Flashes (Alerts)
Abstract
When a SED Opal device is reverted by using the "nvme sed revert" command without the -e flag, then the drive is not fully reverted. In this case, any attempt to re-initialize the device by using the "nvme sed initialize" command results in a failure.
Content
Linux Releases Affected
Red Hat Enterprise Linux (RHEL) 9.4
SUSE Linux Enterprise Server (SLES) 15, Service Pack 6
IBM Systems Affected
All systems that support NVMe drives
Symptoms
NVMe SED drive cannot be re-initalized after it is reverted by using the following command without the
-e flag:
nvme sed revert
Workaround
The only workaround for this issue is to revert the NVMe SED drive by using the following command:
nvme sed revert -e
When the NVMe SED drive is reverted by using the revert -e option, then the contents of the NVMe SED drive is erased. You must take full backup of the NVMe SED drive before the nvme sed revert -e command is issued. After the nvme sed revert -e command is issued, it is possible to re-initialize the NVMe SED drive and restore the backed up data.
Fix Outlook
Fix will be included in the upcoming maintenance releases.
I/O device impacted
All SED compliant NVMe drives.
