PowerStore: System Check detects drive invalid encryption band location for ENS24 enclosure

If the System Check detects any NVMe expansion enclosure (ENS24) drives with incorrect band offset, one of the following error messages is displayed:

• "<drive numbers> found with incorrect encryption band offset. (KB#000220624)"
  Drive(s) with incorrect encryption band configuration: <drive numbers> (KB#000220624

In the PowerStore Manager UI the issue detection appears as follows:


If the service script svc_health_check is used to perform this health check, the output is as follows:

The PowerStore health check (PUHC) may fail the validation, with the following error: ENS24 enclosure drives have encryption bands incorrectly locked. The health check is an off-release PUHC check that is contained in the Health Check thin package.

Example screenshot for PUHC:

A software issue in adding an NVMe expansion enclosure (ENS24) on the 500T platform results in incorrect encryption bands configuration.
With this mis-configuration of encryption bands, the security service may not be able to unlock the drives. Appliance services may be unable to come up after a power outage or a dual node reboot.

This issue is resolved if NVMe expansion enclosures are added in PowerStoreOS 3.6 and later. For NVMe expansions added on a 500T prior to 3.6, contact technical support as soon as possible for the resolution be applied.
