Add the iSCSI or FCP license, and start the target service. The Fibre Channel and iSCSI
protocols are licensed features of Data ONTAP software. If you need to purchase a license,
contact your IBM or sales partner representative.
Next, verify your cabling. See the FC and iSCSI Configuration Guide for detailed cabling and
configuration information at:

Configuring Fibre Channel HBAs and switches
Install and configure one or more supported Fibre Channel HBAs for Fibre Channel
connections to the storage system.
Attention: The Windows Host Utilities installer sets the required Fibre Channel HBA
settings. Do not change HBA settings manually.
1. Install one or more supported Fibre Channel HBAs according to the instructions provided
by the HBA vendor.
2. Obtain the supported HBA drivers and management utilities, and install them according to
the instructions provided by the HBA vendor.
3. Connect the HBAs to your Fibre Channel switches or directly to the storage system.
4. Create zones on the Fibre Channel switch according to your Fibre Channel switch
documentation.
Checking the media type of Fibre Channel ports
The media type of the storage system FC target ports must be configured for the type of
connection between the host and storage system.
The default media type setting of "auto" is for fabric (switched) connections. If you are
connecting the host's HBA ports directly to the storage system, change the media setting of
the target ports to "loop". This task applies to Data ONTAP operating in 7-Mode.
To display the current setting of the storage system's target ports, enter the following
command at a storage system command prompt:
fcp show adapter -v
The current media type setting is displayed.
To change the setting of a target port to "loop" for direct connections, enter the following
commands at a storage system command prompt:
fcp config adapter down
fcp config adapter mediatype loop
fcp config adapter up
adapter is the storage system adapter directly connected to the host.
Configuring iSCSI initiators and HBAs
For configurations that use iSCSI, you must either download and install an iSCSI software
initiator, install an iSCSI HBA, or both
An iSCSI software initiator uses the Windows host processor for most processing and
Ethernet network interface cards (NICs) or TCP/IP offload engine (TOE) cards for network
