Resource Management API

The Resource Management API (RMAPI) provides a set of low-level routines that enable a data service to access information about the resources, resource types and resource groups in the system, request a local restart or failover, and set the resource status. You access these functions through the library. The RMAPI provides these callback methods both in the form of shell commands and in the form of C functions. See scha_calls(3HA) and Chapter 4, Resource Management API Reference for more information on the RMAPI routines. Also see Chapter 5, Sample Data Service for examples of how to use these routines in sample data service callback methods.
