ESXi 5 infrastructure, OES2 (NW 6.5.8) VM with vRDM iSCSI SAN LUNs

SAN array does Snapshot, which works great if one were using Windows to
access it (physical or VM) as per:

But with NSS volumes I expect it to be way more troublesome

Ofcourse I can bring snapshot online, rescan ESXi storage, could even hot
add to running OES2 VM, but the volume name would be the same, so OES2 would
most likely get a fit, am I right?
