enabling ports on dual channel HBA

[Doug Wilburn]

I just installed two FCA2684DC HBA's in my ES47 running Tru64 5.1B. I set the NVRAM by going into WWIDMGR and setting topo to "fabric". When I booted the system, I get connectivity to the SAN switch using port 1 on each card, but no connectivity using port 0. Is there a jumper on these cards or a driver or OS setting that enables both ports or is it possible I got two bad cards that behave the same way?

No, I don't think there is a jumper on the board to disable it. This simply works out-of-the-box.

If the SAN switch does not show a link, it could be a problem with the switch port, the cable or the adapter port. Just swap the connections to see if a link comes up.
You can also use the WWIDMGR for some basic troubleshooting:
>>>wwidmgr -show ports

Should show the WWN of the SAN switch.

Thanks, but I'm using the same fiber cable and plugging into the same switch port - all I'm doing is moving the same cable from port 1 on the hba to port 0. Then I lose connectivity at the switch.

[Uwe Zessin]

Interesting. If both cards show this behaviour it is quite unlikely that both are damaged.

After you have moved the cable to the adapter's port-0, can you run ">>> init" and ">>> wwidmgr -show ports" ?

Thanks for sticking with me on this. I'm going to have to schedule some down time with users. It will likely be early next week. In the meantime, I wondered if you could tell me what the emx driver error msgs mean in the attached file (taken from /var/adm/messages). All I could find is that they were probably just informational, rather than errors affecting functionality of the hba's.

I haven't received permission yet for downtime, but here is a little more info. I did not install NHD7 - I assumed that the driver I needed was included in Tru64 5.1B PK6. Perhaps a bad assumption? Also, when I built a new kernel following install of hba's and inserting "config_driver emx" in the /sys/conf/NAME file, I hadn't booted to genvmunix, ie. I was still running my old kernel. Would that make a difference when building a new kernel?
