Volume replicator hangs the system
I have Veritas Storage Foundation HA/DR with VVR option. I did all the installation, configuration, setup and replication when both main site servers and DR site server were located in one location with 100 Mb/s bandwidth.
Before moving the DR server to remote location, We decided to simulate the environment and changed the bandwidth into the real available bandwidth that will be in future (2 Mb/s).
There is no more than 3 GB daily changes at main site and we had no problem before applying (End of Day) patch that makes 1 GB changes in less than 5 minutes which caused the Veritas replicated volumes to hang despite the replication mode is Asynchcronous. When applying the same patch with 100 Mb/s bandwith we had no problem.
Veritas Storage Foundation version is 5 MP2 and the operating system is Linux RHEL 4 x64.
