In addition to providing automatic service failover, a cluster enables administrators to cleanly stop a service on one cluster system and then start it on the other cluster system. This service relocation functionality allows administrators to perform maintenance on a cluster system while maintaining application and data availability.
To relocate a service by using the cluadmin utility, invoke the service relocate command. For example:
cluadmin> service relocate nfs1 |
If a specific service is not designated, then a menu of running services will appear to choose from.
If an error occurs while attempting to relocate a service, a useful diagnostic approach would be to try to disable the individual service and then enable the service on the other cluster member.
