Identifying the location of the PCIe adapter by using the slot number

The error message provides information to help you to determine the location of the PCIe adapter.
About this task
For example, the log might contain an error message similar to the following text:
[131779.752714] EEH: PHB#0 failure detected, location: Slot5
Replace the PCIe adapter. Go to "8335-GTC, 8335-GTG, 8335-GTH, 8335-GTW, or 8335-GTX locations"
on page 25 and use the slot number information in the operating system log to identify the physical
location and the removal and replacement procedure.
Service action
1. If the NVMe Flash adapter has an amber LED that is flashing or is on solid,
replace the adapter. Go to "8335-GTC, 8335-GTG, 8335-GTH, 8335-GTW, or
8335-GTX locations" on page 25 to identify the physical location and removal
and replacement procedure.

4. Type the following command and press Enter:
nvme smart-log /dev/nvmeX, where nvmeX is the resource name of the
NVMe Flash adapter.
Check for problems with the critical warning, temperature, available spare,
percentage used, power cycles, or power on hours fields.
Note: For more information about nvme commands, type man nvme and press
Enter.
