A client has a machine in a DC that has a raid controller and 4 hdd’s set to raid 10, that’s all I was told. I wanted to keep an eye on the hdds, so I needed to install a utility that can monitor and interact with the raid controller. In my case I have the hp smart array raid controller as you will see in just a bit, you may have a different controller from this one by a different manufacturer, or it may require a different version of the software tool from HP, please check on the HP site linked below before continuing on. There is a chance of serious data loss if you don’t follow common sense practices and MAKE BACKUPS. I needed to do a few things, find out which controller is it, find latest of control utility for it, install said utility and then check on the drives. that isnt always easy, sadly.
First we check who makes this system.
dmidecode | grep -A3 ‘^System Information’
Sample result:
System Information
Manufacturer: HP
Product Name: ProLiant DL160 G6
Version:
Second we check lspci to see what controller we have installed.
lspci -k|grep -i -A2 raid
Sample Result :
04:00.0 RAID bus controller: Hewlett-Packard Company Smart Array G6 controllers (rev 01)
Subsystem: Hewlett-Packard Company Smart Array P410
Kernel driver in use: hpsa
Now we know we have a HP machine, DL160 G6 to be exact in this case, and the exact rev of the card itself. We need to install the HP provided software for it. The official HP software page for the information below is here. However as its laid out, best of luck getting up and running quickly if you follow that page.
Get and install HP Keys. (Keys are in the following order: software release pre 2014, during 2014, and post 2014)
curl http://downloads.linux.hpe.com/SDR/hpPublicKey1024.pub | apt-key add - curl http://downloads.linux.hpe.com/SDR/hpPublicKey2048.pub | apt-key add - curl http://downloads.linux.hpe.com/SDR/hpPublicKey2048_key1.pub | apt-key add -
Add the HP repo (be sure to change the jessie to whatever your release is):
echo -e "deb http://downloads.linux.hpe.com/SDR/repo/mcp/ jessie/current non-free" > /etc/apt/sources.list.d/hpe.list
Then update sources and install package :
apt-get update && apt-get install hpssacli
Now you have the tools needed for the job! so run the utility
hpssacli
sample result:

Hope this helps some of you out as it took me a little bit to get all the information together for my setup, so I’m storing it here for future usage 🙂
