Environment
OS = Linux Redhat 6.2
Disk/Volume Manager = Veritas Storage Foundation(not LVM)
Storage Foundation version = 6.0 with RP1
Physical Disks = Three
DIsk 1 = This Disk is only for OS which is not under control of Storage Foundation
DIsk2 = This disk has two volumes to be replicated
Disk3 = This disk has two volumes for SRL
Volume Size of Disk2 = Volume1 is 140GB and Volume2 is 139GB
Diskgroup = one
Problem
In the Diskgroup I have made two volumes. I have configured replication and these two volumes are being replicated to DR Site properly. I have data in both volumes and my system is idle. But my second volume contineously shows that some data is being replicating to DR Site(always shows some data under SRL while repstatus command).
My question is how can I figure out that who is generating the I/O

might consider using a tool like iotop or htop to segreggate per-process IO to help you conclude

There is always some traffic in VVR for management information - specically timestamp. If your system is idle, if you run "vxstat -g diskgroup -i 5" (on primary or secondary), then you should see the SRL is the only volume that is written to and data volumes are not (the first figures output are writes since boot, but then vxstat will shows writes every 5 seconds). If this is the case, you know it is VVR generating the small amount of traffic.

'vxtrace' will give the pid of the originating process.
