摘要:
A system and method of controlling copying including a management table for managing an update target data in a first storage volume and stored locations of before-update data of the update target data in a second storage volume, and relocating data in the second storage volume upon confirming a predetermined range of the first storage volume has been copied into the second storage volume using the management table.

摘要:
An apparatus having a monitoring means which monitors the number of input/output requests waiting for reconnection, and a switching means which dynamically switches a reconnection request issuing system to be executed by a controlling means to either a first system (one path mode) or a second system (scattering mode), thereby rapidly solving the waiting state when the number of the input/output requests waiting for reconnection is large, while preventing the busy rate of paths from unnecessarily increasing.
