  • Help in Creating Raid5 in virtual machine via Pass thru disk

    Please help me to create raid 5 disk in virtual machines which is in failover cluster attached to SAN storage.I want to create Raid 5 of 300 GB in virtual machine via pass thru disk.I tried creating Failover cluster disk in hyper V host and then assigned it to the virtual machine as pass thru disk .Everything worked fine & I was able to create Raid 5 of 300 GB via (3) disk of 300GB under Raid 5, but the next day the machine goes into missing state in hyperV & I have to import it again.All hardware req of Hyper V host is fine with plenty of available resources

    If the storage is on a SAN, surely high availability will be handled by the SAN OS? Apart from "practicing" I cannot see any point in creating software RAID on top of hardware

      Yes, the storage is on SAN , so does it mean tht RAID5 on vm is not require if the storage is already on SAN???

        No, what's the point? RAID5 gives you disk redundancy, but you already have that because the disks are located on a SAN, aren't they?

          Normally yes, but it depends on how the storage on the SAN is configured
