Download PDF of this page

You can use SAS optical cables to hot-add a SAS disk shelf to an existing stack of SAS disk shelves in a direct-attached MetroCluster FC configuration, or as a new stack to a SAS HBA or an onboard SAS port on the controller.

  • This procedure is nondisruptive and takes approximately two hours to complete.

  • You need the admin password and access to an FTP or SCP server.

  • If you are adding an IOM12 shelf to a stack of IOM6 shelves, see Hot-adding IOM12 shelves to a stack of IOM6 shelves.

This task applies to a MetroCluster FC configuration in which the storage is connected directly to the storage controllers with SAS cables. It does not apply to MetroCluster FC configurations using FC-to-SAS bridges or FC switch fabrics.
