Abstract:
1. A computer implemented method for processing data blocks within a disk group, the method comprising: identifying components within an application server environment, the components comprising at least one mirror site; receiving, at a server, a trigger event from at least one of the components, the trigger event indicating at least one suspect corrupted block using a block identifier; determining existence of a single mirror site in the disk group, wherein the single mirror site contains data at a location corresponding to the block identifier; classifying the trigger event into at least one of a plurality of trigger event types; retrieving, from the single mirror site, a first stored data block corresponding to the block identifier; comparing the first stored data block to the at least one suspect corrupted block to determine a match value; and invoking a check disk operation when the match value is greater than a confidence threshold.
