Hardware paths on an rp8420?

[Kenneth Platz]

Hullo everyone,

We've got an rp8420 (actually a couple) with the optional expansion cabinet, and we're having some difficulty deciphering exactly where some of our I/O cards are physically located on the server. For example, we've got 3 LAN cards on the server, which are located at:

0/0/0/1/0 lan HP A7109-60001 PCI 1000Base-T Core
0/0/8/1/0/6/0 lan HP A9782-60001 PCI/PCI-X 1000Base-SX FC/GigE Combo Adapter
1/0/0/1/0 lan HP A7109-60001 PCI 1000Base-T Core

Ideally, if anyone has a drawing or description of how the hardware paths map on an rp8420, that'd be perfect. (Don't you miss the days where it was actually labelled on the back of the server?)

Hi there.
The two cards marked with core should be available on the mainboard.
The third looks lke an additional card.
You can check it with either stm / xtsm / cstm ( Support tool manager ) or do an
ioscan -fn into a file.

Hi,

you can get the HW path to Slot assignement with the command "olrad -q" (HPUX 11.23, for HPUX 11.11 it would be "rad -q")
On our rx7620 system I get:

# olrad -q
Driver(s)
Capable
Slot Path Bus Max Spd Pwr Occu Susp OLAR OLD Max Mode
Num Spd Mode
0-0-1-1 1/0/8/1 64 133 133 Off No N/A N/A N/A PCI-X PCI-X
0-0-1-2 1/0/10/1 80 133 133 Off No N/A N/A N/A PCI-X PCI-X
0-0-1-3 1/0/12/1 96 133 133 Off No N/A N/A N/A PCI-X PCI-X
0-0-1-4 1/0/14/1 112 133 133 Off No N/A N/A N/A PCI-X PCI-X
0-0-1-5 1/0/6/1 48 133 133 Off No N/A N/A N/A PCI-X PCI-X
0-0-1-6 1/0/4/1 32 133 133 Off No N/A N/A N/A PCI-X PCI-X
0-0-1-7 1/0/2/1 16 133 66 On Yes No Yes N/A PCI-X PCI
0-0-1-8 1/0/1/1 8 133 66 On Yes No No N/A PCI-X PCI

the slot 0-0-1-8 means for example Cabinet 0 (always 0 except Superdome) IO Bay 0 (always 0 except Superdome), I/O Chassis 1 (1 is right half, 0 is left half, is labeled), Slot 8 (is also labeled).

To be 100 % sure, you can turn on the attention LED of a card:

olrad -I ATTN 0-0-1-8

turn off with:

olrad -I OFF 0-0-1-8

read "man olrad" for more information including online addition and replacement.

In general you have the following assignement on rx7620, rx8620, rp7420, r08420:
(X is the Cellboard Number. Cell 0 connected to left half of the IO/Chassis, Cell 1 connected to right, Cells 2 and 3 can be connected to a SEU Expansion Chassis in the same manner.)

X/0/0/Y Core I/O (Y=0...3)
X/0/1/1 Slot 8
X/0/2/1 Slot 7
X/0/4/1 Slot 6
X/0/6/1 Slot 5
X/0/8/1 Slot 1
X/0/10/1 Slot 2
X/0/12/1 Slot 3
X/0/14/1 Slot 4

best regards

Your machine supports the online replacement commands. See this manual for help:

http://docs.fc.hp.com/cgi-bin/onlinedocs.py?mpn=B2355-90862&service=hpux&path=00/00/1&title=Interface%20Card%20OL*%20Support%20Guide

If you wonder if you have the right card / slot, you should be able to blink the attention LED on that slot for identification. This eliminates the guesswork.

The 'olrad' command already mentioned is key. If you are running 11.23, there is also a GUI front end called 'pdweb' that you may like also.

to add to stefan's answer, the IO bay can be '1' in non-superdomes when the Server Expansion Unit (which is an external I/O and Disk enclosure) is installed.

I also have an rp8420 with 3 lan:

lan0 0/0/0/1/0 HP A7109-60001 PCI 1000Base-T Core
lan1 1/0/0/1/0 HP A7109-60001 PCI 1000Base-T Core
lan2 1/0/10/1/0 HP A6825-60101 PCI 1000Base-T Adapter

I know which one the adapter lan is.

How do I find out which core lan is which? top or bottom?

rad -q doesn't tell me the core, only the adapter.

[Joshua Scott]

lan0 is Core I/O 0 (note the 0 at the beginning of the path)
