I have 2 servers connected to a shared storage array using Fibre Channel. Currently there are 2 luns on the storage device.
From the Failover Cluster Manager, when I select “Add Disk” from Storage – Disks, both luns show up and I can add them without problems. But if I choose to only add one of them first (it doesn't make a difference which one is added first), then it will not allow adding the second one later. I get a message: "No disks suitable for cluster disks were found. For diagnostic information about disks available to the cluster, use Validate a Configuration Wizard to run Storage tests."
When I do add one (or both disks at the same time), they work just fine for failover clustering.
I can’t imagine this is by design. Is this a known/unknown issue, or is there something special that needs to be done?
Thanks
