A-36 Using PPRC Commands for TrueCopy for z/OS
Hitachi Universal Storage Platform V TrueCopy for IBM z/OS User’s Guide
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 resynchronize the TCz 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 release the TCz pairs suspended by the
CGROUP/RUN command. If CDELPAIR is issued to a TCz pair whose MCU-RCU
path is still blocked, the MCU rejects the command (F/M=0F, TCz 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. Figure A.5 shows the output of the CQUERY command
issued to a TCz MCU to which the CGROUP/FREEZE command has been issued.
Figure A.6 shows the output of the CQUERY command issued to the TCz RCU
which has a blocked path due to the CGROUP/FREEZE command.
CQUERY/VOLUME. Figure A.7 shows the output of the CQUERY command
issued to a TCz M-VOL which has been suspended by the CGROUP/RUN
command. As shown in Figure A.7, CQUERY issued to an M-VOL also indicates
the status of the FREEZE option: CGRPLB(YES) = enabled, CGRPLB(NO) =
disabled. Figure A.8 shows the output of the CQUERY command issued to a
TCz R-VOL whose M-VOL has been suspended by the CGROUP/RUN command.
The pair status and path status at the RCU are not changed.
