For what it may be worth, Derrick, I have a Sun StorEdge jukebox attached to an Enterprise class Solaris system. While mtx itself worked, I never got the chg-zd-mtx script to work. I had to do things like hard-code variables just to even get it to run but I never got it to perform any significant functions. I inhereted the installation and found out that chg-scsi was never tried, but lo and behold, I spent a little time tweaking it, it worked well, and have used it ever since. It really is a great little program. The only functionality that does not work for me right now is the barcode stuff but Thomas Hepper has been working with me to make that work. BTW, I use 2.4.3b2. The StorEdge is a 30-slot jukebox with two DLT IV tape drives. Any pointers whatsoever would be greatly appreciated, as I've been beating my head against this for over a month and have made very little progress. Good luck. If I hadn't discovered chg-scsi would do the job, I would have tried writing my own perl script. Lots of people use chg-zd-mtx, though, which always made me feel worse! :^P - - - -- Eric Trager CMAG, DCB, CIT, NIH [EMAIL PROTECTED]

With this tape drive running alone on the SCSI bus from an adaptec 2944,

Re: ADIC / Dell Powervault 120T changer problems under Linux (Pt 2)
Jim, I have this changer working with RedHat 7.2 using the 2.4.2p2 chg-zd-mtx script. The trick to getting it working is getting the configuration file for chg-zd-mtx right. Make sure all the variables mentioned in the script are defined. In my case I have (in /etc/amanda/CONFIG/chg-zd-mtx.conf, replace CONFIG with your configuration name): Are you using the Amanda RPMs supplied with Red Hat 7.2, or did you compile 2.4.2p2 from source? Since I posted my previous message asking for help, I have managed to get Amanda working well with the changer, by compiling from source. I would like to switch back to the RPM version if it will work, though, since I find it's much easier to manage the system using RPM and up2date than it is with source tarballs. Thanks for your help, Derrick Miller

I am using a different changer script supplied by Chris Pascoe and once upon a time posted to this list (in a slightly earlier version). I strongly recommend using the chg-zd-mtx from the current CVS now as recommended by John R. Jackson.

Re: ADIC / Dell Powervault 120T changer problems under Linux (Pt 2)
John Jackson pointed me to a new chg-zd-mtx script ... but it also barfs, complaining about /usr/lib/amanda/chg-zd-mtx: @AMANDA_TMPDIR@/chg-zd-mtx.status.30913: No such file or directory ... I also said: Save your current chg-zd-mtx.sh.in and replace it with this one, then rerun ./configure (or config.status) and re-install. Did you do this? If the installed chg-zd-mtx still has a bunch of @XXX@ things in it, it implies you didn't rerun ./configure (which substitutes them while converting chg-zd-mtx.sh.in to chg-zd-mtx.sh). Then you need to rerun make and make install to finish the creation and installation of the script. You cannot just take the script as I presented it and drop it into your executable area.
