You can use the ldm command to store the current configuration of a logical domain on the service processor. You can add a configuration, specify a configuration to be used, remove a configuration, and list the configurations. For details, see the ldm(1M) man page. You can also specify a configuration to boot from the SP, as described in Using Oracle VM Server for SPARC With the Service Processor.
For information about managing configurations, see Managing Domain Configurations.
