We got a couple of HP ProLiant DL380 G7 servers, and this is what HP has to offer for being certified for Ubuntu: Management Component Pack (on its Software Delivery Repository).
And here’s how to set it up on Ubuntu 12.04 LTS.
Add the following to /etc/apt/sources.list:
deb http://downloads.linux.hp.com/SDR/downloads/MCP/ubuntu precise/current non-free
Download and add the repo keys to the system:
wget http://downloads.linux.hp.com/SDR/downloads/MCP/GPG-KEY-MCP
apt-key add GPG-KEY-MCP
Finally, get the list of packages from the repo and install whichever packages required (hpacucli to configure the disk array controller):
apt-get update
apt-get install hpacucli
Done!
