    Hot-adding an IOM12 disk shelf to a stack of IOM6 disk shelves in a bridge-attached MetroCluster configuration

    04/12/2021

    Depending on your version of ONTAP, you can hot-add an IOM12 disk shelf to a stack of IOM6 disk shelves in a bridge-attached MetroCluster configuration.

    To perform this procedure, see Hot-adding shelves with IOM12 modules to a stack of shelves with IOM6 modules.
