Metrocluster with Continuous Access XP Version A.11.00 Release Notes, August 2010 (B8109-90027)

Support for HP Integrity Virtual Machines 4.2
Metrocluster with Continuous Access XP version A.11.00 includes support for HP
Integrity Virtual Machines 4.2. All Serviceguard-related restrictions and guidelines for
supporting HP Integrity Virtual Machines 4.2 are also applicable for Metrocluster
configurations.
Following are a few additional guidelines for Metrocluster configurations:
• HP Virtual Machine guests cannot be configured as a node in a Metrocluster.
• To migrate the HP Virtual Machine guest online, use the hpvmsg_move command.
• Metrocluster does not support online VM guest migration when the source node
and the target node are in different sites. Metrocluster supports online guest
migration only when the source node and the target node are in the same site.
For more information on configuring HP Integrity Virtual Machines with Metrocluster,

Support for Serviceguard A.11.20
Starting with this release, Metrocluster with Continuous Access XP supports HP
Serviceguard Version A.11.20. All configuration restrictions that apply to HP
Serviceguard also apply to Metrocluster.
IMPORTANT:
• The easy deployment feature is not supported for deployment of Metrocluster.
• Live Application Detach feature is not supported in SADTA environment.
• Serviceguard Package Maintenance mode is not supported for Site Controller
packages and for the packages managed by the Site Controller package.
• In a Metrocluster environment, the cmeval tool cannot be used to evaluate the
replication status and the changes to the environment file. In SADTA, the cmeval
tool cannot be used to evaluate the Site Controller package operations.
• Online package re-configuration of Site Controller module parameters is not
supported.
Manual Site Switching
Starting with this release, Metrocluster with Continuous Access XP supports a new
Serviceguard failover policy: site_preferred_manual, introduced in HP
Serviceguard Version A.11.20. This failover policy prevents automatic failover of a
package across SITEs. This failover policy can be used for Site Controller packages and
failover packages configured in a Metrocluster with sites defined in the Serviceguard
cluster configuration file.
