Managing Serviceguard Eighteenth Edition, September 2010

The cluster must be running, and if the package is dependent on other packages, those
packages must be either already running, or started by the same command that starts
this package (see the section that follows, and “About Package Dependencies”
(page 179).)
Starting a Package that Has Dependencies
Before starting a package, it is a good idea to use the cmviewcl command to check for
package dependencies.
You cannot start a package unless all the packages that it depends on are running. If
you try, you’ll see a Serviceguard message telling you why the operation failed, and
the package will not start.
If this happens, you can repeat the run command, this time including the package(s)
this package depends on; Serviceguard will start all the packages in the correct order.
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. For example, to start 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.
Starting the Special-Purpose CVM and CFS Packages
Use CFS administration commands to start the special-purpose multi-node packages
used with 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 want to bring the package out of use but
want the node to continue running in the cluster. You can halt a package using
Serviceguard Manager or on the Serviceguard command line.
Halting a package has a different effect from 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.
