FAILBACK-STORAGE-CLUSTER Executes failback

Storage system:	ETERNUS DX/AF
Domain:	DEVICE
Privileges:	TSOS


/FAILBACK-STORAGE-CLUSTER executes a manual failback in a Storage Cluster. During this process, the server access is transferred transparently from the volumes of the secondary storage system to the volumes of the primary storage system of the Storage Cluster. The volumes of the primary storage system are reconstructed from the secondary storage system of the Storage Cluster.

Execution takes place on the primary storage system. The primary storage system has to be available.

The failback transfers all volumes of the secondary storage system. The volumes can but do not have to be generated in BS2000. BS2000 resources (pubsets, volumes, mnemonics) are not checked.

After a successful failback, the primary storage system again is the active storage system. The secondary storage system becomes the standby storage system.

The Command /FAILBACK-STORAGE-CLUSTER is refused with message NDE1608, if

• automatic Failover is activated and
• the FC path from the server to the pimary storage is not available

With this message you avoid that, because of the missing FC path, an automatic failover is executed directly after the failback. Dieser würde die Ausführung des /FAILBACK-STORAGE-CLUSTER wieder rückgängig machen.

FAILBACK-STORAGE-CLUSTER

CLUSTER-NAME = <posix-filename 3..16>

CLUSTER-NAME = <posix-filename 3..16>
Selecting the Storage Cluster by its name (see "Storage Cluster Option"). Abbreviations are alowed, at least 3 characters.
