<p><b>New page</b></p><div>Wherein we configure the gateway between a Ceph RBD and a Fibre Channel LUN.<br />
<br />
Assumptions:<br />
* Fibre Channel fabric switch(es) are zoned appropriately<br />
* Gateway machine already has an RBD attached for use by the SCSI target subsystem<br />
* The gateway machine has a Qlogic HBA card installed and the module was given the <code>qlini_mode=disabled</code> or <code>qlini_mode=dual</code> arguments.<br />
* The initiator machine has an HBA that is not hardwired to target mode.<br />

At this point, there is a block device waiting to be attached to the SCSI target interface. So let's configure a target port, attach that backing device to the target port, and create an ACL that lets the client server see that LUN.<br />
