UNCLASSIFIED 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, Don

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).

Hi all,
Anyone out there that can help with the following:
We have a R200 Nearstore with a Storagetek L80 library attached trough FC.
We use Brightstor Arcserve 11.1 SP1 (latest patches) to backup a volume on the filer.
All seems to go fine, until the second tape is requested. In the Arcserve log it says:
E8535 01-10-2005 00:15:04 154 1 Failed to receive data from the client agent. (ADDRESS=xxx.xxx.xxx.xxx (xxxxxxx), EC=9, COMMAND=0) Information 01-10-2005 00:15:01 154 1 Resume Backup Operation. Information 01-10-2005 00:15:01 154 1 Format FRIDAY [S/N:, ID:1541, Seq:1] as FRIDAY [S/N:, ID:9F36, Seq:2]. Information 01-10-2005 00:14:48 End cleaning database. (CLEANED=0) Information 01-10-2005 00:14:48 Begin cleaning database. Information 01-10-2005 00:14:01 154 1 Next media FRIDAY, ID 9F36, sequence #2 Information 30-09-2005 21:01:07 154 1 Backup Session 1 on Media FRIDAY Information 30-09-2005 21:01:07 154 1 Source Directory: vol\data.snapshot\hourly.0
After this the backup job obviously fails.
We have tried all options given by arcserve but without any success. Also we attached the library using direct attached SCSI but no success. All the configuration options are checked and seem oke. Also the NDMP log on the filer shows no errors.
Regards to all toaster fans,
Patrick
