Hot Plug Task
The Hot Plug Task provides software function for those devices that support hot-plug or
hot-swap capability. This includes PCI adapters, SCSI devices, and some RAID
devices. This task was previously known as "SCSI Device Identification and Removal"
or "Identify and Remove Resource."
The Hot Plug Task has a restriction when running in Standalone or Online Service
mode; new devices may not be added to the system unless there is already a device
with the same FRU part number installed in the system. This restriction is in place
because the device software package for the new device cannot be installed in
Standalone or Online Service mode.
Depending on the environment and the software packages installed, selecting this task
displays the following three subtasks:
v PCI Hot Plug Manager
v SCSI Hot Swap Manager
v RAID Hot Plug Devices
To run the Hot Plug Task directly from the command line, type the following: diag
-T"identifyRemove"
If you are running the diagnostics in Online Concurrent mode, run the Missing Options
Resolution Procedure immediately after adding, removing or replacing any device. Start
the Missing Options Resolution Procedure is by running the diag -a command.
If the Missing Options Resolution Procedure runs with no menus or prompts, then
device configuration is complete. Otherwise, work through each menu to complete
device configuration.
PCI Hot Plug Manager
The PCI Hot Plug Manager task is a SMIT menu that allows you to identify, add,
remove, or replace PCI adapters that are hot-pluggable. The following functions are
available under this task:
v List PCI Hot Plug Slots
v Add a PCI Hot Plug Adapter
v Replace/Remove a PCI Hot Plug Adapter
v Identify a PCI Hot Plug Slot
v Unconfigure Devices
v Configure Devices
v Install/Configure Devices Added After IPL
The List PCI Hot Plug Slots function lists all PCI hot-plug slots. Empty slots and
populated slots are listed. Populated slot information includes the connected logical
device. The slot name consists of the physical location code and the description of the
physical characteristics for the slot.
The Add a PCI Hot Plug Adapter function is used to prepare a slot for the addition of
a new adapter. The function lists all the empty slots that support hot plug. When a slot
