Description
It is a problem of not recognizing "bge1" when SB is exchanged from "380-0979(K1 Board)" to "380-1168(K2 Board)".

Steps to Follow

Problem Statement
After exchanging the system boards 380-0979 for 380-1168 on a Sun
Fire[TM] V20z, onboard bge1 interface is not recognized.
root@wood% ifconfig bge1 plumb
ifconfig: SIOCSLIFNAME for ip: bge1: no such interface
This issue is caused by the differences of the device path of bge1
between 380-0979 and 380-1168 system boards.

Resolution:
After the system boards are exchanged the restructuring of bge1 is needed
as follows.
1. Delete bge1 entry from /etc/path_to_inst file.
2. Delete the files corresponding to bge1 from /dev and /devices.
3. Run reconfiguration boot.

Comment: Good info. When you show the device paths, make it plain that they came from /etc/path_to_inst.

In your resolution, change path_to_inst to /etc/path_to_inst.

CHANGE:
2. Delete the files correspond to ...
TO
2. Delete the files corresponding to ...

Give examples of the /dev and /devices files to delete.

Would the devfsadm command work as well as a reconfiguration reboot? If so, include that as an option.
