Centos – How to monitor the hard disk status behind Dell PERC H710 Raid Controller with CentOS 6

centosdell-perchardware-raidraidstorage

I have a Dell server running CentOS 6 using PERC H710 Raid Controller card with Raid 5 setup and I want to monitor the hard disk failure/working status behind the Raid Controller.

Then I should be able to use a bash script to monitor the hard disk status and send alert emails if something went bad.

The LSI MegaRAID SAS command tool (About LSI MegaRAID SAS Linux Tools) for CentOS/Red Hat/Linux does NOT support PERC H710 and smartctl does NOT support it either.

Based on Dell website, CentOS IS not supported for this server (NX3200 PowerVault) and I couldn't download any linux program to monitor the hard disk.

[root@server ~]# lspci | grep RAID
03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 05)


[root@server ~]# smartctl -a /dev/sda
smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-431.el6.x86_64] (local build)

Anyone knows how to monitor the hard disk status behind hardware raid on Dell PERC H710 with CentOS 6?

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
