I've been juggling configs for two days to try to use my HP SureStore 24x6 
with amanda with no luck.

My hopes were high when I found this article: 
http://www.soti.org/~soggie/linux/hw/hp-surestore-24x6/ but as it's always 
the case with me and how-to's it din't solve it. I'm guessing I have 
something wrong in my charger config file. I keep reading other people's 
posts about "having to change one line in the mtx script" but never found 
more info on where and how. 

For the record, mt and mtx seem to work fine from command prompt. I can load 
tapes, move to next or previous rewind etc the only thing that doesn't seem 
to work so far is eject.

The message I get when issuing amcheck:

-bash-2.05b$ /usr/sbin/amcheck DailySet1
Amanda Tape Server Host Check
-----------------------------
Holding disk /var/tmp: 7856688 KB disk space available, that's plenty
amcheck-server: could not get changer info: badly formed result from changer: 
"/usr/lib/amanda/chg-zd-mtx: line 140: [: -eq: unary operator expected"

Amanda Backup Client Hosts Check
--------------------------------
Client check: 1 host checked in 0.143 seconds, 0 problems found

(brought to you by Amanda 2.4.2p2)



Here is the pertinent parts of config files:

Any help is truly appreciated. TIA
