SFHA Solutions 6.2 (Solaris): Dynamic application failover in a virtual environment
The AdaptiveHA feature was introduced in Storage Foundation and High Availability (SFHA) 6.1. Beginning in this release, Symantec Cluster Server (VCS) supports dynamic selection of target nodes for a virtual machine service group (VMSG). In this release, this feature is supported only on Oracle VM Server for SPARC. When you install VCS, this feature is enabled by default.
In a VMSG, you do not need to include CPU, Memory, and Swap values when specifying the Load because the Load is auto-populated by aggregating resource utilization. VCS monitors and forecasts the available capacity of the physical server in terms of SCPU and SMem. SCPU and SMem are resource-level meters. If you set the FailOverPolicy service group attribute to BiggestAvailable, VCS dynamically selects the biggest available target physical server to bring the VMSG online, or switch or failover the VMSG.
