# VTL Fibre Channel Port Configuration – Mode

Fibre Channel (FC) port configuration defaults to dual mode – Initiator and Target. This dual mode helps facilitate initial zoning setup.

Note

You must zone each FC port for each device type use - disk only or tape only.

Before you use FC port, set to proper use mode as outlined in the following table.

VTL 2.0 Port Mode | MediaAgent Host/Array/Filer FC Port
--- | ---
Target | Initiator Apply on MediaAgent host to detect and use VTL 2.0 tape devices. By default, FC OS drivers load in Initiator mode.
Initiator | Target VTL 2.0 uses array or filer providing a FC LUN as disk storage.
Target | Initiator, when NDMP filer or array uses VTL 2.0 emulated tape devices. Note: If NDMP filer is set in Initiator mode, you must perform filer reboot to properly set the mode. In cases where you set NDMP filer as Target and cannot change to Initiator mode, you must set VTL 2.0 side as Target.
