A RAID 6 SAFE key has been imported to the storage array on a set of foreign drives, and the storage array is now out of compliance; or the RAID 6 SAFE key has been removed, and there are still RAID 6 volume groups present in the storage array (i.e., “not within limits”).
What Caused the Problem?
The RAID 6 Premium Feature is out of compliance.
This problem can occur in the following scenarios:
Scenario 1 (Most common scenario)
- The current number of RAID 6 arrays on the storage subsystem exceeds the number of RAID 6 arrays allowed. See the Important Notes for more detail on this scenario.
Scenario 2 (Less common scenario)
- You connected drives to one or more controllers where 1) the controllers were NOT previously attached to any drives and 2) the drives were already previously configured while attached to other controllers where the RAID 6 feature was supported and enabled. In this Scenario, you can get this problem even if there are no RAID 6 arrays on the storage subsystem. See the Important Notes for more detail on this scenario.
The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
Important Notes
This problem can occur if you disable a Feature Pack key. Disabling a feature pack key can result in multiple individual features transitioning to an Out of Compliance state since you may have globally lowered the limits supported by the storage subsystem. If there is a Feature Pack Out of Compliance problem in the Summary Area, complete those recovery steps first. If this problem still appears after you complete the Recovery Steps for the Feature Bundle Out of Compliance problem, then proceed with the Recovery Steps below.
Scenario 1 typically happens because you:
Disabled the RAID 6 feature while RAID 6 arrays are still present (in other words, the storage subsystem allows zero since the RAID 6 feature is disabled, and you currently have more than 0)
Enabled or Disabled a Feature Pack resulting in the storage subsystem allowing less RAID 6 arrays than are currently present on the storage subsystem (See first bullet, above)
Inserted drives that contain one or more RAID 6 logical drives into this storage subsystem and the RAID 6 premium feature is NOT enabled on the storage subsystem.
Scenario 2 happens because the controllers were not previously attached to drives, so the controllers 'adopt' the configuration database of the first drive they encounter. When drives are adopted by the controllers, the configuration database contained on the drives (which includes all of the information about the previous storage subsystem, including the Enabled/Disabled information of features) is used by the controllers. Therefore, the information in the configuration database shows that the RAID 6 feature is enabled, but the feature is either disabled on this storage subsystem or not supported by the controllers. If the controllers had been previously attached to drives and then another set of drives are added, then the new drives would be 'imported' (overwriting the configuration database) rather than 'adopted' since the controller is using the configuration database of the existing drives.
For Scenario 1, you can fix this problem in two ways:
You can enable the RAID 6 feature key
You can remove RAID 6 arrays
For Scenario 2, you can fix this problem in two ways:
You can disable the RAID 6 feature once all of the RAID 6 arrays have been removed
You can enable the RAID 6 feature key if it is supported by this storage subsystem
The following events will occur while this feature is in an Out of Compliance state:
This storage subsystem will remain in a Needs Attention state
A critical event will be logged once every 24 hours
Alert notifications will be sent, if configured
You will NOT be able to:
Create new configuration objects (Automatically or Manually) - such as logical drives, flashcopies, mirror relationships, logical drive copy pairs, and storage partitions
Assign hot spares
Change the segment size of a logical drive
Change the RAID level of an array
Expand the capacity of an array or logical drive
