Method, electronic device, and program product for failure handling

An electronic device, comprising:

• at least one processing unit;
• and
• at least one memory coupled to the at least one processing unit and storing instructions for execution by the at least one processing unit, wherein the instructions, when executed by the at least one processing unit, cause the device to perform actions comprising:
• determining a sector set failure type associated with at least one failed sector set of a disk, wherein the sector set failure type is associated with at least one failed sector set to which at least one failed sector of the disk belongs at a predetermined time point after a first time period, and wherein the determining the sector set failure type comprises:
• acquiring a plurality of disk failure data sets associated with the at least one failed sector that are collected in the first time period;
• and
• determining the sector set failure type based on a trained failure determining model and the plurality of disk failure data sets;
• in response to determining the sector set failure type indicates that a number of failed sector sets in the at least one failed sector set is greater than a first threshold number, generating an instruction for replacing the disk;
• and
• in response to determining the sector set failure type indicates that the number of failed sector sets in the at least one failed sector set is less than or equal to the first threshold number, performing at least one of:
• in response to determining a number of failed sectors is greater than a second threshold number and less than or equal to the first threshold number in a failed sector set in the at least one failed sector set, migrating data from the failed sector set, in the at least one failed sector set, in which the number of failed sectors is greater than the second threshold number and less than or equal to the first threshold number, to a spare sector set, wherein the second threshold number is less than the first threshold number, or
• performing a failure recovery for a failed sector set, in the at least one failed sector set, in which the number of failed sectors is less than or equal to the second threshold number.

A non-transitory computer-readable medium having machine-executable instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:

• determining a sector set failure type associated with at least one failed sector set of a disk, wherein the sector set failure type is associated with at least one failed sector set to which at least one failed sector of the disk belongs at a predetermined time point after a first time period, and wherein the determining the sector set failure type comprises:
• acquiring a plurality of disk failure data sets associated with the at least one failed sector that are collected in the first time period;
• and
• determining the sector set failure type based on a trained failure determining model and the plurality of disk failure data sets;
• in response to determining the sector set failure type indicates that a number of failed sector sets in the at least one failed sector set is greater than a first threshold number, generating an instruction for replacing the disk;
• and
• in response to determining the sector set failure type indicates that the number of failed sector sets in the at least one failed sector set is less than or equal to the first threshold number, performing at least one of:
• in response to determining a number of failed sectors is greater than a second threshold number and less than or equal to the first threshold number in a failed sector set in the at least one failed sector set, migrating data from the failed sector set, in the at least one failed sector set, in which the number of failed sectors is greater than the second threshold number and less than or equal to the first threshold number, to a spare sector set, wherein the second threshold number is less than the first threshold number, or
• performing a failure recovery for a failed sector set, in the at least one failed sector set, in which the number of failed sectors is less than or equal to the second threshold number.
