Symptoms

D@RE keys are not properly assigned to drive.

Cause

Dell Technologies has identified a rare condition that can occur on systems running PowerStore 2.0.0.0 code. This condition can be introduced through the following events:
  • Remove a disk and reinsert the same disk after 5 minutes.
  • Insert a new disk as a replacement for a failed disk.
  • Add new disks as part of a capacity upgrade.
Once introduced a data impactful event can occur after certain High Availability Events (Node Reboot, Node Replacement, and so on). This impact results in data on the disk or disks in the above activities to be compromised.

Resolution

  • To prevent any risk of this issue, we recommend you upgrade to the PowerStoreOS 2.0.1.0 or later code immediately.
  • If you are on 2.0.0.0 code and are replacing a drive, Please follow these steps:

  1. Remove drive from chassis.

  2. Allow rebuild to complete.

  3. Perform upgrade to the PowerStoreOS 2.0.1.0. 

  4. Replace faulted drive that was removed in first step.

  • If you have encountered the "encryption key check failed" error during a health check, do not reboot the nodes and seek immediate assistance, quoting this article.
