Also check the NDMP version level that Arcserve is set at.  Most backup software, with exception of Syncsort Backup Express v2.2.x, will only work up to NDMP v3.  NetApp DOT v6.4 and above default to v4.  Basically, when first tape is done filer is sending v4 status command to Arcserve stating EOT and request new tape mount, v3 backup software doesn't understand command and plays dumb, eventually filer will time out waiting for new tape and responds with a tape failure message.

You need to change ndmp setting of filer to NDMP maxversion level of 3.

>ndmpd version 3

Use command without version number to display current setting.
 
Have fun,

Whaqt version of ONTAP are you running?
I think you are hitting a bug in the NDMP code on ontap.

Are you running 7.x? if so, upgrade to 7.0.1.1P2 ASAP and see if your problem goes away. I think the bug was fixed in that patch release (or maybe 7.0.1.1P1).
