PURPOSE:To save the data restoring time and to keep the reliability by inhibiting the use of a unit section only from the result of the diagnosis of a failure range, copying the content of the normal volume after the restoration of a failure and using it again. CONSTITUTION:If an input/output failure takes place, the error restoration processing is failed, and if the failure in a volume section is doubtful, a failure restoration processing section 9 starts a physical volume failure diagnostic processing section 10. The started section 10 performs the processing of failure diagnosis and if the failure is a partial failure, a physical volume section close processing section 11 is started. The section 1 records the closing information to a close information area 6 on a main storage device (MM) and to a prescribed area of full physical volumes 2-1-2-n. If the partial failure restoration is executed, the closing release processing section releases the closing state. |
