Command Processing
2-26 C141-C008
The start of execution timing for this automatic readjustment
operation is ordinarily impossible for the INIT to predict. The
automatic readjustment operation is performed when there is no
command being executed or waiting in the queue, but execution of
commands issued immediately after the IDD starts a readjustment
operation is caused to wait until the readjustment operation is
completed.
2.7.6 Reset processing
Reset measures which can be performed by the INIT on the FC Loop are as
shown below.
• LIP
• TARGET RESET
• CLEAR TASK SET
• ABORT TASK SET
• ABTS

An outline of each processing operation is shown below.
(1) LIP
LIP is a primitive defined by FC-AL, and by this primitive appearing in multiple
loops, the loop initialization sequence for ALPA acquisition is implemented.
Generally, there are 3 types of LIP.
1. LIP (F7, F7): LIP that is output when ALPA is not fixed.
2. LIP (ALPD, ALPS): LIP that is output when the ALPS (transmission source)
desires to reset the ALPD (transmission destination) device.
