Table 1.19 LIP sequences
LIP type Use Description
LIP (F7, F7)
LIP (F7, AL_PS)
Initializing
Loop
A NL_Port requests to obtain AL_PA *1
LIP (AL_PD, AL_PS) Reset the port The source port (AL_PS) requests to reset
the destination port (AL_PD).
The selected port performs to reset after
loop initialization.
*2
LIP (F8, AL_PS) Loop failure The NL_Port has detected an input failure
AL_PS is the AL_PA of the source port.
*1
LIP (F8, F7) Loop failure The NL_Port has detected an input failure
and the port could not obtain an AL_PA.
*1
LIP (FF, AL_PS) Reset ALL
port
A Vendor Specific reset executes for both
port.
Note:
*1: The drive can issue the LIP.
*2: The drive receives the LIP but does NOT issue LIP (AL_PD, AL_PS).
(4) LISM (Loop Initialization Select Master)
This sub-section describes a process to select the loop master to which the
function for proceeding with each process of Loop Initialization is given.
Selecting the loop master proceeds as follows. (Figure 1.11)
Figure 1.11 shows the example that three ports exist on the loop and each port has
an unique Port Name which algebraic relationship is n+2>n+1>n.
Steps [1] through [6] are for selecting a port with the smallest unique port name
of those assigned at manufacture, as the loop master.
Steps [8] and [9] are for confirming that the port, which became the loop master
by steps [1] through [6], has become the loop master again.
