The command SHOW-STORAGE-CLUSTER-CONFIG INFORMATION=*STD informs you about the configuration and the status of selected or all present Storage Clusters.
With the INFORMATION=*VOLUMES parameter you receive information on the volumes used in the Storage Cluster. Two volumes, one volume of each storage system in the cluster, form a volume pair which is mirrored internally with the REC replication function.
Volumes of a Storage Cluster (generated in BS2000) are only displayed in the primary storage system. This also applies to a failure of the primary storage system or at manual failover.
The assigned volumes in the secondary storage system can be identified and displayed according to their volume number. They do not have a BS2000 mnemonic.
Volumes in a Storage Cluster are also specially marked at the output of volumes with the SHOW-STORAGE-CLUSTER-CONFIG command.
Volumes in a Storage Cluster are internally mirrored with REC. This internal mirroring is not displayed in the SHOW-REMOTE-COPY-STATUS command.
An additional replication of volumes in the primary storage system that is managed by SHC-OSD (see section "Replication of volumes of a Storage Cluster"), however, will be displayed.
The SHOW-STORAGE-CONFIGURATION INFORMATION=*STORAGE-CLUSTER command informs you on the configuration of Storage Clusters to a storage system.
The output for the INFORMATION=*PORT-STATUS parameter displays the assignment of the port to the primary or secondary storage system of a Storage Cluster.
In the SHOW-STORAGE-DEVICE-CONFIG command, information on the usage of volumes in Storage Clusters is also displayed. Especially, the usage as primary or secondary storage system is displayed in the column SCO.
