I'll verify with my docs at work tomorrow, but I believe that 'random' makes it work like a true changer and 'sequential' behaves more like a stacker. Amanda has changer scripts that can be configured to find and use the correct tape(s) for each run. Mine shows three devices, one is the changer mechanism (the scsi driver sees it as a Qualstar) and the other two are the two tape drives in the unit (the scsi driver shows those two as Sony). Look in your boot messages to see if you have something similar (its been many years since I've touched HPUX, someone else will have to chime in on how to probe scsi devices on HPUX). You may also need the mtx drivers to control the changer (http://mtx.sourceforge.net/) if HPUX doesn't have enough builtin support. Make sure you can load/unload/move tapes from the command line before you even bother with the amanda changer scripts or you will waste a lot of time and get very confused. > Also, if a dump image is bigger than one physical tape, I don't > think amanda would work.

With the released version that is true, although you can use GNU tar and backup subdirectories that are each smaller than a tape. I believe tape-spanning is in development but I don't know an ETA. I personally prefer tar over dump, but many on this list have the opposite opinion.
