, and Target 3.

Page 521 In Figure 10-7 on page 498, Target 0 is not dependent on a source because it completed copying. Target 0 has two dependent mappings (Target 1 and Target 2). Target 1 depends on Target 0. It remains dependent until all of Target 1 is copied. Target 2 depends on it because Target 2 is 20% copy complete.
Page 522: Summary Of The Flashcopy Indirection Layer Algorithm
Upper cache serves mostly as write cache and hides the write latency from the hosts and application. Lower cache is a read/write cache and optimizes I/O to and from disks. Figure 10-8 shows the new IBM Spectrum Virtualize cache architecture.
Page 523: Flashcopy And Image Mode Volumes
Figure 10-9 Logical placement of the FlashCopy indirection layer Introduction of the two-level cache provides additional performance improvements to the FlashCopy mechanism. Because now the FlashCopy layer is above lower cache in the IBM Spectrum Virtualize software stack, it can benefit from read prefetching and coalescing writes to backend storage.

Page 531 Storwize V5000 copies per second, assuming that the bandwidth to the managed disks (MDisks) can accommodate this rate. If the IBM Storwize V5000 Gen2 system cannot achieve these copy rates because of insufficient width from the nodes to the MDisks, the background copy I/O contends for resources on an equal basis with the I/O that is arriving from the hosts.
Page 532: Event Handling
In a fully functioning system, all of the nodes have a software representation of every volume in the system within their application hierarchy. Because the storage area network (SAN) that links IBM Storwize V5000 Gen2 system node canisters to each other and to the MDisks is made up of many independent links, it is possible for a subset of the nodes to be temporarily isolated from several of the MDisks.
Page 533: Asynchronous Notifications
Path Offline for the source volume If a FlashCopy mapping is in the copying state and the source volume goes path offline, this path offline state is propagated to all target volumes up to, but not including, the target volume for the newest mapping that is 100% copied but remains in the copying state.
Page 534: Flashcopy Presets
I/O Group must be the same. 10.3.18 FlashCopy presets The IBM Spectrum Virtualize GUI interface provides three FlashCopy presets (Snapshot, Clone, and Backup) to simplify the more common FlashCopy operations. Although these presets meet most FlashCopy requirements, they do not support all possible FlashCopy options.
Page 535 Use case The user wants to produce a copy of a volume without affecting the availability of the volume. The user does not anticipate many changes to be made to the source or target volume; a significant proportion of the volumes remains unchanged. By ensuring that only changes require a copy of data to be made, the total amount of disk space that is required for the copy is reduced.
Page 536: Managing Flashcopy By Using The Gui
However, in enterprise data centers with many host mappings, we suggest that you use the CLI to run your FlashCopy commands. This section describes the tasks that you can perform at a FlashCopy level using the IBM Spectrum Virtualize GUI.
Page 537: Creating A Flashcopy Mapping
In its basic mode, the IBM FlashCopy function copies the contents of a source volume to a target volume. Any data that existed on the target volume is lost, and that data is replaced by the copied data. From the Copy Services option on the main panel, use the Consistency Groups option, as Consistency Group shown in Figure 10-11.

Export to Image mode. By using this option, you can move storage from managed mode to image mode, which is useful if you are using the IBM Storwize as a migration device. For example, vendor A’s product cannot communicate with vendor B’s product, but you must migrate existing data from vendor A to vendor B.

When a MM/GM relationship is stopped in the ConsistentSynchronized state, the MM/GM relationship enters the Idling state when you specify the -access option, which enables write I/O on the auxiliary volume.
Page 602 Relationships that are configured between volumes in the same IBM Storwize V5000 Gen2 system (intracluster) are never described as being in a disconnected state.
Page 603 When you are deciding how to use Consistency Groups, the administrator must consider the scope of an application’s data and consider all of the interdependent systems that communicate and exchange information. If two programs or systems communicate and store details as a result of the information exchanged, either of the following actions might occur: All of the data that is accessed by the group of systems must be placed into a single Consistency Group.

