Abstract
A disk array apparatus includes a conversion rule storage unit that stores a conversion rule associated with a plurality of generations in a configuration table of the disk array apparatus and a control unit that, from a disk device which stores a generation identifier indicating the generation and a configuration table, retrieves the generation identifier, and converts the configuration table on the basis of the conversion rule associated with the retrieved generation identifier.
Claims7
A disk array apparatus comprising:
- a conversion rule storage unit that stores a conversion rule associated with a plurality of generations in a first configuration table of the disk array apparatus;
- and
- a control unit that, from a disk device which stores a generation identifier indicating the generation and a second configuration table, retrieves the generation identifier, and converts the second configuration table on the basis of the conversion rule associated with the retrieved generation identifier,
- wherein
- the second configuration table includes an option for a type of the disk device, and
- the control unit adds a new type of disk device and an associated flag which indicates that the type is not selected as the new option for the type of the disk device in the second configuration table.
A control method for a disk array apparatus, comprising:
- storing a conversion rule associated with a plurality of generations in a first configuration table of the disk array apparatus;
- from a disk device which stores a generation identifier indicating the generation and a second configuration table, retrieving the generation identifier, and converting the second configuration table on the basis of the conversion rule associated with the retrieved generation identifier, the second configuration table including an option for a type of the disk device;
- and
- adding a new type of disk device and an associated flag which indicates that the type is not selected as the new option for the type of the disk device in the second configuration table.
A computer readable non-transitory storage medium embodying a program, said program causing a disk array apparatus to perform a method, said method comprising:
- storing a conversion rule associated with a plurality of generations in a first configuration table of the disk array apparatus;
- from a disk device which stores a generation identifier indicating the generation and a second configuration table, retrieving the generation identifier, and converting the second configuration table on the basis of the conversion rule associated with the retrieved generation identifier, the second configuration table including an option for GP a type of the disk device;
- and
- adding a new type of disk device and an associated flag which indicates that the type is not selected as the new option for the type of the disk device in the second configuration table.
