Serviceguard Commands
Appendix A356
cmmodnet Add or remove an address from a high availability
cluster.
cmmodnet is used in the high availability package
control scripts to add or remove an IP_address
from the current network interface running the
given subnet_name.
Extreme caution should be exercised when
executing this command outside the context of the
package control script. In this capacity it should
only be used to remove the relocatable IP addresses
of packages which have failed and are in the
“halted” state. Use while the package is running
could lead to loss of client connectivity.
cmmodpkg Enable or disable switching attributes for a high
availability package.
cmmodpkg enables or disables the ability of a
package to switch to another node upon failure of
the package, and it enables or disables a particular
node from running specific packages. Switching for
a package can be enabled or disabled globally. For
example, if a globally disabled package fails, it will
not switch to any other node, and if a globally
enabled package fails, it will attempt to switch to
the first available node on which it is configured to
run.
