Take a look at what is new for this release.
Cluster administrative domain support
A cluster
administrative domain monitors and synchronizes changes to selected
resources within a cluster. Cluster administrative domain provides easier
management and synchronization of attributes for resources that are shared
within a cluster, such as environment variables or user profiles. For more
information about cluster administrative domain, see these topics:
Peer cluster resource group (CRG) support
All CRG
interfaces have been enhanced to support peer cluster resource group (CRG).
A peer cluster resource group (CRG) is a non-switchable CRG in
which each node in the recovery domain has an equal role in the recovery of
the resources associated with the peer CRG. For more information, see the
following topics:
Cluster enhancements
Several enhancements have been
made to improve powering down operations and problem resolution within a clustered
environment. These improvements include:
- A systematic approach to end clustering on a cluster node when all active subsystems are ended, or when the system is ended or powered down. See How a system event affects a cluster for details.
- The capability to configure a new application CRG with an active takeover IP address. See Create an application CRG with an active takeover IP address for more information.
- The capability to troubleshoot cluster problems by viewing an entire cluster and its associated CRGs from an active node. See Gather recovery information for a cluster for more details.
- New information about debug tools and the results they generate has been added. You can use these tools and their results to determine the resolution of a problem within a cluster. See the following topics for more details:
