Deleting Pairs Using PPRC Commands

The CDELPAIR and PPRCOPY DELPAIR commands are equivalent to the ShadowImage for Mainframe
delete pair operation. The CDELPAIR and PPRCOPY DELPAIR commands must be issued to the
S-VOL.
A DELPAIR command performed when pair status is split enables the T-VOL to be accessed by the
host. A DELPAIR command performed when pair status is other than split allows non-reserved
T-VOLs to be accessed by the host. Reserved simplex volumes cannot be accessed.
WARNING!
because SIz update copy operations are asynchronous. Therefore, if a pair is deleted with status
other than split, the data integrity of the T-VOL cannot be guaranteed.

For duplex SIz pairs, the S-VOL and its associated T-VOLs are usually not identical,

Value Description
Pair resynchronize operation (forward) will be
performed whether the T-VOL is online or not.
Pair resynchronize operation (backward) will
be performed whether the S-VOL and T-VOL
are online or not.
Pair resynchronize operation (forward) will not
be performed if the T-VOL is online .
Pair resynchronize operation (backward) will
not be performed when the status of the
volumes are online or offline. The ICKDSF job
ends abnormally (CC = 12).
Although no error occurs when you specify
YES for this parameter, note that the copying
operation is performed without any online
check.
