How to stop NB from downing drives?

[MattS]

I have VTL's so i dont want netbackup to down drives after x number of failures.  Anyone know where this setting is located?  Or if it's even configurable?

NB 7.0.1 - OREL4 master

Settings exist in EMM database for each media server.

Check as follows:  nbemmcmd -listsettings -machinename <media-server>

Look for:

DRIVE_ERROR_THRESHOLD="2"
MEDIA_ERROR_THRESHOLD="2"
TIME_WINDOW="12"

change with:
  nbemmcmd -changesetting -DRIVE_ERROR_THRESHOLD <number> -machinename <media-server>
nbemmcmd -changesetting -TIME_WINDOW <number> -machinename <media-server>

I suggest you increase the error threshold and reduce the time window.

See NetBackup Commands http://www.symantec.com/docs/TECH127047 for full details.

Changing the values to effictively disable NBU Downing the drives might just mask possible hardware problems - VTL's DO experience hardware problems from time to time!

Thanks Marianne!  I was searching the Commands pdf but didnt really know what to search for :P...

I agree setting it to never disable drives isnt a good idea, but it's got to be higher than my retry count!

Thanks again,

Matt
