Step 4.
Attach cables to the SFPs in the converted ports, and confirm they are connected to the correct FC
switch or host.
Step 5.
Power on the hosts.
Step 6.
Configure the FC hosts.
Step 7.
Edit the host partition to add the FC host port IDs and remove the iSCSI host port IDs.
Step 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 (h h o o t t _ _ a a d d d d and S S M M d d e e v v i i c c e e s s ). 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 FC/iSCSI to FC conversion

If you previously had a combination of FC host ports and iSCSI host ports and you converted all ports to FC,
you might need to modify your existing configuration to use the new FC ports.
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 ports 1 and 2 from iSCSI to FC.
Option 1: Remove iSCSI hosts and add FC hosts
Step 1.
If you are not already using dual-protocol SFPs, remove any iSCSI SFPs, and replace them with FC
SFPs or dual-protocol SFPs.
Step 2.
If you are not already using dual-protocol SFPs, remove any FC SFPs.
Step 3.
Attach new FC hosts to these ports, either directly or by using a switch
Step 4.
Configure FC networking for the new hosts and ports.
Option 2: Convert iSCSI hosts to FC
Step 1.
Shut down the iSCSI hosts connected to the ports you converted.
Step 2.
Provide an FC topology for these ports. For example, convert any switches connected to those
hosts from iSCSI to FC.
Step 3.
If you are not already using dual-protocol SFPs, remove the iSCSI SFPs from the ports, and replace
them with FC SFPs or dual-protocol SFPs.
Step 4.
Attach cables to the SFPs, and confirm they are connected to the correct FC switch or host.
Step 5.
Power on the hosts.
Step 6.
Configure the FC hosts.
Step 7.
Edit the host partition to add the FC host port IDs and remove the iSCSI host port IDs.
Step 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 (h h o o t t _ _ a a d d d d and S S M M d d e e v v i i c c e e s s ). These utilities help register the volumes with the hosts and
