If the feature codes indicate that multi-target PPRC is supported, and the function is enabled through the DEVSUPxx member of PARMLIB, the PPRCOPY QUERY command is performed with the appropriate scope, requesting that results be returned with, potentially, multiple relationships. The output is added to the existing Query Remote Copy Volume table, representing a message block for each relationship, for example:
ICK00700I DEVICE INFORMATION FOR 3109 IS CURRENTLY AS FOLLOWS:
PHYSICAL DEVICE = 3390
STORAGE CONTROLLER = 2107
STORAGE CONTROL DESCRIPTOR = E8
DEVICE DESCRIPTOR = 0A
ADDITIONAL DEVICE INFORMATION = 4A00243D
TRKS/CYL = 15, # PRIMARY CYLS = 1113
ICK04030I DEVICE IS A PEER TO PEER REMOTE COPY VOLUME

00016 03 02412 01The values for the PM column indicate whether the pair is to be used for a Preserve Mirror function in a multi-target PPRC configuration. A value of N/A means the device is in simplex state or the device does not support multi-target PPRC.
For the PPRCOPY QUERY PATHS command, up to 16 secondary control units can be defined to each primary control unit, and each can each have up to 8 FCP paths defined, for example:
PATHS:
SERIAL WORLD WIDE
NUMBER SSID LSS NODE NAME PATH SAID DEST S*
