Telnet is failing.

[Rajesh SB]

Hi,

I am using HPUX 11.0 with june 2001 patch bundle on K570, 12H array additional btlan4 card (J3514A) and 8 Channel ACC/X.25 Card.

Some time I am not able to telnet or rlogin to node. Even the console will be hanging. If you observe in the syslog, only suspectable message is :
"
Jul 31 10:38:51 hornadu vmunix: btlan4: Hardware Reset Started on 8/4/2/0....This will take approximately 11 seconds

Jul 31 10:38:51 hornadu vmunix: btlan4: NOTE: 100Base-TX Full-Duplex started at 8/4/2/0....
"
Only I have to reset the system by switching off power.
Please, suggest me, What may be the problem?

Sorry for not assigning the points for my earlier questions.

Thanks & Regards,

Rajesh S

Sounds like a big problem with the LAN cable or the switch. But just to make sure, check the current speed and duplex setting with lanadmin -x and if you see auto-negotiation, you may need to shorten (or lengthen) the cable or tell the LAN card to not auto-negotiate. And make sure you are up to date on patches.

If the card still shows a reset, use another port on your switch and if it still is bad, you may have a bad LAN card.

hi,
i think resetting the card using lanadmin should solve instead of reboot. check the duplex settings on nic and at the switch and keep autonegotiation off and try.

Hi Rajesh,

Make sure your switch is set to 100 Full Duplex / Fixed instead of autosensing and also look for any latest patch that may address this problem.

Hope this helps.

The card is 100 mbps adn this problem occurs when :

1. there is a problem with the settign like compatibily between the port on server and that on teh swtich .

2. Loose cable or conenction.

What i suggest is to check on the network side what is the setting for the port , and change it on teh server accordingly .

You can use the following to test and change the settings :

1. Identify the LAN Interface using the lanscan command to know the interface.
2. Check for the speed set already using the Lanadmin command.
3. Use the command lanadmin ???X 100fd / or 100HDnmid or the ppa to change it to the desired one.
4. Check the setting using the lanadmin command again.
5. To change it permanently go to /sbin/init.d directory and make changes in the hpbaseconf files.
