The storage system includes a controller receiving a plurality of access commands from a plurality of host computers, a plurality of disk drives being coupled to the controller, and a panel adapted to display host group identifiers and logical storage regions so that security information can be set for a logical storage region by a user on a host computer basis or on a host group basis.

Method and apparatus for controlling access to storage device

The storage regions under command of a storage controller can be simply enabled and disabled to access to by automatically registering connected host computers. Such system can be achieved by taking a step of acquiring N_Port_Name information included in a login frame from the host computers, and a step of displaying a table of access right of host computers to a logical unit under command of storage controller. A security table for the storage controller can be generated by supervisor's setting the access enable/disable flag information.

In a storage system having a plurality of disk array devices connected through a network to a host for running an application, and a management server for monitoring the disk array devices, the disk array device includes a physical disk error detecting unit for detecting an error in a physical disk. Meanwhile, the management server stores a corresponding relationship among the application, a logical volume used by the application, and the physical disk corresponding to the logical volume. Moreover, the management server includes an application detecting unit for detecting the application using the logical volume corresponding to the physical disk with the error according to the corresponding relationship when the physical disk error detecting unit of the disk array device detects the error in the physical disk.

Storage system, management server, and method of managing application thereof

The storage regions under command of a storage controller can be simply enabled and disabled to access to by automatically registering connected host computers. Such system can be achieved by taking a step of acquiring NPortName information included in a login frame from the host computers, and a step of displaying a table of access right of host computers to a logical unit under command of storage controller.
