LAN init script initialization file confusion

[Ralph Grothe]

Hello,

I want to enforce set up of NICs with fixed parameters on runlevel changes through init scripts.
I have found out how to change a NIC's parameters (e.g. duplex, speed, auto on|off) either by the command lanadmin or by sam.
Unfortunately the NICs will lose these settings on next reboot.
Having a look at the init scripts in /sbin/init.d that fire up the NICs I stumbled over a whole bunch of conf files that are sourced by these scripts, namely the following (as far as ether/lan stuff is concerned)

# ls -1 /etc/rc.config.d/hp[bes]*
/etc/rc.config.d/hpbase100conf
/etc/rc.config.d/hpbtlanconf
/etc/rc.config.d/hpetherconf
/etc/rc.config.d/hpsppci100conf


Now I'm getting really confused, because I don't know which of those is valid for the drivers that drive the NICs on my boxes.
They all initialize the same bunch of shell arrays that hold the parameters for speed, duplex etc. per device.

Things get even more confusing when I have a look at what drivers which drive the ethernet NICs on our boxes.
They seem to differ from box to box (guess this is owe to other chips and components on the NIC boards)

e.g.
one box uses the driver btlan1:

# ioscan -kfdbtlan1
Class I H/W Path Driver S/W State H/W Type Description
==============================================================
lan 2 10/4/8 btlan1 CLAIMED INTERFACE HP HP-PB 100 Base TX card
lan 6 10/4/16 btlan1 CLAIMED INTERFACE HP HP-PB 100 Base TX card


whereas the other uses btlan (and btlan3):

# ioscan -nf -d btlan
Class I H/W Path Driver S/W State H/W Type Description
=========================================================================
lan 2 0/5/0/0/4/0 btlan CLAIMED INTERFACE PCI Ethernet (10110
009)
lan 3 0/5/0/0/5/0 btlan CLAIMED INTERFACE PCI Ethernet (10110
009)
lan 4 0/5/0/0/6/0 btlan CLAIMED INTERFACE PCI Ethernet (10110
009)
lan 5 0/5/0/0/7/0 btlan CLAIMED INTERFACE PCI Ethernet (10110
009)
lan 7 1/12/0/0/4/0 btlan CLAIMED INTERFACE PCI Ethernet (10110
009)
lan 8 1/12/0/0/5/0 btlan CLAIMED INTERFACE PCI Ethernet (10110
009)
lan 9 1/12/0/0/6/0 btlan CLAIMED INTERFACE PCI Ethernet (10110
009)
lan 10 1/12/0/0/7/0 btlan CLAIMED INTERFACE PCI Ethernet (10110
009)
# ioscan -knf -d btlan3
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
lan 0 0/0/0/0 btlan3 CLAIMED INTERFACE PCI Ethernet (10110019)
/dev/ether0


Other boxes still use other drivers.

So which of the parameter initialization files is to be edited?

/etc/rc.config.d/hpbase100conf

/etc/rc.config.d/hpbtlanconf

or

/etc/rc.config.d/hpetherconf

Ralph,

heres the answer; it depends on which driver

Driver duplex file Description Software

btlan hpbtlanconf
btlan0 hpeisabtconf
btlan1 hpbasetconf
btlan3 hpbase100conf Internal (core) LAN card
btlan4 hpgsc100conf
btlan5 hppci100conf "external" PCI card A5230A
btlan6 hpsppci100conf V-class PCI lan card
