Specify the network name and network address of each MCP host system you want to manage from the server.
Define a list of network names and their network addresses.

network-address
is the Internet Protocol (IP) address number of the MCP host system.
network-name

Add an MCP host system that is to be managed to the Operations Sentinel network.
Change the network IP address of an MCP host system in the Operations Sentinel network.
Change the network name of an MCP host system in the Operations Sentinel network.
You must update the hosts file before the interface to the system that you wish to monitor can be initialized.
Note: Verify Configuration optionBefore attempting to use Operations Sentinel, you should execute the Verify Configuration facility of the Operations Sentinel to ensure that the contents of the hosts and services files on the Operations Sentinel server are consistent with the network data you specified in the configuration. You should also ensure that you can access the MCP system on the network.
