You can specifically include or exclude IP addresses individually for discovery or as part of a range. IP address range entries also affect cluster discovery. The IP ranges must include the addresses of the cluster and its nodes. Enter one system or range per line. Use the following guidelines:

IP RangeRange to Enter

Your local subnet IP ranges from 1 to 254, the default Ping inclusion ranges

172.25.76.1-172.25.76.254

A single system as a range in the Ping inclusion ranges or Exclusion ranges fields

172.25.76.114-172.25.76.114 or 172.25.76.114

A group of systems within a subnet in the Ping inclusion ranges or Exclusion ranges fields

172.25.76.38-172.25.76.48

Systems included in a discovery template file

@DiscoveryTemplate_filename

Systems included in a hosts file

$filename

No broadcast node in this subnet

172.25.76.255:NOBROADCAST

Broadcast node determined by the subnet mask

172.25.76.0-172.25.76.255:255.255.255.0 or 172.25.76.114:255.255.255.0

Discovery assumes you do not want to ping the subnet network ID, typically the zero node, or the subnet broadcast address, typically node 255, because these would unnecessarily take network resources. If the system 255 is not a broadcast address on your network, you can indicate this in the Ping inclusion ranges section as shown in the table or exclude the specific system in the Exclusion ranges section. HP Systems Insight Manager (HP SIM) uses the subnet mask to determine the broadcast system. If you do not specify a mask, HP SIM uses the default mask for the class of network. If your subnet mask is not the default for the class, the broadcast system can be included, generating much more network traffic than necessary.
