The way we have our SAN cut is front end Celerra handing out NFS file systems visible to our 5 ESX hosts (one is actually ESXi). Anyway, physical luns are only handed out to our physical servers, so my question is, can I setup a cluster where the settings for the disks are associated with an iSCSI id in vSphere as physical to be shared across VMs? So far, running the MSCS validation, once I was able to get it to verify properly and all other times it has reported a failure on "SCSI-3 Persisten Reservation". I've seen a lot of threads on the forums about this, mostly ones that are a bit older (e.g. http://communities.vmware.com/thread/174541).
My option for RDM is greyed out when setting up the disk, so I am having to set the SCSI controller (LSI Logic SAS) in vSphere to Physical and then just pointing the second VM to this same VMDK. So far, no go. Like I said, it passed validation once, not sure why, because I came back in the next day and it is no longer passing validation.
I have a DRS rule to keep the two VMs on separate hosts and the datastore is accessible (r/w) by all hosts.
Any help is greatly appreciated again.
Thanks,
Izz
