The progress window shows messages as the action takes place. This will
include messages for starting the package.
The cluster must be running in order to start a package.
Using Serviceguard Commands to Start a Package
Use the cmrunpkg command to run the package on a particular node,
then use the cmmodpkg command to enable switching for the package.
Example, for a failover package:
# cmrunpkg -n ftsys9 pkg1
# cmmodpkg -e pkg1
This starts up the package on ftsys9 , then enables package switching.
This sequence is necessary when a package has previously been halted
on some node, since halting the package disables switching.
Use the cfs admin commands, listed in Appendix A, to start the
special-purpose multi-node packages used with CVM and CFS. For
example, to start the special-purpose multi-node package for the disk
group package (SG-CFS-DG-
id# ), use the cfsdgadm command. To start
the special-purpose multi-node package for the mount package
(SG-CFS-MP-
id# ) use the cfsmntadm command. Check to see if your
package has a dependency; before you can start your dependent package,
you must start all the packages it depends on.
Halting a Package
You halt a Serviceguard package when you wish to bring the package out
of use but wish the node to continue in operation. You can halt a package
using Serviceguard Manager or on the Serviceguard command line.
Halting a package has a different effect than halting the node. When you
halt the node, its failover packages may switch to adoptive nodes
(assuming that switching is enabled for them); when you halt a failover
package, it is disabled from switching to another node, and must be
restarted manually on another node or on the same node.
System multi-node packages run on all cluster nodes simultaneously;
halting these packages stops them running on all nodes. A multi-node
package can run on several nodes simultaneously; you can halt them on
all the nodes where they are running, or you can specify individual
nodes.
