Caution:
If you remove an NVMe drive without first powering it off, you can crash the
operating system. Oracle Database Appliance uses special commands to add or
remove NVMe storage.
The instructions describe how to replace an NVMe drive using the odaadmcli power on/off

The odaadmcli commands listed here must be run as the root user.

1.
# odaadmcli show disk
For example, the drive names pd_00 and pd_01 are seen by the host as NVMe0 and
NVMe1 and correspond to front drive slots 0 and 1, respectively.
Unmount and power off the drive to be replaced. Do one of the following:

the drive is lit.
