faulty lan0 disable procedure

[Martin Napoli_1]

Hi all,

I have an B180L which on-board ether port is faulty.
Unfortunatelly I have an application that uses both lan0 and lan1 and does not allow the use of other lan interface.
I would like to know if there is any way to 'delete' on-board lan and set two pci ether card as lan0 and lan1 ..or simply modify the lan# of the current installed cards.

Any suggestion are welcome!

Thanks in advance.

Best regards,
Martin

I don't think you can modify lan instance numbers. Either you change faulty on-board lan0 or change your configuration in application to use lan1 and lan2.

[A. Clay Stephenson · Accepted solution]

You can reorder the LAN instance numbers:



ioscan -f | grep -e "INTERFACE" -e "DEVICE" | grep -v -i "target" | awk '{printf("%-20.20s %-12.12s %3d\n",$3,$1,($2 + 0))}' > /myfile

Using vi, edit /myfile and change the lan instances as you wish but make sure than no instance numbers are duplicated.

mv /stand/ioconfig /stand/ioconfig.safe
mv /etc/ioconfig /etc/ioconfig.safe
shutdown -r -y 0

The system will stop the reboot at the ioinitrc prompt because of the missing files:
Issue this command:
/sbin/ioinit -c
/sbin/ioinit -f /myfile -r

You may get warnings like "input identical to kernel" -- these are normal and expected and may be safely ignored. The "-r" triggers a reboot.

You lan configurations should be correct now. Man ioinit for details. This same procedure can also be used to change disk controller instances as well but use this with caution.
