On Critical Reliability systems (duplicated PNC),
set pnc lock
locks the active
port network connectivity in the active state. PNC interchanges will be prevented
and the active port network connectivity will remain active regardless of its state
of health. Duplicate call setup will still take place, though the standby is not
available for service. This condition can also be initiated by the
reset pnc
interchange override-and-lock
command. You can tell if the PNC is locked by
looking at the
Software Locked?
field on the
status pnc
screen. (The
Interchange Disabled?
field refers to the antithrashing mechanism.)
Set pnc unlock
releases the lock and enables subsequent interchanges to take
place.
If the health of the active pnc has degraded to worse than that of the standby
pnc, unlocking the active port network connectivity can cause an immediate PNC
interchange This condition can be foreseen by use of
status pnc
.
System restarts remove a PNC lock.
!
CAUTION:
If the active PNC experiences problems while in the locked state, service
disruptions may occur that would ordinarily be avoided by PNC
interchange.
