Demand test descriptions and error codes
There are no demand tests for EXP-PN. Two reset tests, PN Cold Restart Test (#955) and PN
Warm Restart Test (#956) can be executed to reset a PN.
The PN Warm Restart Test (#956) restarts a PN that has not been taken out of service. It is the
least severe of the PN restart levels and is used in an attempt to preserve the state of the
system as much as possible, thereby reducing user impact. The command for this type of
restart is reset port-network P level 1 where P is the port network number.
The PN Cold Restart Test (#955) is used as a recovery mechanism for a PN that has been
taken out of service. It is executed as a result of PN recovery escalation when a Warm Restart
is not possible, or as a result of a system technician demanded PN restart. Once a PN has gone
out of service, a PN Cold Restart is required to bring it back into service. This is the most severe
of the PN restarts, and users will experience a service outage. The command for this type of
restart is reset port-network P level 2 where P is the port network number.
