Option 1: Move FC hosts and add new iSCSI hosts
1. Move any FC hosts from the new iSCSI ports to the ports that remain FC.
2. If you are not already using dual-protocol SFPs, remove any FC SFPs.
3. Attach new iSCSI hosts to these ports, either directly or by using a switch.
4. Configure iSCSI networking for the new hosts and ports. For instructions, refer to the
express configuration,
Option 2: Convert FC hosts to iSCSI
1. Shut down the FC hosts connected to the converted ports.
2. Provide an iSCSI topology for the converted ports. For example, convert any switches from FC
to iSCSI.
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.
4. Attach cables to the SFPs in the converted ports, and confirm they are connected to the correct
iSCSI switch or host.
5. Power on the hosts.
6. Use
Lenovo Storage Interoperation Center (LSIC)
7. Edit the host partition to add the iSCSI host port IDs and remove the FC host port IDs.
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 (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.
7.3.4. 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.
