|Oracle Solaris Cluster Data Service for Oracle VM Server for SPARC Guide Oracle Solaris Cluster 4.0|
This section contains the information you need to plan your HA for Oracle VM Server installation and configuration.
Observe the following configuration guidelines that apply only to HA for Oracle VM Server.
For guidelines, requirements, and restrictions that apply to all data services, see the Oracle Solaris Cluster 4.0 Release Notes.
HA for Oracle VM Server configuration –Oracle VM Server for SPARC can be configured only as a failover data service and not as a scalable data service.
HA for Oracle VM Server virtual disks – The Oracle VM Server for SPARC virtual disk back end can be of any storage or file system that is supported by Oracle Solaris Cluster software. This includes cluster file systems, NFS, iSCSI, and SAN LUNs. The back end is exported through the virtual disk server to a domain as a full disk and is visible to the Oracle Solaris installation software inside the guest domain.
Live migration and warm migration – HA for Oracle VM Server software supports Oracle VM Server for SPARC live migration and warm migration. For more information, see your Oracle VM Server for SPARC documentation.
The failure policy settings on the primary domain determine the action to be taken on the guest domain when there is a primary domain failures. When configured to failure-policy=reset, the guest domain would panic when the primary domain fails. If the failure policy is not set to reset on all the primary domains, the resource creation would fail.
