Example 3–20 shows output from the show config command for a partition made up of
four QBBs. Callouts in the example are used to highlight a few features of the show
config command that can help you keep track of hardware and partitions.
This line shows both the hard and soft QBB ID number. In this case they happen
to be the same. However, had the partition been made up of QBBs 6 and 7, soft
QBB0 would have been hard QBB6 and soft QBB1 would have been hard QBB7.
The local links are equivalent to local I/O risers in QBBs. Each QBB may have up
to four. IOR numbering, however, follows a numbering scheme that combines hard
and soft numbers. In this example QBB0 has only one local I/O riser (local links 0
and 1) and two IORs 0 and 1. QBB1 has two local I/O risers (local links 0 – 3) and
four IORs 4 – 7. Note that IORs 2 and 3 are missing since a second local I/O riser is
missing in QBB0. Also note that the IOR numbering follows soft numbers. Had
the partition been made up of QBBs 6 and 7, IOR numbers could have been 0 – 7.
Finally, note that PCI hose numbers (different PCI buses) are always hard. This is
extremely helpful in following the hardware. A GS320 can have as many as 64 PCI
buses designated as hoses. Each QBB can control up to eight buses. QBB0
connects to Hoses 0-7, QBB1 to hoses 8-15, … QBB7 to hoses 56-63. Further, each
local link connects to hoses. Local link 0 controls the first two hoses in the group of
eight, local link 1 the next two and so on. You can mathematically figure out how
hoses connect by the formula QBB# * 8 + local link # * 2 = the first of two hose
numbers. Plugging in the numbers for QBB2, local link 2, you get hoses 20 and 21.
This holds true in show config across partitions. So for hard QBB6 local link 1,
the hoses are 50 and 51. You can trace the cable from the local I/O riser connected
to port 1 in QBB6 to the PCI box that contains buses 50 and 51.
