How to Remove a Physical Interface That Has Failed (DR-Detach)

This procedure shows how to remove a physical interface on a system that supports DR. The procedure assumes that the following conditions already exist:

• Physical interfaces hme0 and hme1 are the example interfaces.

• Both interfaces are in the same IPMP group.

• hme0 has failed.

• Logical interface hme0:1 has the test address.

• You are replacing the failed interface with the same physical interface name, for example, hme0 with hme0.

You can skip Step 2 if the test address is plumbed by using the /etc/hostname.hme0 file.

1. On the system with the IPMP group configuration, assume the Primary Administrator role or become superuser.

   The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.

2. Display the test address configuration.

   # ifconfig hme0:1 hme0:1: flags=9040842<BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 3 inet 192.168.233.250 netmask ffffff00 broadcast 192.168.233.255

   You need this information to replumb the test address when replacing the physical interface.

3. Remove the physical interface.
