HP Serviceguard A.11.20- Managing Serviceguard Twentieth Edition, August 2011

To create the CVM disk group or CFS mount point multi-node packages on systems that support
CFS, see “Creating the Disk Group Cluster Packages” (page 203) and “Creating a File System and
Mount Point Package” (page 216).
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
legacy packages, use cfscluster, cfsdgadm, or cfsmntadm. 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. To delete modular packages,
use cmhaltpkg and cmdeleteconf commands.
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 cfs commands. All the packages that depend on the multi-node package must be halted
on that node.
To remove the legacy CVM disk groups and CFS mount points, follow these steps:
CAUTION: You must not use the HP-UX mount and umount commands in a CFS environment;
use cfsmount or cfsumount for legacy CFS packages. For modular packages, you must use
cmcheckconf, cmapplyconf, cmrunpkg, cmmodpkg, and cmrunpkg. Non-CFS commands
(for example, mount -o cluster, dbed_chkptmount, or sfrac_chkptmount) could cause
conflicts with subsequent operations on the file system or Serviceguard packages, and will not
create an appropriate multi-node package, with the result that cluster packages are not aware of
file system changes.
1. Remove any dependencies on the package being deleted. Delete dependency_ parameters
from the failover application package configuration file, then apply the modified configuration
file:
cmapplyconf -v -P app1.conf
2. Unmount the shared file system
cfsumount <mount point>
3. Remove the mount point package from the cluster
cfsmntadm delete <mount point>
This disassociates the mount point from the cluster. When there is a single volume group
associated with the mount point, the disk group package will also be removed
4. Remove the disk group package from the cluster. This disassociates the disk group from the
cluster.
cfsdgadm delete <disk group>
