ESXi 5 Add an existing lun to datastore without formatting

Question

We have two hosts running VMWare ESXi 5.1.0. Both are connected to a RAID 5 array via iSCSI.

The lun is an existing lun with vm on it but it is not reconized by the hosts after the reboot.

it is visible in vSphere Client in Configuration > Storage > Devices but not in Configuration > Storage > Datastores

Somebody have an idea how can we fix this ?

These are some commande we tried on the host

~ # voma -m vmfs -f check -d /vmfs/devices/disks/naa.60080e50002e0074000003975193cbf3
Checking if device is actively used by other hosts
Running VMFS Checker version 0.9 in check mode
Initializing LVM metadata, Basic Checks will be done
         ERROR: Missing LVM Magic. Disk doesn't have valid LVM Device
         ERROR: Failed to Initialize LVM Metadata
   VOMA failed to check device : Not a Logical Volume

Total Errors Found:           0

With this we can see the LUN.

"after the reboot" - which reboot? What caused this condition in the first place? Seems like the filesystem on that device has been destroyed; the errors in the vmkernel log are just for the CD-ROM drive. — Shane Madden, Aug 01 '14 at 16:27
After rebooting the esx servers. We had to reboot them for maintenance. — baaron, Aug 01 '14 at 22:03

Please Refer to the following KB article from vmware. You probably have a stale lock on it.

vmkfstools -B /vmfs/devices/disks/naa.00000000000000000000000000:1

where naa.00000000000000000000000000:1 is replaced with the LUN NAA ID and partition to be checked. Note the ":1"

FYI: naa is not always the prefix. Mine are a fiber lun that starts with eui.
