Appeal No. 2003-1473
Application No. 09/336,649
computer systems interface (SCSI) bus by automatically altering
the IDs of each target device on a cross-linked bus. Since
different devices on each section of the bus must be uniquely
recognized, it is necessary to avoid SCSI ID numbers that are
duplicates of numbers in another section of the bus
(specification, page 3).
Representative independent claim 1 is reproduced below:
1. A method for selectively interconnecting two SCSI host
buses where each SCSI host bus includes a host device and a
plurality of addressable SCSI devices each having a SCSI ID, said
method comprising the steps of:
interposing a repeater between a first SCSI host bus and a
second SCSI host bus;
selectively enabling the repeater; and
automatically altering the SCSI ID of each SCSI device on
the second SCSI host bus in response to the enabling of the
repeater such that there are no overlapping SCSI IDs within the
two combined SCSI host buses.
The Examiner relies on the following references in rejecting
the claims:
Pascarella et al. (Pascarella) 6,055,582 Apr. 25, 2000
(filed Jan. 16, 1998)
IBM Technical Disclosure Bulletin (IBM TDB), “SCSI Switches for
Redundant Arrays,” vol. 34, no. 6, Nov. 1991, pp. 342-343.
Claims 1-8 stand rejected under 35 U.S.C. § 103(a) as being
unpatentable over IBM TDB in view of Pascarella.
