7. To prepare to remove a PCIe adapter by using the AIX operating system, complete the following
steps:
a) You must take the PCIe adapter offline before you remove and replace a PCIe adapter when the
system power is turned on (hot-plugging). Before you take an adapter offline, the devices that are
attached to the adapter must be taken offline as well. This action must be done by a system
administrator. Taking the PCIe adapter offline prevents a service representative or user from
causing an unexpected outage for other users of the system.
b) Before hot-plugging adapters or storage devices, ensure that the file systems on those devices are
unmounted.
c) Ensure that any processes or applications that might use the adapter are stopped.
d) To identify the failed PCIe adapter, complete the steps in this procedure on the console:
1) Log in as root user.
2) At the command line, type diag and then press Enter.
3) From the Function Selection menu, select Task Selection > Hot Plug Task > PCI Hot Plug
Manager > Unconfigure a Device.
4) Press F4 (or Esc +4) to display the Device Names menu.
5) Select the adapter that you are removing in the Device Names menu.
6) Use the Tab key to answer No to Keep Definition. Use the Tab key again to answer Yes to
Unconfigure Child Devices, and then press Enter. Press Enter to confirm the operation. The
OK message next to the Command field confirms a successful unconfiguration.
7) Press F3 (or Esc +3) twice to return to the Hot Plug Manager menu.
8) Select replace/remove PCI Hot Plug adapter and then select the slot that contains the
adapter to be removed from the system.
9) Select remove. The amber LED for the PCI adapter flashes for the slot that is identified.
10) Physically verify that the slot you identified is where you want to remove the adapter.
Notes:
• Use the blue identify LED on the enclosure to locate the system. Ensure that the serial
number of the system matches the serial number to be serviced.
