Option 1: Move FC hosts and add new iSCSI hosts
Step 1. Move any FC hosts from the new iSCSI ports to the ports that remain FC.
Step 2. If you are not already using dual-protocol SFPs, remove any FC SFPs.
Step 3. Attach new iSCSI hosts to these ports, either directly or by using a switch.
Step 4. Configure iSCSI networking for the new hosts and ports.
Option 2: Convert FC hosts to iSCSI
Step 1. Shut down the FC hosts connected to the converted ports.
Step 2. Provide an iSCSI topology for the converted ports. For example, convert any switches from FC to
iSCSI.
Step 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.
Step 4. Attach cables to the SFPs in the converted ports, and confirm they are connected to the correct
iSCSI switch or host.
Step 5. Power on the hosts.
Step 6. Configure the iSCSI hosts.
Step 7. Edit the host partition to add the iSCSI host port IDs and remove the FC host port IDs.
Step 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.
• Depending on your operating system, two utilities are included with the storage management
software (h ho ott__aad dd d and S SM Md deevviicceess). 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.
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.

Step 1. Shut down the iSCSI hosts connected to the converted ports.
Step 2. Provide an FC topology for the converted ports. For example, convert any switches from iSCSI to
FC.
Step 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.
