PURPOSE:To execute the minimum necessary precaring and to eliminate the delay of rise of a subsystem by executing the precaring of the subsystem in response to execution of the precaring of a host system. CONSTITUTION:When a host system decides that the precaring must be executed, '1' set to an execution flag 1 for execution of the precaring. While '0' is set to the flag 1 when the host system decides that no execution of the precaring is needed. While a subsystem receives a loading request from the host system together with the information on a control block including '1' or '0' of the flag 1 and extracts the flag 1 out of the control block. An initial diagnosis discriminating part 2 decides whether the precaring should be executed or not for the extracted flag 1. Then the precaring of the subsystem is carried out when the flag 1 is equal to '1' for example. |
