AUTOMATIC mode supports unmanned operation. AUTOMATIC startup is used in conjunction with automatic system power-up following abnormal system termination when the automatic restart function is switched on. Its characteristics and logging correspond to the FAST mode.
AUTOMATIC mode may only be used if the SVP clock is functioning (omitted for restart) and the home pubset disks and paging disks are used only by this system.
In AUTOMATIC mode there are standard responses to certain exception conditions. This means that the operator is not required to make a decision. An example of a standard response is the automatic release of disks which are required but which are still locked as a result of an abnormal system termination.
Automatic restart is described in section “Automatic restart”.
The choice of startup type and the decision as to whether the user catalog is to be reconstructed depends on the values that have already been set for the system parameters STUPTYPE and RECONUC.

section “Selecting the startup type and catalog reconfiguration”.
