Complete iSCSI to FC/iSCSI conversion

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

You can use either of the following options to use the new FC ports. The exact steps depend on your current and planned network topologies.

Option 1 assumes that you want to attach new FC hosts to the array. Option 2 assumes that you want to convert the hosts connected to the converted ports from iSCSI to FC.

Option 1: Move iSCSI hosts and add new FC hosts

  1. Move any iSCSI hosts from the new FC ports to the ports that remain iSCSI.
  2. If you are not already using dual-protocol SFPs, remove any FC SFPs.
  3. Attach new FC hosts to these ports, either directly or by using a switch.
  4. Configure FC networking for the new hosts and ports.

Option 2: Convert iSCSI hosts to FC

  1. Shut down the iSCSI hosts connected to the converted ports.
  2. Provide an FC topology for the converted ports. For example, convert any switches from iSCSI to FC.
  3. If you are not already using dual-protocol SFPs, remove the iSCSI SFPs from the converted ports, and replace them with FC SFPs or dual-protocol SFPs.
  4. Attach cables to the SFPs in the converted ports, and confirm they are connected to the correct FC switch or host.
  5. Power on the hosts.
  6. Configure the FC hosts.
  7. Edit the host partition to add the FC host port IDs and remove the iSCSI host port IDs.
  8. After the new FC hosts reboot, use the applicable procedures on the hosts to register the volumes and to make them available to your operating system.
    • Depending on your operating system, two utilities are included with the storage management software (hot_add and SMdevices). These utilities help register the volumes with the hosts and also show the applicable device names for the volumes.
    • 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.
