Understanding PCIe Card Device and Service Paths
Understanding PCIe Card Device and Service Paths
Every slot location has three unique methods of identification:
■
A physical location consists of the CMIOU number and the PCIe slot.
■
The device path is how the Oracle Solaris hotplug command identifies a slot location.
■
The service path is how the Oracle ILOM show command identifies a slot location.
■
The BUS name is the value you supply to assign a root complex to a logical domain.
Note - In half-populated configurations, PCIe slots are unused for an empty CMIOU slot.
These topics list the PCIe card paths for each CMIOU chassis in the server.

PCIe Card Paths (Bottom CMIOU Chassis)
These are the CMIOU numbers, device paths, and service paths for each PCIe card slot in the
SPARC M8-8 server, the SPARC M7-8 server, and the SPARC M7-16 server bottom CMIOU
chassis.
