I'm hoping that somebody out there with more experience with setting up
chg-scsi could help point out the cause of my misconfiguration. In
attempting to use chg-scsi on my 15-tape changer, I suffer from the
following errors:
[EMAIL PROTECTED]:/usr/local/etc/amanda/daily$ amcheck daily
Amanda Tape Server Host Check
-----------------------------
Holding disk /ambackup/daily: 109239520 KB disk space available, that's
plenty
amcheck-server: could not get changer info: check your config and use an
config file for chg-scsi
Amanda Backup Client Hosts Check
--------------------------------
Client check: 15 hosts checked in 0.988 seconds, 0 problems found
(brought to you by Amanda 2.4.3b2)
[EMAIL PROTECTED]:/usr/local/etc/amanda/daily$
Similar command calls direct to chg-scsi (such as -status robot) results
in the same errors. The only working command is "chg-scsi -genconf",
which I used to create a configuration file, chg-scsi.conf. This config
file is owned by the ambackup users with appropriate read/write perms:
-rw-r--r-- 1 ambackup ambackup 2564 Jul 28 15:06 chg-scsi.conf
When running the chg-scsi command, the entire debug output consists of:
chg-scsi: debug 1 pid 92238 ruid 10080 euid 10080 start time Mon Jul 28
16:55:52 2003
chg-scsi: $Id: chg-scsi.c,v 1.6.2.22.2.7.2.2 2001/12/30 17:26:22
martinea Exp $
ARG [0] : /usr/local/libexec/amanda/chg-scsi
ARG [1] : -info
My amanda.conf file is configured to point at this config file location.
Attached are the chg-scsi.conf and amanda.conf files.
I am using Amanda 2.4.4 on FreeBSD 4.8-STABLE.
Thanks in advance!
