Hi,
1.) i hope you only have one of the lines (A) and (B) in your
amanda.conf at the same time, don't you?
2.) line (A) is the correct one for chg-scsi
3.) remove each and every comment from your chg-scsi.conf file, they
sometimes confuse chg-scsi.
hope it helps....
Christoph
Item 3.) above is something I've never had to do here. If there ever was a problem, its long since scrolled out of my wet ram history. Currently running release 2.4.4p1-20030715.
i had problems with comments in it, and none without them.....

thanks Jay, makes great sense. so the tpchanger envirornment is attemping to call the C program in the libexec directory
NOW my only problem IS: tpchanger should call the C program (chg-scsi) in my case... where does the CONFIG (chg-scsi.conf) get called from, or it doesnt need to be?
so this error(s) Amanda Tape Server Host Check ----------------------------- (1)amcheck-server: could not get changer info: could not read result from "/usr/local/etc/amanda/DailyBackup/chg-scsi.conf"
or now: (2)amcheck-server: could not get changer info: check your config and use a config file for chg-scsi ..amanda.conf snippet: ..snip.. notes: IF THIS line (A) is commented/# out, I get errror 1 (otherwise I get error B (A) tpchanger "chg-scsi" # the tape-changer glue script (B) tpchanger "/usr/local/etc/amanda/DailyBackup/chg-scsi.conf" tapedev "/dev/rmt/0n" # the no-rewind tape device to be used changerfile "/usr/local/etc/amanda/DailyBackup/chg-scsi.conf" changerdev "/dev/scsi/changer/c1t0d0"

OK. Jay makes sense here:
1) Jay says: I have choices: chg-scsi or chg-zd-mtx.
but I have a third config file in the distribution called
chg-scsi-solaris.conf
The files: example/chg-scsi-{hpux,linux,solaris}.conf are just example chg-scsi config files with OS-specific "typical" device names inserted; they do not represent different tpchanger executables. You'll not find libexec/chg-scsi-solaris, right?
The X80 has 80 slots for tapes. (elements) Tape Drive 1 isI'm sure there is an excellent and highly amusing reason for that. :-)
element 451, 2 is 452, 3 is 453,
and the cleaning cartridge lives in slot 0
and element 401-405 are the only way to put tapes in/out of unit!
You're apparently intended to initially populate the library through the little five-tape import/export hole, and then seldom/never touch the tapes again. Unless you were planning on rotating tapes off-site, that's actually a perfectly good way to go, I guess.
Amanda won't do anything with the import/export slots, you'll deal with that outside amanda somewhere.
With mtx, you would fill the import/export slots, then have a script do something like:
mtx transfer 401 1 mtx transfer 402 2 mtx transfer 403 3 mtx transfer 404 4 mtx transfer 405 5
so it should be 'startuse 1', 'enduse 80'
If you're planning on using that many tapes, yes. Only specify as many slots as you're actually intending to use in this amanda config.
Now can someone explain the following:None.
a) what is the relationship of mtx to chg-scsi
chg-scsi: is a C program that controls a SCSI tape library and directly implements the amanda changer interface described in docs/TAPE.CHANGERS. Part of the amanda source distribution.
mtx: A C program that controls a SCSI tape library and does NOT directly implement the amanda changer interface. It is very useful to use by hand, however ('mtx load 3 452' would load the tape in slot 3 to tape drive 452), and a wrapper script can convert it to amanda. Source from http://mtx.badtux.net/.
There is another, older mtx, which I have never seen in the wild.
chg-zd-mtx: A sh script wrapper around mtx which converts it to the amanda changer interface.
b) what is the relationship of chg-scsi.conf and the files in thelibexec/chg-scsi is a C program that expects to find a
/usr/local/libexec directory (/usr/local/libexec/chg-scsi)
configuration file somewhere. chg-scsi.conf might be that file.
