How To Manage Dell Servers using OMSA – OpenManage Server Administrator On Linux

by Ramesh Natarajan on November 17, 2008

[Dell Server] OMSA is a web based application to manage DELL PowerEdge Servers. Using OMSA you can perform proactive system monitoring, system diagnosis, troubleshoot hardware issues and configure RAID etc., You can also view and manage hardware’s embedded system management (ESM) log using OMSA.

This is an jumpstart guide that explains how to install Dell OMSA on Linux. I have also provided few screenshots of DELL OMSA web application.

1. Download DELL OMSA

Go to DELL support website -> click on “Drivers & Downloads” -> choose your server model (in my case, I selected PowerEdge 2850) -> choose the operating system -> scroll-down and expand ‘Systems Management’ -> Click on ‘OpenManage Server Administrator Managed Node’ -> Click on OM_5.5.0_ManNode_A00.tar.gz to download it. You can directly download it to your Linux server as shown below.

# mkdir -p /usr/local/omsa
# cd /usr/local/omsa
# wget http://ftp.us.dell.com/sysman/OM_5.5.0_ManNode_A00.tar.gz

2. Install DELL OMSA

Perform an express OMSA installation as shown below. After the installation, check /var/log/srvadmin.log for any installation errors.

# gzip -d OM_5.5.0_ManNode_A00.tar.gz
# tar xvf OM_5.5.0_ManNode_A00.tar
# sh linux/supportscripts/srvadmin-install.sh --express
Installing the selected packages.

3. Start DELL OMSA Services

Invoke the srvadmin-services.sh script to start the OMSA services as shown below.

# sh linux/supportscripts/srvadmin-services.sh start
Starting Systems Management Device Drivers:
Starting dell_rbu:                                         [  OK  ]
Starting ipmi driver:                                      [  OK  ]
Starting Systems Management Data Engine:
Starting dsm_sa_datamgr32d:                                [  OK  ]
Starting dsm_sa_eventmgr32d:                               [  OK  ]
Starting DSM SA Shared Services:                           [  OK  ]
Starting DSM SA Connection Service:                        [  OK  ]

4. Access OMSA from web browser

By default, OMSA web application runs on Port 1311 . Login to OMSA from web using the URL: https://{omsa-server-ip-address}:1311 using root as shown below. Please note that you can login only using HTTPS.

5. Check overall system health of the server

To check the overall system health of various hardware components, expand system menu and click on ‘Main System Chassis’, which will display the health of Memory, CPU etc., as shown below.

6. Clear System Event Log on DELL PowerEdge Servers

Sometimes you will see hardware error messages on the front side of the server even after the problem is fixed.  To clear this false alarm,  you have to clear the hardware’s Embedded System Management (ESM) Log. To clear hardware event logs, login to DELL OMSA -> Click on Logs TAB -> click on Clear Log.

7. Create RAID (Virtual Disk) group using OMSA

To create a new raid group, click on Storage -> select “Create Virtual Disk” from the drop-down menu next to “PERC 4e/Di”, as shown below. -> Click on Execute -> and follow the on-screen instructions to create a new RAID group.

DELL OMSA Create RAID

You can also create RAID using PERC/CERC Bios Configuration Utility as explained in Step-by-Step Guide to Configure Hardware RAID on DELL servers with Screenshots.

Once the RAID group is created, to view the RAID, click on Storage -> “PERC 4e/Di (Embedded)” -> Click on “Virtual Disks” -> Click on “Virtual Disks 0″ -> This will display the details of the physical disks of that particular RAID group as shown below.

Great article. Simple, easy to understand. Thanks for helping out !

2 John Morris November 19, 2008 at 1:46 am

Hey, nice article, much easier than wading through all the Dell CD documentation.

Any instructions for if we want to install from RPM instead?

Thanks!

3 John Morris November 19, 2008 at 1:49 am

Never mind, I see that these indeed ARE RPMs! Thanks! You rock.

4 Scott Larsen December 11, 2008 at 7:31 pm

Good article.

One thing to note (and that has got me a few times) is that you want to make sure that OMSA is installed in a directory that is part of a filesystem that is mounted *BEFORE* the “start_udev” script runs, which is part of rc.sysinit (at least in RedHat).

This means, in every case that I can think of, that it needs be be installed in a directory based off the root filesystem.

I used to install OMSA in /opt, but kept wondering why I was getting errors on startup. I discovered that /opt wasn’t mounted when rc.sysinit (and thus start_udev) ran. DUH! :)

Just a tidbit…..

Learned a little trick. Received this error on CentOS 5.3 & OM_6.1.0_ManNode_A00 -

[root@myhost omsa]# sh linux/supportscripts/srvadmin-install.sh –express

Unsupported Operating System. Can not proceed….

FIX –
Comment out the CentOS line with “(Final)”, and add in “(Tikanga)”

[root@myhost omsa]# vi /etc/redhat-release
#CentOS release 5.3 (Final)
CentOS release 5.3 (Tikanga)

Hope that helps someone.

6 CraigM September 28, 2009 at 4:19 pm

CentOS release 5.3 (Tikanga) fix helped… Thanks FastEddy760!!

7 deltatech October 2, 2009 at 9:32 pm

I tried the Tikanga fix but still get unsupported system.

Unsupported system (sysid=0181)

Any ideas?

8 Ren January 25, 2010 at 4:00 pm

You have to comment out one or the other. Alternatively you could edit in
Red Hat Enterprise Linux Server release 5.3 (Tikanga) via /etc/redhat-release

Hi Ramesh et al,
~
after installing the deb omsa packages on a Debian base omsa seems to start on its own:

Any tips on how to troubleshoot this problem

FastEddy is correct in his posting above. I went thru these exact steps for my old faithful Dell PE1750 a few moments ago. The installer failed with NO output and an error code 2 on CentOS 5.5.

