When OPENDVCS(YES) and REMOTE(YES) are both specified, DEVN identifies a CKD access volume located in the same subsystem cluster as the PPRC primary paired with the PPRC secondary acting as the FlashCopy source.
When REMOTE(YES) is specified for CKD volumes ((OPENDVCS(NO) is specified or allowed to default), DEVN identifies the PPRC primary device paired with the PPRC secondary acting as FlashCopy source.
DEVN must be a 4-digit hexadecimal address of a configured device with a UCB on the System z® system issuing the command.
