Synchronous Long Distance Remote Copy Disaster Recovery Example
Remote Copy User’s Guide
InForm OS Version 2.3.1
1
Initiate disaster recovery to the asynchronous periodic backup server, InServC, by issuing
the
setrcopygroup failover
command on InServC.
By issuing
setrcopygroup failover
as shown in the example above:
◆
The disaster recovery operation is run against all groups that were secondary groups to
InServA.
◆
All tasks required for each group to be processed are displayed as is the status of each
task. This can take several minutes to complete.
◆
By default, the
setrcopygroup failover
command attempts to pull any newer
data from the synchronous backup server (InServB). In doing so, InServB temporarily
assumes the role of the primary storage server.
# setrcopygroup failover -f -t InServA
