We created a 50GB Vdisk with one Virtual machine of 10GB on it.
We started replication from one site to the other which took about 2-3 hours.
When we failover to the other side, HP CA start sycning the other way and replicates the entire Vdisk to the original side, knowing that the data is 99% the same. So, every time we failover/failback the Vdisk is replicated entirely (we presume)
Is this normal behaviour? I thought that HP CA would Check what's left of the LUN on the source side and only move the delta's?
?
Solved! Go to Solution.

Re: HP Continuous Access Behaviour
Distance between sites is 50-60km.
When we failover to the other side, it takes about 1,5 hours to synchronize towards the original side, knowing that there is only 1 Virtual Machine on the LUN which hasn't changed.
Tested this a few times today.

SolutionRead the RSM user guide, it's the best way to understand Continuous Access.

Look for "PLANNED failover"

Re: HP Continuous Access Behaviour
You we're correct. There is a difference between Planned and Unplanned failover... Since we were using Vmware Site Recovery Manager to do the failover the process was automated... didn't catch it.
Thx... close case.
