REUSE OF PROBLEMATIC DISKS IN A REDUNDANT DISK SYSTEM
First Claim
1. A method for reuse of a problematic disk in a Redundant Array of Independent Disks (RAID) system, the method comprising:
- performing formatting, initializing and validating operations on a first disk in the RAID system in response to the first disk experiencing a problem and determining that the first disk has not experienced a hard error; and
setting the first disk as a second-level redundant disk in the RAID system in order for the RAID system to use the first disk again in response to success of the validating operation on the first disk.

Abstract
The present disclosure discloses a method and system for reuse of a problematic disk in a Redundant Array of Independent Disks (RAID) system. The method includes performing formatting, initializing and validating operations on a first disk in the RAID system in response to the first disk experiencing a problem and determining that is not a hard error. The method may also include setting the first disk as a second-level redundant disk in the RAID system in order for the RAID system to use the first disk again in response to success of the validating operation on the first disk. The method and the system can enable the problematic disks isolated out of the system due to media errors and/or slow disk errors in the high-end RAID storage to be reused by the RAID system under the precondition of ensuring the reliability of the system.

11. A system for reuse of a problematic disk in a Redundant Array of Independent Disks (RAID) system, the system comprising:
-
a problematic disk initial processing apparatus configured to perform formatting, initializing and validating operations on a first disk in the RAID system in response to the first disk experiencing a problem and subsequently determining that the first disk has not experienced a hard error; and a problematic disk setting apparatus configured to set the first disk as a second-level redundant disk in the RAID system in order for the RAID system to use the first disk again in response to success of the validating operation on the first disk. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
