After converting the protocol of the host ports, you must perform additional steps before you can use the new protocol.

The steps depend on the starting and ending protocols of the baseboard host ports and the HIC ports.

Complete FC to iSCSI conversion

If you converted all host ports from FC to iSCSI, you must configure iSCSI networking.

Steps

  1. Configure the switches.

    You should configure the switches used to transport iSCSI traffic according to the vendor's recommendations for iSCSI. These recommendations might include both configuration directives as well as code updates.

  2. From SANtricity System Manager, select Hardware › Configure iSCSI ports.

  3. Select the port settings.

    You can set up your iSCSI network in many ways. Consult your network administrator for tips on selecting the best configuration for your environment.

  4. Update the host definitions in SANtricity System Manager.

    Note If you need instructions for add hosts or host clusters, refer to the online help for SANtricity System Manager.

    1. Select Storage › Hosts.

    2. Select the host to which the port will be associated, and click View/Edit Settings.

      The Host Settings dialog box appears.

    3. Click the Host Ports tab.

    4. Click Add, and use the Add Host Port dialog box to associate a new host port identifier to the host.

      The length of the host port identifier name is determined by the host interface technology. FC host port identifier names must have 16 characters. iSCSI host port identifier names have a maximum of 223 characters. The port must be unique. A port number that has already been configured is not allowed.

    5. Click Delete, and use the Delete Host Port dialog box to remove (unassociate) a host port identifier.

      The Delete option does not physically remove the host port. This option removes the association between the host port and the host. Unless you remove the host bus adapter or the iSCSI initiator, the host port is still recognized by the controller.

    6. Click Save to apply your changes to the host port identifier settings.

    7. Repeat these steps to add and remove any additional host port identifiers.

  5. Reboot the host or perform a rescan so that the host properly discovers the LUNs.

  6. Remount volumes or start using block volume.

Complete iSCSI to FC conversion

If you converted all host ports from iSCSI to FC, you must configure FC networking.

Steps

  1. Install the HBA utility and determine initiator WWPNs.

  2. Zone the switches.

    Zoning the switches enables the hosts to connect to the storage and limits the number of paths. You zone the switches using the management interface of the switches.

  3. Update the host definitions in SANtricity System Manager.

    1. Select Storage › Hosts.

    2. Select the host to which the port will be associated, and click View/Edit Settings.

      The Host Settings dialog box appears.

    3. Click the Host Ports tab.

    4. Click Add, and use the Add Host Port dialog box to associate a new host port identifier to the host.

FC host port identifier names must have 16 characters. iSCSI host port identifier names have a maximum of 223 characters. The port must be unique. A port number that has already been configured is not allowed.

    5. Click Delete, and use the Delete Host Port dialog box to remove (unassociate) a host port identifier.

      The Delete option does not physically remove the host port. This option removes the association between the host port and the host. Unless you remove the host bus adapter or the iSCSI initiator, the host port is still recognized by the controller.

    6. Click Save to apply your changes to the host port identifier settings.

    7. Repeat these steps to add and remove any additional host port identifiers.

  4. Reboot the host or perform a rescan so that the host properly discovers mapped storage.

  5. Remount volumes or start using block volume.

Complete FC to FC/iSCSI conversion

If you previously had all FC host ports and you converted some of them to iSCSI, you might need to modify your existing configuration to support iSCSI.

You can use either of the following options to use the new iSCSI ports. The exact steps depend on your current and planned network topologies. Option 1 assumes that you want to attach new iSCSI hosts to the array. Option 2 assumes that you want to convert the hosts connected to the converted ports from FC to iSCSI.

Option 1: Move FC hosts and add new iSCSI hosts

  1. Move any FC hosts from the new iSCSI ports to the ports that remain FC.

  2. If you are not already using dual-protocol SFPs, remove any FC SFPs.

  3. Attach new iSCSI hosts to these ports, either directly or by using a switch.

  4. Configure iSCSI networking for the new hosts and ports. For instructions, refer to the Linux express configuration, Windows express configuration, or VMware express configuration.

Option 2: Convert FC hosts to iSCSI

  1. Shut down the FC hosts connected to the converted ports.

  2. Provide an iSCSI topology for the converted ports. For example, convert any switches from FC to iSCSI.

  3. If you are not already using dual-protocol SFPs, remove the FC SFPs from the converted ports, and replace them with iSCSI SFPs or dual-protocol SFPs.

  4. Attach cables to the SFPs in the converted ports, and confirm they are connected to the correct iSCSI switch or host.

  5. Power on the hosts.

  6. Use the NetApp Interoperability Matrix tool to configure the iSCSI hosts.

  7. Edit the host partition to add the iSCSI host port IDs and remove the FC host port IDs.

  8. After the iSCSI hosts reboot, use the applicable procedures on the hosts to register the volumes and to make them available to your operating system.

    • You can use the SMcli command -identifyDevices to show the applicable device names for the volumes. The SMcli is included in the SANtricity OS and downloadable through the SANtricity System Manager. For more information on how to download the SMcli through the SANtricity System Manager, refer to the Download command line interface (CLI) topic under the SANtricity System Manager Online Help.

    • You might need to use specific tools and options that are provided with your operating system to make the volumes available (that is, assign drive letters, create mount points, and so on). Refer to your host operating system documentation for details.
