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 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.
摘要:
To provide a technique whereby a user can carry out operations in the same operating environment, regardless of whether the user uses a computer inside a network system, or uses a terminal outside the network system. A network system comprises: a first computer used by a designated user; and a plurality of second computers capable of being shared by a plurality of users. A management device, if a storage device is utilized by the first computer, allows the first computer to connect to a designated storage area and execute the boot-up program stored therein. The management device, if the storage device is utilized by an external terminal used by the designated user, allows one designated computer selected from the plurality of second computers to connect to the designated storage area and execute the boot-up program, and allows the external terminal to connect to the designated computer.
