160.3.1 EXECUTE-REST

The following actions are possible:
a)
Conditional restart of an SWU
These actions are tested as to their executability.
1.
Soft restart with switchover (duplex soft restart):
Reset and booting (hard restart) of the active controller half, assuming that the partner controller is able to soft restart (i.e. is in STANDBY), otherwise output of an error message. The partner controller then becomes the ACTIVE processor via a soft restart.
2.
Soft restart without switchover (simplex soft restart):
The active processor is reset and restarted, if the partner processor is either not present or not restartable (i.e. not in standby state). The AMO checks that the active processor is restartable (fault analysis state ACTIVE).
Although both types of restart are possible, the AMO itself treats all soft restarts as simplex restarts. The type of restart to be initiated is decided by the dependability check.
b)
Unconditional action
Unconditional actions are actions carried out without consideration of dynamic module states. However, such an action is possible only if the unit as a whole is READY. The system dependability determines the appropriate action in all cases.
1.
Unconditional reset and booting of a controller half:
A controller is reset and makes a hard restart.
2.
Reload (only for loadable redundant units CC and LTG):
An unconditional reset is made, together with reloading of code and static data as well as booting.
3.
System restart:
An unconditional reset and booting/restarting of all system controllers (all SWU processors hard restart and all servers, soft restart) is carried out.
c)
Server restart
A prerequisite for a server restart is that the server be in service. Any escalation to another level is determined by SYSLOAD, independent of the system dependability (hence not a conditional action). The actual restart level can be read from the resulting error message.
In a monoprocessor system the server A1 can be restarted only by restarting the SWU.
d)
System restart:
Unconditional reset, reloading of code and static data, and booting of all system controllers. The loading device can be assigned to the standard device HD, to the alternative device such as MO or to :GLA: on HD containing the rescue SW.
Gold Load Area:
The gold load area will contain a particular software maintenance release (SMR).
In the fall back situation, where the system escalated to the gold load area, an alarm to the service center has to be generated.
e)
Restart/Reload of 80CMX-DSC Coprocessor
The new DSC processor board with its Motorola coprocessor can be restarted too. This coprocessor can not be soft-restarted. The parameter COPRO will be ignored if the switch has no DSC coprocessor or if both the parameter PRSTATE and the parameter COPRO parameter is entered.
Notes
STANDBY means, in the case of duplicated processors, that the particular processor concerned is in a position to soft restart at any time, but inactive. ACTIVE means that the particular controller’s hardware is functional and is in service.
