ESTPAIR with MODE(RESYNC) example
Deleting pairs with CDELPAIR, DELPAIR
Delete pairs using the CDELPAIR and PPRCOPY DELPAIR commands.
• The commands are issued to the S-VOL.
• If the pair is split, the T-VOL can be accessed by the host.
• If the pair is in any other status than split, non-reserved T-VOLs can be accessed by the host.
However, reserved simplex volumes cannot be accessed.
NOTE: When splitting duplex pairs, the S-VOL and its associated T-VOL(s) are usually not identical
since update copy operations are asynchronous. This means that the data integrity of the T-VOL
cannot be guaranteed. To insure data integrity of the T-VOL, split the pair before deleting.
Parameters and examples are provided in the following sections.
CDELPAIR
The following table describes the CDELPAIR command parameters used to delete pairs.
