Hello.
Thanks for responding.
Our systems are all based on FreeBSD 4.3-RC3, I forgot to mention that.
well, the backup operator is 'operator' and this user has full read/write
permissions to the tape device (/dev/nsa0, /dev/nrsa0).
whenever I put any line into "changer.conf" as configured with "changerfile"
in amanda.conf I receive errors about that line - so I omit all lines, I simple
"touch" a changerfile 'changer.conf' to get the control files as expected from
"chg-manual".
When trying 'amcheck config' I get some infos about the holding disk and I was
offered to insert a tape in slot 0 - and I should hit return. either I do immediately
while the tape is already loaded into the HP DAT (4 GB DDS-2 drive) or I eject and
reload it again, wait for the tape to be initialised and the hit return. Always
with the same effect: I was offered to hit return again and load a tape into
slot 0 - but nothing happened to the tape inserted into the tapedrive.
When checking /tmp/amanda/changer.debug then I get a big file with this:

Well, it seems to be all right, tape is loaded, clear to be written on - but
whats going on with the changer?
It seems not to be willing to write anything :-(
A normal tar, mt operations and so on work well with the tape and as user 'operator',
so that is not a kind of a permission issue.

:>Dear Sirs.
:>
:>I already set up a HP SureStore 6x40i changer based tape device

:>
:>If I'm right, I have to setup the following in amanda.conf:
:>
:>(here are only the relevant entries)
:>
:>tpchanger "chg-manual"
:>tapedev "/dev/nsa0"
:>changerfile
:>"/usr/local/perfector/amanda/services-backup/changer.conf"
:>
:>The entry "changerfile" should be set due the fact, that chg-manual driver

:>changerfile.
:>If I omit this, I receive an error. The targeted changerfile is either empty
:>or
:>I configure some parameters like slot /dev/nsa0 etc.
:>
:>But I receive allways the same result. After typing "amlabel -f CONFIG
:>CONFIGLABEL slot [0-9]
:>(I tried slot 0 to 9, but configured either slot 0 or 1, for testing

:>
:>Can anybody help? What to be aware of when configuring a chg-manual device?
