摘要：
A data storage system in which system activation is performed in cooperation with two host systems sharing a data storage system. A determination unit determines which of the two host systems makes access to the data storage system. A system access control unit controls access to the data storage system from the host systems to prevent competition between the host systems. Each of the host systems indicates completion of system activation to the other host system.
