CQUERY COMMAND COMPLETED FOR DEVICE 2D00. COMPLETION CODE: 00
Note that the CQUERY commands and their output are also written to SYSLOG. This may
flood the SYSLOG when you issue many CQUERY commands. An alternative may be to
query the Global Copy volume pairs and their status with ICKDSF-based query commands.
26.3.3 Establish FlashCopy relationships
Once the first pass is completed for Global Copy, establish the FlashCopy relationships
between the B and C volumes. Example 26-11 shows three FCESTABL TSO commands to
establish the FlashCopy pairs: one FlashCopy pair in the first LSS pair, and two FlashCopy
pairs in the second LSS pair. Note that this example implies that there is a host connectivity to
the remote storage disk subsystem, because the FlashCopy commands are directed to the
source and target FlashCopy volumes via their z/OS device numbers. No inband FlashCopy
TSO commands are used here.
