Abstract
Official abstract text for this publication.
For synchronizing replication status, a copy module continuously replicates data from a first device designated with a device status of primary to a second device designated with a device status of secondary. A first peer-to-peer remote copy (PPRC) relationship is established between the first and second devices. The first and second devices store replication information comprising a bitmap with a replication status for each data block of the first device. The copy module further copies an instant point-in-time copy of the data from the second device to a copy device. In addition, the copy module copies the replication information from the second device to the copy device and links the replication information of the second device and copy devices.
First claim
