Making nondisruptive changes to the interface groups

You can use the cf takeover and cf giveback commands to make changes to interface groups in the HA pair in a nondisruptive manner.

About this task

Changes to the /etc/rc file require a reboot to make the changes effective. You can use the cf takeover and cf giveback commands to take over one node in the HA pair, causing it to reboot while its storage is taken over by the partner.

Steps

  1. Edit the /etc/rc file on the desired node to modify the interface groups.

    See the Data ONTAP Network Management Guide for 7-Mode for more information about configuring interface groups.

  2. From the partner node (the partner of the node on which you performed step 1), enter the following command:
    cf takeover
  3. Enter the following command:
    cf giveback

    The node on which the changes were made reboots and its /etc/rc file is reread. The rc file is responsible for creating the interface groups.

  4. Repeat these steps, making any required changes to the /etc/rc file on the partner node.
