Network card problem

Amit Kureel — Mon, 23 Apr 2001 11:19:07 GMT

Hello friends,
I have an L-Class server, which is 9000 m/c with HP-uX 11.00 and 3 lan cards on it. Till Saturday it was working fine, but since this morning, we are suddenly unable to ping to it..

I tried lanadmin and network card reset, I also tried a reboot, I also checked the status through lanscan and the status I see the status of the lan0 as up and the status of lan1 and lan2 as down.... lan0 is configured with proper host-IP, but through sam it's status is shown as disabled and any attempt to enable it fails without any message, self ping on the loopback and host-IP is working... I even tried to connect through a cross-cable connection, but even then I am unable to ping to it...

Any suggestions, how can I remove the configuration entries of the 3 configured cards and re-configure them through sam, because SAM doesn't show any menu item that allows me to remove a card-configuration.

Can anybody help....?

Check out your /etc/rc.config.d/netconf file. It is this file which holds all the IP Address, SubNet Mask and Gateway information. You shoudl see sections for all 3 LAN cards , i.e. LAN[0) , LAN[1] , LAN [2]. You could also try looking at the man page for set_parms to try and reconfingure the default LAN card. Are you sure that the network cables going to the L class are "live" and you have not got a problem with a dead Network Hub or Switch.

To use sam with 100BaseT lan cards, ensure you have the latest sam and lan card patches. A good start would be :

PHKL_18543 PM/VM/UFS/async/scsi/io/DMAPI/JFS/perf patch ( do NOT reinstall this one!!!)
PHKL_20016 2nd CPU not recognized in G70/H70/I70
PHNE_22244 Built-in PCI 100BASE-T patch
PHCO_22269 cumulative SAM/ObAM patch
PHNE_22353 LAN product cumulative patch
PHNE_22397 cumulative ARPA Transport patch
PHKL_22432 VxFS 3.1 icache cumulative patch
PHNE_22566 Cumulative STREAMS Patch
PHKL_22589 LOFS, select(), IDS/9000 and umount race fix
PHKL_22840 IDS/9000; syscalls related to file/socket
PHCO_23651 fsck_vxfs(1M) cumulative patch
PHKL_23812 probe,sysproc,shmem,pm,mmap cumulative patch

Check and ensure you do not have duplicate IP addresses:

#netfmt -f /var/adm/nettl.LOG00 > /tmp/log.out

#vi /tmp/log.out >> look for something like "trying to be our address."

If you want to tear down the card and start over, you can use ifconfig unplumb. Take a look at the man page for ifconfig.

Also ensure all of your IP addresses are on different subnets.

Check your network connections before changing the network configuration on your system. The network must be alive and ok. Have the network personnel check the route first.
