[Veritas-bu] NBU 6.5 Snapshot Client problem

Setup: NBU 6.5.2 on Solaris 10/sparc, Snapshot Client option, Veritas Storage Foundation 5.0 MP1 RP4. The client is the master server itself ("bkp-master02").

I'm trying to do a "space-optimized instant snapshot" backup as described on page 113 of the "Veritas NetBackup Snapshot Client Administrator's Guide Release 6.5". It says that if a cache object named NBU_CACHE exists, it will perform a space-optimized snapshot automatically.

The backup is failing with generic error 156 ("This status code indicates a snapshot-backup related error regarding Windows Open File Backup or Snapshot Client."). I have enabled snapshot backups for the policy, with 'vxvm' as the snapshot method. The backup policy works with snapshots turned off, though it only backs up the symlink pointing to the volume raw device.

The errors from 'bperror' are:

The errors from the 'bpfis' log are:

Here's what the VX disk group looks like:

Any ideas?
