- Create a PPRC multi-target configuration.
- At site B, perform Failover to the TCz volume that is paired with site A.
- At site B, perform Failback to the TCz volume that is paired with site A.
The pair status at site A and site C changes to Suspend.
- Wait until the TCz pair status between site A and site B changes to Duplex.
In a PPRC cascade configuration, when the TCz pair status between site A and site B is Duplex and the TCz pair status between site A and site C is other than Suspend, the TCz P-VOL status in site A and site C changes to Suspend automatically when host I/O is started in site B.
