Managing Serviceguard Sixteenth Edition, March 2009

NOTE: Any form of the mount command other than cfsmount or cfsumount should
be used with caution in a CFS environment. 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>
Resetting the Service Restart Counter
The service restart counter is the number of times a package service has been
automatically restarted. This value is used to determine when the package service has
exceeded its maximum number of allowable automatic restarts.
When a package service successfully restarts after several attempts, the package manager
does not automatically reset the restart count. You can reset the counter online using
the cmmodpkg -R -s command. For example:
cmmodpkg -R -s myservice pkg1
The current value of the restart counter is shown in the output of cmviewcl -v.
Allowable Package States During Reconfiguration
In many cases, you can make changes to a package’s configuration while the package
is running. The table that follows shows exceptions — cases in which the package must
not be running, or in which the results might not be what you expect — as well as
differences between modular and legacy packages.
