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. For instructions, refer to the
express configuration,
Option 2: Convert iSCSI hosts to FC
1. Shut down the iSCSI hosts connected to the ports you converted.
2. Provide an FC topology for these ports. For example, convert any switches connected to those
hosts from iSCSI to FC.
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.
4. Attach cables to the SFPs, and confirm they are connected to the correct FC switch or host.
5. Power on the hosts.
6. Use
Lenovo Storage Interoperation Center (LSIC)
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.
7.3.6. Complete FC/iSCSI to iSCSI conversion
If you previously had a combination of FC host ports and iSCSI host ports and you converted all
ports to iSCSI, you might need to modify your existing configuration to use the new iSCSI ports.
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 from FC to iSCSI.
Option 1: Remove FC hosts and add iSCSI hosts
1. If you are not already using dual-protocol SFPs, remove any FC SFPs, and replace them with
iSCSI SFPs or dual-protocol SFPs.
2. Attach new iSCSI hosts to these ports, either directly or by using a switch.
3. Configure iSCSI networking for the new hosts and ports. For instructions, refer to the
express configuration,
Windows express configuration, or
Windows express configuration, or
VMware express
to configure the FC hosts.
