Impact of enabling bi-directional replication
Folks,
I have inherited the management of two Gen4 clusters running CentraStar 4.0.x.
Bi-directional replication was set-up as follows by EMC:
C1 -> C2 active
C2 -> C1 paused
We want to test our DR process by taking C1 offline and forcing the application, Enterprise Vault, to write to C2. Once the test is over and C1 is online can I resume C2 -> C1 replication to get any changes copied back to C1?
Infact can I resume C2 -> C1 replication prior to taking C1 offline anyway and leave it running permanently?
Regards,
Paul Esson

Configured a site recently with replication setup between 2 Centeras bidirectionally (between a Pool at each site).
worked fine. We had replication set to 'Enabled' in both directions, the application was DiskXtender.
We wrote to 1 site, waited for data to replicate to the DR site, checked the DR site for the replication - was good.
Then failed over the application to the DR site (now the new Primary), wrote to the new primary site, and looked at the other site for replication - was fine.
Then failed back to the original primary site.

Hi
As Informatio we monitor roughly 35 Centera systems. All the replicated systems are setup with bi-directional replication as it simplifies failover and failback scenarios and eliminates manual tasks to be performed in case of disaster.
