We are migrating between SANs and we are currently trying to figure out how do we move a Windows 2008 R2 Cluster.
The MS cluster is formed by 2 VMs:
Each node has 1 OS drive which is a virtual disk sitting on a VMFS datastore and 2 RDM.
We have used EMC Open Migrator in order to move the RDM disks to the new SAN. So at this point we have each node in the cluster running the OS VM disk in the old SAN (datastore) and the cluster RDMs are now moved to the new SAN.
Would it be possible to use Storage vMotion to move each one of the vdisk with the OS from one SAN/Datastore to a new datastore in a new SAN without affecting the RDM that we have already moved?
