Managing HP Serviceguard for Linux Ninth Edition, April 2009

Resetting the Service Restart Counter
The service restart counter tracks 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
cmmodpkg -R -s, for example:
cmmodpkg -R -s myservice pkg1
This sets the counter back to zero. The current value of the restart counter appears 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.
In general, you have greater scope for online changes to a modular than to a legacy
package. In some cases, though, the capability of legacy packages has been upgraded
to match that of modular packages as far as possible; these cases are shown in the table.
For more information about legacy and modular packages, see Chapter 6 (page 189).
NOTE: If neither legacy nor modular is called out under “Change to the Package”, the
“Required Package State” applies to both types of package. Changes that are allowed,
but which HP does not recommend, are labeled “should not be running”.
IMPORTANT: Actions not listed in the table can be performed for both types of package
while the package is running.
In all cases the cluster can be running, and packages other than the one being
reconfigured can be running. And remember too that you can make changes to package
configuration files at any time; but do not apply them (using cmapplyconf or
Serviceguard Manager) to a running package in the cases indicated in the table.
