Identifying the Failed NVMe from the Console
▶ To identify the failed data drive, you can use the nvsm command:
sudo nvsm show health
View the command output and look for drive alerts to identity the failed drive.
Alternatively, you can use the BMC web user interface to access the Sensor screen, the IPMI event
log, and the System log to identify issues with the U.2 drives.
