Preparing to hot-add a stack of SAS disk shelves and bridges

Preparing to hot-add a stack of SAS disk shelves and a pair of bridges involves downloading documents as well as the disk drive and disk shelf firmware.

Before you begin

  • Your system must be a supported configuration and must be running a supported version of ONTAP.

  • All disk drives and disk shelves in the system must be running the latest firmware version.

    You might want to update the disk and shelf firmware throughout the MetroCluster configuration prior to adding shelves.

    Upgrade, Revert or Downgrade Guide

  • Each FC switch must have one FC port available for one bridge to connect to it.

    Note
    You might need to upgrade the FC switch depending on the FC switch compatibility.

  • The computer you are using to set up the bridges must be running an ATTO supported web browser to use the ATTO ExpressNAV GUI: Internet Explorer 8 or 9, or Mozilla Firefox 3.

    The ATTO Product Release Notes have an up-to-date list of supported web browsers. You can access this document using the information in the steps.

  1. View the following document from the Lenovo Support Site:

    The Hardware Maintenance and Installation Guide for your expansion enclusre: ThinkSystem Storage DM Series

  2. Download content from the ATTO website and from the Lenovo website:
    1. Go to the ATTO FibreBridge Description page.
    2. Using the link on the ATTO FibreBridge Description page, access the ATTO web site and download the following:
      • ATTO FibreBridge Installation and Operation Manual for your bridge model.

      • ATTO QuickNAV utility (to the computer you are using for setup).

    3. Go to the ATTO FibreBridge Firmware Download page by clicking Continue at the end of the ATTO FibreBridge Description page, and then do the following:

      • Download the bridge firmware file as directed on the download page.

        In this step, you are only completing the download portion of the instructions provided in the links. You update the firmware on each bridge later, when instructed to do so in Hot-adding the stack of shelves.

      • Make a copy of the ATTO FibreBridge Firmware Download page and release notes for reference later.

  3. Gather the hardware and information needed to use the recommended bridge management interfaces—the ATTO ExpressNAV GUI and ATTO QuickNAV utility:
    1. Acquire a standard Ethernet cable to connect from the bridge Ethernet management 1 port to your network.
    2. Determine a non-default user name and password for accessing the bridges.

      It is recommended that you change the default user name and password.

    3. Obtain an IP address, subnet mask, and gateway information for the Ethernet management 1 port on each bridge.
    4. Disable VPN clients on the computer you are using for setup.

      Active VPN clients cause the QuickNAV scan for bridges to fail.

  4. Acquire four screws for each bridge to flush-mount the bridge L brackets securely to the front of the rack.

    The openings in the bridge L brackets are compliant with rack standard ETA-310-X for 19-inch (482.6 mm) racks.

  5. If necessary, update the FC switch zoning to accommodate the new bridges that are being added to the configuration.

    If you are using the Reference Configuration Files provided by Lenovo, the zones have been created for all ports, so you do not need to make any zoning updates. There must be a storage zone for each switch port that connects to the FC ports of the bridge.
