ifconfig: unknown error - A5506B

Sundar_7 — Tue, 12 Oct 2004 15:32:21 GMT

I upgraded the btlan driver for my Quad port lan card (A5506B) from verion B.11.00.01 to B.11.00.02.

From SD-UX logs, the upgrade was successful. But when the system boots up, LAN configuration fails and system doenst seem to recognize the APA LinkAgg.

Let's try to isolate the problem. Do not start APA. Just /sbin/init.d/net start

Does it start??

Hardware is there.

There appears to be no configuration in /etc/init.d/netconf

Also, there may not be a mac address (prior post will clarify that). I'd like to see what cstm/mstm/xstm says about the card.

# # /sbin/init.d/net start
ERROR: lan100 interface: ifconfig: Unknown error

There are a couple of things that could be going wrong here either APA is lying when it says it started sucessfully (so lan100 is not available), APA is not configured correctly with lan0-lan4, or APA did sucessfully start but somehow lan100 is not plumbed & so net strat is failing.

try "ifconfig lan100 plunb" & see if you can manually run ifconfig it up

try disabling APA & thus lan100 & configure lan0, then lan1, etc make sure it is not a problem with /etc/rc.config.d/netconf

A5506A is 32bit 33Mhz, A5506B is 64bit 33Mhz

Can you check which one you shall be installing.

Hope it helps

Thanks

Sundar,

'lanscan' doesn't return anything?. What if you specify 'lanscan /stand/vmunix.prev'. If it returns something, then I suspect a reboot is waiting. I would try to fix the 'lanscan' issue first. What does your 'dmesg' say?

Can you run "lanscan -q"?
Also can you post "/etc/rc.config.d/hp_apaconf" and "/etc/rc.config.d/hp_apaportconf"?
The link aggregation lan100 did not seem to be created successfully.
Your driver version seems to be very old. There is btlan patch with a fix related to APA. As others suggest, please apply the latest stable patch.

hmm..problem turned out to be something else.

LVs are mirrored in the order - where DISK1 is set as the primary boot disk with DISK2 as the secondary boot disk.

I did split the mirror before patching with the idea that if the patching is not successful, I will reverse-sync and roll back the patches.

When I split the mirror, the online /stand was from DISK2, not from the Primary disk DISK1.

I booted from DISK1 and installed the patches (compiled the kernel with /stand from DISK2). Now when the system is rebooted, Secondary loader loaded the /stand/vmunix from DISK1 (Old kernel) and mounted /stand from DISK2.

So, lanscan, dmesg (and some other commands) failed since the kernel image in the memory didnt match with the /stand/vmunix.

HP-APA script uses lanscan command but unfortunately doesnt do any kind of error checking :-(. So it reported "OK" during startup and when run from the command line.
