Failed to configure IPv6 interface(s): eri1 - how to debug?

Question

I have a problem configuring the second network interface for IPv6 under Solaris 10. The first interface, eri0, is configured and works fine. The second one, eri1, has a link-local address but no global address. Both links are up and working, I can ping eri1 via IPv4 (10.0.1.9) from an external host.

        ether 0:3:ba:b:fd:4bMy setup is the same for both interfaces:
- empty files /etc/hostname6.eri0 and /etc/hostname6.eri1
- both NICs connected to the same switch, with a L2-adjacent IPv6 router.
Last messages from the serial console are:

(at this point, I issued 'svcadm restart network/physical')

Do you have any ideas? Where to look?

Answer 1

Thank you for the answer! I've found an option 'local-mac-address?' (the question mark is a part of the parameter name) in the 'ok' prompt.
More info for next generations:
1. Get to the 'ok prompt' (OpenBoot prom)
2. Type 'printenv' to see the current settings, look for 'local-mac-address?'
3. Set the parameter to 'true': 'setenv local-mac-address? true'
4. Type printenv again to see if the option was actually changed
This option is also described in Gentoo OBP reference:

Thanks!
