Fields

Array status

This value reflects the current array status. A description of the array status is displayed in the Details column. For example, if the status is "Assigned," the description contains the assigned rank number. This value will be one of the following:

• 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 disk drive modules (DDMs) indicated by the disk serial numbers attribute are not in the normal state.

Data state

This value reflects the current data status. A description of the data status is displayed in the Details column. This value will be one of the following:

• Normal — The array is in the Normal data state if none of the other data states applies. This status applies if the array is unassigned.
• Degraded — The array is in the Degraded data state if both of the following conditions exist:
  • The Read-only, Failed, Repairing, or Inaccessible data states do not apply
  • One or more redundancy groups are rebuilding (that is, there is a DDM with a rebuilding state in the array)
• Read Only — The array is in the Read-only data state if all of the following conditions exist:
  • The Failed, Repairing, and Inaccessible data states do not apply
  • One or more DDMs have failed
  • There are insufficient spares to support all rebuild operations
  • Continued write operation without redundancy could result in data loss
• Failed — The array is in the Failed data state if all of the following conditions exist:
  • The Repairing and Inaccessible data states do not apply
  • Two or more DDMs in the array have failed
  • There are insufficient DDMs left in the array to rebuild the data that was lost on the failing storage devices
  All data on the array has been lost.
• Repairing — The array is in the Repairing data state if all of the following conditions exist:
  • The Inaccessible data status does not apply
  • The array has previously entered the failed state
  • The repair array function has been accepted
  • The repair array function has not completed
  The data status returns to Normal if the array repair completes successfully, or it returns to Failed if the array repair action completes unsuccessfully.
• Inaccessible — The array is in the Inaccessible data state if the storage unit cannot access a set of storage devices that are sufficient to access all the data on the array.

DDM state

This value reflects the current DDM status for all DDMs in the array. A description of the DDM status is displayed in the Details column. For example, if all DDMs are Normal, DDM state is Normal. (If one of the 8/16 DDMs in the array is not normal, the table is presented with Serial Number, State, and Description fields.) This DDM state value will be one of the following:

• 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.
• 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 unit.
• Verifying — The DDM is made 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.
• New — The storage device is new and integration of the DDM into the system has not begun.
• Missing — The storage device is missing. The DDM has been pulled out from the system and removal has not been processed by the system.
• 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.
• Removed — The storage device is removed. The DDM is not in the system and its removal has been processed by the system.
• Prepared for service — The storage device is prepared for service (for example, going offline or quiescing). The DDM can safely be pulled out without causing any adverse effects.
• Missing, failed — The storage device is missing and the previous state of the device was “Failed” before it was pulled out.
• Removed, failed — The storage device is removed from the system and removal has been processed by the system. The previous state was “Missing, failed.”
• Inappropriate — The storage device is inappropriate for the system. For example, a storage device that is of the wrong capacity or RPM. The DDM is not failed as it may be valid for other systems and locations.
• Interfailed — The resource is operational, but faulty. The resource will fail soon and should be replaced as soon as possible.
• 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.
