Can't mount datastore snapshot without formatting it

[haba7]

Hi,

We have a LUN on EMC VNX acting as VMFS datastore and I should mount one of its snapshots as a datastore to ESXi 5.1 host. When I try to mount it, VMFS Label is empty, which means that ESXi does not recognize it as a VMFS datastore:

However, the LUN snapshot has VMFS and its GPT table:

~ # partedUtil getptbl /vmfs/devices/disks/naa.60060160a3703d0089b4e5084f1fe711

gpt

534698 255 63 8589934592

1 2048 8589934558 AA31E02A400F11DB9590000C2911D1B8 vmfs 0

How can I mount it?

Best regards,

It might be an issue with LUN snapshot replication, so try to replicate the snapshot again and give a try.

The array supports writable snapshots and I haven't replicated the snapshot but attached it directly to a mount point. This is 4 TB datastore with 3 TB of data and replicating it wouldn't be feasible.

It might be an issue with snapshot you are trying to present. if you have any other snapshot, give a shot with them.
