AM
– AM: The activity monitor that detects whether or not there is a request for data
from the initiator at regular intervals. If AM detects a time-out, the P-JNL state will
be changed from P-JNN to PJSE.
Note: The same path information is used for AP for three commands (pairvolchk,
pairdisplay, raidvchkscan). The differential is that pairvolchk and pairdisplay are to
show a special meaning with SSUS(SSWS) state.
Q-Marker: Displays the sequence # of the journal group ID, called the Q-marker. For
P-JNL, Q-Marker shows the latest sequence # on the P-JNL volume. For S-JNL, the
Q-Marker shows the latest sequence # of the cache(DFW).
