ABSTRACT:
An adapter connected between a host computer and disk storage devices provides interfaces for connecting to the host computer and the disk storage devices having the same interface design. The adapter itself includes control means for building a redundant disk storage system. Moreover, the adapter itself includes means for detecting and indicating a failed disk storage device, means for replacing the failed disk storage device, and means for rebuilding a redundant disk storage system after the replacement of disk storage devices. A command is configured so that the host computer can have access to each of disk storage devices for maintenance purposes. The adapter makes it easy to configure a highly reliable redundant disk storage system for a small computer system without any change to existing hardware or software.
