A volume management system, a managing computer, a host, and a volume management method being capable of regulating the authorities of users and avoiding misoperations are provided. The volume management system comprises a storage having volumes served as a storage region, a managing computer, and a plurality of hosts used by users obtaining an operation authority over the volume. Two or more users can use an identical volume. Upon obtaining an operation content of one user for at least one of the volumes over which two or more users have the operation authority, the managing computer determines from an attribute of the volume and the operation authority of the two or more users over the volume whether the operation content is executable. When the operation content is not executable, the operation content is restrained.
A computer system comprising:
A managing computer for managing at least one storage having one or more volumes served as a storage region, two or more users being capable of obtaining and using an operation authority over an identical volume, wherein upon obtaining an operation content in a host computer used by one user for at least one of the volumes over which two or more users have the operation authority, the managing computer determines from an attribute of the volume and the operation authority of the two or more users over the volume whether the operation content is executable, and when the operation content is executable, the operation authority of the other users over the volume is changed depending on the attribute of the volume.
A host computer for use by a user capable of obtaining and using an operation authority over an identical volume in a storage with other users, the storage having one or more volumes served as a storage region, wherein when the user executes an operation on the volume in the storage, and when a managing computer for managing the storage determines from an attribute of the volume and the operation authority of two or more users over the volume whether the operation content is executable, the host computer displays whether the operation on the volume is available.
A volume management method in a computer system including at least one storage having one or more volumes served as a storage region, a managing computer for managing the storage, and a plurality of host computers, each host computer being used by a user capable of obtaining an operation authority over the volume in the storage, where the storage, the managing computer, and the host computers being interconnected via a network, and two or more users being capable of using an identical volume, the method comprising the steps of:
