ONTAP 7-Mode Transition

Preparing the 7-Mode system for transition

Before starting a transition, you must complete certain tasks on the 7-Mode system, such as adding the SnapMirror license and the 7-Mode system to communicate with the target cluster.

All the 7-Mode volumes that you want to transition must be online.

Steps

  1. Add and enable the SnapMirror license on the 7-Mode system:

    1. Add the SnapMirror license on the 7-Mode system:

      license add license_code

      license_code is the license code you purchased.

    2. Enable the SnapMirror functionality:

      options snapmirror.enable on

  2. Configure the 7-Mode system and the target cluster to communicate with each other by choosing one of the following options:

    • Set the snapmirror.access option to all.

    • Set the value of the snapmirror.access option to the IP addresses of all the LIFs on the cluster.

    • If the snapmirror.access option is legacy and the snapmirror.checkip.enable option is off, add the SVM name to the /etc/snapmirror.allow file.

    • If the snapmirror.access option is legacy and the snapmirror.checkip.enable option is on, add the IP addresses of the LIFs to the /etc/snapmirror.allow file.

  3. Depending on the Data ONTAP version of your 7-Mode system, perform the following steps:

    1. Allow SnapMirror traffic on all the interfaces:

      options interface.blocked.snapmirror ""

    2. If you are running Data ONTAP version 7.3.7, 8.0.3, or 8.1 and you are using the IP address of the e0M interface as the management IP address to interact with 7-Mode Transition Tool, allow data traffic on the e0M interface:

      options interface.blocked.mgmt_data_traffic off
