Data Loss - Recovery Possible?

After an unfortunate series of events I have a VM residing on a Celerra NFS mount that is not accessible.  Stupidly, I was only using snapshots to "protect" this VM.  I am now simply trying to find an answer to the question, is data recovery possible?

The Celerra experienced a sudden power outage and there were a number of hardware component failures upon powering the unit back on - one SPS and one DM had to be replaced.  Our third-party support was able to get all the LUNs back online, but all of the file systems were corrupted - some more so than others.

The VM in question was shut down at the time of the power outage and resided on a set of disks that stored nothing else.  The vmdk file itself is corrupt; I am unable to attach it to another VM nor can I download it via the datastore browser or scp.

If you have support from EMC, I would highly recommend opening an SR in this scenario.  Since you mention third-party support, I don't believe that you do.

Your next option might be to contact your local EMC Sales Team and request a quote for Off-Contract Support.  EMC can provide time-and-materials support on a fee basis.  If the data is of significant business value, this might be preferable to your last option.

Finally, you can attempt to fix the filesystems yourself.  If you su to root on the control station, you could try to use /nas/sbin/root_nas_fsck and attempt to repair the filesystem containing this VM.  It's a long shot and might even leave you worse-off than you are today.

Let us know if that helps!
