There are two possible places for the potential problem:
1. Master server is unable to connect to the media server to cancel related processes.
2. Media server is unable to stop running process because it might inlove unresponsive tape drive or something like this.
If I were you I would run test policy to some disk based STU on different media servers to exclude reasons like this But it could be a simple bug.
Mike, I think there's two things going on:
1) I haven't had the chance yet to upgrade the Appliances from 188.8.131.52 to 7.7.3
2) The increased security in 7.7.3 that requires everything to be 100% correct or the command fails
I'll see if it continues to happen when I finally bite the bullet and perform the 8+ hour upgrade of each of my Appliances.
Yes, 2.7.x upgrade is quite painful. NBU now uses certificates even if you don't use NBAC (I was surprised). I do believe in backward compatibility but the certificates can add extra problems. For example 7.7.3 upgrade ruined our customer's NBAC configuration and the only thing Veritas could adviced was "Uninstall and install NABC again" :)
Ok, a little more testing has pretty much confirmed it's the version missmatch.
If I run a job only involving my 7.7.3 boxes, it cancels right away.
If the job involves any of the 184.108.40.206 boxes, they won't cancel. And, this is the really ugly part, it also means that SLP Window closures no longer shut down SLPs.
Yes, I've done the "push the certs out and restart" commands. So the basic problem is that, with 7.7.3, there are a TON of undocumented changes that make it incompatible with any previous version.
I'm just wondering what kind of <deleted> will happen when I do finally upgrade the 7.x boxes but not the clients (don't ask, some not supported, some too political to upgrade)...I hope that basic file backups still work...
