for Mainframe The IBM-compatible PPRC FC path interface has
been supported with RAID500 50-06-11-00/00. As
the specification of QUERY display using this
interface (hereinafter called New Spec) is different
from the current specification (hereinafter called
Previous Spec), this mode enables to display the
PPRC path QUERY with the New Spec or Previous
Spec.
Mode 484 = ON :
PPRC path QUERY is displayed with the New Spec.
Mode 484 = OFF (default):
PPRC path QUERY is displayed with the Previous
Spec
(ESCON interface).
Note:
(1) Set this mode to ON when you want to maintain
compatibility with the Previous Spec for PPRC path
QUERY display under the environment where IBM
host function (such as PPRC and GDPS) is used.
(2) When an old model or a RAID500 that doesn’t
support this mode is connected using TCz, set this
mode to OFF.
(3) If the display specification is different between
MCU and RCU, it may cause malfunction of host.
(4) When TPC-R is used, which is IBM software for
disaster recovery, set this mode to ON.
