without interrupting system. On such system, the only way to get the
system to work normally is to restart sysmgr.

Fibre Channel (FC) target ports will register new node and port
symbolic information starting in 3.1.2.
node/port symbolic information
65906
Node symbolic information is of the form:
Legacy systems: HP_3PAR 7000 <model>-<serial>-fw:<release>
7200 systems: HP_3PAR 7200 - <serial>-fw:<release>
7400 systems: HP_3PAR 7400 - <serial>-fw:<release>
where <model> is the legacy system model, such as V800; <serial>
is the system serial number, e.g., 1499607; and <release> is a four
digit number representing the HP 3PAR OS release and MU, e.g.,
3120 for 3.1.2 GA, 3121 for 3.1.2 MU1.
Port symbolic information is of the form:
<serial> - <n:s:p> — <type>
where <serial> is the system serial number, e.g., 1499607; <n:s:p>
is the location of the port, e.g., 1:3:2; and <type> is the type of the
HBA, eg., LPe12004.
Node and port symbolic information are registered with the FC fabric.
