We recently had a hard disk failure in an esx 4i free host. Long story, but for some reason the failure of a single disk managed to take out the entire raid 5 volume (so much for resilience!)
(There is no san on this system - all local disks on a sas array controller)
We replaced the kaput hard disk, rebooted the host.
Health check shows all the hardware is fine.
Rescanning the controllers & vmfs shows only the vmfs volume on the mirrored disks (unaffected - vmhba1:C0:T0:L0) not on the raid 5 (vmhba1:C0:T0:L1)
If i look at the disk device in storage, i can see the vmfs volume listed
Running esxcfg-volume -l gives me no results
looking in /vmfs/volumes, i see:
/vmfs/volumes # ls
ls: ./4bc4a1b9-c664892e-03ad-0025b3ded4d2: No such device or address

Using "Add storage" tells me it's going to over-write everything and lose all data. There's a VM on that volume that i'd very much like to recover if at all possible.
Performing a rescan shows some information in the messages file (see attachment)
I've tried all the tricks I know, and google has either come up empty or i'm being swamped by issues talking about snapshot disks - which as far as i can tell.
Hope one of you good people on here can assist.
