node as soon as the primary node is capable of running
the package and, if MIN_PACKAGE_NODE has been
selected as the Package Failover Policy, the primary
node is now running fewer packages than the current
node.
NODE_NAME The names of primary and alternate nodes for the
package. Enter a node name for each node on which the
package can run.
The order in which you specify the node names is
important. First list the primary node name, then the
first adoptive node name, then the second adoptive
node name, followed, in order, by additional node
names. in a failover, control of the package will be
transferred to the next adoptive node name listed in
the package configuration file.
If all nodes in the cluster are to be used, and if order is
not important, you can specify: NODE_NAME *
A node name can be up to 39 characters long.
AUTO_RUN If Automatic Switching is enabled (AUTO_RUN set to
YES), Serviceguard will automatically start the package
on an eligible node if one is available, and will
automatically fail the package over to another node if it
fails. If Automatic Switching is Disabled (AUTO_RUN set
to NO), Serviceguard cannot automatically start the
package up; you must do it manually using the
cmrunpkg command.
When a package starts up, the Package Switching flag
is set to match the AUTO_RUN setting, but you can
change this flag temporarily while the package is
running by means of the cmmodpkg command.
Default is YES.
LOCAL_LAN_FAILOVER_ALLOWED
Enter YES or NO. In the event of a failure, this permits
Serviceguard to transfer the package IP address to a
standby LAN card. The default is YES.
