Attributes

Data State

This shows the array state as normal or degraded.

Array status

This value reflects the current array status. The status can be one of the following values:

• Assigned — The array is assigned to a rank.
• Unassigned — The array is not assigned to a rank and all of the storage devices that are indicated by the disk serial numbers attribute are in the normal state.
• Unavailable — The array is not assigned to a rank and one or more of the DDMs that are indicated by the disk serial numbers attribute are not in the normal state.

DDM Serial Number

The 16-digit disk serial number.

DDM Location

The location of the storage enclosure and the DDM.

DDM State

One of the following states is possible:

• Normal — The DDM is operational and functional in its current disk usage. If it is configured as a spare or array member, there are no unusual operations in progress.
• New — The initial state after the DDM is inserted or discovered for the first time.
• Installing — A new DDM has been discovered. It is either a replacement DDM for a failed DDM or it is additional capacity that is being added to the storage image.
• Verifying — The DDM becomes accessible to the device adapter, its characteristics are determined, cabling is checked, and diagnostics are run.
• Formatting — A verified DDM requires low-level formatting and the formatting operation is in progress.
• Initializing — The DDM is being initialized with all zero sectors. This is required so that the DDM can be added to an array without regenerating parity.
• Certifying — The DDM is being read accessed to determine that all sectors can be read. If a bad sector is detected, an alternate sector replaces the bad sector.
• Rebuilding — Sparing has occurred and this formerly spare DDM is being rebuilt with data from the array for which it is now a member.
• Migration Target — DDM migration is migrating another array member storage device to this spare storage device.
• Migrating Source — DDM migration is migrating this array member DDM to another spare storage device.
• Failed — The storage device has failed and an immediate repair action is required. If spares are available, sparing has been initiated if this DDM was an array member.
• Failed - Deferred Service — The DDM has failed and a repair action is not immediately required. If this DDM was an array member, sparing has been initiated and there are sufficient spares at the time of this failure to allow the service to be deferred.
• Removed — The storage device is removed from the system and the removal has been processed by the system.
• Inappropriate — The storage device is not compatible with the system.
• Inter failed — The DDM is faulty but still working.
• PFSed — The DDM is prepared for service and ready to be removed without impacting the system.

DDM Usage

One of the following values is possible:

• Unassigned — The DDM is not assigned to an array site.
• Unconfigured — The DDM is assigned to an array site, but the array site is not configured and the DDM is not a required spare.
• Spare-Required — The DDM is assigned to an array site and is a required spare.
• Spare-Not Required — The DDM is assigned to array site that is configured with an array and a spare, but the spare is not a required space.
• Array Member — The DDM is assigned to an array site that is configured and the array site position of the DDM makes it part of the array.
