ASP_DEVICE

VARCHAR(10)

The name of the Auxiliary Storage Pool (ASP) group the HyperSwap status is for. Possible values are:

*SYSBAS
HyperSwap status is returned for disk unit pairs in the System ASP (ASP 1) and the User ASPs (ASP numbers 2 through 32).

name
The name of an Independent ASP device description for a primary Independent ASP.

UNIT

INTEGER

The disk unit identifier.

STORAGE_TYPE

VARCHAR(3)

The type of storage for the session. Possible values are:

ASP

ASP Session (DS8000 or Geographic Mirroring)

CSM

CSM ASP Session

SVC

SVC ASP Session

FIRST_STORAGE_IDENTIFIER

VARCHAR(20)

Nullable

The unique identifier for the storage device that a logical unit (volume) resides in. Possible values are:

name
The name of the source storage identifier.

Contains the null value if HyperSwap status is not known for the device on this node. This could be due to a failure communicating with the node, or because the node is not active in the cluster, or HyperSwap is not configured.

FIRST_STORAGE_ACCESSIBLE

VARCHAR(3)

Nullable

Whether the storage device is accessible or not. Possible values are:

YES

The storage device is accessible.

NO

The storage device is not accessible.

Contains the null value if HyperSwap status is not known for the device on this node. This could be due to a failure communicating with the node, or because the node is not active in the cluster, or HyperSwap is not configured.

FIRST_VOLUME

VARCHAR(4)

Nullable

The unique volume identifier for the logical unit within the storage
device.

Contains the null value if HyperSwap status is not known for the device on this node. This could be due to a failure communicating with the node, or because the node is not active in the cluster, or HyperSwap is not configured.

SECOND_STORAGE_IDENTIFIER

VARCHAR(20)

Nullable

The unique identifier for the storage device that a logical unit (volume) resides in. Possible values are:

name
The name of the source storage identifier.

Contains the null value if HyperSwap status is not known for the device on this node. This could be due to a failure communicating with the node, or because the node is not active in the cluster, or HyperSwap is not configured.

SECOND_STORAGE_ACCESSIBLE

VARCHAR(3)

Nullable

Whether the storage device is accessible or not. Possible values are:

YES

The storage device is accessible.

NO

The storage device is not accessible.

Contains the null value if HyperSwap status is not known for the device on this node. This could be due to a failure communicating with the node, or because the node is not active in the cluster, or HyperSwap is not configured.

SECOND_VOLUME

VARCHAR(4)

Nullable

The unique volume identifier for the logical unit within the storage
device.

Contains the null value if HyperSwap status is not known for the device on this node. This could be due to a failure communicating with the node, or because the node is not active in the cluster, or HyperSwap is not configured.

STORAGE_AFFINITY

VARCHAR(3)

Nullable

Whether the affinity of the storage device is used or not. Possible values are:

YES

The affinity of the storage device is used.

NO

The affinity of the storage device is not used.

NOT DEFINED

The affinity of the storage device is not defined.

Contains the null value if HyperSwap status is not known for the device on this node.

PRIMARY_STORAGE_IDENTIFIER

PRISTGID

VARCHAR(20)

Nullable

The unique identifier for the storage device that a logical unit (volume) resides inis the primary storage device in the HyperSwap relationship. Possible values are:

name
The name of the source storage identifier that is the primary in the HyperSwap Relationship.

Contains the null value if the HyperSwap status is ‘TWO PRIMARY’ or if the HyperSwap status is not known for the device on this node. This could be due to a failure communicating with the node, or because the node is not active in the cluster, or HyperSwap is not configured.

COPY_STATUS

VARCHAR(20)

Nullable

The status of the HyperSwap relationship as reported by the IBM System Storage Device. Possible values are:

ACTIVE-SYNCHRONIZED

The HyperSwap relationship for the volume is active and all of the copies of the volumes are synchronized.

SUSPENDED

The HyperSwap relationship for the volume is currently suspended.

RESUMING

The HyperSwap relationship for the volume is currently resuming.

TWO PRIMARY

The HyperSwap relationship for the volume consists of two primary volumes.

STORAGE FAILURE

There are problems when communicating with the storage devices.

NOT CONFIGURED

The HyperSwap relationships are not configured on this node for the volume.

Contains the null value if HyperSwap status is not known for the volume on this node.

COPY_PROGRESS

INTEGER

Nullable

The percent of synchronization complete between source and target. If the COPY_STATUS is RESUMING, it is the synchronization progress. If the COPY_STATUS is ACTIVE-SYNCHRONIZED, it is 100. Otherwise, it is 0.

Contains the null value if HyperSwap status is not known for the volume on this node.
