Abstract
An aspect includes receiving a drive log page including data from a plurality of disk devices, in which the drive log page includes a plurality of attribute fields including a reassignment field that tracks data movement from a failing sector of a disk device to a new sector of the disk device. Performing, by the system, a failure prediction based on attribute data of the drive log page to identify one or more disk devices of the plurality of disk devices that are predicted to fail. Disabling, by the system, the one or more disk devices in response to the failure prediction.
Claims20
A computer-implemented method comprising:
- receiving, by a system comprising one or more processors, a drive log page including data from a plurality of disk devices, wherein the drive log page includes a plurality of attribute fields including a reassignment field that tracks data movement and pending data movement from a failing sector of a disk device to a new sector of the disk device, the pending data movement including pending reassigns that occur when the failing sector of the disk device has been identified and prior to receiving new data for storage at the new location;
- performing, by the system, a failure prediction based on attribute data of the drive log page to identify one or more disk devices of the plurality of disk devices that are predicted to fail;
- and
- disabling, by the system, the one or more disk devices in response to the failure prediction, the disabling comprising electronically removing access to the one or more disk devices.
A system comprising:
- a memory having computer readable instructions;
- and
- one or more processors for executing the computer readable instructions, the computer readable instructions controlling the one or more processors to perform operations comprising:
- receiving a drive log page including data from a plurality of disk devices, wherein the drive log page includes a plurality of attribute fields including a reassignment field that tracks data movement and pending data movement from a failing sector of a disk device to a new sector of the disk device, the pending data movement including pending reassigns that occur when the failing sector of the disk device has been identified and prior to receiving new data for storage at the new location;
- performing a failure prediction based on attribute data of the drive log page of the plurality of disk devices to identify one or more disk devices that are predicted to fail;
- and
- disabling the one or more disk devices in response to the failure prediction, the disabling comprising electronically removing access to the one or more disk devices.
A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by system comprising one or more processors to cause the system to perform operations comprising:
- receiving, by the system, a drive log page including data from a plurality of disk devices, wherein the drive log page includes a plurality of attribute fields including a reassignment field that tracks data movement and pending data movement from a failing sector of a disk device to a new sector of the disk device, the pending data movement including pending reassigns that occur when the failing sector of the disk device has been identified and prior to receiving new data for storage at the new location;
- performing, by the system, a failure prediction based on attribute data of the drive log page to identify one or more disk devices of the plurality of disk devices that are predicted to fail;
- and
- disabling, by the system, the one or more disk devices in response to the failure prediction, the disabling comprising electronically removing access to the one or more disk devices.
