Figure 1.42 Extended link service (loop initialization)

Listed below are the frames used by Loop Initialization in the Extended Link

Service supported by this drive.

1. LISM frame: Used for selecting Loop Master.

2. LIFA, LIPA, LIHA, LISA frame: Used to assign AL_PA in Loop

Initialization.

3. LIRP, LILP frame: Used for collection and notification of connection

information for the initiator and drive connected on the loop.

The header field of Extended Link Service is defined below.

(1) R_CTL.. (Routing Control)

The high order 4 bits (2h) represent Extended Link Service, and the low order

4 bits (2h) Initialization frame.

(2) D_ID.. (Destination Identifier)

0000EFh: In the case of NL_Port

000000h: In the case of FL_Port

(3) S_ID.. (Source Identifier)

0000EFh: In the case of NL_Port

000000h: In the case of FL_Port
