Gigabit lan - cant create device file

Hi all,

got a strange problem;
N-class running Vpars - 1st Vpar is 1 CPU, 2nd Vpar is 5 CPU's, both 11i.
2nd Vpar has a Gigabit lan card installed (A4929A). However - we simply cannot create a device file for it. insf cant create it, rebooting doesnt create it, sam hangs if trying to create it.
Contact HP, they said a Vpars problem, upgrade to v2.02 which weve done, reinstalled the Gigabit driver and patch PHNE_26939 but still no device file!

I know the card is fine, it was working in the same class off an 11.0 boot disk fine - device file created when driver installed, it just work on 11i with Vpars.

Any ideas anyone ?

oops, that last bit should say it worked fine off the same N-class server using an 11.0 boot disk, it just WONT work on 11i with vpars.

Hi,

Did you try to power down / power up the lan card?

Check attachment.

Hi Stefan,

There is no /dev/gelan device file on 11i. All commands that previously accessed this device directly are now implemented through DLPI. I can try and dig out some more detailed documentation if you need it, or perhaps someone like Rick Jones will be able to offer a full explanation.

I take it the card is communicating on the network ok?

regards,

James.

Re: Gigabit lan - cant create device file

Hi James,

very interesting. If no device file how on earth do I configure it ? same hangs if it trys to configure the card with an IP. If I add something to netconf and reboot I end up wit no network at all (it knocks off the 100Mb lan card also and I have to crash it from the console).

The HPRC said yesterday no device file on 11i under vpars was a bug needing an upgrade to vpars, which hasnt fixed it. Is this not true?

Re: Gigabit lan - cant create device file


Your dead right James, no device file needed! got it working without one.

The problem was trying to use the 100Mb lan and the gigabit using different ip's and subnet masks - resulting in both being knocked out. I disabled the 100Mb lan, moved its cable to the gigabit, modified netconf, and it works fine! thanks for the help.

Cheers,

Stefan

Re: Gigabit lan - cant create device file


Simlpy add the entries into /etc/rc.config.d/netconf as per a normal lan card, or change over your existing one from lanX to lanZ (where lanZ is the Gigabit, in our case lan2).

Then restart, thats all. Dont forget to install the necessary patch first PHNE_26939.

Re: Gigabit lan - cant create device file

Hi Stefan,

Glad you got it working!

Yeah, the only thing you have to ensure is that you match the lan interface in the netconf file to the card instance number of the gigabit card. So, if from a lanscan or ioscan the instance number is 7, you have to put lan7 as the interface in netconf. I'd imagine you had a conflict with your 100BT card before, as you should have no problems having them both configured on different lans.

Regards,

James.
