Re: [Veritas-bu] ACS status = 29
Good Evening, Do you have the tape drive cleaning set for library control or netbackup control. We found we had problems when netbackup was set to do the cleaning. We found a technote that for the stk (now sun) ACS controlled libraries one must let the library control the cleaning and not netbackup. len From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of rusty.ma...@sungard.com Sent: Friday, November 13, 2009 4:49 PM To: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU Cc: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU; veritas-bu-boun...@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] ACS status = 29 I'm seeing the same issue at one site and I'm curious if your drive had a stuck tape, or for some other reason couldn't move the tape from the drive to the home cell?

Re: [Veritas-bu] ACS status = 29
Sometimes the problem can be related to the default unload timeout value, which i guess its 5 minutes. I got this problem with T10K drives, and when we changed this timeout to a higher value, it worked. I dont remember exactly the parameter, but you can look for it in hosts - media servers - properties - timeouts . regards, Nick - original message - Subject:Re: [Veritas-bu] ACS status = 29 From: "Marianne Van Den Berg" Date: 11/13/2009 6:39 PM You need to determine if it's one or all media servers having a problem with dismounts. The most common cause of unload failures is device mapping mismatch (when ACS address e.g. 0,0,10,0 does not map to the correct /dev/rmt/xcbn device name). If logging is increased on ACSLS side, you will be able to see all mount/dismount requests in acsss_stats.log. If you have VERBOSE entry in vm.conf on all media servers, you will be able to see the NBU part of Media Manager comms as well in /var/adm/messages.
