Backup of VM's failing after moving them to a new LUN
Posted on 2011-03-01
Using Backup Exec 12.5 I can no longer backup my VM's using the Transport mode of 'SAN'. But when I ran a test backup of a VM using the NBD mode it completed successfully but took awhile. Here's what has changed:
1. I had 2 LUNS (each one was 850Gig - labelled LUN 1 & LUN 2)
2. We added a 3rd LUN (1.8TB - labelled LUN 3)
3. I moved all my VM's to LUN 3 so that I could re-configure LUNS 1 & 2, blow them away and make it one big LUN - now labelled LUN 0)
4. So now I have 2 LUNs - labelled LUN 0 & 3
The 2 LUNs are both visible in my 2 ESX 4.0 hosts and I have VM's residing on both of them.
The error I get in Backup Exec is:
Final error: 0xe000954c - An error occurred while running the VMware 'vcbMounter' command to back up a virtual machine. See the job log for details.
'V-79-57344-38220 - Backup of the virtual machine 'servername' failed. VMware VCB framework reported the following error'
That's all it gives me. No following error. I've researched the link and every connecting link for Symantec. I've restarted the vcbmounter service hoping it would re-scan the LUN's.
Is there something else I would need to refresh that's causing this?
