PCI Card Slot and Hardware Path Numbering
On nPartition servers, the PCI card slot numbers (within an I/O chassis)
are not necessarily the same as their local bus adapter (LBA) number,
such as is reported by the ioscan or rad HP-UX commands.
Table 1-1 shows the correlations among PCI slots and their LBA
numbers.
For an example, issue the ioscan -C ba command to lists the PCI slots
(“Local PCI Bus Adapter”) for your partition.
The order in which ioscan reports the PCI slots (in LBA number order)
does not correspond to the order in which the slots physically are
arranged (PCI card slot order, left to right).
The rad -q command lists each active PCI slot, its associated HP-UX
hardware path, and other slot details.
