  • Method for providing deferred maintenance on storage subsystems
    Patent number: 8020032
    Abstract: A set of disks in a plurality of disk arrays are configured to have one or more spare partitions. Upon detecting a faulty disk in a faulty array, the method involves the steps of: (a) migrating data in the faulty array containing the faulty disk to one or more spare partitions; (b) reconfiguring the faulty array to form a new array without the faulty disk; (c) migrating data from one or more spare partitions in the set of disks to the reconfigured new array; (d) monitoring to identify when overall spare capacity falls below a predetermined threshold; and when the predetermined threshold is exceeded, scheduling a service visit for replacement of the failed disks.
