PreviouslyPublishedAs 202571
Applies to:Sun Fire 12K ServerSun Fire 15K Server Sun Fire E20K Server Sun Fire E25K Server All Platforms GoalThis document describes how to decode a Solaris[TM] Operating System device path to a physical location or slot, in an I/O board on a Sun Fire[TM] 12K/15K/E20K/E25K platform.SolutionHere is an example of an I/O device path as reported by Solaris OS: /pci@5c,700000/pci@1/SUNW, isptwo@4/sd@5,0
/\ /\ /\ Agent ID Offset Slot
Below is a diagram of the I/O board, labeling the IO slots: ____________Example: /pci@11d,600000/pci@1/SUNW...
11d is the Agent ID. Using the table in step 1, 11d maps to Expander 8, IOC 1. In step 2, the offset is 600000. Using the step 2 table, an offset of 600000 with an IOC of 1 maps to slot 2. Finally, referencing the slot diagrams, this device path equates to a card located on EXB 8, slot 2, the bottom left IO slot on the board. Warning: the hsPCI+ IO-board has an extra PCI bridge-chip to get to slot1. See Document 1006575.1 for details on what this means for your device path.
