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

failover started with tasks: 6740
