Another weird problem here, just looking for some places to start / where to look to troubleshoot further, or just open a ticket.
I have two exchange mailbox servers, with RDM's hosted on a netapp, using snap manager for exchange.
The RDMs for each machine are presented via hardware iScsi, each of the 4 esxi hosts has access to and can see all the individual luns.
when i initiate a migration for machine one, it validates on 3 of the 4 hosts, but the 4th host returns a validation failure due to an inaccessable RDM (verified that disk/lun shows up on said host).
the second machine, same deal, except a different lun, and a different host fails validation (so 3 of the 4 still work fine). again everything i can see in storage suggests the lun is presented properly, and visible to that host.
Have the netapp tools installed on the vCenter server. when i look at the 'problem' luns in the netapp tools, they also show those luns as being presented and accessable from all 4 hosts.
I realize there could be an issue here with netapp, or esxi, but again, looking for some additional pointers for where to look next to troubleshoot this.
Thanks
Jared
