Admin Mistake: Dell OMSA Not Running Properly on CentOS

Background
The concept is that you have some Dell R610 server running CentOS 5.8 operating system and you are using Dell OMSA command line utilities to perform the hardware monitoring.

Problem
The monitoring checks are failing with “Unknown” status and if you attempt to locally execute the equivalent commands there is no response. For example:

[root@somewhere ~]# omreport chassis
Health

For further help, type the command followed by -?
[root@somewhere ~]#

Which of course is not the correct output.

Mistake
My initial thought was that it was missing the compatibility C++ standard library but this was not the case.

[root@somewhere ~]# rpm -qa|grep compat-libstdc++
compat-libstdc++-33-3.2.3-61
compat-libstdc++-296-2.96-138
compat-libstdc++-33-3.2.3-61
[root@somewhere ~]#

The problem was that “Systems Management Data Engine init script” was not configured to start on boot. Consequently, the required services were stopped after a reboot.

[root@somewhere ~]# service dataeng status
dsm_sa_datamgrd is stopped
dsm_sa_eventmgrd is stopped
dsm_sa_snmpd is stopped
[root@somewhere ~]#

Resolution
Quite simple… First start the init script.

[root@somewhere ~]# service dataeng start
Starting Systems Management Data Engine:
Starting dsm_sa_datamgrd:                                  [  OK  ]
Starting dsm_sa_eventmgrd:                                 [  OK  ]
Starting dsm_sa_snmpd:                                     [  OK  ]
[root@somewhere ~]#

And then make it start on boot…

[root@somewhere ~]# chkconfig dataeng on
[root@somewhere ~]# chkconfig --list dataeng
dataeng         0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root@somewhere ~]#

Obviously, the utilities are now working properly.

[root@somewhere ~]# omreport chassis
Health

Main System Chassis

SEVERITY : COMPONENT
Ok       : Fans
Ok       : Intrusion
Ok       : Memory
Ok       : Power Supplies
Ok       : Power Management
Ok       : Processors
Ok       : Temperatures
Ok       : Voltages
Ok       : Hardware Log
Ok       : Batteries

For further help, type the command followed by -?

[root@somewhere ~]#
