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.

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.

  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.
