node-specific items for all nodes in the cluster. cmscancl actually runs
several different HP-UX commands on all nodes and gathers the output
into a report on the node where you run the command.
To run the cmscancl command, the root user on the cluster nodes must
have the .rhosts file configured to allow the command to complete
successfully. Without that, the command can only collect information on
the local node, rather than all cluster nodes.
The following are the types of configuration data that cmscancl displays
for each node:
Using the cmviewconf Command
cmviewconf allows you to examine the binary cluster configuration file,
even when the cluster is not running. The command displays the content
of this file on the node where you run the command.
Reviewing the LAN Configuration
The following networking commands can be used to diagnose problems:
• netstat -in can be used to examine the LAN configuration. This
command lists all IP addresses assigned to each LAN interface card.
