Copying the Virtual Disk
After first preparing the host server(s) as specified in the preceding procedure,
use the following examples to make a virtual disk copy.
The following syntax is the general form of the command:
create virtualDiskCopy source=" sourceName " target=
" targetName " [copyPriority=(highest | high |
medium | low | lowest) targetReadOnlyEnabled=(TRUE
| FALSE)]
NOTE:
Use one or both of the optional parameters as needed to help define your
configuration. It is not necessary to use any optional parameters.
Once the virtual disk copy has started, the source virtual disk will be read only
to all I/O activity. Any write attempts to the source virtual disk will fail until
the operation completes.
Once the virtual disk copy operation is completed register the target virtual
disk with the OS to be used by performing the following steps:
•
Enable write permission on the target virtual disk by either removing the
Virtual Disk Copy Pair or explicitly setting write permission.
–
In Windows, assign a drive letter to the virtual disk.
–
In Linux, mount the virtual disk.
Refer to steps 1 through 4 in the preceding section, "Preparing Host Servers to
Create a Virtual Disk Copy" on page 80. The create virtualDiskCopy
command might look like the following example:
client>smcli 123.45.67.89 -c "create
virtualDiskcopy source=\"Jaba_Hut\" target=
\"Obi_1\" copyPriority=medium
targetreadonlyenabled=true"
The command in this example copies the data from the source virtual disk
named Jaba_Hut to the target virtual disk named Obi_1. Setting the copy
priority to medium provides a compromise between the following storage
array operations:
•
The speed with which the data is copied from the source virtual disk to the
target virtual disk
•
The amount of processing resource required for data transfers to other
virtual disks in the storage array
