Volume group auto mount on DR host when device is in sync state
Volume group automatically get imported on DR VM guest even when SRDF device in synchronized state and
not showing any new change data. When SRDF disk is in split state something is writing from server to disk and disk shows R1 Invalid tracks.
VM Guest : Red Hat 6.2
ESX Version : VMware ESXi 4.1.0 build-9
As per EMC support there is no issue with EMC rdf disks. Can someone please help us finding why Red hat VM
not updating disk status in DR (R2 Disk) . We also tried rebooting both VM ( Prod-DR ) but still having same issue.

When SRDF is replicating, the R2 may validly be on one of two states. Either Write Disabled (WD) or Not Ready (NR).
A WD device is ready to the channel and any volume manager that supports read-only devices can mount it. Sometimes this is preferable. If you don't want to have your host mount the R2 while SRDF is active, just not ready the devices...
symrdf -g not_ready R2
If you do have R2's mounted while RDF is replicating, the file systems MUST be unmounted and re-mounted when RDF is split in order for the file system to get the current view of the device.
If you want to stop SRDF replication, without affecting the NR/WD of the R2, issue an SRDF SUSPEND instead of SPLIT.
