Feature Interactions
■ The reset command invokes system initialization like low level
maintenance. Software never escalates requested reset levels.
Technicians determine the levels.
■ Two hardware switches are associated with active and standby SPEs.
These hardware switches override demand maintenance activities
requested by system technicians. If active SPEs are locked active with
these hardware switches, interchanges do not occur until the active is
unlocked.
■ Successful SPE interchanges logoff PPNSAT terminals.
■ Restart levels null the effect of the health-override option.
PI-BD MAJOR or MINOR ON 20 Hot
PKT-CTRL MAJOR ON or OFF 20 Hot
PKT-CTRL MINOR ON or OFF 15 Hot
PI-PT MAJOR ON 15 Hot
DATA-CHL MINOR ON 15 Hot
DATA-CON MINOR ON 15 Hot
DATA-BD MINOR ON 15 Hot
MEM-CARD MINOR ON or OFF 10 Hot
PR-MAINT MINOR OFF 8 Hot
A reset system interchange command aborts if:
■ The standby SPE is down
■ The active SPE is locked active
■ Communication to the standby SPE is not possible
■ Memory shadowing to the standby SPE is not functioning
■ The standby SPE is not fully refreshed
■ The standby SPE is busied out
health-
override
If HOT restart interchanges fail because Fault Severity Levels of
standby SPEs are higher than active SPEs, the health-override
command tries to force a switch. If the switch occurs, new active SPE
Fault Severity Level raises to prevent a software-initiated HOT SPE
interchanger. This artificial raising of active Fault Severity Levels lasts
for one hour, then Fault Severity Levels of both SPEs returns to their
normal values.
