There are 3 active alerts.

Cause

The root cause of the issue is the failure of a process related to disk firmware upgrade, which results in the disks being marked as failed.

  • The relevant script fails to receive a Resume request within 5 minutes of a Suspend request, causing the disks to be marked as failed.

Resolution

A fix for this issue has been identified and will be integrated into future versions of DDOS 8.3.x.
Until then, a Minimal Disruptive Upgrade (MDU) must be applied.

The MDU and relevant instructions can be found here (Dell Customer Login is required).

Note: Failed disk must NOT be replaced in this situation - these failures are addressed as part of the recovery actions and workaround.
