Data Replication Manager (DRM) Commands
DRM uses the peer-to-peer remote copy function of the HSG80 controller to achieve
data replication. HSG80 controller pairs at the initiator site are connected to a partner
HSG80 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.
The HSG80 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 once 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 SET controller command.
DRM applies only to the HSG80 array controller running ACS version 8.7P.
The CLI commands used to configure a DRM environment and for failover and
failback procedures include:
