CAUTION: The QUIESCE option of the CSUSPEND command has been disabled by APAR
OW15247 or APAR OW15248. See either of these APARs and the latest IBM PPRC documentation
for detailed information on the QUIESCE option of the CSUSPEND command. Please check with
your HP account team before using the CSUSPEND command with the QUIESCE option to suspend
Continuous Access Synchronous Z pairs on P9500 storage systems. If the CSUSPEND command
with the QUIESCE option is issued to certain volumes (for example, active SPOOL, PAGE, or
CATALOG datasets, active SYSRES volume), the attached host(s) may enter a deadlock condition
and may require a storage control IML to correct the condition.
For Fibre Channel interface, do not use the CESTPATH and CDELPATH commands at the same
time as the SCSI path definition function of LUN Manager. The FC ports need to be configured

Description
Access Synchronous Z supports the optional
FORMAT/UNFORMAT and VOLUME/PATHS
parameters.
Establishes a Continuous Access Synchronous
Z pair and sets the initial copy and pair options
(copy mode = synchronous only, priority = 0,
CFW data = copy to R-VOL, DFW to R-VOL =
not required). Continuous Access Synchronous
Z supports the optional MODE, PACE, and
CRIT parameters. The MSGREQ parameter
defaults to NO.
Suspends a Continuous Access Synchronous
Z pair. Continuous Access Synchronous Z
supports the optional PRIMARY parameter. See
WARNING about the QUIESCE parameter at
the end of this section.
Releases a Continuous Access Synchronous Z
pair from the MCU.
Releases a Continuous Access Synchronous Z
pair from the RCU.
Displays the Continuous Access Synchronous
Z pair status of the volume. Continuous Access
Synchronous Z supports the optional
FORMAT/UNFORMAT and VOLUME/PATHS
parameters.
Resynchronizes a Continuous Access
Synchronous Z pair, and sets the Continuous
Access Synchronous Z initial copy options and
pair options. Continuous Access Synchronous
Z supports the optional MODE, PACE, and
CRIT parameters.
Supported by Continuous Access Synchronous
Z. Redirects application I/Os from the M-VOL
to the R-VOL.
Supported by Continuous Access Synchronous
Z.
