[Users] IB topology config and polling state

[Weiny, Ira]

There are a few issues for routing in that diagram but the links should come up.

I assume there is some backplane between the blade servers and the switch in that chassis?

Have you gotten libipathverbs installed?

In ipathverbs there is a serdes tuning script.

https://github.com/01org/libipathverbs/blob/master/truescale-serdes.cmds

Does your libipathverbs include that file?  If not try the latest from github.

Ira

Hi Hal,
Thanks for the reply, I've attach a pdf with the diagram topology, I don't know if this is the best way to go or if there's another way to connect and setup the IB network, tips and suggestions will be very appreciated, also the mezzanine cards are already installed on the blade hosts:
# lspci

41:00.0 InfiniBand: QLogic Corp. IBA7322 QDR InfiniBand HCA (rev 02)

Thanks in advance,
Cheers,

German

Hi again German,

Looks like you made some progress from yesterday as the qib ports are now Polling rather than Disabled.

But since they are Down, do you have them cabled to a switch ? That should bring the links up and the port state will be Init. That is the "starting" point.

You will also then need to be running SM to bring the ports up to Active.

Hi all,
I don't know if this is the mailist list for this kind of topic but I'm really new to IB and I've just install two SX6036G gateways connected to each other through two ISL ports, then I've configured a proxy-arp between both nodes (sm is disable on both gw's):

GWIB01 [proxy-ha-group: master] (config) # show proxy-arp ha

Load balancing algorithm: ib-base-ip
Number of Proxy-Arp interfaces: 1

Proxy-ARP VIP
=============
Pra-group name: proxy-ha-group
HA VIP address: 10.xx.xx.xx/xx

Active nodes:
ID                   State                IP
--------------------------------------------------------------
GWIB01               master               10.xx.xx.xx1
GWIB02               standby              10.xx.xx.xx2
Then I setup two SX6018F switches (SWIB01 and SWIB02), one connected to GWIB01 and the other connected to GWIB02. The SM is configured locally on both SWIB01 & SWIB02 switches. So far so good, after this config I setup a commodity server with a MLNX IB ADPT FDR to the SWIB01 & SWIB02 switches, config the drivers, etc and then get it up & running fine.

Finally I've setup a HP Enclosure with an internal IB SW (then connect port 1 of the internal SW to GWIB01 - link is up but LLR status is inactive), install one of the blades and I see the following:

# ibstat
CA 'qib0'
    CA type: InfiniPath_QMH7342
    Number of ports: 2
    Firmware version:
    Hardware version: 2
    Node GUID: 0x0011750000791fec
    System image GUID: 0x0011750000791fec
    Port 1:
        State: Down
        Physical state: Polling
        Rate: 40
        Base lid: 4660
        LMC: 0
        SM lid: 4660
        Capability mask: 0x0761086a
        Port GUID: 0x0011750000791fec
        Link layer: InfiniBand
    Port 2:
        State: Down
        Physical state: Polling
        Rate: 40
        Base lid: 4660
        LMC: 0
        SM lid: 4660
        Capability mask: 0x0761086a
        Port GUID: 0x0011750000791fed
        Link layer: InfiniBand
So I was wondering if maybe the SM is not being recognized on the Blade system and that's why is not passing the Polling state, is that possible? Or maybe is not possible to connect an ISL between the GW and the HP internal SW so that the sm is available or maybe the inactive LLR is causing this thing, any ideas? I thought about connecting the ISL of the HP IB SW to the SWIB01 or SWIB02 instead of the GW's but I don't have any available ports.
Thanks in advance,
Cheers,

German
