FS

Receive buffer field size. The FS field in the common and Class 3 parameters is checked for the range 128 < FS < 2,112 and a

 

multiple of four bytes. For multiple frame sequences, all frames but the last frame of the sequence must be this size. Only the

 

receive buffer field size in the Class 3 parameters is used.

PN

Port name (initiator’s)—saved with the login parameters. If a change of the port name/AL_PA address association is detected

 

during a Port DISCovery, and implicit logout occurs and the initiator returns a LS_RJT.

NN

Node name. The node name is not checked or saved by the drive.

SO

Service options Class 3 only.
