VMware 5 missing datastore

Hi,

I have a server I run at home that uses ESXi 5.1. I had a power outage the other night and when the server came back online the secondary HDD which contains a lot of my labs no longer shows as a datastore. I can see the physical disk and when I select to re-scan it doesn't find it.

I can see in the CLI that the disk has a partition and I am able to create a new partition (I haven't as I don't want to overwrite).

How can I recover the partition?

Cheers

They will scan any partition, detecting VMFS, and recover VMDK files.

once the VMFS datastore is corrupted, it's very difficult to recover.

if you click Add Storage, does it come up as blank, and what to re-create a new datastore ?

try

 esxcfg-volume -l

at the console or remotely via SSH