By editing /etc/redhat-release and adding the word “Tikanga” to the end of the line, I was able to proceed with the install and was up and running in no time.

11 Sire July 16, 2010 at 7:52 pm

As a followup, today I went a step further with version 6.2 of the OMSA software on 6 of my newer PE1950′s (same link as in this document, but changed the filename to OM_6.2.0_ManNode_A00.tar.gz). Again, running Centos 5.5 and adding the string “Tikanga” (the “t” must be capitalized) I was able to install this flawlessly exactly as shown here.

This posting has been a lifesaver. I’m now monitoring nearly a dozen Dell’s in a NOC that’s 1/5 hours away. No more showing up with surprise amber flashing lights!

THANKS EVERYONE FOR THIS POSTING!!!

12 KK August 23, 2010 at 2:49 am

I do not have webserver installed in my server, is there any alternatives I can use the OMSA in Linux server?

13 DenyAll October 6, 2010 at 12:39 pm

If you’re running Red Hat Enterprise Linux, you can do:
# wget -q -O – http://linux.dell.com/repo/hardware/bootstrap.cgi | bash
# yum -y install srvadmin-storage srvadmin-base

14 Chuck November 15, 2010 at 3:08 pm

This is a great article. I’ve been wanting to monitor the disks on our 2950 Dell servers running SuSE SLES 10 for some time. To get the software, I couldn’t use the browser, but was able to use ftp going to http://ftp.dell.com/sysman and downloading the appropriate package for my server.

15 Joe January 29, 2011 at 9:31 pm

Building on FastEddy760′s trick (which works great) for an earlier version:

#CentOS release 4.8 (Final)
CentOS release 4.8 (Nahant)

16 sylvain February 10, 2011 at 10:10 am

works fine with OEL 5.3
Thanks

17 Ariel Rivera September 26, 2011 at 2:05 pm

Again, thegeekstuff saved me from the hole I was in.
One would think vendors like Dell in this case should provide this kind of documents….

18 Pierre B. May 4, 2012 at 5:20 am

I just wanted to promote myself! i wrote two posts about the omreport cli and its usage. Hope this will help someone in any possible way.

thx TGS!

19 Moses May 9, 2012 at 3:42 pm

i am unable to install OMSA on fedora 14, nothing happens after the command to install…
# sh linux/supportscripts/srvadmin-install.sh –express

Just goes back to the prompt…. any ideas/suggestions will greatly appreciated

20 Pierre B. August 14, 2012 at 4:23 am

@ Moses :
Sorry for being late, but better later than never ?

1) What is the hardware on which you are trying to install OMSA ?

2) You might want to try the install without the “–express” option to see if you can get more infos ?

3) You may also want to check what is behind your “sh” command ?

4) Finally you should run the install script using the “-x” option to get more traces :
bash -x linux/supportscripts/srvadmin-install.sh

Hi, Thank you very much for the guide about the “Dell Open Manager Server Administrator” for linux.

22 Mac May 31, 2013 at 3:59 pm

Can you post install instructions for RHEL 6 / CentOS 6 ?

Great site!

23 Eddy June 3, 2013 at 2:51 pm

Hey Mac,

No longer messing with OMSA, however there should be a README file with the software.

If you are still under support with Dell, they actually have an excellent Linux/Unix team. Will have good answers.

Also, the previous comments hint at the install steps, starting with the command from Pierre B., step 4.

24 David Moore August 28, 2013 at 9:07 am

Brilliant, thank you so much, allowed me to use a spare disc to give further redundancy without rebooting / deleting an array.

25 john little November 21, 2013 at 7:32 am

We have Centos 5.6. i tried the RHEL 5.x version from the dell site. installing as instructed gives this:

Warning: The lockfile utility is not found in PATH or /usr/bin.
This utility prevents concurrent executions of srvadmin-install.sh
which can lead to unexpected or invalid installation results.

Unrecognized Operating System or Architecture. This script cannot
continue with the installation. Select rpms from the OS folder in
the media that closely matches this Operating System to continue
with the manual install.

I guess that dell does not suport Centos, which is what most companies here use.

26 john little November 21, 2013 at 7:42 am

Tried the (Tikanga) hack. Dont get the unsupported OS, but now get this:

Upon running the install line it returns:

Any Help?

28 Sid January 29, 2014 at 6:12 pm

So if I have 50+ servers I need to install on everyone? Is there a central administration console that can find all 50+ servers and manage the lot as a single entity?

Thanks

Sid

29 Kim June 6, 2014 at 6:16 am

Can I monitor iDRAC with OMSA?

30 Dag June 7, 2014 at 10:39 am

Can you put up a newer update with newer CentOS 6.x release installing OMSA 7.4 release with step by step instructions and screenshots?

thanks
Dag

31 renu July 30, 2014 at 7:39 am

I installed the OMSA as per the article. Everything went fine. I am not able to accesss my system from the web console. I am getting connection error. Also
I tried the below command on the system and error as follows.

wget https://locathost:1311
–2014-07-30 09:37:58– https://locathost:1311/
Resolving locathost… failed: Temporary failure in name resolution.
wget: unable to resolve host address `locathost’

I disabled firewall and selinux

Any ideas on troubleshooting?

32 Ian Button August 8, 2014 at 4:13 am

@renu, Afraid you have got the url misspelt – try localhost with L not T

33 Jay August 19, 2014 at 6:34 am
