You can view the DCU properties on the DCUs page in the Oracle ILOM web interface.
For a SPARC M8-8 or SPARC M7-8 server with two PDomains, you should see output similar to this:
-> show /System/DCUs/ /System/DCUs Targets: DCU_0 DCU_1 Properties: health = OK health_details = - installed_dcus = 2 max_dcus = 2 dcu_size = 4 failover = auto ... ->
For a SPARC M8-8 or SPARC M7-8 server with one PDomain, you should see output similar to this:
-> show /System/DCUs/ /System/DCUs Targets: DCU_0 Properties: health = OK health_details = - installed_dcus = 1 max_dcus = 1 dcu_size = 8 failover = auto
For the SPARC M7-16 server, you should see output that is similar to this:
-> show /System/DCUs/ /System/DCUs Targets: DCU_0 DCU_1 DCU_2 DCU_3 Properties: health = OK health_details = - installed_dcus = 4 max_dcus = 4 dcu_size = 4 failover = auto
The output of this command depends on the server model.
This example shows the output from a SPARC M7-8 server with four CMIOUs installed in DCU_0.
