Linux - hpacucli


This document is a quick cheat sheet on how to use the hpacucli utility to add, delete, identify and repair logical and physical disks on the Smart array 5i plus controller, the server that these commands were tested on was a HP DL380 G3 server with a Smart Array 5i plus controller with 6 x 72GB hot swappable disks, the server had Oracle Enterprise Linux (OEL) installed.
After a fresh install of Linux I downloaded the file hpacucli-8.50-6.0.noarch.rpm (5MB), you may want to download the latest version from HP. Then install using the standard rpm command.
I am not going to list all the commands but here are the most common ones I have used thus far, this document may be updated as I use the utility more.
