Table 22 PPRCOPY ESTPAIR parameters (resynchronizing pairs)
Parameters Value
DDNAME, DDNAME = dname = JCL statement identifying
SYSNAME, or the volume.
UNITADDRESS
SYSNAME = sysxxx = SYSNAME in the ASSGN
system control statement.
UNITADDRESS = ccuu = device number.
PRI Primary volume (S-VOL): SSID, serial number,
channel connection address.
You can set an additional parameter
corresponding to each request instead of a serial
number. If you do not set an additional
parameter, the request triggers a normal copy.
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 consistency group. set
MAnn0 instead of a serial number. nn is a CTG
ID. The request triggers a normal resync
operation.
SEC Secondary volume (T-VOL): SSID, serial number,
channel connection address.
MODE RESYNC
PACE 1–255
CRIT Not applicable
MSGREQ YES
NO
LSS Primary or secondary volume CU number.
*1
ONLINSEC YES
NO
1
* When you do not specify the parameter, the result is same as when you specify NO for this parameter.
Description
Only one of the three parameters should be
specified. The italic term is the arbitrary name.
For example, dname is the arbitrary unique
name of the JCL statement which identifies the
volume.
These parameters must be used for successful
execution of the command.
Caution: When a Quick Restore or a Reverse
Copy operation is required and if you specify
NO for the ONLINSEC parameter, the job
ends abnormally by reporting CC = 12. If you
specify YES for the ONLINSEC, the job ends
normally. However, note that the copying
operation is performed without any online
check.
NA
Re-establish a split or suspended pair.
Copy speed is medium, regardless what is
specified for the PACE parameter.
Not used by Business Copy Z.
Do not specify this parameter when
MODE(RESYNC) is set, otherwise it ends
abnormally (CC = 12).
NA
Forward pair resynchronization can be
performed whether the T-VOL is online or not.
Backward pair resynchronization can be
performed whether the S-VOL and T-VOL are
online or not.
Forward pair resynchronization is not
performed when the T-VOL is online.
Backward pair resynchronization is not
performed when the S-VOL and T-VOL are
online. The ICKDSF job ends abnormally (CC
= 12).
Although no error occurs when you specify
YES for this parameter, that the copying
operation is performed without any online
check.
