Issue

When a system using NVMe self-encrypting drives (SEDs or FIPS drives) loses access to the Onboard Key Manager (OKM) or External Key Manager (EKM), the required NSE authentication keys may not be restored.
In this condition, ONTAP could repeatedly attempt to unlock the drives even though the required key was unavailable. Repeated failed unlock attempts increment the drive lockout counter. If the counter exceeds the drive’s limit, the drives may become permanently locked and the data may become inaccessible.
This issue may occur after the drives are power-cycled or after repeated system reboots while access to the key manager is unavailable.