Page 605 ConsistentSynchronized ConsistentSynchronized is a connected state. In this state, the master volume is accessible for read and write I/O, and the auxiliary volume is accessible for read-only I/O. Writes that are sent to the master volume are also sent to the auxiliary volume. Either successful completion must be received for both writes, the write must be failed to the host, or a state must transition out of the ConsistentSynchronized state before a write is completed to the host.

Page 650: Hyperswap
If your investigations fail to resolve your remote copy problems, contact your IBM Support representative for a more complete analysis.
Page 651: Introduction To Hyperswap Volumes
The HyperSwap function uses a hyperswap topology by spreading the control enclosure of the system across two sites, with storage at a third site that acts as a tie-breaking quorum device: The HyperSwap topology requires at least one control enclosure in each main data site. Therefore, to get a volume that is resiliently stored on both sites, one control enclosure with the necessary storage capacity is required.
Page 652 However, only one app is active at a time. The other apps are available if the active quorum device app fails. For more information about quorum devices, see the Storwize V5000 IBM Knowledge Center: https://ibm.biz/BdjaUk Because HyperSwap is running as a single cluster that is distributed across two main data centers, one Storwize V5000 control enclosure is required in each site.
Page 653 A site attribute must be set for any host, Storwize V5000 storage system, and external virtualized storage system. The host uses the local I/O group (same site attribute) for data access, as shown in Figure 10-157. The continuous blue line shows the host default access path to the volume at the same site. The dotted blue line shows the non-preferred access path that is used if the preferred access path is not available.
Page 654 The host reads and writes data to the local I/O group within the same site. The HyperSwap system sends the data to the remote site by using internal Metro Mirror, as shown in Figure 10-158. Figure 10-158 Data flow for a single volume Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 655 If a host accesses the volume on the Metro Mirror target site, all read and write requests can be forwarded to the I/O group that acts as the Metro Mirror source volume, as shown in Figure 10-159. All host-related traffic must be handled from the remote I/O group, which increases the long-distance data traffic.
Page 656 Applications with an equal workload pattern to the same volume by using both I/O groups (Oracle Real Application Clusters (RAC) and VMware vMotion) are not optimal for local HyperSwap. Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 657: Failure Scenarios
10.12.2 Failure scenarios If one node fails, the other node in the same I/O group takes over the responsibility for all volumes that are owned by the affected I/O group, as shown in Figure 10-161. The system can deactivate the write cache, which might influence the overall performance. The multipath driver can switch the active paths to the named node.
Page 658 Figure 10-162. The remote I/O group handles all volume-related traffic, but HyperSwap cannot keep both copies in sync anymore because of an inactive I/O group. Figure 10-162 I/O group failure Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 659 As soon as the failed I/O group is back, the system can automatically resynchronize both copies in the background. Before the resynchronization, the Storwize V5000 can perform a FlashCopy on HyperSwap source and target volumes, as shown in Figure 10-163. Each change volume requires two FlashCopy relationships, one relationship in each direction.

Page 663: Chapter 11. External Storage Virtualization
IBM Storwize V5030. Virtualizing external storage means the creation of logical units with no data on them and the addition of these logical units to storage pools under the IBM Storwize V5030 control. In this way, the external storage can benefit from the IBM Storwize V5030 features, such as Easy Tier and Copy Services.
Page 664: Planning For External Storage Virtualization
The external storage systems that are incorporated into the IBM Storwize V5030 environment can be new systems or existing systems. Any data on the existing storage systems can be easily migrated to an environment that is managed by the IBM Storwize V5030, as described in Chapter 7, “Storage migration” on page 349.

