[Bacula-users] please test autoimporttscript with a charger
2010-03-21 16:52:09
Hi all,
I 've written an autoimportscript for charger that search the last full
mailslot, last empty slot and transfer a tape from mailslot in the last
empty slot. Please help me to make my script a little bit better. I can
only test the script with charger with one mailslot. If you have a
charger with more mailslots, please test my script! I need the script to
import for weekly tapes from a safe.
requirements:
-charger with one or more mailsslots # test ibm ts3100 with bacula 3.0.2
under sles 11
-labeled tapes
here the script:
---------------------------------------------------------------------------------------
#!/bin/bash
#these script is for a automatic import from mailslots in freeslots of
charger as runbeforejob.sh in bacula type admin
#the function searches the last freeslot, the last full mailsslot, bring
tape in the freeslot and to start over to no freeslot or full mailslot
available!
#You have to setup it! Look under bacula-sd.conf item "Autochanger"
subitem "Changer Device = XXXXX"
CHANGERDEVICE=/dev/sg1
#You have to setup it! Look under bacula-dir.conf item "Storage" subitem
"Name = XXXXX"
STORAGE=Tape-Storage
