Hi all
We've recently upgraded from NetWorker 7.5.1 to 7.6.3 (Windows 2003 R2
Standard SP2 32-bit). As our VCB backup proxy was also the backup server
itself, we've naturally had to switch from the (working) VCB backup method
to the new (awful!) VADP backup method.
First of all, we were on version 4.0.0 of vSphere which _should_ have been
supported, but it turns out that the minimum spec appears to be 4.0.0
Release 2 - annoying! Fortunately, that got upgraded a week later, albeit
on a new hypervisor (Windows 2008 R2 64-bit).
Some of the VADP backups work great, however we have a dozen or so failing with:
* vm_hostname:*FULL* Could not mount required number of volumes. Exiting.
* vm_hostname:*FULL* The VADP proxy and the VM client are possible clones of
each other or derived from the same parent. Please try by setting the
transport mode as nbd.
I've come across this
http://solutions.emc.com/EMCSolutionView.asp?id=esg123567&usertype=C but our
VMware admins can't see any issues with the disk configurations.
I've also added the application information value of VADP_TRANSPORT_MODE=nbd
in the client resource for the particular VM, but it seems to ignore this
setting as the save command output (please see attached) shows:
Using 'san' as the transport mode for Hard disk 1.
The clients that are failing are mainly Windows, both 2003 and 2008 and both
32- and 64-bit, but there's also a couple of Linux as well. I can't see any
commonalities with the failing backups.
Has anyone experienced this issue before?
Thanks
Brian
