I'd be interested in hearing the answer to this questiona as well. We also have a Dell (EqualLogic) PS5000XV SAN and in order to properly quiesce the snapshots for SQL and Exchange servers we must use the MS iSCSI initiator inside of the guest VM for the data volumes that SQL and Exchange are installed on and then use the Auto-Snapshot Manager Microsoft Edition (ASM/ME). The C: volume can still be stored like a normal VM on a VMFS shared volume.

In theory this might be possible if you could enable the functionality via a script (powershell for example) and place that script using a callout step in the recovery plan either as a command step or actually a post-power on vm step. Powershell can be used to invoke/run scripts within VM's and in the imminent update it can invoke bat files and vbs files as well.

From the SRM side SRM itself can only protect disks it can "see" vmdk's/RDMs.

SRM cannot "see" or manage disks visbile only when the VM is "ON" such as MSFT iSCSI disks as they are not visible until after a VM has been recovered and powered on and they are also not controllable via the SRA's.

hope that helps,
Lee
