Hi!
During the last two days I configured Amanda to work with a Overland
Library (Overland LoaderXpress, 11 Slots, 1 LTO-1 drive) under SUN
Solaris V8. After studying some threads here and on the web it was no
problem to get the changer running (if someone is interested in doing
it I can give a detailed explanation - feel free to ask!!).
All commands (like "amtape <config> slot next", "amtape <config> slot
prev", "amcheck <config>) are working really fine. I hadn't have any
errors.
My amanda.conf looks like this:
--- SNIP
dumpuser "amanda"
inparallel 4
dumporder "sssS"
dumpcycle 1 weeks
runspercycle 5
tapecycle 5 tapes
bumpsize 20 Mb
bumpdays 1
bumpmult 4

dtimeout 1800
ctimeout 30
tapebufs 40
runtapes 2
tpchanger "chg-zd-mtx"
tapedev "/dev/rmt/1cn"
changerfile "/etc/amanda/edvchanger/chg-zd-mtx.conf"
changerdev "/dev/scsi/changer/c3t4d0"
maxdumpsize -1

labelstr "^sun-edv-[0-9][0-9][0-9]*$"

amrecover_check_label yes

}
autoflush no

}
define dumptype always-full {

comment "Full dump of this filesystem always"

}

The "chg-zd-mtx.conf" looks like this:
--- SNIP
firstslot=0
lastslot=9
cleanslot=10
--- SNAP
The "disklist" looks like this:
--- SNIP
A /dev/sda5 always-full # 1.5G

This means a total capacity for backup of round about 117G.
I thought, 2 tapes (specified in runtapes) should be enough and
amanda would change the needed tapes automatically.
I started the first backup "amdump edvchanger".
It was horrible. The complete SUN-Server crashed!!
There was no response to pings and no chance to get a console over
the rsc-board....
Here are some snippets out of the logfile "amdump":

Server "A" and "B" are RedHat 9 Linux Machines running Amanda 2.4.4p3.
Anyone any ideas??? Thanks in advance.
