No more network after patching

Borivant_1 — Mon, 23 Nov 2009 08:47:37 GMT

Hello,

I'm running HP-UX 11.11 on a RP-7410 with a network card ( HP A6794-60001 PCI 1000Base-T )

The network was OK before I installed GOLDQPK11i_B.11.11.0906.480.depot

Once installed and after a reboot, the server doesn't have any access to the network.

ioscan -fn give me the following result which seems ok to me :
......
target 9 1/0/1/0/0/1/1.7 tgt CLAIMED DEVICE
ctl 3 1/0/1/0/0/1/1.7.0 sctl CLAIMED DEVICE Initiator

here is he output from lanadmin display:

Does anyone have an idea how to make the network work again ?

Please check the below commands, as the network card is in CLAIMED condition, so should work.
1. lanscan
2. lanadmin -x 0
3. cat /etc/rc.config.d/netconf

Vivek

Hi,

You have to verify the file /etc/rc.config.d/netconf. The entry should be there for all your configured LAN...

Thanks for your suggestion, but everything seems ok :

The network conf did not change after patching

there is no output !

Re: No more network after patching

Borivant_1 — Mon, 23 Nov 2009 09:15:45 GMT

The network card seems to be configured :

# ifconfig lan0
lan0: flags=1843

Try to connect another n/w cable to the same port. may be it's n/w issue then.

Re: No more network after patching

Borivant_1 — Mon, 23 Nov 2009 09:19:33 GMT

already done without success.
And how patching HP-UX could damage a network cable ?

hi,

And how patching HP-UX could damage a network cable ?

that's not possible, if you are sure that the patches is the reason why it's not working them make a rollback of installed patches.

If you have re-built the kernel before patching, try to boot with that & check whether it's working or not.

Re: No more network after patching

Borivant_1 — Mon, 23 Nov 2009 09:35:43 GMT

I'm trying to rollback now.

but can U explain how to start on a previous kernel ?
That's always usefull, and I'll try that if the next attempt to patch gives the same result.

Re: No more network after patching

Vivek_Pendse — Mon, 23 Nov 2009 09:41:08 GMT

I guess, it will be vmunix.prev.
Please check under /stand.
After that, interrupt the system at isl & boot with it.

Michal Kapalka (mikap) — Mon, 23 Nov 2009 09:45:02 GMT

hi,

yust boot vmunix.prev instead of vmunix,

hope you made a backup of the previous kernel.

Aprt from booting server from old kernel, try to see if ur system can reach gateway.
ROUTE_GATEWAY[0]=89.1.0.45

cause from ifocnfig ur card appeared to be OK.

Can you get something checked from network port.

BR,
Kapil+

Re: No more network after patching

Borivant_1 — Mon, 23 Nov 2009 10:48:16 GMT

I uninstalled/resinstalled a patchset and everything seems to be OK now.
I have no explaination about what append.

mikap -> thanks for the procedure, I'll use it when patching the production server.

Thanks all for your help.
