When I ReBoot Itanium, Network Connection Whacked

[Bill Brutzman]

It seems that I have to unplug the Cat-5 wire... and reconnect the Cat-5 wire... for the connection to come back to life.

This is using HP-Ux 11i v2

Certainly not normal.   What model server?

What do you see as far as errors or symptoms?  Do you get any errors during boot up (check the /etc/rc.log file)?

Which driver do you see the issue with ?
If you know the interface name (like lan0, lan1 ...), then, check the driver name from "ioscan -fC lan" at least.

Login using the console and see if the connection has been disabled by the infamous dead gateway setting. You may see a message like this in syslog:

vmunix: Dead gateway detection can't ping the last remaining default gateway

Or run this command:

ndd -get /dev/ip ip_ire_status

If you see the message, you need to disable this default setting on all your HP-UX servers.

First, turn off the gateway detection:

ndd -set /dev/ip ip_ire_gw_probe 0

Then edit the file /etc/rc.config.d/nddconf and add these 3 lines:

TRANSPORT_NAME[0]=ip
NDD_NAME[0]=ip_ire_gw_probe
NDD_VALUE[0]=0

That should eliminate the loss of communication.
