> # Information About FLOGI

> In a Fibre Channel fabric, each host or disk requires an FC ID. If the required device is displayed in the FLOGI table, the fabric login is successful. Examine the FLOGI database on a switch that is directly connected to the host HBA and connected ports. See the "Default Company ID List" topic and the "Switch Interoperability" topic.
