Controller State: The array controller contains one or more logical drives with a RAID level that is not supported in the current configuration

Symptom

Controller State: The array controller contains one or more logical drives with a RAID level that is not supported in the current configuration. Any configuration command (e.g. logical drive creation, array expansion, etc.) or modification to the controller will result in the loss of all existing data on the disabled volume(s).

Solution 1
Cause

The configuration requires more drives than are currently supported.

Action
If this message is observed after moving a configured array of drives from another controller, do the following:
  1. Upgrade the firmware on this controller.
  2. Make sure that the cache module is installed. Install the cache module if not present.
  3. If the issue persists, power down the server and move the drives back to the original controller.
Solution 2
Action
If this message is observed without any drive movement, do the following:
  1. Make sure that the cache module is working.
  2. Replace the cache module, if required.
  3. If the issue persists, power down the server and move the drives back to the original controller.
  4. If the issue persists, contact Hewlett Packard Enterprise support.
