C.9 Bidirectional Synchronous Disaster Recovery Example
InForm OS Version 2.3.1 Remote Copy User’s Guide
To initiate disaster recovery for a bidirectional Remote Copy pair with synchronous volume
groups:
1 On the failover system, make all secondary groups primary by reversing the direction of the
failed targets for each group. Issuing the setrcopygroup failover command switches
every secondary group for the specified target. For this example, this is done by reversing
the failed target InServ1 for the secondary group sync_group_1.r96 on InServ2
using the setrcopygroup failover command as follows:
On InServ2:
# setrcopygroup failover -t InServ1
NOTE: At this point, you can export read-write volumes from the secondary. Any
volumes already exported can now accept writes.
