Cluster and Package Maintenance
Reconfiguring a Package

If this is a legacy package, remember to copy the control script to the
/etc/cmcluster/pkg1 directory on all nodes that can run the package.
To create the CFS disk group or mount point multi-node packages on
systems that support CFS, see “Creating the Disk Group Cluster
Packages” on page 248 and “Creating a Filesystem and Mount Point
Package” on page 249.
Deleting a Package from a Running Cluster
Serviceguard will not allow you to delete a package if any other package
is dependent on it. To check for dependencies, use cmviewcl -v -l
<package>. System multi-node packages cannot be deleted from a
running cluster.
You can use Serviceguard Manager to delete the package.
On the Serviceguard command line, you can (in most cases) delete a
package from all cluster nodes by using the cmdeleteconf command. To
delete one of the Veritas Cluster File System packages (on systems that
support CFS), use the cfscluster, cfsdgadm, or cfsmntadm command.
This removes the package information from the binary configuration file
on all the nodes in the cluster. The command can only be executed when
the package is down; the cluster can be up.
The following example halts the failover package mypkg and removes the
package configuration from the cluster:
cmhaltpkg mypkg
cmdeleteconf -p mypkg
The command prompts for a verification before deleting the files unless
you use the -f option. The directory /etc/cmcluster/mypkg is not
deleted by this command.
On systems that support CFS, you can remove nodes from a multi-node
package configuration using the cfs commands listed in Appendix A.
All the packages that depend on the multi-node package must be halted
on that node.
To remove the CFS mount point and disk group packages, follow these
steps:
