CESTPAIR parameters for resynchronizing pairs

DEVN

Device number

NA

PRIM

Primary volume: SSID, serial number, channel connection address, and CU number

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.

SEC

Secondary volume: SSID, serial number, channel connection address, and CU number

NA

MODE

RESYNC

Resynchronize a pair in the SUSPOP or SUSPER status. This parameter is required.

PACE

Any number

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

CRIT

Not applicable

Not used by SIz.

MSGREQ

YES

MSGREQ function is applicable.

Note: Do not specify YES for this parameter when you request resync on all pairs in a CTG. If you specify YES for this parameter, the command ends abnormally (reporting CC = 8).

NO

MSGREQ function is not applicable.

ONLINSEC*

YES

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

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

NO

You cannot Normal Copy when the S-VOL is online.

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.
