Displaying pair information with CQUERY TSO, QUERY ICKDSF

You can view pair status and volume information using the CQUERY TSO and the QUERY ICKDSF
commands.
The commands can be issued to the S-VOL or T-VOL.
If an S-VOL has multiple T-VOLs, status displays for the pair whose T-VOL has the lowest LDEV
ID. To obtain status of a pair with another T-VOL, issue the command to the desired T-VOL.
If the system contains both Business Copy Z and Continuous Access Synchronous Z pairs, the
CQUERY and the PPRCOPY QUERY commands report Continuous Access Synchronous Z pair
status. To obtain the Business Copy Z status, issue the command to the Business Copy Z T-VOL.
When Business Copy Z and Continuous Access Synchronous Z share volumes, path status
displays for Continuous Access Synchronous Z. If they do not share volumes path status for
the Business Copy Z, the pair displays as FFFF FFFF.
The following sections provide the commands, parameters, and examples for displaying pair
information.
