Getting rid of kernel warnings for unusable HW

[Ralph Grothe]

Hello,

I did an upgrade on a couple of L2000 servers from HP-UX 11.00 to 11.11

Prior to the upgrade new Tachyon XL2 FC adapters had been inserted, while the former FC mass storage adapters that used the fcT1 driver remained in the machines.

Already during installation I got the warning message that the old FC adapters weren't supported by HP-UX 11i at all.
This same warning now appears in syslog.log (or at the console) each time the machine boots up.
(please, have a look at attachment)

Apart from the little cosmetic syslog disturbance I think that when the HW isn't supported anyway, why shouldn't I kick out the driver from the kernel to free up memory and get rid of further warnings.

This is what ioscan and kmsystem return:

# for c in fc fcp;do ioscan -knfC$c;done
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 0 0/3/0/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channe
l Mass Storage Adapter
/dev/td0
Class I H/W Path Driver S/W State H/W Type Description
==================================================================
fcp 0 0/3/0/0.8 fcp CLAIMED INTERFACE FCP Protocol Adapter


# for mod in fc fcp td;do kmsystem -q $mod;done
kmsystem: Invalid module, subsystem or driver name : fc
Module Configured Loadable
=================================================
fcp Y -

=================================================
td Y -


Can I deinstall the driver (btw, which one?) by kmsystem, and prepare for next reboot by kmupdate?

Regards

Hi, Raplh!

The warning is issued from the fcT1 driver (fcT1.c). I didn't test myself, but I don't believe that your can get rid if these messages by removing that driver... look at the dependencies in /usr/conf/master.d/*:

td -> fcms fcp_cdio fcpdev fcparray fcpmux sctl wsio diag1 diag2
fcpmux -> fcp sctl
fcp -> fcT1 fcT1_cntl fcT1_fcp fcpdev fcparray fcp_cdio fcms sctl wsio

So it looks like fcT1 is included as dependency of td.

Regards...
Dietmar.

Hi Ralph
You may want to take out those old fiber cards from machine.

Thanks.
