9.0 Interface requirements
This section partially describes the interface requirements as implemented on ST118273FC drives. Additional
information is provided in the
Fibre Channel Interface Manual
(part number 77767496).
9.1 FC-AL features
This section lists the Fibre Channel-specific features supported by ST118273FC drives.
9.1.1 Fibre Channel link service frames
Table 3 lists the link services supported by ST118273FC drives.
9.1.2 Fibre Channel task management functions
Table 4 lists the Fibre Channel SCSI Fibre Channel Protocol (FC SCSI FCP) task management functions sup-
ported.
9.1.3 Fibre Channel task management responses
Table 5 lists the FC SCSI FCP response codes returned for task management functions supported.
Table 3: Link services supported
