Deleting Pairs: CDELPAIR and PPRCOPY DELPAIR

The CDELPAIR and PPRCOPY DELPAIR commands are equivalent to the Siz delete pair operation (changes

pair status to simplex). 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!

For duplex Siz pairs, the S-VOL and its associated T-VOL(s) are usually not identical; 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.

The following is an example of the CDELPAIR command.

CDELPAIR

DEVN (X ‘DE80’ )

PRIM (X ‘0080’ ,30158,X ‘00’ ) SEC (X ‘0080’ ,30158,X ‘01’ )

The following is an example of the PPRCOPY DELPAIR command.
