We had the same issue with timeouts using Legato under OnTap 6.something.
I'm almost sure our storage group addressed this by switching to a Qtree backup. Rather than backing up the entire volume, they now back up qtrees. I have to inform them if I add or remove a qtree now.

Shouldn't hurt anything having a longer timeout.  For the ones that are not currently timing out, there should be no impact to them as they would report back to NetBackup just like they do now.

This is something I have discussed with our Netbackup experts, they are a little reluctant to do this as it is a global setting and would increase timeouts across all backuos NDMP and non NDMP.

Perhaps a timing isssue.  Anyway to increase the timeout for NetBackup
to wait on a reply from the drives?

Hi,

I am working with a R200 that has recently been upgraded from 6.5.5 to
7.0.4. Before the upgrades our NDMP tape backups were excecuting fine.

We are now sporadically getting the following error via Netbackup:

UNX-F-FAIL NetBackup policy NDMP_WIN2KBAKUP_NEW - jobID 61716  - failed
on lonffp06-bsn. status 52. ( 52 timed out waiting for media manager to
mount volume ) See BOA-NBU-14. Vault or synthetic backup failed.  -
Please investigate

lonffp06-bsn - is the backup subnet connection from the R200 (lonffp06).

The toaster is connected to six tape drives, StorageTek 9940B .

I have replaced the HBA, and fibre connections as I felt it could be
hardware issue. But the errors are still persistent.

Netapps support cannot come up with an answer for this one, I was
wondering if anyone had any idea's?

Many Thanks,

Niren
