OK so we had a planned powerdown this last weekend to add additional power.
We have a VMware ESX Server 3i, 3.5.0, 123629 and an HP MSA 1500.
Before the downtime everything was working perfectly and we had close to a dozen production VM's on a 585 GB area on the MSA 1500. It was given a LUN ID #1 and connected to the ESXi server via Fiber Channel through a fiber switch.
Now when we powered the ESXi server up all the VM's in the inventory show as "Unknown (inaccessible)". Under (Configuration > Storage) we don't see the 585 GB datastore. If I click "Add Storage..." and select "Disk/LUN" and click next it shows:
Device: vmhba2:0:1 Capacity: 585.94 GB Available: 585.93 SAN Identifier: 50:05:08:b3:00:92:ca:79 LUN: 1
If I click next in the wizard it says "The hard disk is blank." Uh no! I know that disk wasn't blank!
I certainly don't want to proceed with the wizard and format wiping out all our production VM's! How do I recover from this catastrophe?
Thanks for any help you can provide...
