About configuring VCS for Oracle VM Server for SPARC with multiple I/O domains
With Oracle VM Server for SPARC virtualization technology, you can create multiple I/O domains, a control domain and an alternate I/O domain, to provide redundant storage and network services to a guest Logical Domain. A typical cluster setup that is configured to use multiple I/O domains has two physical systems. On each physical system, the control domain and alternate I/O domain provide I/O services from back-end storage and network devices to a Logical Domain.
Figure: with guest Logical Domain on System A and System B using storage and network services from the control domain and alternate I/O domain
If there is a storage or a network service failure from one of the domains, the guest Logical Domain continues to function on the same physical system because it gets the I/O services from the other I/O domain. However, when there is failure of services from both the I/O domains on a physical system, the Logical Domain on the physical system fails.
Configure Cluster Server (VCS) on multiple I/O domains to manage a Logical Domain. VCS fails over the Logical Domain from one system to a Logical Domain on another system when services from both the domains fail.
Note:
Failover happens when I/O services from all I/O domains fail or the control domain goes down.
