6 Systems Management using Dell OpenManage
6.1 Dell Systems Management
OpenManage Server Administrator (OMSA) is a comprehensive systems management tool
for PowerEdge servers. It provides easy-to-use management and administration of local
and remote systems through a set of integrated management services. OMSA resides solely
on the system being managed and is accessible both locally and remotely. Dell OMSA
agent can be installed inside the Domain0, that is based on CenOS4 distribution.
Dell IT Assistant (ITA) is a comprehensive and standards-based console for managing all
Dell servers, storage, tape libraries, network switches, printers and clients systems. Among
many features, ITA provides administrators with ability to:
• Have web-based one-view console for Dell systems with red, yellow and green
status indication
• Capture events and alerts generated by Dell servers running OMSA
• Configure actions based on events and alerts
• Monitor server performance statistics such as CPU, memory, I/O, etc.
6.2 Dell OMSA Install
This section describes the steps necessary to install OMSA agent inside XenEnterprise 3.2
Domain0. For the purpose of these steps, OpenManage 5.2 was used. Please note that
OMSA is not supported by Dell inside a CentOS distribution as Dell has not tested OMSA
in this environment. The below steps are provided to enable customers to manage
XenEnterprise hosts, without any implied support or warranty.
1. Download the Dell OpenManage Server Administrator Managed Node software
package for RedHat Enterprise Linux 4 from http://support.dell.com
2. Copy the tar.gz file to the XenEnterprise host.
3. Extract the tar.gz file by using the command
$ tar -zxvf yourfilename.tar.gz
4. Edit the setup script to enable installation on XenEnterprise server:
a. First, change the permissions of the setup.sh script to make it writeable:
$ chmod +w setup.sh
b. Then, edit the file:
$ vi setup.sh
c. Then, go to line 2976 and change the following lines
# Set default values for return variables.
GBL_OS_TYPE=${GBL_OS_TYPE_UKNOWN}
GBL_OS_TYPE_STRING="UKNOWN"
to
# Set default values for return variables.
GBL_OS_TYPE=${GBL_OS_TYPE_RHEL4}
GBL_OS_TYPE_STRING="RHEL4"
