Figure 3-3: Initiator site failover
The cluster nodes at the target site must be rebooted after you perform the site
failover procedures.
Initiator Site Failback
When a new initiator site has been established or the original one restored, site
operation can resume after a failback procedure has been performed. A failback
procedure involves synchronizing both the initiator and target storage subsystems so
that operation can be returned to the initiator with minimal downtime. Verify that all
components at both sites are operational before performing a failback.