Page 671: Importing Image Mode Volumes
LUNs can continue to access data, but the hosts must be rezoned and mapped to the Storwize V5030 to use these external storage system LUNs after they are presented through the IBM Storwize V5030. Figure 11-9 shows how to import an unmanaged MDisk: 1.
Page 672 – You can choose between importing the volume to a temporary pool as an volume , which the IBM Storwize V5030 can create and name for you, or migrating the volume to an existing pool. An image mode volume has a direct block-for-block translation from the imported MDisk and the external LUN.
Page 673 If an existing storage pool is chosen, the Storwize V5030 can perform a migration task. The external LUN can be imported into a temporary migration pool and a migration task can run in the background to copy data to MDisks that are in the target storage pool. At the end of the migration, the external LUN and its associated MDisk can be in the temporary pool and show as managed, but they can be removed from the Storwize V5030.

Page 765: Chapter 13. Encryption
Encryption protects against the potential exposure of sensitive user data that is stored on discarded, lost, or stolen storage devices. IBM Storwize V5020, IBM Storwize V5030F and IBM Storwize V5030 support optional encryption of data at-rest. IBM Storwize V5010 does not support encryption.
Page 766: Planning For Encryption
Secret keys are used to encode the data according to well-known algorithms. Encryption of data at-rest as implemented in IBM Spectrum Virtualize is defined by the following characteristics: Data at-rest means that the data is encrypted on the end device (drives).
Page 767 At least three USB flash drives are required if you plan not to use a key management server. They are available as a feature code from IBM (see the note on 761). You must activate the license that you purchased.
Page 768 To enable encryption of both data copies, the Storwize V5000 Gen1 must be replaced by an encryption capable IBM Spectrum Virtualize system, as shown in Figure 13-2. After such replacement both copies of data are encrypted, but the Remote Copy communication between both sites remains unencrypted.
Page 769: Encryption Methods
13.2.1 Encryption methods There are two ways to perform encryption on devices running IBM Spectrum Virtualize: hardware encryption and software encryption. Both methods of encryption protect against the potential exposure of sensitive user data that are stored on discarded, lost, or stolen media.

Page 795 For more information about completing these tasks, see SKLM at IBM Knowledge Center: https://www.ibm.com/support/knowledgecenter/SSWPVP Access to the key server storing the correct master access key is required to enable encryption for the cluster after a system restart such as a system-wide reboot or power loss.
Page 796 IP address of the key servers. Note that the first key server specified must be the primary SKLM key server. Note: The supported versions of IBM Security Key Lifecycle Manager (up to V2.7, which was the latest code version when this book was written) differentiate between primary and secondary key server role.
Page 797 5. The next page in the wizard is a reminder that SPECTRUM_VIRT device group dedicated for IBM Spectrum Virtualize systems must exist on the SKLM key servers. Make sure that this device group exists and click Next to continue, as shown in Figure 13-43.

