Abstract
A storage control apparatus can be connected to a higher level apparatus and a plurality of storage devices, and receives, from the higher level apparatus, a request to write into one of the plurality of storage devices. Here, if a storage device, among the plurality of storage devices, that has been specified as the access destination for the write request is not yet active, the storage control apparatus suspends the data involved in the write request, and writes the suspended data involved in the write request into the storage device once the storage device specified as the access destination is in a ready state.
Claims14
A storage control apparatus that can be connected to a higher level apparatus and a plurality of storage devices, the storage control apparatus comprising:
- a receiving unit that receives, from the higher level apparatus, a write request to any one of the plurality of storage devices;
- a suspending unit that suspends data corresponding to the write request in a case where a storage device, among the plurality of storage devices, that is specified as an access destination of the write request is not yet active;
- and
- a writing unit that, once the storage device specified as the access destination enters a ready state, writes the data corresponding to the write request suspended by the suspending unit into the storage device.
A control method of a storage control apparatus that can be connected to a higher level apparatus and a plurality of storage devices, the method comprising:
- receiving, from the higher level apparatus, a write request to any one of the plurality of storage devices;
- suspending data corresponding to the write request in a case where a storage device, among the plurality of storage devices, that is specified as an access destination of the write request is not yet active;
- and
- writing, once the storage device specified as the access destination enters a ready state, the suspending data corresponding to the write request into the storage device.
A computer-readable storage medium storing a computer program for causing a computer to execute a control method of a storage control apparatus that can be connected to a higher level apparatus and a plurality of storage devices, the method comprising:
- receiving, from the higher level apparatus, a write request to any one of the plurality of storage devices;
- suspending data corresponding to the write request in a case where a storage device, among the plurality of storage devices, that is specified as an access destination of the write request is not yet active;
- and
- writing, once the storage device specified as the access destination enters a ready state, the suspending data corresponding to the write request into the storage device.
