We have an HP Proliant DL380 G4 cluster with MSA500 G2 running NW6 SP5.
We are running Arcserve 11.1. The backup jobs run, and data are
merged to the database. However, we are unable to run a restore. The
error we receive is:

Fail to Write DataSet
Error fffdffb1

The server has TSAFS.NLM version 6.51, 6-8-05.

Any suggestions on how to make the restore jobs successful?
