    It may well be that your volume is going up and down regularly

    Run an All Log Entries report from the NBU Admin Console for a 24 period (or at least one covering the alert time)

    This will tell you if it is really going up and down (and they often do but aren't noticed unless you actually run a report)

    If they are then my advice is to add the DPS timeout file to your Master Server and the appliance

    It is a flat file, located at /usr/openv/netbackup/db/config/ (or windows equivalent) and is named

    DPS_PROXYDEFAULTRECVTMO

    You may well find that it already exists - but check the value in the file - 800 i have found to work best - it oftern uses 3600 which is too high - 800 works nicely

    If you have to create or change the file then you need a NetBackup re-start to register it

    Hope this helps

If Mark's advice shows that it's only going "down" for one or two minutes it may be something I've seen with our 5220's running 2.5.3.  The Master queries each Appliance once a minute and if the Appliance is too busy doing other things, that query fails and it gets marked "down".  This especially seems to happen right at the end of the twice-a-day transaction log processing.

 

What I had to do to decrease the false alarms was to change the Media Server Connect timeout in the properties of the Master server (and Appliance Media Servers) to 240 seconds.  That seems to let it tollerate the occational loss of response to the regular "are you still there?" queries.
