Dell Open Manage Server Administrator (OMSA)

Dell Open Manage Server Administrator (OMSA) is a phenomenal tool for keeping Dell PowerEdge servers running optimally!

OMSA is included with the purchase of every new PowerEdge server. It comes on a CD included in the server’s cardboard box.

Please note, however, that OMSA will not run on the “SC” (Simplified Computing) Dell server product line such as the 1425SC — only on the true PowerEdge servers.

Some examples of OMSA web page output are shown below:

My Dell PowerEdge 2650 is a few years old 🙂 so the most current version of OMSA which can be installed is 5.5

Stated another way: if you try to install a new version of OMSA like 6.3 (released July 2010), it will not install on the Dell PowerEdge 2650 — the newer version are not upward compatible, and have dropped support for older servers such as the 2650. See IMPORTANT NOTE BELOW concerning “yum update” and OMSA version 5.5 versus newer versions.

Here are my steps to install Dell OMSA in my PowerEdge 2650:

Step# Description
1: wget -q -O – http://linux.dell.com/repo/hardware/2008_Q3/bootstrap.cgi | bashThe “-q” is “quiet”The “-O” Output switch if followed by a dash (hyphen) as the filename, documents will be printed to standard output, disabling link conversion.
2 yum install srvadmin-allI am running on CentOS so use yum to install new software
3 /etc/init.d/dataeng startStarting 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 ]Please note that these will start also on a reboot (runlevels 3 and 5)
4 /etc/init.d/dsm_om_connsvc startPlease note that these will start also on a reboot (runlevels 3 and 5)
5 https://your-website-name-or-IP-address:1311/You will need to accept the self-signed certificate in Firefox (or “continue to this website” in Internet Explorer)Dell OMSA runs on port 1311. If you want to disallow remote access to OMSA, you can block port 1311 at your firewall.

PLEASE NOTE THE ADDITIONAL INFORMATION BELOW:

If you have installed versions 5.5. because it was the most recent version that was supported on your Dell hardware, e.g. PowerEdge 2650, CentOS “yum update” will want to update to a new version like 6.3 but this will NOT WORK, because it is not supported on this hardware.

Therefore, you must tell YUM to skip any OMSA update, and you do that by:


  • vi /etc/yum.conf
  • add the line “exclude=srvadmin-*” (without the quotes)

Now when you run “yum update” you will not see error messages related to trying to upgrade to an unsupported version of OMSA on this hardware platform (Dell PowerEdge 2650).
