• Look for a flashing amber LED, which identifies the slot that was selected by using the identify
function.
g) Continue with step "10" on page 26.
8. To prepare to remove a PCIe adapter by using the Linux operating system, complete the following
steps:
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) Physically verify that the slot you identified is where you want to install the adapter.
• 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.
• Look for a flashing amber LED, which identifies the unoccupied slot that was selected by using
the identify function.
i) Use the Linux operating system drmgr command to prepare the adapter to be removed when the
system power is turned on.
1) Type the following command:
drmgr -c pci -r -s locationcode
Where locationcode is replaced with the location you identified earlier. For example,
U7879.001.DQD014E-P1-C3.
The following screen is displayed.
The visual indicator for the specified PCI slot has been set to the
identify state. Press Enter to continue or enter x to exit.
2) 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.
• Look for the flashing amber LED, which identifies the slot that was selected by using the
identify function.
