Configuring Dell OpenManage IT Assistant to Monitor Your Systems 87
In her small-to-medium size network, Jane must install, enable, and configure
CIM to be able to manage client systems running the latest Client
Instrumentation (OMCI 7.x). Although Tom’s group of managed systems are
made up entirely of servers, he will also install and enable CIM. Generally,
CIM should be enabled if your enterprise includes any managed system
running a Microsoft Windows operating system.
NOTE: Dell OpenManage Server Administrator only sends events to IT Assistant as
SNMP traps. It does not send CIM indications for either instrumentation or storage
events from a server.
Configuring CIM in the Operating System
IT Assistant uses the Windows Management Interface (WMI) core to make
CIM connections. The WMI core uses Microsoft network security to protect
CIM instrumentation from unauthorized access.
For more information on operating system CIM configuration, see "Setting
Up CIM."
NOTE: IT Assistant requires the CIM user name and password with administrator
rights that you established on the managed systems. If you are using a domain user,
be sure to specify the correct domain in the user name field. A user name must
always be qualified with a domain, or localhost if a domain is not present.
The format is either <domain>\<user> or <localhost>\<user>.
NOTE: CIM discovery requires proper user ID and password credentials. Failure to
supply proper credentials on a subnet configured for CIM discovery can result in
account lockout.
Best Practices for Setting Up Discovery Targets
Regardless of the size of your network, the following table shows Dell’s
recommendations for the best way to set up discovery targets. IT Assistant
users define discovery target systems and ranges on a network to identify the
systems that they want to locate and record in their database. When you set
up a discovery target and range in IT Assistant, you are given the option of
selecting a host name, an IP address, or a subnet range to identify the systems
that you want IT Assistant to discover. This section shows which discovery
type is best for the network environment you have.
