cmcheckconf -v -C /etc/cmcluster/verify.ascii
The cmcheckconf command checks:
• The network addresses and connections.
• The cluster lock disk connectivity.
• The validity of configuration parameters of the cluster and packages
for:
— The uniqueness of names.
— The existence and permission of scripts.
It doesn’t check:
• The correct setup of the power circuits.
• The correctness of the package configuration script.
Using the cmscancl Command
The command cmscancl displays information about all the nodes in a
cluster in a structured report that allows you to compare such items as
IP addresses or subnets, physical volume names for disks, and other
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:
