Using PPRC TSO Commands with CGROUP Support

CESTPATH. You can use the CESTPATH command to recover a blocked MCU-RCU path. Make sure to use

the same parameters as when the path was established.
CESTPAIR. After you re-establish the MCU-RCU path that was blocked, you can use the CESTPAIR/RESYNC

command to resume the TC390 pairs suspended by the CGROUP/RUN command.
CDELPAIR. After you re-establish the MCU-RCU path that was blocked, you can use the CDELPAIR

command to delete the TC390 pairs suspended by the CGROUP/RUN command. If CDELPAIR is issued to

a TC390 pair whose MCU-RCU path is still blocked, the MCU rejects the command (F/M=0F, TC390 error

code=5A).
CRECOVER. You can use the CRECOVER command to change a suspended R-VOL to simplex. This

command is issued to the R-VOL and does not affect the suspended M-VOL.
CQUERY/PATHS. The following example shows the output of the CQUERY command issued to a TC390

MCU to which the CGROUP/FREEZE command has been issued.
