Hi All

We have site -A (Live) and site-B (Disaster Recovery).

Database is replicated to site-B using EMC SRDF/A links.

We use Veritas global cluster manager to monitor/control the failover.

Global failover is set to manual not automatic. i.e. Manually DNS entries has to be updated. so that services can be pointed towards the surviving site.

To start the databases at site-B ( DR site) 1. SRDFA links should be made split.
2. After (1) above database is started at DR site.

Question:
a) What if site -A ( live) is operational and site-B( DR) is in sync with site-A through SRDFA links.

Next if accidently databases at DR site are started without splitting the SRDFA links, does that will dismount

the SAN file system at site-A( live) and hence bring down the live databases?

Regards
