Solution Type Technical Instruction Sure Solution 1003932.1 : Physical device mapping for PCI-X I/O Boards (Sun Fire[TM] 4800, E4900, 6800, E6900) and PCI-X IB_SSC (Sun Fire[TM] v1280, E2900 and Sun Netra[TM] 1280, 1290).
PreviouslyPublishedAs 205509 Description The document describes the physical IO device mapping for the Serengeti PCI-X IO Assembly and the LW8 PCI-X IB_SSC Assembly. This will be handy while decoding Solaris[TM]/OBP device-paths to their physical device slot. Steps to Follow Physical device mapping information. Sun Fire[TM] 4800, E4900, 6800, and E6900 PCI-X I/O Layout:
where "xx" in column Device Path Address is the AID (XMITS Agent ID). See example below to understand a typical device path in Solaris/OBP : /ssm@0,0/pci@1e,700000/pci@1/network@1" ^ ^^ ^ ^ Node Id __________| | | |________ PCI Device # | | AID |________Bus/Leaf # (A=600000 or B=700000) To decode the above path, follow the AID layout as per Infodoc 27432 To locate IO board number, divide AID by 2 and subtract 6. Note that the AID is in HEX. Hex: (1e/2) - 6 = 9 Alternately - Hex 0x1e = Decimal 30 thus (30/2) - 6 = 9 The result tells us that the device resides on I/O boat in slot 9 (IB9). The even numbered AID indicates XMITS0(whereas an odd number AID would indicate XMITS1), "700000" indicates leaf B and PCI device # 1 indicates that this is PCI slot 0 in IB9. Note :
Sun Fire[TM] V1280, E2900 PCI-X IB_SSC Assembly Layout:
