How to monitor the hard disk status behind Dell PERC H710 Raid Controller with CentOS 6?
Solution 1:
You can see the SMART status of the disks with the smartctl command and it's -d argument. For example, to see the first disk in the array:
# smartctl -a /dev/sda -d sat+megaraid,00
smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-358.6.2.el6.x86_64] (local build)

This is on Scientific Linux 6 (another RHEL6 based OS) with smartmontools-5.43-1.el6.x86_64.

S.M.A.R.T. is not the final word in disk or storage monitoring!! It's a component, but modern RAID controllers use it along with other methods to determine drive and array health.
I'm assuming this is a PERC controller in a Dell PowerEdge server.
The normal Linux-friendly approach to health monitoring of Dell hardware is to install the Dell OMSA agents for Linux via Yum - http://linux.dell.com/wiki/index.php/Repository/OMSA#Yum_setup
yum install srvadmin-all will install the full suite of agents. Once installed, you can use the omreport command to get information about your array.
Examples:
$ omreport storage vdisk
$ omreport storage pdisk controller=0
$ omreport storage vdisk controller=0 vdisk=1
Solution 3:
The accepted answer recommends the audacity that is yum install srvadmin-all. Blecch. Here's how to make it slightly less blecch-y (but still blecch-y nonetheless; you can get much leaner on HP's platform. But I digress...) By this I mean, only install those components necessary to manage storage on your machine.
BTW, the direct answer to the user's question lies in the item "Show physical disks on vdisk 0" in the list below.
wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi > bootstrap.cgi
bash bootstrap.cgi
yum install srvadmin-base
yum install srvadmin-storageservices
Add to root's .bashrc:
export PATH=$PATH:/opt/dell/srvadmin/bin

$ omreport storage pdisk controller=0 vdisk=0Reconfigure a vdisk to be raid1 from raid0 (COOL!!!!)

BTW, since this IS nothing more than a Dell-branded LSI MegaCLI card, you might find Han Solo's answer even better! I have yet to try it, however.

Here's an example of omreport's output, piped through grep for a delicious bundle of data:

I was struggling also to get it work in CentOS and I found a working package here http://mirror.ndchost.com/software/lsi/
called "MegaCli-8.07.10-1.noarch.rpm"
The command reference http://hwraid.le-vert.net/wiki/LSIMegaRAIDSAS
I hope it helps.
