position

NUMBER

DDM position in an array site configuration of DDMs

state

STRING

Current DDM state.

One of the following values are displayed:

Normal - The storage device is operational and functional in its current disk usage.

New Indicates the initial state when a DDM is inserted or first discovered.

Installing A new storage device has been identified.

Verifying - The storage device is made accessible to the device adapter, its characteristics are determined, cabling is checked, and diagnostics are run.

Formatting - A verified storage device requires low-level formatting and the formatting operation is in progress.

Initializing The storage device is being initialized with all zero sectors.

Certifying -The storage device is read-accessed to determine that all sectors can be read.

Rebuilding - The storage device is being rebuilt with data from the array that it is associated with.

Migration - Target DDM migration is migrating another array member storage device to this spare storage device.

Migration Source DDM migration is migrating this array member storage device to another spare storage device.

Failed - The storage device has failed and an immediate repair action is required.

Failed - Deferred Service - The storage device has failed and a repair action is not immediately required.

Removed - The storage device is removed from the system and removal has been processed by the system.

Inappropriate -The storage device is incompatible with the system; for example, a storage device that has the wrong capacity or rpm. The DDM is not failed, because it can be valid for other systems and locations.

Inter failed - Indicates that the DDM is faulty but still working.

PFSed - Indicates that the DDM is prepared for service, and ready to be removed without impacting the system
