Hi All,
I am having an issue where my superloader 3 LTO3 changer goes through
and reads all FULL slots until it gets to 16. So, tapes are loaded
and read until 16 slots are read, but it is reading the same slots
over and over.
I have 16 slots, but only am using 7 of them right now. The result is
that I am getting WAY more wear on my changer than I should be getting
(and time is wasted).
Is there a way to get barcodes working in this version of amanda so
that it wouldn't even have to do the reads, and if not, is there a way
to tell it to stop reading until it gets to 16 (ONLY READ FULL SLOTS)???
Note that it does this every run AND every amcheck. . .
Details:
amanda version 2.6.0p2
CentOs 5.2
Quantum Superloader 3 LTO3 16 slot
changer.conf:
changerdev=/dev/sg3
firstslot=1
lastslot=16
havebarcode=1
havereader=1
poll_drive_ready=10
Max_drive_wait=99
unloadpause=10
driveslot=0
offline_before_unload=1
OFFLINE_BEFORE_UNLOAD=1
A simple change, if you are only using 7 slots, would be to have lastslot=7.
I'm using chg-zd-mtx with Amanda 2.5.1p3 on Solaris 9 and it seems to
work alright. There are some instances where it will scan ahead, but
there are also some where it will go straight to the correct tape.
Typically, I avoid both situations by having the tapes in the sequence
they will be used, so Amanda just takes the next tape up.
I will very shortly have another system up that will be the same kind of
16 slot changer, chg-zd-mtx, Amanda 2.6.1 (just downloaded yesterday),
and Solaris 10.
