System and method for managing replication sets of data distributed over one or more computer systems

A computer system for managing data that may be replicated from one or more volumes of data, the computer system comprising:

• a data storage system including a plurality of storage devices;
• first and second computer systems in communication with the data storage system, the first computer system having a first operating system and the second computer system having a second operating system, wherein the first computer system has data that may be replicated from one or more volumes of data that are part of a first volume group on the first computer system;
• and
• a backup storage system in operable communication with the data storage system and the first and second computer systems, the backup storage system comprising computer-executable logic that enables the method steps of:
• discovering logical information related to the one or more volumes of data that are part of the first volume group on the first computer system;
• creating a map of the logical information to physical devices on the first computer system the map defining a first logical configuration comprising:
• information identifying the devices associated with one or more physical volumes containing the data, including device serial number, physical address of the device, volume group, logical volume name, file type, and mount point;
• and,
• information providing definition and structured layout of the first volume group, first internal logical volumes and first file systems on the first computer system;
• using the map to create a second volume group on a second computer system, where the logical configuration of the second volume group is identical to the first logical configuration of the first volume group, including identical volume layout and file system structure as defined by mapping information originally built on the first computer system;
• and
• using the map to reconstruct on the second computer system the internal logical volumes and file systems of the first computer system;
• and
• mounting a duplicate of the one or more volumes of data of the first computer system to the second volume group of the second computer system having a second operating system.

A program product for use with a data storage system having a plurality of storage devices and which is in communication with first and second computer systems, the program product being for management of data and being comprised of:

• computer-executable logic contained on a computer-readable storage medium and which is configured for causing the following computer-executed steps to occur:
• establishing one or more mirrored copies of data that are copies of one or more volumes of data that are part of a first volume group on a first computer system having a first operating system;
• separating the one or more mirrored copies of data from the respective one more volumes of data;
• discovering logical information related to the one or more volumes of data that are part of the volume group on the first computer system;
• creating a map of the logical information to physical devices on the first computer system, the map defining a first logical configuration comprising:
• information identifying the devices associated with one or more physical volumes containing the data, including device serial number, physical address of the device, volume group, logical volume name, file type, and mount point;
• and
• information providing definition and structured layout of first volume group, first internal logical volumes and first file systems on the first computer system;
• using the map to create a second volume group on a second computer system, where the second logical configuration of the second volume group is identical to the first logical configuration of the first volume group, including identical volume layout and file system structure as defined by mapping information originally built on the first computer system;
• using the map to reconstruct on the second computer system the internal logical volumes and file systems of the first computer system;
• and
• mounting a duplicate of the one or more mirrored copies of data of the first computer system to the second volume group of the second computer system.
