Forcing a node into takeover mode

If a disaster has occurred, you can force the surviving node into takeover mode, so that the surviving node serves the data of the failed node.

  1. Enter the following command on the surviving node:cf forcetakeover -d

Data ONTAP causes the following to occur:

  • The surviving node takes over the functions of the failed node.
  • The mirrored relationships between the two plexes of mirrored aggregates are broken, thereby creating two unmirrored aggregates.

    This is called splitting the mirrored aggregates.

The overall result of using the cf forcetakeover -d command is that a node at the surviving site is running in takeover mode with all the data in unmirrored aggregates.
