Same issue here on R410 Centos 6.3.

Fixed it by changing the following in
/opt/dell/srvadmin/sbin/CheckSystemType

IsDELLSystem()
{
# “$SMBIOS_UTIL” | grep “OEM String 1″ | awk -F”:” ‘{print $2}’ | grep -qi
“Dell”
“$SMBIOS_UTIL” | grep “Vendor” | awk -F”:” ‘{print $2}’ | grep -qi
“Dell”

Nagios plugin to check DELL OpenManage (OMSA)

Those who doesn’t like configuring a long list of alert mechanism of on servers, here comes a savior – check_openmanage Nagios plugin. Making life easier.

More info on this plugin:
check_ checks the hardware health of Dell servers running Server Administrator (OMSA). The plugin can be used remotely with SNMP or locally with NRPE, check_by_ssh or similar, whichever suits your needs and particular taste. The plugin checks the health of the storage subsystem, power supplies, memory modules, temperature probes etc., and gives an alert if any of the components are faulty or operate outside normal parameters.

Here are some of its results:

dell-server01 ~$
OK – System: ‘PowerEdge R710′, SN: ‘XXXXXXX’, 72 GB ram (18 dimms), 1 logical drives, 2 physical drives

nagios-server ~$ check_openmanage -H dell-server02
Physical Disk 1:3 [Seagate ST3300007LC, 300GB] on ctrl 0 needs attention: Failure Predicted

It’s neat output and nagios ability to keep us alerted about server issues via email, sound alert through nagios plugins etc makes it feel good to keep a healthier RAID array running on servers.

Dell OpenManage Express Install

Dell OpenManage System Administration (OMSA) tools makes it easy to see server health, storage management, hardware health checks etc on DELL Servers from anywhere.

If you’re running RHEL5, CentOS, Scientific Linux, RHEL4+yum, SLES+yum, you can easily install DELL OpenManage System Administration Tool (OMSA) from DELL Official yum repository.  Read this link for more information Dell Hardware Repo latest.

Set up this repository:

wget -q -O - https://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash

Install OpenManage Server Administrator

yum install srvadmin-all

Once the installation is over, OpenManage services  can be start using following command.

srvadmin-services.sh start

srvadmin-services.sh start

Then access the OpenManage via browser at https://:1311

NOTE: OMSA will not install on unsupported systems. If you receive a message at install that the system is not supported, it is likely that your system is not supported, and the install will fail. This is most common on SC-class systems, as OMSA is completely unsupported on these systems.

Firewall Rule:

To enable port 1311 you can add the following rules to /etc/sysconfig/iptables on Redhat based systems.

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1311 -j ACCEPT

Save the file and restart iptables

#service iptables restart

You can also find direct links to DELL support on OMSA interface.

I used the same instructions to install OMSA on Citrix XenServer which is based on CentOS recently.
