Does RP4VM support protection of Microsoft Cluster nodes?
I see the following statement in the RecoverPoint for Virtual Machines 4.3 documentation:
RecoverPoint for VMs does not support shared or non-persistent devices.
What is precisely meant by "shared" devices? Does this include Microsoft Cluster nodes that use Physical Bus Sharing and shared RDM mapping files? In other words, does EMC support using RecoverPoint for VMs to protect traditional "single copy cluster" (MSCS) with Physical Mode RDMs using Physical Bus Sharing?
Thanks,
Bill

Bill,
Currently, RPVM doesn’t support shared VMDKs or RDMs where the disks are mapped to multiple VMs. I am not familiar w/ the ‘single copy cluster’ configuration, can you plz elaborate?
Thx,

A single copy cluster is a traditional MSCS cluster. Basically node 1 has Physical Mode RDMs using SCSI Bus Sharing, pointing to LUN1, LUN2, and LUN3 for examples. Node 2 also has Physical Mode RDMs using SCSI Bus Sharing, pointing also to LUN1, LUN2, and LUN3. The MSCS software controls which VM has read/write access to the LUNs, and failover is performed inside the Guest OS. Is this supported by RP4VMs? Here is the VMware configuration guide for MSCS clusters:
