Abstract

Official abstract text for this publication.

A mechanism is provided for adding point-in-time copy relationships to a data processing system. A request is received to establish a first point-in-time copy relationship. Responsive to determining that a first target of the first point-in-time copy relationship is target write inhibited, that a source of the first point-in-time copy relationship is a source of a first continuous synchronous copy relationship, that a target of the first continuous synchronous copy relationship is part of a second point-in-time copy relationship, and that the source of the first point-in-time copy relationship is part of a volume swap configuration, a volume swap relationship is added between the first point-in-time target volume and the second point-in-time target volume to the volume swap configuration. Both point-in-time copy relationships are established and any continuous synchronous copy requirements of the volume swap relationship between the first point-in-time target volume and the second point-in-time target volume are disabled.

First claim

Opening claim text (preview).

What is claimed is: 1. A method, in a data processing system, for adding point-in-time copy relationships to the data processing system, the method comprising: establishing a volume swap relationship between a first point-in-time target volume and a second point-in-time target volume, wherein the first point-in-time target volume is a candidate for a non-continuous synchronous copy volume swap relationship by: establishing a first point-in-time copy relationship for the first poi…
