4. To prepare the system to permanently remove an NVMe drive when the system is powered off,
complete the following steps:
a) Activate the identify function. For instructions, see Identifying a part (www.ibm.com/support/
knowledgecenter/POWER9/p9haj/sal.htm).
b) Physically verify that the slot you identified is where you want to permanently remove the NVMe
U.2 drive.
• 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 slot that was selected by using the identify
function.
c) Stop the system. For instructions, see Stopping a system (www.ibm.com/support/
knowledgecenter/POWER9/p9haj/crustopsys.htm).
