We have had a tape changer running with amanda for a while but it was just being used as the a single drive and the data is starting to exceed the size of the tape.(DLT40 - 80G compressed)
I'm starting to look into utilizing the functionality of the changer. I've looked at the docs and have the impression that all I have to do is specify the chg-scsi in the amanda.conf and set-up the chg-scsi.conf. Here are examples of the part of amanda.conf and chg-scsi.conf. amanda.conf: tpchanger "chg-scsi" # the tape-changer glue script tapedev "0" # the no-rewind tape device to be used changerfile "/opt/amanda/etc/amanda/homes/chg-scsi.conf" chg-scsi.conf: number_configs 1 eject 0 sleep 60 cleanmax 10 changerdev /dev/rsst4 # # Next comes the data for drive 0 # config 0 drivenum 0 dev /dev/rmt/0bn startuse 0 enduse 4 statfile /opt/amanda/etc/amanda/homes/tape0-slot cleancart 5 cleanfile /opt/amanda/etc/amanda/homes/tape0-clean agecount /opt/amanda/etc/amanda/homes/totaltimef tapestatus /opt/amanda/etc/amanda/homes/tape0-status I think I understand the contents of this file but I don't know what to put for the changerdev file. Up till now I've been using /dev/rmt/0 for backing up to a single tape so how do I find what this value should be for my changer.(/dev/rsst4 does not exist) Also when I've got the changer working how do the tape numbers work? If a night's backup tape starts on homes02 and spreads 2 tapes will amanda understand it's spread over homes02 and homes03? If so how does this affect restores? David Flood Systems Administrator
