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.

(CLEANED=0) Information 01-10-2005 00:14:48 Begin cleaning database.

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
I would doubt that very much. Veritas NetBackup has used version 4 since at least 5.0. Most backup applications negotiate the version of NDMP correclty. Granted, older versions of some software (like NetBackup 4.5) did not and you had to set the version manually.
While I worked at NTAP, NBU was the only product I had to do that with.
Honestly though, there is a bug in ONTAP tape storage code that is exactly this problem. Dump works fine until you have to span tapes.
This fix, I was told, will not be in ONTAP until 7.0.2.
A quick look at the bug fixes do not show it as being fixed in 7.0.1.1P2
