Can't replicate and sync back!

Article ID: 302

Last updated: 29 Apr, 2009

Problem:

The system had a failover incident. It fails over to the secondary system without any issue. But when trying to failback the volumes they did not get synchronized and I could not failback.

Symptoms:

Trying to create a new failover task and got "error 25 - No destination volume found." Under the volume replication task primary and secondary systems have Destination mode.

Solution:

The recap for the problem was:

* Turn off iSCSI Failover Manager on Primary

* Disable all iSCSI Failover Tasks on Primary & Standby

* Delete all Volume Replication Tasks on Primary

* Toggle Volume Replication bit for each Logical Volume on Primary & Standby (don't Initialize!)

* Create all Volume Replication Tasks on Primary

* On Standby Only, change each Volume Replication Volume to destination mode

* On Primary Only, start all volume replication tasks

* On Primary Only, add all Volume Replication Tasks to the Failover Manager

* On Primary Only, start iSCSI FailOver Manager
