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.

  • The disk and shelf configuration at both sites should be identical.

    If a non-mirrored aggregate is used, the disk and shelf configuration at each site might be different.

    Note
    All disks in the disaster recovery group must use the same type of connection and be visible to all of the nodes within the disaster recovery group, regardless of the disks being used for mirrored or non-mirrored aggregate.

  • The system connectivity requirements for maximum distances for disk shelves, FC switches, and backup tape devices using 50-micron, multimode fiber-optic cables, also apply to FibreBridge bridges.

  • A mix of IOM12 modules and IOM3 modules is not supported within the same storage stack. A mix of IOM12 modules and IOM6 modules is supported within the same storage stack if your system is running a supported version of ONTAP.

Note
In-band ACP is supported without additional cabling in the following shelves and FibreBridge 7600N bridge:

  • IOM12 (DM600S) behind a 7600N bridge with ONTAP 9.4 and later

  • IOM12 (DM120S and DM240S) behind a 7600N bridge with ONTAP 9.4 and later

Note
SAS shelves in MetroCluster configurations do not support ACP cabling.
  1. Enabling IP port access on the FibreBridge 7600N bridge if necessary
    If you are using an ONTAP version prior to 9.5, or otherwise plan to use out-of-band access to the FibreBridge 7600N bridge using telnet or other IP port protocols and services (FTP, ExpressNAV, ICMP, or QuickNAV), you can enable the access services via the console port.
  2. Configuring the FC-to-SAS bridges
    Before cabling your model of the FC-to-SAS bridges, you must configure the settings in the FibreBridge software.
  3. Cabling disk shelves to the bridges
    You must use the correct FC-to-SAS bridges for cabling your disk shelves.
  4. Verifying bridge connectivity and cabling the bridge FC ports
    You should verify that each bridge can detect all of the disk drives, and then cable each bridge to the local FC switches.
