Abstract: A system and method for monitoring a group of storage devices for indications of a detected error. After receiving an indication that a first storage device in the group has experienced a detected error, a consecutive number of detected errors experienced by the first storage device is determined. If it is determined the consecutive number of detected errors experienced by the first storage device exceeds a threshold of more than one detected error before a second storage device in the group experiences one detected error, then in response, the consecutive number of detected errors experienced by the first storage device is reset. If the consecutive number of detected errors does exceed the threshold before the second storage device experiences the one detected error, then the first storage device is identified as a suspect storage device.

Abstract: A group of disks is monitored for indications of a detected error. After receiving an indication that a first disk in the group has had a detected error, determining a consecutive number of detected errors for the first disk. Determining if the consecutive number of detected errors exceeds a threshold, and if the consecutive number of detected errors does exceed the threshold, identifying the first disk as a suspect disk. In response to determining that the first disk had the most recent detected error, incrementing the number of consecutive errors of the first disk by one. If a disk other than the first disk had a most recent detected error, setting the consecutive number of detected errors of the disk other than the first disk to one, and setting the consecutive number of detected errors of the first disk to zero.
