1. A method of passing host requests to a disk array while reconfiguring the disk array, the disk array having a source logical volume and a destination logical volume, pre-reconfiguration data being associated with the source logical volume and post-reconfiguration data being associated with the destination logical volume, comprising the steps of: detecting if a host request to the drive array corresponds to post-reconfiguration data or pre-reconfiguration data; issuing the host request to the source logical volume if the host request corresponds to the pre-reconfiguration data; and issuing the host request to the destination logical volume if the host request corresponds to post-reconfiguration data.
