Fibre Channel Connections

This section explains how to set up the server to connect the tape library by using a Fibre Channel connection.
(1) Install the driver and set up the Fibre Channel card.
For details about how to install the driver and set up the Fibre Channel card, refer to the manual that is
provided with each Fibre Channel card.
Fixing the target ID
The target ID is assigned to a device which connects to the Fibre Channel card. By default, the target ID is
automatically set by the driver. Therefore, the assigned target ID of the device may be changed when
adding or removing devices. It may also be changed based on the state in which the device is recognized.
If the target ID is different before and after rebooting the server, depending on the OS and application,
the device may go off-line and become unavailable. To avoid this, setting the fixed target ID to each
device is recommended.
(2) Check the devices.
