Abstract
A storage controller receives a write command with respect to a track, from a host. A first process determines that the track is a source track and also determines that at least one corresponding target track is in an incremental copy relation to the source track. A second process is generated to modify a target change recording structure, where the second process executes in parallel with the first process.
Claims20
A method, comprising:
- receiving, by a processor, a write command with respect to a track, from a host;
- determining, via a first process, that the track is a source track and also determining at least one corresponding target track is in an incremental copy relation to the source track;
- and
- generating, a second process to modify a target change recording structure, wherein the second process executes in parallel with the first process.

A system, comprising:
- a memory;
- and
- a processor coupled to the memory, wherein the processor performs operations, the operations comprising:
- receiving a write command with respect to a track, from a host;
- determining, via a first process, that the track is a source track and also determining at least one corresponding target track is in an incremental copy relation to the source track;
- and
- generating, a second process to modify a target change recording structure, wherein the second process executes in parallel with the first process.

A computer program product, the computer program product comprising:
- a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform operations on a processor, the operations comprising:
- receiving a write command with respect to a track, from a host;
- determining, via a first process, that the track is a source track and also determining at least one corresponding target track is in an incremental copy relation to the source track;
- and
- generating, a second process to modify a target change recording structure, wherein the second process executes in parallel with the first process.
