I know that the quorum disk cannot be a member of shadow set but I dont
know if can be member of virtual array.
Any comment about that..?
Thanks

Edgar,
We have a RAID(1+0) quorum disk in an MSA1000 array.
Works sweet with v.7.3-2

A logical unit made from an EVA virtual array will work just fine as a
quorum disk. It can be vRAID1 or vRAID5 and that's OK because VMS just
sees it as a single disk unit; the mirroring or RAID-5 protection is
hidden from VMS.
This restriction is only with respect to host-based volume shadowing. |

Edgar,
I have storage on HSG80's so I can't say for certain about EVA's. The
quorum disks for two of my clusters are on DGA devices served by the
HSG80's and I have no problems. As far as I know VMS won't see the
virtual array any differently. Don't forget to format the drive as a
VMS volume first, though. Either ODS-2 or ODS-5 will work.
