Appeal No. 1997-3851
Application No. 08/355,210
The present invention relates to an array disk subsystem
having a plurality of secondary storage controllers and a
plurality of secondary storages wherein the subsystem is
capable of achieving ordinary input/output processing even
while a backup processor is being executed.
The independent claim 27 is reproduced as follows:
27. An array disk subsystem, comprising:
a) an ECC generator for producing an ECC for a plurality
of data;
b) a plurality of data disks for storing said plurality
of data and said ECC; and
(c) a write data storage means for, when a write
instruction is issued to one of said data disks while said
data disks execute an operation which prevents said data disks
from inputting and outputting data, temporarily storing data
to be written in said one of said data disks.
The Examiner relies on the following references:
Dishon et al. (Dishon) 4,849,978 Jul. 18, 1989
Satoh et al. (Satoh) 5,313,612 May 17, 1994
(effective filing date Aug. 31, 1989)
Claims 27 and 28 stand rejected under 35 U.S.C. § 103 as
being unpatentable over Dishon in view of Satoh.
