IBM 6C4 - Manual (Page 152)

The Replace/Remove a PCI Hot Plug Adapter function is used to prepare a slot for
adapter exchange. The function lists all the PCI slots that support hot plug and are
occupied. The list includes the slot’s physical location code and the device name of the
resource installed in the slot. The adapter must be in the Defined state before it can be
prepared for hot-plug removal. When a slot is selected, the visual indicator for the slot
is set to the Identify state. After the slot location is confirmed, the visual indicator for the
specified PCI slot is set to the Action state. This means the power for the PCI slot is off,
and the adapter can be removed or replaced.
The Identify a PCI Hot Plug Slot function is used to help identify the location of a PCI
hot-plug adapter. The function lists all the PCI slots that are occupied or empty and
support hot plug. When a slot is selected for identification, the visual indicator for the
slot is set to the Identify state.
The Unconfigure Devices function attempts to put the selected device, in the PCI
hot-plug slot, into the Defined state. This action must be done before any attempted
hot-plug function. If the unconfigure function fails, it is possible that the device is still in
use by another application. In this case, the customer or system administrator must be
notified to quiesce the device.
The Configure Devices function allows a newly added adapter to be configured into
the system for use. This function should also be done when a new adapter is added to
the system.
The Install/Configure Devices Added After IPL function attempts to install the
necessary software packages for any newly added devices. The software installation
media or packages are required for this function.
Standalone Diagnostics has restrictions on using the PCI Hot-Plug Manager. For
example:
v Adapters that are replaced must be exactly the same FRU part number as the
adapter being replaced.
v New adapters cannot be added unless a device of the same FRU part number
already exists in the system, because the configuration information for the new
adapter is not known after the Standalone Diagnostics are booted.
v The following functions are not available from the Standalone Diagnostics and will
not display in the list:
– Add a PCI Hot Plug Adapter
– Configure Devices
– Install/Configure Devices Added After IPL
You can run this task directly from the command line by typing the following command:
diag -d device -T"identifyRemove"
However, note that some devices support both the PCI Hot-Plug task and the RAID
Hot-Plug Devices task. If this is the case for the
device specified, then the Hot Plug
Task displays instead of the PCI Hot Plug Manager menu.
