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 Guide for a description of how to replace the physical interface.

2. Plumb in and bring up the test address by typing the following command.

   # ifconfig hme0 <test address configuration>

   ---

   Note –

   The test address configuration is the same as that configured in the /etc/hostname.hme0 file. Using the previous procedure, the test configuration is the same configuration that is displayed in step 1.

   ---

   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.

   See Configuring Test Addresses for more details about how to configure test addresses.
