AM: The activity monitor that detects whether or not there is a request for data

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.

P-JNL, Q-Marker shows the latest sequence # on the P-JNL volume. For S-JNL, the
