linkloop errors

BFA6 — Thu, 09 May 2002 14:19:50 GMT

I've got 2 machines nodeA and nodeB which are to be clustered. I'm having problems with the linkloop on the standby card in nodeB

linkloop from nodeA primary card to nodeB standby card I get the following
Link connectivity to LAN station: 0x001083FA6174
error: get_msg2 getmsg failed, errno = 4
-- FAILED
frames sent : 1
frames received correctly : 0
reads that timed out : 1

If I linkloop from nodeB stanby to nodeA primary I get this message

Link connectivity to LAN station: 0x080009A3F40E
error: expected primitive 0x30, got DL_ERROR_ACK
dl_error_primitive = 0x2d
dl_errno = 0x04
dl_unix_errno = 57
error - did not receive data part of message

Is there anything else I can look at, or have I got a faulty network card ?

Thanks in advance

Hilary

Use landiag to diagnose the card. First ..
# lanscan
==> take note of "card instance #" in the 3rd column.
# landiag
Enter command: lan
Enter command: ppa
Enter PPA number :
...either 0 or 1 usually
Enter command: display

What do you see..

How are you issuing the linkloop command?

linkloop -i 0x

This is the result from landiag

As to the linkloop command

I've just had a look in sam at the same card, and sam has the speed set to 100 half duplex, but landiag has the speed set to 10.

Any ideas why they differ & is this causing my linkloop failures ?

Hilary

Hi,

You could try setting the card to 100FD.
On the second page of the lanadmin stats
the late collisions maybe reporting something.
If so try try this:

# lanadmin -X 100FD 0 (lan card No.)

if this works update your /etc/rc.config.d/hpnetworktype file

The card would not let me change the speed settings - kept giving me an error message.
Then to confuse matters, the problem resolved itself, and re-appeared on the secondary card in nodeA

We have amended the port on the switch to mirror the card settings, and also swapped the cable for good measure, and everything is now OK.

Thank you for your help.

Hello,

Maybe the hub/switch is 100MBps and the card is 10MBps

grep 57 /usr/include/sys/errno.h
#define ENOLINK 57 /* the link has been severed */

Argghhh I spoke to soon. The problems has jumped back to the secondary card on NodeB. As I've had the card working before, I'm guessing it's a speed issue.

Success at last.

It was down to a combination of incorrectly labbelled cables (oops!) and speed problems on the switch.

Thanks for all the replies.

TG - I couldn't get to two of your links as they appear to be on the Americas site, but thanks anyway

Hilary,

Any links you see to the US site, are probably mirrored on the europe site - just replace 'us-support2' with 'europe-support' in the URL.

Problem Description

I am running HP-UX 10.20 on a K200 server. I get the following errors
when I attempt to reset the built-in 10 MB LAN card:

error: expected primitive 0x06, got DL_ERROR_ACK
dl_error_primitive = 0xe8
dl_errno = 0x04
dl_unix_errno = 16

How can I resolve these errors?

Configuration Info

Operating System - HP-UX
Version - 10.20
Hardware System - HP9000
Series - K200

Solution

To resolve your errors, change the switch port on the LAN card.

second link

Network Connectivity: Two systems cannot communicate with each other

Problem Description

I have a J200 and C180. These systems can communicate with
other units, but not to each other (I cannot ping, ftp, rlogin).

A linkloop on the J200 produced the following output:

error: get_msg2 getmsg failed, errno=4

A linkloop on the C180 receives a different error:

error: expected primitive 57 0x20 got dl_error_ack

What is the problem?

Configuration Info

Operating System - HP-UX
Version - 10.20
Hardware System - HP 9000
Series - J200

Solution

In this particular case the problem is a cable flaw in the C180.
To correct this problem, use the following steps:

1. Error 57 is usually a severed LAN, so reset the C180 card with
landiag.

2. Change the cable on the C180.
