I've not looked at the code, but if chg-scsi detects it via the status request it might show up in the mtx status output. If so, then it would be 'easy' :) to add that capability to chg-zd-mtx. It is too bad that neither ch-zd-mtx nore chg-scsi support RAIT as that is the way I would like to eventially go. Amanda does support a form of it own RAIT. But I don't think it is well tested as few people report trying or using it.

Again, any configuration suggestions will be greatly dumpcycle 7 tapecycle something greater than 14 runspercycle 5 or 6 or 7 Amdump can be run anytime by hand specifying the hosts and DLEs. You can also force, with amadmin, a level 0 of any DLEs for the next amdump run. A separate config could be setup sharing many of the control files (disklist, indexes, curinfo, tapelist, changer.conf, ...) but with record set to no and a dumpcycle of 0 (always level 0). Then you could run amdump for that config and leave the standard one alone. Be careful they don't try to run at the same time. -- Jon H.

please check your config and use a config file for chg-scsi
I am STILL trying to get amanda set up to run with an adic Scalar 458 changer with three DLT4000 drives. After spending far too many hours reading and re-reading the docs and sample config files. I took a shot at building a configuration. I decided to try to label a tape. After that failed miserably, I decided to take a step back and just try to get chg-scsi to work. I started with the chg-scsi-linux.conf then I tried using the -genconf option. The best I can get out of either of them is please check your config and use a config file for chg-scsi. The contents of changer.conf file (without comments) are: number_configs 1 emubarcode 0 havebarcode1 debuglevel 9:0 eject 1 sleep150 changerdev /dev/sg6 config 0 cleancart 46 cleanmax 20 drivenum 0 dev /dev/nrst0 scsitapedev /dev/sg7 startuse 0 enduse35 statfile /etc/amanda/tape0-slot cleanfile /etc/amanda/tape0-clean usagecount /etc/amanda/tape0-totaltime tapestatus /etc/amanda/tape0-tapestatus labelfile /etc/amanda/labelfile --Richard
