    • A storage device which limits the partition of the logical memory devices for computers in accordance with the condition of partition which was defined to the properties such as reliability and the storage device so that the logical memory devices are unable to be utilized for uses other than objectives, a control method for partitioning the logical memory devices of the storage device and a control program product for partitioning the logical memory devices of the storage device. An access control means approves an access only to the logical memory device which was partitioned referring to an access control table. An access control setting means renews the access control table so as to partition the assigned logical memory devices to the assigned computer when the assigned logical memory devices can be partitioned. A utilization condition setting means determines the partition propriety of the logical memory device based the content of the partition condition defining table including a pair of the property condition which is the origin of judging whether the logical memory device can be partitioned or not and the partition propriety information of showing the propriety of partition to the computer and the content of the property table including a pair of the logical memory device ID and the property information of the corresponding logical memory device, and renews the partition management table.
    • 根据对诸如可靠性和存储设备等属性定义的分区条件,限制用于计算机的逻辑存储设备的分区的存储设备,使得逻辑存储器设备不能用于除目标之外的用途 ,用于划分存储装置的逻辑存储装置的控制方法和用于划分存储装置的逻辑存储装置的控制程序产品。 访问控制装置仅批准对参考访问控制表进行分区的逻辑存储设备的访问。 访问控制设置装置更新访问控制表,以便当分配的逻辑存储器设备可以被分区时,将分配的逻辑存储器设备分配给分配的计算机。 利用条件设置装置根据分区条件定义表的内容确定逻辑存储装置的分区合理性,该内容包括作为判断逻辑存储装置是否可分割的原点的属性条件对以及分区正确性 显示分配给计算机的适当性的信息和属性表的内容,包括一对逻辑存储器设备ID和对应的逻辑存储设备的属性信息,并更新分区管理表。
