dear all,

i'm using solaris 10 u7 (05/09) with a smoothly working gigabit nic.

now i'd like to activate the on-board network interface as an
*additional* device.
right now it's not available as i had it disabled in the bios during
original installation.
(ifconfig does not list it.)

so my question is:

how do i trigger detection and configuration by solaris *without* changing
the existing gigabit nic setup?

thanks for your input.

chris

Well, I'd start by UNDOING whatever it was you did to disable it in the
BIOS!

Then do a reconfiguration boot: boot -r

That would work on SPARC hardware. X86 may be somewhat different.

Once you've re-enabled it in the BIOS, boot Solaris. At a root command-line,
run "devfsadm" (shouldn't be necessary, but it doesn't harm) and then
"/sbin/ifconfig -a plumb". Then the new interface should appear in your
ifconfig -a output.

If it's on-board, chances are it'll have the same device name as your
existing interface. If your current interface is e1000g0, the new one
will be e1000g1, or e1000g2, or whatever.

Then - IF the new interface is e1000g1, for example - simply echo the IP
address into /etc/hostname.e1000g1 and reboot, or do a "svcadm restart
network/physical"

Will this new interface be on the same subnet as the existing? That's what
I'm assuming. If not, you may need to customize /etc/netmasks as well.

Probably nothing. Just plumb it and setup the files.

On a X100/V100 I might do:

ifconfig dmfe1 plumb
ifconfig dmfe1 <some IP> <netmask> ......
ifconfig dmfe1 up

And the interface will work. To make it permanent, look for files
matching "ls /etc/hostname.*" and create one with the extension of the
interface, make a /etc/hosts entry too. And change /etc/defaultrouter
if neccessary.

BTW, if it is on the same network/switch, you do need to consider that
the mac addresses are linked. I can't rememebr the exact setting, but
it is in NVRAM. You want each nic on the same LAN to have a different
MAC address or you can get some weird and unreliable behavior.
