ABSTRACT:
An information processing system and a logout process therefor wherein when an error takes place in a storage control unit the storage control unit is inhibited from receiving storage access requests from other processing units such as basic processing unit and I/O processing unit and the error is reported to a maintenance control unit, the said other processing units are inhibited from performing time-out detecting operation, internal information of the storage control unit at the time when the error takes place is fetched therefrom and stored in the maintenance control unit, then the inhibition of the storage access request reception and the inhibition of the time-out detecting operation are removed, and the internal information is transferred from the maintenance control unit to a certain memory for later analysis of the error.
