Modifying IPMP Configurations

The IPMP configuration file /etc/default/mpathd contains three parameters that you can modify for your configuration requirements:

• FAILURE_DETECTION_TIME

• TRACK_INTERFACES_ONLY_WITH_GROUPS

• FAILBACK

How to Configure the /etc/default/mpathd 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. Edit the /etc/default/mpathd file.

   Change the default value of one or more of the three parameters.

   1. Type the new value for the FAILURE_DETECTION_TIME parameter.

      FAILURE_DETECTION_TIME=n

      where n is the amount of time in seconds for ICMP probes to detect whether an interface failure has occurred. The default is 10 seconds.

   2. Type the new value for the FAILBACK parameter.

      FAILBACK=[yes | no]

   3. Type the new value for the TRACK_INTERFACES_ONLY_WITH_GROUPS parameter.

      TRACK_INTERFACES_ONLY_WITH_GROUPS=[yes | no]

3. Restart the in.mpathd daemon.

   # pkill -HUP in.mpathd
