Physically slot place of NIC and FC

[itrc55]

Hi All,

i have a "superdome 2 16s" with 7 cells (with 3 servers), two iox and two interconect module. i have two questions about that.

1- How do I know a place of Ethernet and fiber cable physically on a server. ( i using the #olrad -q command on the rp8420 server but it's not working on a superdome 2)

2- How i can disable the fiber and Ethernet card (or HBA) by command on superdome 2 .

Thanks

Hi,

Try with rad -q command

please read the man page for the options to power off/power on the card, before power off suspend the operation on the card,

rad -s
rad -o

rad -i
rad -r

Thanks
Ravi S

hey itrc...

Since it's a superdome 2 {although I am no expert on SD2 servers }, there should be olrad support as well as OLD support and by that I mean Online Deletion.

How about

man olrad

Hi,

Thanks for your replay, but also the rad command is not working. when i use the olrad command i facing a message from a system "i don't remember it now".
but if is there any other method to i can know a place of Ethernet and fiber cable physically on a server. and How i can disable the fiber and Ethernet card (or HBA) by command on superdome 2

Very Thanks

Hi,

i still waiting answers for my questions.

How i can disable the Ethernet card (or HBA) by command on interconnect module superdome 2.

Thanks

[Torsten. · Accepted solution]

"olrad" is not yet working/available.

To find the HBA, use

# ioscan -m resourcepath


You will find the physical location in the right column.



To remove the HBA, power off the nPar or at least the vPar.

[Duncan Edmonstone]

As Torsten said, "ioscan - m resourcepath" is the key one here...

First use "ioscan -funC lan" to identify all the LAN ports on your system.

Now figure out which ioslot that LAN card is in by matching the HW path with those for the ioslots in the "ioscan - m resourcepath" output.

Hi,

yes i using the lanscan command to get the H/W path of my lan card and then matching with the "ioscan -m resourcepath" output.

but the problem i don't know how to disable the lan card port from procurve switch.

i can login to switch (GUI) but i don't work before on it.

Thanks

[Torsten.]

Do you talk about a card in the I/O chassis or about a LAN adapter directly on the blade itself?

Wha do you want to "disable" it?

Does in this case "disable" means remove???

Hi,

in my superdome 2 two iox and two hp procurve 6120xg blade switch. and 7 cell with 3 servers
(two vpar and one npar) i want to disconnect the cable physically of some server for cluster troubleshooting.
For that I using the lanscan command to get the H/W path of my lan card and then matching with the "ioscan -m resourcepath" output, To I can disable the port of the lan card from procurve 6120xg switch.
Thatâ s my story.

And thanks for your support.

[Torsten.]

Are the NICs in the IOX really connected to the procurve?

Maybe, but maybe not.


If you need help to find the slot of the HBA, consider to post the hardware path and the ioscan resourcepath output.

[itrc55]

Hi,

Are the NICs in the IOX really connected to the procurve ? sure no all the cards on IOX it's a fiber card and for combo card is nothing connected.

Thanks

[Torsten.]

What is the NIC in question?

lan2 / lan5 /lan6 or lan7 ????

[Duncan Edmonstone]

Ok, are you trying to figure out how the ports on the Procurve are matched up to the LOMs on the Superdome blades?

You can do this by logging into the OA on the command line and issuing the "SHOW INTERCONNECT PORT MAP ALL" command:

> SHOW INTERCONNECT PORT MAP ALL


1: HP ProCurve 6120XG Blade Switch
Type: Ethernet
Width: Single
Status: OK
Port 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Status OK OK OK OK OK OK OK OK
Blade 1 2 3 4 1 2 3 4
Mezz/Nic NI NI NI NI NI NI NI NI
Port 3 3 3 3 1 1 1 1

2: HP ProCurve 6120XG Blade Switch
Type: Ethernet
Width: Single
Status: OK
Port 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Status OK OK OK OK OK OK OK OK
Blade 1 2 3 4 1 2 3 4
Mezz/Nic NI NI NI NI NI NI NI NI
Port 4 4 4 4 2 2 2 2


From my ioscan:

#ioscan -funC lan | grep "Built-in"
lan 0 1/0/0/0/0/0/0 iexgbe CLAIMED INTERFACE HP PCIe 2-p 10GbE Built-in
lan 1 1/0/0/0/0/0/1 iexgbe CLAIMED INTERFACE HP PCIe 2-p 10GbE Built-in
lan 2 1/0/0/2/0/0/0 iexgbe CLAIMED INTERFACE HP PCIe 2-p 10GbE Built-in
lan 3 1/0/0/2/0/0/1 iexgbe CLAIMED INTERFACE HP PCIe 2-p 10GbE Built-in


So this is blade 2, so I know that for the 4 ports on blade 2:

lan0 goes to port 10 in the Procurve in interconnect bay 1
lan1 goes to port 10 in the Procurve in interconnect bay 2
lan2 goes to port 2 in the Procurve in interconnect bay 1
lan3 goes to port 2 in the Procurve in interconnect bay 2

I can't help you with the commands on a procurve to disable/enable a port though - I expect there's an easy web interface to use if you wish...

Hi,

Sorry, it's lan2 and lan5

Thanks

[Torsten.]

These NICs are on the blades itself, so see the previous post.


You can also "cut" the connection from the NIC to the interconnect bay by using the port assignment tab from the OA.

[Duncan Edmonstone]

So lan2 and lan5 appear to be LOM3 on blade 4 and LOM 4 on blade 6. I guess you will have the same port interconnect mapping as I have, so that translates into port 4 on interconnect 1 and port 6 on interconnect 2.

I just had a quick play with the Procurve switch GUI accessed via the OA, and enabling/disabling a port was pretty straightforward through its management console. Disabling the port did indeed make the LAN port status go to DOWN when viewed through the "nwmgr" command, which I think is what you would be looking for.

Hi,

you can tell me how you did this result from the output command.

"lan2 and lan5 appear to be LOM3 on blade 4 and LOM 4 on blade 6"

Thanks

[Torsten.]

Look at this line:

3/0/0/2/0/0 ioslot-1/4/5

This means enclosure 1 blade 4

And no go to the OA and use

OA> parstatus -c 1/4 -V


and you will find the NICs.

Hi,

when i login to HP ProCurve 6120XG Blade Switch with web interface i see 16 ports, How do I know which port i want to disconnect.

Thanks

[Duncan Edmonstone]

I thought we just told you this?

port 4 on the procurve in interconnect bay 1 and port 6 on the procurve in interconnect bay 2

Here's what you need to do:

1. Check the NIC ports are currently up in HP-UX using "nwmgr" - you should see lan2 and lan5 listed as having an interface status of UP.

2. Login to the procurve web management console for the switch in interconnect bay 1.

3. Click on the "Configuration" tab

4. Select port 4 on the diagram of downlink ports (listed as invisible)

5. Once its selected it should have a blue box around it.

6. Click on the "disbale selected ports" button

7. Back in HP-UX, if you run nwmgr you should now see lan2 as DOWN.

8. Re-enable when you are done...

Obviously you can repeat this operation on the management console for the other switch and select port 6 to disable lan5

... or just "disconnect" the blade from the interconnect bays using the OA (see also earlier reply).

[itrc55]

Hi,

I did not understand until now how do you know the port 4 on the procurve in interconnect bay 1 for lan2 and port 6 on the procurve in interconnect bay 2 for lan5.

only this point

Very Thanks

[Torsten.]

See the figure about the port mapping:

[Torsten.]

... or connect to the OA, select the blade and click port mapping.
