ABSTRACT:
The present invention provides a storage control subsystem that facilitates logical volume access management by a host. Before copying, the host instructs a disk array device to identify the states of target logical volumes and collect information in control memory, whereupon the disk array device reads information in the control memory and reports information relating to the target logical volumes to the host.
