148 TrueCopy for the XP128/XP1024/XP10000/XP12000
CAUTION: The QUIESCE option of the CSUSPEND command has been disabled by APAR OW15247 or
APAR OW15248. For detailed information on the QUIESCE option of the CSUSPEND command, refer to
either of these APARs. Check with your HP account team before using the CSUSPEND command with the
QUIESCE option to suspend TC390 volume pairs on an XP128/XP1024/XP10000/XP12000 (or other XP
disk array). If the CSUSPEND command with the QUIESCE option is issued to certain volumes (for
example, active SPOOL, PAGE, or CATALOG datasets, or active SYSRES volume), the attached host(s) may
enter a deadlock condition and may require a storage control IML to correct the condition. TC390A does
not support the CSUSPEND/QUIESCE option.
Using PPRC TSO Commands with TrueCopy Asynchronous
For TC390A operations, special switches and parameters are used to control and monitor TC390A pairs
and groups using PPRC commands. This section describes this special use of PPRC TSO commands for
Suspend Pair CSUSPEND PPRCOPY
SUSPEND
M-VOL or
R-VOL
Suspends a TC390 pair (or TC390A group).
TC390 supports the optional PRIMARY
parameter. See Caution below on the
QUIESCE parameter. For details on
CSUSPEND for TC390A, see ” CSUSPEND”
on page 154 .
Delete Pair
(to MCU)
CDELPAIR PPRCOPY
DELPAIR
M-VOL Deletes a TC390 pair (or TC390A group)
from the MCU. For details on using CDELPAIR
for TC390A, see ” CDELPAIR” on page 155 .
Delete Pair
(to RCU)
CRECOVER PPRCOPY
RECOVER
R-VOL Deletes a TC390 pair (or TC390A group)
from the RCU. For details on using
CRECOVER for TC390A, see ” CRECOVER”
on page 155 .
Pair Status CQUERY/
VOLUME
PPRCOPY
QUERY/
VOLUME
M-VOL or
R-VOL
Displays the TC390 and TC390A pair status
of the volume. TC390 supports the optional
FORMAT/UNFORMAT and VOLUME/PATHS
parameters. For details on using CQUERY for
TC390A, see ” CQUERY for Serial Interface”
on page 156 .
Resume Pair CESTPAIR
(MODE=
RESYNC)
PPRCOPY
ESTPAIR
M-VOL Resumes a TC390 pair (or TC390A group),
and sets the TC390 initial copy options and
pair options. TC390 supports the optional
MODE, PACE, and CRIT parameters. For
details on using CESTPAIR/RESYNC for
TC390A, see ” CESTPAIR ” on page 152.
----- P/DAS
SWAP
----- M-VOL and
R-VOL
Supported by TC390 Synchronous.
Command is rejected by TC390A pairs.
Redirects application I/Os from the M-VOL to
the R-VOL. For details on using P/DAS SWAP
with TC390, see ” P/DAS Support ” on
page 43.
----- CGROUP
(FREEZE/
RUN)
----- MCU (M-VOL
or simplex)
Supported by TC390 Synchronous.
Command is rejected by TC390A pairs. For
details on using CGROUP (FREEZE/RUN)
with TC390 Synchronous pairs, see
” CGROUP (FREEZE/RUN) Support” on
page 158 .
