After converting the protocol of the host ports, perform additional steps to use the new protocol.

The steps you might need to complete depend on the starting and ending protocols of the baseboard host ports and the HIC ports.

Complete FC to iSCSI conversion

If you previously had FC host ports and you converted to iSCSI, you might need to modify your existing configuration to support iSCSI. The following procedure is only applicable if there is no iSCSI HIC present.

About this task

This task applies only if you are converting a storage array that has already been in use.

This task does not apply if you are converting a new storage array that does not yet have hosts and volumes defined. If you converted the host-port protocol of a new storage array, see Installation and Maintenance Guide page to complete the setup for each protoco. Find the following guides according to the corresponding version of your storage system:

  • Linux express configuration

  • VMware express configuration

  • Windows express configuration

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 ThinkSystem 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 ThinkSystem System Manager.

    If you need instructions to add hosts or host clusters, refer to the online help for ThinkSystem 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.

What’s next?

Your host protocol conversion is complete. You can resume normal operations.

Complete iSCSI to FC conversion (not applicable to controllers without two base-board ports on the rear)

If you previously had iSCSI host ports and you converted to FC, you might need to modify your existing configuration to support FC. The following procedure is only applicable if no FC HIC is present.

This task applies only if you are converting a storage array that has already been in use.

This task does not apply if you are converting a new storage array that does not yet have hosts and volumes defined. If you converted the host-port protocol of a new storage array, see Cabling DE Series hardware to install cables and SFPs. This task does not apply if you are converting a new storage array that does not yet have hosts and volumes defined. If you converted the host-port protocol of a new storage array, see the Cabling procedures to install cables and SFPs. Then, to complete the setup for each protocol, follow the instructions the instructions on the Installation and Maintenance Guide page to find the following guides according to the corresponding version of your storage system:

  • Linux express configuration

  • VMware express configuration

  • Windows express configuration

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 ThinkSystem 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.

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.

    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.

Your host protocol conversion is complete. You can resume normal operations.
