When AMANDA looks at your tape hardware, she needs to 'see' two separate
devices: one is the tape drive, where tapes are read and written. Usually
only one tape can be in the drive at a time. The rest of the hardware that
holds and moves tapes is a tape changer. (The exception is some gravity-fed
stackers, which advance to the next tape on eject. If you can access your
tapes in any order, you don't have one of those.)
Depending on your operating system, your tape drive might be called
/dev/nst0 (first non-rewinding SCSI tape) and your changer might be /dev/sg0
(first SCSI generic device).
You should probably just get AMANDA working with the tape drive first, and
then add the changer later. There is a changer type called chg-manual which
is used when you can't or don't want to use a robotic changer. (You just
don't want to use it /yet/.)
Because there are so many different changers on so many different operating
systems, configuration can be complex and time-consuming. Read through the
mailing list archives for some other users' solutions. You might even find
your operating system and changer.
And if the archives can't help, we'll still be here.

Subject: Input/Output Errors
I have a tape drive that can handle up to 8 tapes.
It is a Sony DDS3 and I have put 7 data tapes and 1 cleaning tape in it.
When I run amcheck I get the following message
Amanda Tape Server Host Check
-----------------------------
/usr/local/amanda/dumps: 1923276 KB disk space available, that's plenty.

Amanda Backup Client Hosts Check
--------------------------------
Client check: 1 host checked in 0.182 seconds, 0 problems found.
(brought to you by Amanda 2.4.1p1)
What can I check to find out why I am getting this error message.
If i run the chg-multi file ( from libexec ) and pass commands like
/usr/local/amanda/libexec/chg-multi -slot current
response -
8 /dev/nst1
but if i run
/usr/local/amanda/libexec/chg-multi -slot advance
i get -
1 /dev/null
I think that this has something to do with the problem, but I have no idea
where to look :-((
I am hoping that somebody does!! I'll await your replies
Thanks
Nathan
