Table 38:LS_RJT reason code explanations
17.3.3 Port Login (PLOGI)PLOGI is used by the Initiator to register Service Parameters with the Target if Implicit Login is not being used (see 19.10.12,
“Mode Page 19h (Fibre Channel Port Control Page)” on page 190). The Target responds with an LS_ACC that has a payload
similar to the PLOGI but which contains the Targets parameters. This exchange of parameters establishes the operating envi-
ronment between the Initiator and the Target.
PLOGI can also be issued by the Target when it is operating as a Public Loop Device. In this case, the Target uses a PLOGI to
establish the operating environment between it and the Fabric Name Server.
Bytes 1, 2, and 3, of the payload must be set to zeros. Otherwise, the drive will respond with an LS_RJT containing a reason
code of “Command not supported”, and a reason code explanation of 00h “No additional explanation”.
