Abstract

PURPOSE:To inhibit an access given to a device to be tested from another host system by adding a flag showing a maintenance test mode of the device to be tested in a shared device to an inter-system shared DASD. CONSTITUTION:The host systems 1a and 1b give accesses in common to a shared device 3 consisting of an inter-system shared DASD 2 and a centralized large capacity memory CMSS. The DASD 2 contains a maintenance test mode display flag 21 set in response to plural memory units 3a forming the device 3 in the form of the control information against the device 3. The system 1a turns on (1) the flag 21 corresponding to the units 3a prior to the run of a maintenance test program 11. Then the system 1a runs the program 11 and turns off the flag 21 after the run of the program 11. In case the system 1b gives an access to the device 3 via a general program 12, the processing is carried out after the ON or OFF state of the flag 21 is confirmed. Thus it is possible to inhibit the access given from another host system during a test of the device 3.
