The SPARC M8-8 and SPARC M7-8 servers support either two static PDomains or one static PDomain. You cannot reconfigure static PDomains. However, you can administer CMIOUs and DIMMs, and use domain-level commands to administer and monitor the components within a static PDomain.
The SPARC M7-16 server supports one to four dynamic PDomains that you can reconfigure. You can also administer and monitor the components within those PDomains.
Each PDomain is represented as /Servers/PDomains/PDomain_n in Oracle ILOM, where n ranges from zero to one less than the maximum number of possible PDomains.
Each DCU is represented as /System/DCUs/DCU_n in Oracle ILOM, where n ranges from zero to one less than the maximum number of possible DCUs.
