nice, after 10min i got it working on ubuntu

first of all you gotta download the linux storage manager client. I grabbed it from my DS storage DVD i got with my DS3300.
If you’re running ubuntu/debian you will need those packages:
apt-get install rpm sun-java6-jre

after you get the disk content, launch the bin file:
./SMIA-LINUX-10.60.A5.14.bin it will extract the needed files to /opt/IBM_DS/
afterwards use the rpm extract command from /opt/IBM_DS:
rpm2cpio SMclient.rpm | cpio -vid
next, move the client folder from /opt/IBM_DS/opt/IBM_DS/client to just /opt/IBM_DS/client
otherwise you can just extract the rpm from root (/) and it will put the files where they should be.
anyway after you finish, edit: client/SMcli like this:
#JAVA_EXEC=$BASEDIR/jre/bin/java
JAVA_EXEC=/usr/bin/java
and save it.
Now you ready, the rest are as described in the readme or here in this page.

I have one question, the plugin displays in nagios status information only this: “OK STORAGE SUBSYSTEM TOTALS”
but when i launch the check manually from the shell i also see the values followed by the pipe:
OK STORAGE SUBSYSTEM TOTALS | ‘Current B/second’=10252288 ‘Current IO/second’=139;150;500

it would be great also to bring those values to the nagios web console so you know where you stay and learn better your system.
thanks.
