HP StorageWorks Data Replication Manager commands
HP StorageWorks Data Replication Manager (DRM) uses the peer-to-peer remote
copy function of the HP StorageWorks HSG80 Array Controller to achieve data
replication. HSG80 Array Controller pairs at the initiator site are connected to a
partner HSG80 Array Controller pair at the target site. Remote copy sets are
created from units at the initiator and target sites. These remote copy sets are
mirrors of each other.
HSG80 Array Controllers provide failover and failback capabilities in case of
failures. Failover makes the data available at the target site after a failure. Failback
is used to move data operations back to the initiator site after the site is back
online.
Note: All DRM commands are hidden and inoperative until the controller pair is put
into Remote Copy mode by specifying the REMOTE_COPY switch of the SHOW
controller command (see page 256).
DRM applies only to HSG80 Array Controllers running ACS V8.8-
x P.
The CLI commands used to configure a DRM environment, and for failover and
failback procedures include:
■ ADD ASSOCIATIONS
■ ADD REMOTE_COPY_SETS
■ ADD SNAPSHOT_UNITS
■ DELETE association-set-name
■ DELETE remote-copy-set-name
■ SET association-set-name
■ SET remote-copy-set-name
■ SHOW ASSOCIATIONS
