RE: Tape backup issues after upgrade to 7.0.4 - toasters

      Shouldn't matter whether backing up QTrees or Volumes for this issue.
It appears that the request to mount a tape drive is timing out.
Backing up volumes is supposed to be faster than QTrees.

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
