PROBLEM:

Linux/Windows servers , all VMs backed up with VMware snapshot API,  would not boot up after they were restored using the default restore options.

SOLUTION:

Changed the restore transport type to NBD and all the restores worked fine.

That's all very well Sajeev but if your VLAN infrastructure does not allow for the use of nbd as a transport type - what are the alternatives? Is there going to be an EEB appearing soon? I have exactly this problem on NB 7.5.0.3.

Sajeev - I sent you a message but I thought I should reproduce it here in case it helps others .

Hi Sajeev - thanks for replying. We have a small number of Shared Storage Media Servers. The Master server is AIX 6.1 as are another 4. We also have a VMware infrastructure and a VMware media server (Windows Server 2008R2) handling the backups via the VCentre. We have recently upgraded to NB 7.5.0.3. We experienced the fault with VMware backups as described in http://www.symantec.com/business/support/index?page=content&id=TECH191198 , applied the fix and backups via SAN then worked as before (we upgraded from 7.5.0.1). Restores via SAN also worked. However, when attempting to boot the restored container (Windows & Linux) we get the message "No Operating System Found" as described in

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2021483.

VMware details :-

VMware vCentre version: 5.0.0, 623373 (vsphere 5.0 update1)

VMware hosts version:  ESXi 5.0.0, 623860  (vsphere 5.0 update1)

Datastore Version: VMFS-5

 

Our LAN infrastructure does not allow us to use NBD but I am going to try and see if I can get the appropriate ports opened to see if the restored container will boot.

Having messed around with our network I can now backup and restore via LAN OK. The good news is that the restored VM does indeed boot so I can confirm that your workaround does work in my case as well.

It is however only a workaround and I will now log this with Symantec - assuming the MySupport website is up today.

the other option is to use the OS install CD/DVD and repair the boot partition. Works for Windows and Linux.

Make sure the VM Disk on Windows backup host is online. By default the zoned disk will be offline on Windows backup host and the backup works fine and the restores required the disks online.
