Some months ago this list helped me fix my chg-zd-mtx script to get rid of amtape 'offline' errors. Probably amtape commands don't work for you either and if you get amtape to work then amcheck will also work. I've attached my chg-zd-mtx script. Note that it contains debugging commands, so you'll get /tmp/amanda/chg-zd-mtx.* logs that will contain lots of info. Also, check that your changer.conf file does not contain comments, because it does not understand comments. I think one of the mistakes I made was to have "commented out" lines that were are actually being processed. If you have comments, you need to remove them. Here's my changer.conf file: firstslot=1 lastslot=7 OFFLINE_BEFORE_UNLOAD=1 AUTOCLEAN=0 havereader=0 > Now, I try to configure Amanda. I have the following output from the > amcheck command: > > [root@lmcpc111335 /root]# su amanda -c "amcheck DailySet1" Maybe try to test the EZ17 with amtape instead of amcheck, eg: 'amtape DailySet1 current' or 'amtape DailySet1 slot next' or 'amtape DailySet1 show' Pam <<<-------------- chg-zd-mtx ------------------>>> #!/bin/sh # # Exit Status: # 0 Alles Ok # 1 Illegal Request # 2 Fatal Error # # Contributed by Eric DOUTRELEAU <[EMAIL PROTECTED]> # This is supposed to work with Zubkoff/Dandelion version of mtx # # Modified by Joe Rhett <[EMAIL PROTECTED]> # to work with MTX 1.2.9 by Eric Lee Green http://mtx.sourceforge.net # # Modified by Jason Hollinden <[EMAIL PROTECTED]> on 13-Feb-2001 # to work with MTX 1.2.10, >9 slots, has barcode support, and works with # multiple configs at once. # NOTE: Only tested the 2 additions with an ADIC Scalar 100. # All my additions have a '#### Comment' close by. ################################################################################ # NOTE: all variables are now placed in a 'changerfile'.conf in your # amanda config directory, where 'changerfile' is what's set in # amanda.conf.
