PPRCOPY ESTPAIR parameters for resynchronizing pairs

DDNAME, SYSNAME, or UNITADDRESS

DDNAME = dname

SYSNAME = sysxxx

UNITADDRESS = ccuu

Only one of the three parameters can be specified. The italic term is the arbitrary name, where dname is the JCL statement that identifies the volume, sysxxx is the SYSNAME of the ASSGN system control statement, and ccuu is the device number.

PRI

Primary volume: SSID, serial number, channel connection address

You can specify the following additional parameters corresponding to each request instead of a serial number. If you do not specify an additional parameter, the request triggers a normal copy:

• For a Quick Resync, specify MRF00.

  This parameter is valid for MODE(RESYNC) only.

• For a Quick Restore, specify MRQ00.

  This parameter is valid for MODE(RESYNC) only.

• For a Reverse Copy, specify MRR00.

  This parameter is valid for MODE(RESYNC) only.

• To resync all pairs in a CTG, specify MAnn0, where nn is a CTG ID.

  You can execute resync by specifying this parameter.

You must use these parameters to successfully run the command.

Note: If you specify NO for the ONLINSEC parameter, and then request a Quick Restore or Reverse Copy operation, the command ends abnormally (reporting CC = 12).

SEC

Secondary volume: SSID, serial number, channel connection address

NA

MODE

RESYNC

Resynchronize a pair in the SUSPOP or SUSPER status.

PACE

1-255

Copy speed is medium, regardless what is specified for the PACE parameter.

CRIT

Not applicable

Not used by SIz.

MSGREQ

YES

To prevent the command from ending abnormally (reporting CC = 12), do not specify the parameter if MODE(RESYNC) is set.

NO

LSS

P-VOL or S-VOL CU number

NA

ONLINSEC*

YES

You can Normal Copy when the S-VOL is online or offline.

You can reverse resynchronize the pair when the P-VOL and S-VOL are online or offline.

NO

You can Normal Copy when the S-VOL is online.

You can reverse resynchronize the pair when the P-VOL and S-VOL are online. The ICKDSF job ends abnormally (reporting CC = 12).

Note: Although an error does not occur if you specify YES for this parameter, the copy operation is performed. The storage system does not check to see if the volume is online.

* Not specifying and specifying NO for this parameter has the same effect.
