摘要:
For a computer system that includes a storage system and a management computer, the storage system includes a first storage area, for storing data used by a computer connected to the storage system, and a second storage area, for storing a duplicate of the data included in the first storage area. The management computer includes first management information, for managing the frequency at which the data in the first storage area are copied. When the management computer receives a notification indicating the first storage area has been unmounted from another computer, the management computer employs the first management information for determining whether the data in the first storage area should be copied. Then, when the data should be copied, the first storage area is mounted on the computer and the data in the first storage area are copied to the second storage area.

A management device selects a storage device having a plenty of unallocated storage regions, selects a target using a port having a small allocation quantity from the storage device targets, and allocates the target, an initiator, and a storage region. When the number of targets and the allocated storage regions prepared by the storage device is within a predetermined number, the storage device manages the storage device as an allocation candidate. When the predetermined number is exceeded, the exceeding one is excluded from the allocation candidate. When the number of storage devices excluded from the allocation candidate has reached a certain number, the management device manages a new storage device and a new storage region as an allocation candidate.

The storage system creates a volume for storing information specific to a user, and a volume for storing software shared by a plurality of users, links these volumes on the basis of the software usage status of the users, and virtually builds one region and supplies same to the users.

A computer 10a stores boot information OA1 and application information AP1 stored on a local disk 16a, the information being respectively stored as an OS1 shared file group in a shared LU1 and as a AP1 shared file group in a shared LUn+1. For personal information (including personal information of boot information or AP information), computer 10a stores the information as a user personal file group in an personal LU1. Computer 10a transmits image outline information, LU information and file information for the sets of information stored in shared LU1, shared LUn+1 and personal LU1 to an disk-image management server 30, where the information is stored in the storage device 31 of the disk-image management server 30.

The management and reliability of communications between computers and a storage system are improved. As between the primary and secondary communication ports of storage devices 20a, 20b, the system management server 10 sets the primary communication port as the current communication port as a default setting in each storage device. Where the system management server 10 monitors the primary and secondary communication ports and the current communication port fails or can otherwise no longer be used, the other communication port is set as the current communication port. The system management server 10 also manages the states of each communication port and the setting of the current communication port as communication port information.

The system management server 10 makes a request to the virus detection and removal server 30 for virus detection processing on a specified primary volume of the storage system 20. The virus detection and removal server 30 executes virus detection processing on the requested primary volume and the secondary volume that forms the volume pair at the storage system 20. Even during virus detection processing on the storage system 20, it is possible for the centric PCs 40 and 42 to continue write and read processing on the requested primary volume.

A diskless computer is allowed to finish a write request with no influence of a storage device and a network of the storage device. A node device 104 passes on information sent and received between a diskless computer 101 and a storage device 102. When information sent from the diskless computer 101 is a write request to the storage device 102, target data of the write request is cached, and a response to the write request is sent to a source diskless computer of the write request. The write request for the data having been cached is sent to a storage device into which the data is written, and a response to the write request is received from the storage device.

A computer system includes: means for centrally managing user identification names and passwords that are assigned to users, target names of storage devices, addresses, and logical units; means for acquiring target names of storage devices and logical unit names from the user identification names and passwords; means for obtaining the addresses of the storage devices from the user identification names, passwords, and target names; and means for dynamically creating access control information of the logical units for each session in iSCSI session establishment processing.

A computer system uses a virus-scan method capable of full-scanning the logical volume of a SUTOSEN PC with high frequency while limiting the number of virus-scan devices. The computer system includes a primary volume storing data from a personal computer, a snapshot volume storing the status of the primary volume at a given point in time, and a save destination volume storing an updated memory area within the primary volume as information on an updated block address reflected in a bitmap. The updated block address corresponds to a memory area within the primary volume. The computer system detects only an updated file in the primary volume from the snapshot volume and the save destination volume, creates an updated volume for storing a relevant updated file, and thereby executes a virus-scan on the updated volume.
