Managing HP Serviceguard A.12.00.00 for Linux, June 2014

Table 12 Types of Changes to Packages (continued)
Required Package StateChange to the Package
Package can be running. See “Online Reconfiguration of serviceguard-xdc
Modular Package Parameters” (page 110).
Change modular serviceguard-xdc
package parameters:
xdc/xdc/rpo_target
xdc/xdc/raid_monitor_interval
xdc/xdc/raid_device
xdc/xdc/device_0
xdc/xdc/device_1
Package can be running.
NOTE: Do not include the email module in the modular package. The
serviceguard-xdc and toolkit packages automatically includes the email module
in the modular package.
Add, change, or delete an email
attribute
NOTE: Consider a configuration in which the volume group and the corresponding filesystem
are present in two different packages. To perform online reconfiguration of such packages, the
package with the volume group must be reconfigured before you reconfigure the filesystem package.
HP recommends that you do not perform online reconfiguration for both these packages in a single
command as it might cause one or more packages to fail.
7.7.7.1 Changes that Will Trigger Warnings
Changes to the following will trigger warnings, giving you a chance to cancel, if the change would
cause the package to fail.
NOTE: You will not be able to cancel if you use cmapplyconf -f.
• Package nodes
• Package dependencies
• Package weights (and also node capacity, defined in the cluster configuration file)
• Package priority
• auto_run
• failback_policy
7.7.8 Online Reconfiguration of Modular package
To modify the configuration of modular package while the package is up and running:
1. Obtain a copy of the package configuration file, if it is not already available:
#cmgetconf -p pkg1 pkg1.conf
2. Edit the package configuration file.
3. Verify the package configuration changes:
#cmcheckconf -v -P pkg1.conf
4. Apply the changes to the configuration:
#cmapplyconf -v -P pkg1.conf
Once the cmapplyconf command succeeds, verify the following:
a. Any failures logged in syslog and package log files.
b. If for some reason the online package reconfiguration fails, the Serviceguard sets the
online_modification_failed flag to "yes". Verify the flag status using cmviewcl
-f line output.
