a) Before you hot-plug an adapter, ensure that the server or partition is at the correct level of the
Linux operating system.
b) Verify that the Linux, hot-plug PCI tools are installed.
For instructions, see PCIe hot-plug manager menu (www.ibm.com/support/knowledgecenter/
POWER9/p9hak/pxhak_linuxhotplugverify.htm).
c) Ensure that you have the POWER
enable system serviceability, as well to improve system management. If you are using a Linux on
POWER distribution with Linux kernel version 2.6 or later, you can install the Service Aids that
gives you access to more capabilities, which can help you diagnose problems on your system. This
software is available at the Service and productivity tools for Linux on POWER website (http://
www14.software.ibm.com/webapp/set2/sas/f/lopdiags/home.html).
d) 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.
e) Before hot-plugging adapters or storage devices, ensure that the file systems on those devices are
unmounted.
f) Ensure that any processes or applications that might use the adapter are stopped.
g) Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions,
see Identifying a part (www.ibm.com/support/knowledgecenter/POWER9/p9haj/sal.htm).
h) If necessary to view the identify LEDs or to manage cables at the rear of a rack-mounted system,
open the cable management arm by completing the following steps:
1) Release the mounting bracket from the cable management arm assembly by pressing the
indentation (A) on the inner cable management arm tab. The cable management arm releases
from the outer mounting bracket in the direction shown.
