Maintenance Commands
Feature Interactions
System Restarts
An upgrade causes a system restart: simplex systems perform a Level-4 restart,
and duplex systems perform a Level-2 SPE-interchange after the standby is
upgraded through a Level-4 restart.
Initcauses
Use display initcauses to see the software upgrade and the system reset level.
Multi-User Contention
When this command is executing, all other maintenance commands are blocked.
Exceptions to these are most of the status or display commands. All
administration commands are not blocked. It is the user's responsibility to make
sure that no new translations are added between the last save translation
operation and the completion of the upgrade software command.
Recent Change History Log
The upgrade software command is not logged for both simplex and duplex
systems. This is due to the clearing of memory during the level 4 reset.
Periodic and Scheduled Maintenance
Periodic and scheduled maintenance is suspended during the upgrade.
Error and Alarm Log
Error and alarm logs before the software upgrade are lost.
Demand Busyout Objects
Maintenance objects that have been demand busyout are released when the
processor reboots or interchanges during the software upgrade. If the command
is cancelled before the actual reboot or interchange starts, then all demand
busyout objects status are preserved.
Data Consistency between SPEs
Data consistency alarms are generated if the software in the active and standby
SPE are not consistent.
