Description: Before z/OS V1R13, a patch was required to enable (and subsequently disable) ARC1809I messages during fast replication volume pairing. Starting with z/OS V1R13, the VOLUMEPAIRMESSAGES parameter is added to the existing SETSYS FASTREPLICATION command to control the issuance of the ARC1809I messages. Remove the patch and replace it with the new parameter.
