Is /vol/vol0 on your machine a snapmirror destination? If so try backing up an existing snapshot as ndmpd will not be able to create a snapshot for dump on a snapmirrored volume. The path that I use in the Backup Policy Mgmt interface under the policy of my choice I simply change the entry from "/vol/vol2" to "/vol/vol2/.snapshot/hourly.0" and bada-bing it worked.
If it is not snapmirrored then another test to try would be to run a manual dump of /vol/vol0 and send the output to null:
dump 0f null /vol/vol0
The output of that command will be useful for NetApp support folks.

Anyone else having difficulty backing up /vol/vol0 with Veritas after upgrading to DOT 6.1.1? We get the following error message:
0997254443 1 4 8 claxton 750651 750651 0 fuelcell bptm WRN - Cannot backup filepath /vol/vol0, NDMP_HALT_INTERNAL_ERROR occurred (path may not exist), skipping
We also found this upon deeper investigation:

Here's the interesting rub: other volumes on that machine (/vol/root and /vol/vol1) backup just fine. /vol/vol0 won't backup to a local tape drive, or remote via NDMP 3-way. This has manifested itself on more than one machine, but not all 6.1.1 filers. Really strange.
We're submitting a case to NetApp, but just wondering if we're the only ones seeing this problem.

Thanks to Mike for identifying this as bug #45768. This one's a killer for anyone considering an upgrade to 6.x.
