array_id

STRING

Array ID

arsite_id

STRING

Array site ID

da_pair

STRING

Device adapter pair ID that is associated with the specified device adapter

data_state

STRING

Current data state

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).

ddm_capacity_gb

NUMBER

Minimum disk capacity (10^9B) of the storage devices (DDMs) in the designated array in gigabytes

ddm_capacity_kb

NUMBER

Minimum disk capacity (10^9B) of the storage devices (DDMs) in the designated array in kilobytes

ddm_rpm

NUMBER

Minimum disk rpm of the DDMs in the designated array

disk_class

STRING

Disk class is either high speed fibre-channel disk drives or near-line disk drives

ENT - Specifies enterprise and represents high speed fibre-channel disk drives

NL - Specifies near-line and represents ATA (FATA) disk drives

disk_interface_rate

NUMBER

Minimum disk interface rate of the disks in the designated array

disk_interface_type

STRING

Disk interface type of the DDMs in the designated array

ibm_array_id

NUMBER

Foreign key to array details

ibm_array_site_id

NUMBER

Foreign key to array site details

ibm_device_adapter_id

NUMBER

Foreign key to device adapter details

ibm_storage_system_id

NUMBER

Foreign key to IBM storage system details

last_update

DATE

last updated date

raid_type

STRING

Type of RAID array (5 or 10) and the array configuration (for example, 6+P)

serial_nbr

STRING

Unique internal identifier for the data space of the designated array

state

STRING

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) that are indicated by the disk serial numbers attribute are not in the normal state.

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.

Repairing - The array is in the Repairing data state if all of the following conditions exist: The Inaccessible data state 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.

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.

system_name

STRING

name assigned to the storage unit
