How to Replace a Physical Interface That Has Failed

1. Refer to thecfgadm(1M) man page, Sun Enterprise 6x00, 5x00, 4x00, and 3x00 Systems Dynamic Reconfiguration User's Guide, or Sun Enterprise 10000 Dynamic Reconfiguration User Guidefor a description of how to replace the physical interface.

2. Bring up the test address by typing the following command.

   # ifconfig hme0:1 up

   This triggers the in.mpathd daemon to resume probing. As a result of this probing, in.mpathd will detect the repair. Consequently, in.mpathd causes the original IP address to failback from hme1.
