Pci Hot Plug Manager - IBM pSeries 690 User Manual

PCI Hot Plug Manager

Attention: The Linux operating system does not support some hot-pluggable procedures. Also, Linux
does not support hot-plugging any hot-pluggable PCI adapters or devices. A system with Linux installed on
one or more partitions must be shut down and powered off before replacing any PCI adapter or device
assigned to a Linux partition. Please follow the non-hot-pluggable adapter or device procedures when
replacing a PCI adapter or device in any partition with Linux installed.
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 is selected, the visual indicator for the
slot blinks at the Identify rate. 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 new adapter can be
plugged in.
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.
