本标准定义了SCSI光纤通道协议（FCP）的第二个版本。这是一个标准 用于将SCSI命令集应用于光纤通道的映射协议。本标准定义了光纤 通道服务和定义信息单元（IUs）用于执行 SCSI-3体系结构模型2（SAM-2）。第二个版本包括对第一个版本的补充和澄清 版本，删除现在包含在其他标准中的信息，并描述其他错误 光纤通道协议的恢复功能。

This standard defines a second version of the SCSI Fibre Channel Protocol (FCP). This standard is a mapping protocol for applying the SCSI command set to Fibre Channel. This standard defines how the Fibre Channel services and the defined Information Units (IUs) are used to perform the services defined by the SCSI-3 Architecture Model - 2 (SAM-2). This second version includes additions and clarifications to the first version, removes information that is now contained in other standards, and describes additional error recovery capabilities for the Fibre Channel protocol.
