ONTAP 7-Mode Transition

Viewing transitioned SAN configurations

Contributors

The LUN serial numbers and LUN IDs of SAN volumes change after transition. To view the transitioned SAN configurations, you can generate the mapping of the old LUNs to the new transitioned LUNs by using the 7-Mode Transition Tool CLI and export the LUN mapping information to a .csv file.

Storage cutover must have completed successfully.

Steps

  1. To generate LUN mapping information, run the following command from the CLI:

    transition cbt export lunmap -p project_name -o file_path

    C:\Program Files\NetApp\7-Mode Transition Tool>transition cbt export lunmap -s SanWorkLoad -o c:/Libraires/Documents/7-to-C-LUN-MAPPING.csv
Successfully exported 7 to C LUN mapping for 'SanWorkLoad'

    The following example shows a sample LUN mapping file:

You must perform the required post-transition tasks on the host before restoring access to the transitioned ONTAP volumes.
