Initial copy for remote copy
First Claim
1. A method of performing an initial copy procedure in a remote copy system, the method comprising:
- configuring a network path between a first disk subsystem and a second disk subsystem to increase the speed of data transmission across the network path;
configuring the remote copy system for a remote copy operation;
performing an initial copy operation to copy data across the network path from the first disk subsystem to the second disk subsystem; and
adjusting the network path to reduce the speed of data transmission across the network path.

Abstract
A method of performing an initial copy procedure in a remote copy system, the method including: configuring a network path between a first disk subsystem and a second disk subsystem to increase the speed of data transmission across the network path; configuring the remote copy system for a remote copy operation; performing an initial copy operation to copy data across the network path from the first disk subsystem to the second disk subsystem; and adjusting the network path to reduce the speed of data transmission across the network path. A remote copy system, including: a first disk subsystem located at a first site; and a second disk subsystem capable to be coupled to the first disk subsystem via a network path, with the network path capable to be configured to increase or decrease the speed of data transmission from the first disk subsystem to the second disk subsystem.
