patch installation unconfigured the system

[G_18]

After the installation of the patch PHSS_20975 and reboot the configuration of the system was lost.
Now I am even unable to configure my ether card manually.
Eventhough I give the ipaddress and hostname using "sam" it doesn't work.
Whenever I use #ifconfig lan0 it gives " no such interface".
Whenever I go to the init level 1 and back to init 3 it hangs.
Please give a proper solution.

Thanks.

Strange one..
Ok, try and boot the machine into single user mode. Once there, mount -a and do an ioscan -fknC lan to make sure that /dev/lan0 indeed exists. If it does, I think the easiest thing will be to enable your ether card with landiag, lan, reset, and then a set_parms initial to get your networking back up and running.

Another thing, just check that the /etc/rc.config.d/netconf file is a) there and b) not corrupted. I had a situation where during a patch installation the contents of dmesg were appended into this file. If the file is corrupt, take the copy from /usr/newconfig/etc/rc.config.d and run the set_parms initial.

wierder things have happened.
