I was setting up an NDMP accelerator node today to back up a new VNX and came across this error message when trying to backup a test volume for the first time:
Errors and Exceptions

[snapup-/NDMP_Test] Backup for target /NDMP_Test had errors. (Log #2)
After I double checked that everything was setup correctly on both the NDMP Accelerator node and on the VNX, I decided to simply create a manual snapshot on the VNX first and see if I would run into trouble. The snapshot completed without an issue. I went ahead and just reran the backup and it ran successfully. I guess the VNX just needed a little manual intervention.
