Our setup: TSM 5.4.1.2 Server on Linux, a 19TB disk pool dedicated to the management class for the NAS node. The disk pool is largely made up of 1.8TB volumes on a RAID5, the maxfilesize is set to 'nolimit', highmig=100, lowmig=99. The NAS is a BlueArc, according to the trace: NAS Vendorname: BlueArc Corp. Productname: Silicon Server NDMP. Revisionnumber: 6.1. Hosttype: BOS. Versionnumber: 6.1.
The filesystem in question: fsName=/__VOLUME__/cifpilot1, fsType=WFS, fsId=2, fsCap=10Tb, fsOcc=8650Gb When I perform a backup of that filesystem (backup node XXXXXXXXXXXXX.umich.edu /__VOLUME__/cifpilot1 toc=yes mode=diff), rather than go to the empty disk pool, it immediately goes to tape. This is causing a problem because the job is getting preempted when the scheduled migrations occur on the other servers at 7am. Other smaller filesystems (0.4 and 5TB, respectively) backup to disk just fine. I've moved the backup as early as I could to try and get it to complete before migrations, but that's not working anymore. I need to figure out why this backup is going to tape rather than to disk. Anybody have any ideas? - Cameron Hanover [email protected] "Necessity is the plea for every infringement of human freedom.
