I figured it out: I didn't quite understand how to define a `slot' in
a rait using chg-robot: something like '{1,13}' does the trick.
One question: should the changerfile parameter for chg-robot point to
the same file for both child-changers:
define changer av48-1 {
tpchanger "chg-robot:/dev/changer"
changerfile "/etc/amanda/av48-state-1"
property "tape-device" "0=tape:/dev/nst0"
property "eject-before-unload" "yes"
property "use-slots" "1-12"
property "load-poll" "20s poll 40s until 120s"
property "status-interval" "10s"
}
define changer av48-2 {
tpchanger "chg-robot:/dev/changer"
changerfile "/etc/amanda/av48-state-2"
property "tape-device" "1=tape:/dev/nst1"
property "eject-before-unload" "yes"
property "use-slots" "13-24"
property "load-poll" "20s poll 40s until 120s"
property "status-interval" "10s"
}
tpchanger "chg-rait:{av48-1,av48-2}"
I like the new polling stuff. It will makes my life much easier!
There is a lot of new exciting stuff. Good work guys!
