• To receive notifications about the status change of the Remote Copy Volume Groups,
specify an appropriate value for the DR_NOTIFICATION_CHOICES attribute by
specifying one or more notification types.
The DR_NOTIFICATION_CHOICES attribute supports the following types of
notifications:
◦ EMAIL
NOTE: For email notifications, you must include sg/email module as part of
the package.
◦ SYSLOG
◦ OPC
◦ CONSOLE
You can configure one or any combination of the notification types for the Remote Copy
Volume Group monitor in the DR_NOTIFICATION_CHOICES attribute. For example, to
configure all the types of notifications:
DR_NOTIFICATION_CHOICES EMAIL OPC SYSLOG CONSOLE
If you do not want to use the Remote Copy Volume Group monitor, comment the
DR_NOTIFICATION_CHOICES attribute and the monitoring service in the package
configuration file.
For the failover_policy parameter, in Metrocluster failover packages you can use any
of the Serviceguard defined failover policies. The site_preferred and
site_preferred_manual failover policies are introduced in Serviceguard specifically for
Metrocluster configurations.
The site_preferred value implies that when a Metrocluster package needs to fail over, it
fails over to a node in the same site as the node it last ran. If a configured node is not available
within the same site, the package fails over to a node on another site.
The site_preferred_manual failover policy enables automatic failover of packages within
a site and manual failover across sites.
Configure a cluster with sites to use either of these policies. For information on configuring
the failover policy to site_preferred or site_preferred_manual, see “Site Aware
Failover Configuration” (page 10).
3. Validate the package configuration file.
# cmcheckconf -P pkgName.config
4. Apply the package configuration file.
# cmapplyconf -P pkgName.config
NOTE: After the modular Metrocluster 3PAR package is created, if the value of any
Metrocluster 3PAR parameter needs to be changed, then edit this package configuration file
and re-apply it.
Online reconfiguration of the packages
Metrocluster with 3PAR Remote Copy for Linux supports the online reconfiguration of the packages.
