I quickly needed to determine the status of a RAID array that sat on an IBM ServeRAID adapter. The boxen was running Ubuntu 9.04 x86_64, I didnt want to install RaidManager nor did I want to install a debian package. Here's how.

$ wget http://hwraid.le-vert.net/debian/pool-lenny/arcconf_6.10.18451-1_amd64.deb
$ ar -x arcconf_6.10.18451-1_amd64.deb
$ tar zxvf data.tar.gz
$ sudo ./usr/sbin/arcconf GETCONFIG 1

Install the debian package if you need.
