We are testing Netbackup for VMware 7.5 .
Upon restoring full VMs the restored VMDKs are unformatted, making the VM unusable. The VMDK is there but it's blank, what might be causing this?
Restore Method: SAN, alternate location, original disk format, original VM hardware level.
Thanks

Ok - just a guess but are your VMWare backup hosts (Media Servers) Windows 2008 by any chance?
If so go to disk management and you will see the LUNS for the ESX Datastores show as off line.
You can back up in this state but not restore (even though it says it was successful)
Right click the far left of the disk and select online (DO NOT INITIALIZE OR ANYTHING ELSE!!!)
You restore should them work
As a test restore one via the LAN as you are now - that should be slow but successful
Hope this helps

Mark, thanks,
Yes the Media Server is 2008 and I have noticed before testing that the disks showed OFFLINE (I am using native MPIO btw). I did bring them online before the test, but I'll try to use NBD as you suggest and keep you posted.
Thanks

Restores through NBD work as expected. The media server is using MPIO to access the LUNs. The disks show as Online and Offline (the redundant path to device). Now I need to find a workaround. Is anyone using something other than native MPIO (Powerpath or similar) ?
Thanks

MPIO software is usually tied to yoru SAN itself other than native Windows 2008 MPIO
Can you change the MPIO policy it ises so that both are online?
Right click the disk and select Properties - should have a MPIO section for the policy being used (maybe weighted paths will work?)
Check it all out first of course - look after those disks!!

I'll try that and post the results. No worries Mark, I set up a test environment for this
