MSGREQ function is not applicable. NO
You can Normal Copy when the S-VOL is online
and offline. YES ONLINSEC*
You can reverse resynchronize the pair when the
P-VOL and S-VOL are online and offline.
You cannot Normal Copy when the S-VOL is online. NO
If the P-VOL and S-VOL are online, you cannot
reverse resynchronize the pair.
* Not specifying and specifying NO for this parameter has the same effect.
The following image shows an example of running the CESTPAIR PPRC command with
MODE(RESYNC):
PPRCOPY ESTPAIR parameters and examples
The following table describes the PPRCOPY ESTPAIR PPRCOPY command parameters used to
resynchronize pairs.
Description Value Parameters
Only one of the three parameters should be
specified. The italic term is the arbitrary name. DDNAME = dname = JCL statement identifying
the volume. DDNAME,
SYSNAME, or
UNITADDRESS
For example, dname is the arbitrary unique
SYSNAME = sysxxx = SYSNAME in the ASSGN
system control statement.
name of the JCL statement which identifies the
volume.
UNITADDRESS = ccuu = device number.
You must use these parameters to successfully
run the command. Primary volume: SSID, serial number, channel
connection address. PRI
Caution: To prevent the job from ending
abnormally (reporting CC = 12), if you need You can set an additional parameter
corresponding to each request instead of a serial
to reverse resynchronize, specify YES for the
ONLINSEC parameter. number. If you do not set an additional
parameter, the request triggers a normal copy.
Note: The copy operation is performed whether
the volume is online or not. For a Quick Resync, set MRF00. This parameter
is valid for MODE(RESYNC) only.
For a Quick Restore, set MRQ00. This parameter
is valid for MODE(RESYNC) only.
For a Reverse Copy set MRR00. This parameter
is valid for MODE(RESYNC) only.
To resync all pairs in a CG, set MAnn0 instead
of a serial number. The request triggers a Normal
Resync.
Note: nn is a CTG ID.
NA Secondary volume: SSID, serial number, channel
connection address. SEC
