Log in to the primary domain.

Execute the ldm list-rsrc-group command to display the properties of the CMIOUs that are installed in the server.

# ldm list-rsrc-group -l

Note - In the default factory configuration, all of the cores are assigned to the primary domain. You must remove cores from the primary domain to assign them to new logical domains.

The following example for a SPARC M8 server shows the cores assigned to the primary domain before any logical domains have been created. The output has been edited for clarity.

# ldm ls-rsrc-group -l

The following example for a SPARC M7 server shows the cores assigned to the primary domain and two guest domains, ldm0 and ldm1:

# ldm list-rsrc-group -l

The IO column shows 5 for the SPARC M8 server and 4 for the SPARC M7 server because the eUSB device is attached to the root complex of the M8 CMIOUs.
