Configuring the Fibre Channel port
Function of the ports
The FAS270/FAS270c CPU module provides two independent Fibre Channel ports, identified as 0b and 0c:
- You use the 0b port to communicate to internal and external disks.
- The 0c port has an external optical connector on the rear of the FAS270/FAS270c. You can configure the 0c port in one of two modes:
- You use initiator mode to communicate with tape backup devices, such as in a TapeSAN backup configuration.
- You use target mode to communicate with SAN hosts or a front end SAN switch.
Fibre Channel port 0c does not support mixed initiator/target mode. The default mode for port 0c is initiator mode. If you have not licensed the FCP service and you want to use port 0c in initiator mode, you do not need to configure the port.
FAS270c cluster configurations
FAS270c cluster configurations must be cabled to switches that support public loop topology. To connect a FAS270c to a fabric topology that includes switches that only support point-to-point topology, such as McDATA Director class switches, you must connect the cluster to an edge switch and use this switch as a bridge to the fabric. For information about specific switch models supported and fabric configuration guidelines, see the FCP/iSCSI Configuration Guide at http://now.netapp.com/NOW/ knowledge/docs/san/fcp_iscsi_config/.
Configuring port 0c for target mode
To configure the external Fibre Channel port 0c for target mode, complete the following steps.

Enable the FCP license by entering the following command:
license add FCP_code
FCP_code is the FCP service license code provided to you by NetApp.
Example
fas270a> license add XXXXXXX
A fcp site license has been installed.
cf.takeover.on_panic is changed to on
Run 'fcp start' to start the FCP service.
Also run 'lun setup' if necessary to configure LUNs.
A reboot is required for FCP service to become available.
FCP enabled.
