Hi,
Solaris 9 (sun4u) bacula-2.0.2 (recently upgraded from 1.36.1)
[Mysql 4.0.21 Solaris 8,9,10, Linux 2.6 (FC5 & GENTOO), WIN-32 (WIN-XP)
Clients.]
- Bacula built from source.
- Director & Storage Daemon on same machine.
- Storage device LTO STOREDGE-L8 Autochanger (Actually an HP autochanger).
------------------------------------------------------------
Having recently upgraded my site, bacula ran ok until the current volume in my
autochanger filled up then
an automatic media change failed.
Initially, the mtx-changer script didn't work properly (apparently it was
updated in the upgrade).
I found a solaris specific version in
examples/autochangers/solaris-mtx-changers which I have attempted to use
(having set the correct paths to mtx). [also having found that I actually had
two version of mtx on my system one took a -d flag the other took a -f
flag!!!!! - so I messed things up a bit there].
Now, when I run this script manually : e.g.
./mtx-changer /dev/scsi/changer/c1t0d0 loaded 1 /dev/rmt/1mbn
It seems to work ok & returns the correct value saying e.g. slot 6 is loaded.
However in bconsole.
* status storage
Gives:
Device status:
Device "STOREDGE-L8" (/dev/rmt/1mbn) is mounted with Volume="backup029"
Pool="*unknown*"
Drive 0 status unknown.
Total Bytes Read=0 Blocks Read=0 Bytes/block=0
Positioned at File=0 Block=0
I have only ever used the default pool. - I don't recall getting "*unknown*"
before!.
However:
* update slots scan
Gives:
The defined Storage resources are:
1: File
2: HP-DDS3 4mm DAT Loader
3: STOREDGE-L8
Select Storage resource (1-3): 3
Connecting to Storage daemon STOREDGE-L8 at aaaaaaaaaa:9103 ...
3995 Device "STOREDGE-L8" (/dev/rmt/1mbn) is not an autochanger.
Enter autochanger drive[0]:
Bacula no longer thinks my autochanger is really an autochanger!!
Obviously something has changed that I am not aware of.
Relevent bits from my config files......
bacula-dir.conf:

}

I attach my mtx-changer script(slightly fixed paths) which should not be
causing a problem.. but since its in the "critical Path" here it is!.
Any help/suggestions gratefully received.
Many Thanks

# If you set in your Device resource
#
# Changer Command = "path-to-this-script/mtx-changer %c %o %S %a %d"
# you will have the following input to this script:
#
# mtx-changer "changer-device" "command" "slot" "archive-device" "drive-index"
# $1 $2 $3 $4 $5
#
# for example:
#
# mtx-changer /dev/sg0 load 1 /dev/nst0 0 (on a Linux system)
#
# If you need to an offline, refer to the drive as $4
# e.g. mt -f $4 offline
#
# Many changers need an offline after the unload. Also many
# changers need a sleep 60 after the mtx load.
#
# N.B. If you change the script, take care to return either
# the mtx exit code or a 0. If the script exits with a non-zero
# exit code, Bacula will assume the request failed.
