reset system [level# | interchange] [disk | tape] [contention-override]
!CAUTION:

All system resets (except plann ed interchanges) are servic e affecting, with

higher levels being inc reasingly destruc tive. Some resets may take up to

one half hour to complete. Certain c onditions may result in a higher rese t

level than the one requested. Unless you are exp erienced with resetting a

system, follow normal escalation p rocedures.

NOTE:
reset system interchange, used to switch c ontrol of the system from an
acti ve SPE to t he sta ndb y, is d isc ussed sep arate ly un der i ts own head ing.
This command resets a Switch Processing Element (SPE) at a specified level that
is increasingly disruptive as the reset level increases.

All system resets (except

reset system interchange) are disrup tive and terminate the G3-MT login.

When the command is entered, the MSS devices are c hecked to see if they are
currently in use. If any command or maintenance process that ac cesses the MSS
is in progress, the reset is denied and a message is d isplayed. In this c ase, the
contention-override option is required to forc e the reset. This check prevents
aborting of a save translation or other MSS proces s.
If the vector bit is set to trigg er a core dump for the specified reset level, a c opy
of system memory is first written to the primary M SS device. The system then
clears the vector and p roceeds with the request. If the vec tor is set for an active
SPE core dump for reset level 1 a reset level 2 will be per formed to recover the
Packet Interface links. See the get vector command.
System software will generally not escalate a demand system reset to a higher
level. There are certain conditions that result in a higher level reset than that
requested. These include the f ollowing:
■The vector is set to trigger a c ore dump on the active SPE in the event of a
level 1 reset.
■A PNC interchange is already in p rogress.
■A change in translation ad ministration is in progress.
Reset levels greater than 1 turn off shadowing in a d uplicated system, and leave
the standby SPE in an unrefreshed condition for several minutes.
