2.6.1 Service and Application Restrictions

Note the following restrictions related to services and applications.

• Sun Cluster can be used to provide service for only those data services that either are supplied with Sun Cluster or set up using the Sun Cluster data services API.

• Do not configure the Sun Cluster nodes as mail servers, because sendmail(1M) is not supported in a Sun Cluster environment. No mail directories should reside on Sun Cluster nodes.

• Do not configure Sun Cluster systems as routers (gateways). If the system goes down, the clients cannot find an alternate router and recover.

• Do not configure Sun Cluster systems as NIS or NIS+ servers. Sun Cluster nodes can be NIS or NIS+ clients, however.

• A Sun Cluster configuration cannot be used to provide a highly available boot or install service to client systems.

• A Sun Cluster configuration cannot be used to provide highly available rarpd service.
