A new subsystem has been added for multi-domained systems, such as SPARC M5-32 and M6-32 servers:

dcu - Show details of dcu subsystem.

For SPARC M5-32 and M6-32 systems, open_problems diagnosed by Oracle ILOM are not reported by hwmgmtcli on PDOM hosts. In addition, health, and health_details information might be missiing or not reliable.

On multi-domain systems hwmgmtcli can only see the devices (such as controllers and storage) that are dedicated to the host domain where hwmgmtcli is being run. In contrast, Oracle ILOM obtains reports from all domains and therefore can report on all devices in the system.
