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

[root@server ~]# smartctl -a /dev/sda

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

    this will install extra components such as web server/ssl on my Linux machines but it seems that I have no other choice! I hate to add unnecessary packages into my server. – Xianlin Apr 16 '14 at 15:40

    Beware of potential memory leak from one of those OMSA programs. It happened to me slowly over the course of 3-4 weeks then boom, no more memory at all for linux. – bksunday Jan 19 '15 at 19:37

    Yes, the leak is in dsm_sa_snmpd (so I run 'killall -9 dsm_sa_snmpd', solved). – markusN Jan 21 '15 at 10:54

    The PERC 7xx and 8xx controllers are just LSI Megaraid controllers and the LSI MegaCLI tool will work just fine if you dont want to taint your system with dell libraries and whatever other services and/or kernel modules they are dropping these days. There are plenty of MegaCLI cheat sheets, nagios monitoring scripts and performance tuning tips out there for the LSI binary. That is just my personal preference and opinion of course. I am a minimalist. – Aaron Feb 16 '16 at 4:23
  • @Xianlin, this is not entirely true. Yes, it will install a lot of garbage but see my answer. I didn't want to add unnecessary packages so I figured out only the ones I needed for storage. – Mike S Apr 5 '16 at 20:06

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

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

Enjoy:

RAID Commands

  • Show all physical disks on controller 0

    omreport storage pdisk controller=0

  • Show all logical disks on controller 0

omreport storage vdisk controller=0

  • Show all physical disks on vdisk 0

omreport storage pdisk controller=0 vdisk=0

  • Reconfigure a vdisk to be raid1 from raid0 (COOL!!!!)

omconfig storage vdisk action=reconfigure controller=0 vdisk=1 raid=r1 pdisk=0:0:2,0:0:3

  • Create a vdisk on a new disk:

omconfig storage controller controller=0 action=clearforeignconfig omconfig storage controller controller=0 action=createvdisk raid=r0 size=max pdisk=0:0:2

How do I reconfigure my disk array on a Dell machine under Linux?

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.

The Sweetness

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.

    I would absolutely agree, use /opt/megacli/MegaCli64 -PDList -aALL | grep -i firmware and it'll tell you if the physical disks are ok. (Command is from erikimh.com/megacli-cheatsheet - see it if I used the wrong one). Basically the raid care does a great job of monitoring the disks, so just keep track of it's opinion of the disks' operating states. – Some Linux Nerd Apr 5 '16 at 22:18

    Please consider reading How do I write a good Answer? in our help center and then revise the Answer. Your Command may technically be a solution, which was also already mentioned in the other, much older answers and some explanation is welcome. Thanks in advance. – HBruijn Sep 15 '15 at 10:00

    The other answer used "sat+megaraid", which did not work for me. (Right, I did not know the smartctl command well and did not know to how alter the command to make it work.) This answer led me on the right path, and it works for me. – Yongwei Wu Feb 6 '17 at 2:47

The perccli command can also show you a lot of drive info if you ask it nicely:

# /opt/MegaRAID/perccli/perccli64 /c0/e32/s0 show all
Controller = 0
Status = Success
Description = Show Drive Information Succeeded.


Drive /c0/e32/s0 :

EID:Slt DID State DG       Size Intf Med SED PI SeSz Model            Sp

Drive /c0/e32/s0 - Detailed Information :

Drive /c0/e32/s0 State :
======================
Shield Counter = 0
Media Error Count = 0
Other Error Count = 0
Drive Temperature =  40C (104.00 F)
Predictive Failure Count = 1
S.M.A.R.T alert flagged by drive = Yes

This needs to be repeated for each enclosure slot, or at least I haven't found a way to print all of it at once with a single perccli command.

It's also easy to install compared to other, more comprehensive options:

# curl -C - -O 'https://downloads.dell.com/FOLDER04470715M/1/perccli_7.1-007.0127_linux.tar.gz'
# tar xzvf ../perccli_7.1-007.0127_linux.tar.gz
# cd Linux/
# yum localinstall perccli-007.0127.0000.0000-1.noarch.rpm
# cd /opt/MegaRAID/perccli/

perccli is NOT a comprehensive monitoring suite like Delll OMSA, but it sounds like many folks don't want something comprehensive and instead need a decent, simple tool.

Hi I have a similar Dell PERC/LSI card and I needed to check the RAID status. LSI have a utility called sas2ircu which I found quite useful, there is also a version for Windows and Linux.
