Installing FC-to-SAS bridges and SAS disk shelves

You install and cable ATTO FibreBridge bridges and SAS disk shelves when adding new storage to the configuration.

This procedure is written with the assumption that you are using the recommended bridge management interfaces: the ATTO ExpressNAV GUI and ATTO QuickNAV utility.

You use the ATTO ExpressNAV GUI to configure and manage a bridge, and to update the bridge firmware. You use the ATTO QuickNAV utility to configure the bridge Ethernet management 1 port.

You can use other management interfaces instead, if needed, such as a serial port or Telnet to configure and manage a bridge and to configure the Ethernet management 1 port, and FTP to update the bridge firmware.

This procedure uses the following workflow:



  1. In-band management of the FC-to-SAS bridges
    Beginning with ONTAP 9.5 with FibreBridge 7600N or 7600N bridges, in-band management of the bridges is supported as an alternative to IP management of the bridges.
  2. Preparing for the installation
    When you are preparing to install the bridges as part of your new MetroCluster system, you must ensure that your system meets certain requirements, including meeting setup and configuration requirements for the bridges. Other requirements include downloading the necessary documents, the ATTO QuickNAV utility, and the bridge firmware.
  3. Installing the FC-to-SAS bridge and SAS shelves
    After ensuring that the system meets all of the requirements in the Preparing for the installation section, you can install your new system.
  4. Securing or unsecuring the FibreBridge bridge
    To easily disable potentially unsecure Ethernet protocols on a bridge, beginning with ONTAP 9.6 you can secure the bridge. This disables the bridge's Ethernet ports. You can also reenable Ethernet access.
