Abstract
Log manipulation by a first administrator is prevented so that the reliability of system auditing can be improved.
After receiving a service start request from a management computer, a storage subsystem creates a first resource group regarding which access by a host computer is permitted, and also creates a second resource group regarding which access by the management computer is permitted. The storage subsystem further creates a data storage area, to which data is to be written by the host computer, and makes the data storage area belong to the first resource group, while it also creates a log storage area, in which log information indicating past operation performed on the data storage area by the host computer is to be recorded, and makes the log storage area belong to the second resource group.
