replacement disk was provided. However, Jones and Ewert would
not meet the limitation of regenerating the data of the data
chunk located on the failed disk and writing the regenerated
data onto the parity chunk associated with the data chunk to
form a fully folded array, as the array would have already
existed upon failure of the parity disk. Similarly, Jones and
Ewert would not meet the limitation of claim 2 of reorganizing
the data chunks of the array to form an array characteristic
of a RAID level-0 array since the array would have already
existed upon failure of the parity disk. In addition, Jones
and Ewert would not meet the limitation of claim 3 determining
which one of said n active disks originally contained a chunk
of parity information because the parity information was on
the failed disk.
From our analysis, supra, we conclude that the examiner
has failed to establish a prima facie case of obviousness over
Jones
and Ewert. Accordingly, the rejection of claims 1-3 under 35
U.S.C. § 103 as obvious over Jones and Ewert is reversed.
