Abstract
A storage control device includes a processor. The processor is configured to acquire, when a first fault has occurred in a first storage device, first storage data to be used in recovery of the first storage device from a plurality of first storage control devices. The processor is configured to derive, when a second fault has occurred in a second storage device controlled by a second storage control device, first processed data from the first storage data. The first processed data is to be used in recovery of the second storage device. The processor is configured to notify the second storage control device of the first processed data.
Claims7
A storage control device, comprising:
- a processor configured to
- acquire, when a first fault has occurred in a first storage device, first storage data to be used in recovery of the first storage device from a plurality of first storage control devices,
- derive, when a second fault has occurred in a second storage device controlled by a second storage control device, first processed data from the first storage data, the first processed data being to be used in recovery of the second storage device, and
- notify the second storage control device of the first processed data.
A computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:
- acquiring, when a first fault has occurred in a first storage device, first storage data to be used in recovery of the first storage device from a plurality of first storage control devices;
- deriving, when a second fault has occurred in a second storage device controlled by a second storage control device, first processed data from the first storage data, the first processed data being to be used in recovery of the second storage device;
- and
- notifying the second storage control device of the first processed data.
A data recovery method, comprising:
- acquiring by a computer, when a first fault has occurred in a first storage device, first storage data to be used in recovery of the first storage device from a plurality of first storage control devices;
- deriving, when a second fault has occurred in a second storage device controlled by a second storage control device, first processed data from the first storage data, the first processed data being to be used in recovery of the second storage device;
- and
- notifying the second storage control device of the first processed data.