Page 801 11.The next screen presents you with the summary of the configuration that will be implemented on the system, as shown in Figure 13-49. Click Finish to create the key server object and finalize the encryption enablement. Figure 13-49 Encryption configuration summary in two providers scenario 12.If there are no errors while creating the key server object, the system displays a screen that confirms that the encryption is now enabled on the system, and that both encryption key providers are enabled (see Figure 13-50).
Page 802: Configuring Additional Providers
When the system is configured with a single encryption key provider, it is possible to add a second provider. Note: If you set up encryption of your storage system when it was running IBM Spectrum Virtualize code version earlier than V7.8.0, then when you upgrade to code version V8.1 you have to rekey the master encryption key before you can enable second encryption provider.
Page 803 2. Subsequently, follow the steps required to configure the key server provider, as described in 13.4.3, “Enabling encryption using key servers” on page 765. One difference to the process described in that section is that the wizard will give you an option to migrate from the USB flash drive provider to key server provider.
Page 804: Adding Usb Flash Drives As A Second Provider
If the storage system is already configured with an SKLM encryption key provider, it is possible to configure USB flash drives as a second provider. To enable USB flash drives as a second provider follow these steps: Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 805 1. Go to Settings → Security → Encryption, expand the USB Flash Drives section and click Configure, as shown in Figure 13-57. Note that to enable USB flash drives as a second provider, the system has to be able to access key servers with the current master access key.
Page 806: Migrating Between Providers
Figure 13-59 Encryption enabled with two key providers available 13.6 Migrating between providers IBM Spectrum Virtualize V8.1 introduced support for simultaneous use of both USB flash drives and a key server as encryption key providers. The system also allows migration from configuration using only USB flash drive provider to key servers provider and vice versa.
Page 807: Migration From Encryption Key Server To Usb Flash Drive Provider
13.6.2 Migration from encryption key server to USB flash drive provider Migration in the other direction, that is to say from using encryption key servers provider to USB flash drives provider, is not possible using only the GUI. To perform the migration, add USB flash drives as a second provider. You can do this by following steps described in 13.5.2, “Adding USB flash drives as a second provider”...
Page 808: Encrypted Pools
It is possible to create unencrypted arrays from CLI by manually overriding the default encryption setting. Notes: Encryption support for Distributed RAID is available in IBM Spectrum Virtualize code V7.7 and later. You must decide whether to encrypt or not encrypt an object when it is created. You cannot change this setting at a later time.
Page 809 You can customize Pools view in the management GUI to show pool encryption status. Click Pools → and again Pools, and then click the Actions → Customize Columns → Encryption, as shown in Figure 13-62. Figure 13-62 Pool encryption state If you create an unencrypted pool, but you add only encrypted arrays or self-encrypting MDisks to the pool, then the pool will be reported as encrypted, because all extents in the pool are encrypted.
Page 810: Encrypted Child Pools
If you modify Pools view as described earlier in this section, you will see the encryption status of child pools, as shown in Figure 13-65. The example shows an encrypted child pool with non-encrypted parent pool. Figure 13-65 Child pool encryption state Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 811: Encrypted Arrays
13.8.3 Encrypted arrays See Chapter 4, “Storage pools” on page 143 for instructions on how to add internal storage to a pool. After encryption is enabled, all newly built arrays are hardware encrypted by default. The graphical user interface (GUI) supports only this default option. Note: To create an unencrypted array when encryption is enabled use the command-line interface (CLI) to run the mkarray -encrypt no command.
Page 812: Encrypted Mdisks
Another failure mode is to misconfigure an external MDisk as self-encrypting, while in reality it’s not self-encrypting. In that case, the data written to this MDisk would not be encrypted by IBM SAN Volume Controller, because IBM SAN Volume Controller would be convinced that MDisk will encrypt the data by itself.
Page 813 Assign Storage view, as shown in Figure 13-69. Figure 13-69 Externally encrypted MDisk IBM Spectrum Virtualize products can detect that an MDisk is self-encrypting by using the SCSI Inquiry page C2. MDisks provided by other IBM Spectrum Virtualize products will report this page correctly.
Page 814: Encrypted Volumes
Note that a volume is reported as encrypted only if all the volume copies are encrypted, as shown in Figure 13-72. Figure 13-72 Volume encryption status depending on volume copies encryption Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 815: Restrictions
When creating volumes make sure to select encrypted pools to create encrypted volumes, as shown in Figure 13-73. Figure 13-73 Create an encrypted volume by selecting an encrypted pool You cannot change an existing unencrypted volume to an encrypted version of itself dynamically.

Page 820: Migrating Between Key Providers
It is also possible to migrate from key server provider to USB provider or, if you have both providers enabled, to disable either of them. However, these operations are possible only via the CLI. Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1...
Page 821: Disabling Encryption
13.11 Disabling encryption You are prevented from disabling encryption if there are any encrypted objects defined apart from self-encrypting MDisks. You can disable encryption in the same way whether you use USB flash drives, key server or both providers. To disable encryption, follow these steps: 1.
