LILP: Loop AL_PA position map.
The AMS200 transmits LIP first. When LIP is detected by the AMS200, the array controller
transmits LISM. When the same LISM as the AMS200 has transmitted is received at the array
controller, the subsystem becomes a Loop Master, and the subsystem transmits and receives
ARBx, LIFA, LIPA, LIHA, LISA, LIRP, and LILP with address map, and determines the AL_PA of
each L_Port. At the end of the Loop Initialization, the subsystem transmits and receives CLS.
When the AMS200 does not become a Loop Master, the transmission of LIFA, LIHA, LISA, LIRP,
and LILP are initiated by the Loop Master. The AMS200 receives bit map information, and
may add own AL_PA, and transmits it to the next L_Port. At the end of the Loop
Initialization, the subsystem receives and transmits CLS.
