9.3.2 Configuration Parameters for Sun Cluster HA for Tivoli

This section describes the information you supply to the hadsconfig(1M) command to create configuration files for Sun Cluster HA for Tivoli. The hadsconfig(1M) command uses templates to create these configuration files. The templates contain some default, some hard coded, and some unspecified parameters. You must provide values for those parameters that are unspecified.

The fault probe parameters, in particular, can affect the performance of Sun Cluster HA for Tivoli. Tuning the probe interval value too low (increasing the frequency of fault probes) might encumber system performance, and also might result in false takeovers or attempted restarts when the system is simply slow.

Configure Sun Cluster HA for Tivoli by supplying the hadsconfig(1M) command with parameters listed in Table 9-1.
