Replacing a Physical Interface That Has Failed

You must do the following manual steps before replacing a physical interface that has failed. The following procedures use physical interfaces hme0 and hme1 as example interfaces. The procedures assume that both interfaces are in a multipathing group and that hme0 has failed. The procedures also assume that the logical interface hme0:1 has the test address.

These procedures assume that you are replacing the failed interface with the same physical interface name (for example, hme0 with hme0).

How to Remove a Physical Interface That Has Failed

1. Bring down the test address by typing the following command.

   # ifconfig hme0:1 down

2. 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 remove 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.
