Cluster and Package Maintenance
Reconfiguring a Package
Chapter 7276
Allowable Package States During Reconfiguration
In many cases, you can make changes to a package’s configuration while
the package is running. Table 7-2 shows exceptions - cases in which the
package must not be running, or in which the results might not be what
you expect.
Parameters not listed in the table can be changed 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 by Table 7-2.)
NOTE All the nodes in the cluster must be powered up and accessible when you
make package configuration changes.
