The application provides a hard disk fault early warning method which is used for early warning hard disks which are likely to have faults.
Specifically, SMART information of the hard disk is obtained first, the SMART information includes a plurality of parameters of the hard disk, and the parameters of the hard disk can be represented to judge whether the hard disk fails. Judging whether the current value of the hard disk parameter exceeds the threshold value of the hard disk parameter, if the current value of one or more hard disk parameters exceeds the threshold value of the hard disk parameter, judging that the hard disk has fault risk, and generating alarm information with fault. If the current value of each hard disk parameter does not exceed the threshold value of the hard disk parameter, the hard disk needs to be evaluated next. And obtaining the comprehensive score of the hard disk according to the parameters of the hard disk, judging that the hard disk has fault risk when the comprehensive score of the hard disk is in the range of the fault risk of the hard disk, and generating alarm information with the fault.
According to the hard disk fault early warning method, operation and maintenance personnel are informed before the hard disk fails, the hard disk is prevented from being out of order and being alarmed again after loss is caused, and loss caused by data loss is reduced.
On the basis of the above-described embodiment:
as a preferred embodiment, the plurality of parameters includes at least two of a remapped sectors parameter, an uncorrectable error parameter, a currently to-be-mapped sectors parameter, an offline sectors parameter, and a command timeout parameter.
For a mechanical hard disk, the following five parameters may characterize the health of the hard disk: the method comprises the steps of correcting error parameters which cannot be corrected by the Reported unorderable Errors, remapping Sector parameters of the responded Sectors, Current Pending Sector parameters to be mapped currently, Sector parameters of Offline of Offline unordered Sectors, and Command Timeout parameters. According to the specific values of the five parameters, whether the hard disk has a fault or not can be judged subsequently.
In addition, the parameters include, but are not limited to, the above five, which are not limited herein.
As a preferred embodiment, acquiring SMART information of a hard disk includes:

As a preferred embodiment, acquiring SMART information of a hard disk includes:
SMART information of the hard disk is acquired periodically.
The conversion speed of each parameter of the hard disk is not high, so that the SMART information of the hard disk is periodically acquired, and energy can be saved.
As a preferred embodiment, after generating the alarm information of the hard disk with the failure risk, the method further includes:
and the control alarm module alarms the hard disk with the fault risk.
When the hard disk has a fault risk, generating alarm information of the hard disk with the fault risk, and informing operation and maintenance personnel that the hard disk has the fault risk. In addition, the alarm module can be controlled to alarm the hard disk with the fault risk, and operation and maintenance personnel can know the specific hard disk with the fault. The subsequent processing of the hard disk is facilitated.
As a preferred embodiment, deriving a composite score for a hard disk based on a plurality of parameters includes:
calculating the single score of each parameter as A C/B, wherein A is the current value of the parameter, B is the threshold value corresponding to the parameter, and C is the weight corresponding to the parameter;

and if the comprehensive score exceeds a preset score threshold, judging the fault risk of the hard disk, and generating alarm information of the hard disk with the fault risk.
Considering that the influence of each parameter on the hard disk is different, not only the current value of the hard disk parameter and the threshold value of the hard disk parameter but also the weight corresponding to the hard disk parameter need to be considered when the scoring is performed according to the parameters. And the individual scores of the parameters are A C/B, and the comprehensive score is the sum of the individual scores of the parameters.

And setting a scoring threshold, and if the comprehensive score exceeds the threshold, judging the hard disk has a fault risk. Specifically, if the score threshold is 60, the hard disk comprehensive score exceeds the score threshold, the hard disk has a failure risk, and alarm information of the hard disk with the failure risk needs to be generated.
In addition, the specific relationship between the composite score of the hard disk and the fault risk of the hard disk includes, but is not limited to, that the higher the composite score is, the greater the fault risk of the hard disk is, and the lower the composite score is, the greater the fault risk of the hard disk is, which is not limited herein.
