Abstract
A method for operating a mirrored disk storage system, comprises a determiner component for determining a repair characteristic of a pair of mirrored disks, a comparator for comparing said repair characteristic of a first of said pair with said repair characteristic of a second of said pair, and a cancelling component for cancelling a repair action for said one of said first or said second of said pair that is not selected by said selector.
Claims16
A method of operating a mirrored disk storage system, comprising the steps of:
- determining a repair characteristic of at least a pair of mirrored disks;
- comparing said repair characteristic of a first of said pair with said repair characteristic of a second of said pair;
- and
- cancelling a repair action for said one of said first or said second of said pair that is not selected by said selector.
An apparatus for operating a mirrored disk storage system, comprising:
- a determiner component for determining a repair characteristic of a pair of mirrored disks;
- a comparator for comparing said repair characteristic of a first of said pair with said repair characteristic of a second of said pair;
- and
- a cancelling component for cancelling a repair action for said one of said first or said second of said pair that is not selected by said selector.
A physical computer non-transitory storage medium comprising a computer program product method for operating a mirrored disk storage system, the physical computer non-transitory storage medium comprising:
- computer code for determining a repair characteristic of at least a pair of mirrored disks;
- computer code for comparing said repair characteristic of a first of said pair with said repair characteristic of a second of said pair;
- and
- computer code for cancelling a repair action for said one of said first or said second of said pair that is not selected by said selector.
