administrator. Taking the PCIe adapter offline prevents a service representative or user from
causing an unexpected outage for other users of the system.
b) Is the adapter you want to replace a PCIe3 x8 non-volatile memory SSD NVMe adapter?
• Yes: Continue with the next step.
• No: Continue with step "8.d" on page 30.
c) If you are replacing a PCIe3 x8 non-volatile memory SSD NVMe adapter and the logical partition
that controls the adapter is running the IBM i operating system, complete the following steps to
ensure that all of the namespaces in the NVMe device which are mirror protected disk units are
suspended from mirrored protection.
1) Start the IBM i System Service Tools (STRSST), and specify the user name and password.
2) On the System Service Tools (SST) display, select Work with Disk Units > Work with disk
configuration > Work with NVM Devices > Display NVM namespaces.
3) Locate the NVMe device that you are replacing by examining the Serial Number and Resource
Name.
4) Write down the ASP, Unit, and Resource Name of the disk units in the NVMe from the previous
step. Ignore any units which have an asterisk ( * ) in the ASP and Unit fields; those units are
non-configured and do not belong to an ASP.
5) Press F3 to return to the Work with Disk Units menu.
6) Select Work with disk unit recovery > Suspend mirrored protection > Suspend mirrored
protection. All of the disk units that can be suspended from mirrored protection are shown.
7) Type 1=Suspend in the option field for each disk unit in the list that you wrote down in step
"8.c.iv" on page 30.
Note: If any of the disk units in the list from step "8.c.iv" on page 30 are not shown on the
Suspend Mirrored Protection display, contact your next level of support. Do not remove an
NVMe that is in use because it can cause an unexpected outage.
d) Before hot-plugging adapters or storage devices, ensure that the file systems on those devices are
unmounted.
e) Ensure that any processes or applications that might use the adapter are stopped.
f) To identify the location of the failed PCIe adapter by using the IBM i operating system, complete
the following steps:
1) Type strsst on the command line of the Main Menu and then press Enter.
2) Type your service tools user ID and service tools password press Enter.
3) Select Hardware Service Manager > Packaging hardware resources (system, frames,
cards).
4) Type 9 (Hardware contained within package) in the System Unit or Expansion Unit field
of the unit where you are removing the card. Press Enter.
5) If you are installing a new PCIe adapter, select the option to Include empty positions.
6) Select Concurrent Maintenance on the card position where you want to remove the card, and
then press Enter.
7) Select the option to Toggle LED blink off/on. A light-emitting diode (LED) flashes identifying
the slot that you selected. Physically verify that this slot is the correct slot where you want to
remove the adapter.
g) 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.
