One virtual disk in multiple host groups?
I have an MD3220i connected to 2 R720's running EXSi 5.1 and an R610 with windows 2012R2. I have Veeam installed on the windows box for backups and replication. Currently all 4 virtual disks are mapped to the same host group that includes all 3 servers. I am wondering if it is possible to map a virtual disk to more than one host/group? Veeam needs read access to the VMFS Luns to do what it needs, but not write, and i would rather the NTFS LUN used by Veeam was not seen by vmware. I cannot figure out a way to have 3 LUNs read only by one host and R/W by the other 2. As far as i can tell everything has to be in the same group to work properly. Is any of this possible? Thanks!

Hello dsoward,
With the MD3220i you can map a Virtual disk to multiple host in the same host group but you can’t have a virtual disk owned by 2 different host groups. What I have seen some customer do is to make it so that luns that are needing to be backed up are present to your backup server & given a drive letter so it can read them but the luns are not brought online to the backup server.
Please let us know if you have any other questions.
