Recovering from Disaster for 1-to-1 Configurations
Follow these failover and recovery guidelines to recover from system failure.
Failover in 1-to-1 Remote-Copy Configurations
1.
Reverse the role of all volume groups on the system that is still in normal operation (the failover
system). On the failover system (System2), issue the following command:
# setrcopygroup failover -t
where
The setrcopygroup failover -t command:
•
Changes all secondary volume groups on the failover system (sync_group_1.r96 on
System2
) to primary volume groups, and therefore reverses the direction of data
replication
•
Enables I/O to the reversed volume groups (sync_group_1.r96)
NOTE:
If you do not want to perform disaster recovery operations on all volume groups on
a system, you can use all of the disaster recovery commands on one or more specified volume
groups. For more information, see the description of each command in
