At the moment we run 5.3.4R3P2 and have only the problem with with DOWNING Drives (irregular, about 1-2 times a week).
It looks like netapp has problems with Ontap Releases gretaer than 5.3.4R2. The last 3 months we used Ontap 5.3.4R2 without any problems.
The switch to Ontap 5.3.5P2 (note that netapp and veritas promised us it will work) was a disaster! After switching to the new version everything looked fine. But after about 5 hours the drives went down and setting them up was impossible. Error Message: Apr 29 00:49:17 viws111 avrd[17817]: fatal error on device 3 (ndmp_connect_open_and_auth), ndmp_result = -5, DOWN'ing it. (messages on Netbackup Master)
After that and some calls by veritas and netapp we downgraded to Ontap 5.3.4R3P2 and only(!) have the downing drives problem.
Netapp then recommended us to switch to Ontap 5.3.5R2P1 and promised us to have that NDMP Bug fixed. By our next shutdown we would have switched to that version of Ontap. But now it looks like we will stay on 5.3.4x so long as we can afford it.
I hope Netapp and Veritas will improve their quality with better certifications in the near future and tell us facts, not feelings.

Yeah- we too are having all kinds of backup related problems with the one filer we have upgraded to 5.3.5R2P1. In our case, we can't back up the machine at all.
Aaarrgh, this one really hurts. Not to mention the fact that NetApp had us upgrade to this version partially because of ECC errors we were getting. This is a brandy new F760 to boot.
I'm not looking forward to begging for the downtime needed to fix this one. It'll be like...
Me: "Uh, hi, um- we need some dowwntime one of the Filers." Them: "Why?" Me: "Ah- because we can't back it up suddenly." Them: "What!?- How long has THIS been going on?" Me: "Since we upgraded the OS last Friday." Them: "You mean that we could lose data from as far back as Friday?" Me: "Unfortunately. Yes."
... Well you all get the picture. I guess I'm just venting because not being able to backup a filer is a PRETTY BIG BUG!

We upgraded out filers to NetApp Release 5.3.4R3P2 this weekend.
Since then, NBU 3.2 keeps downing the tape drives on several, but not all of the filers (3 of 9). This seems to happen before, during and after backups.
Has anyone else seen this? Thanks!!
we saw this on previous versions of NBU, 3.1.*, the work around was
really
lame. cron executed a script which did something like: vmoprcmd -up

for
each drive.
Hi there!
We also have the same problem with this release of Ontap and Netbackup v3.2. According to Netapp the cause of this problem is a faulty Java Class (Garbage collection) which NDMP uses. This should also be the reason for the problems with Ontap 5.3.5xxx, where the problem got critical and backup stopped working.
Netapp recommended us to switch to Ontap 5.3.5R2P1, where the NDMP-BUG is (hopefully) fixed.
