초록 ▼

A disk array data storage system has plural sets of storage disks connected to multiple corresponding I/O buses. Individual storage disks can be independently and asynchronously attached to or detached from corresponding interfacing slots of the I/O buses. The system has physical device drivers which represent the storage disks with respect to their connections to the interfacing slots of the I/O buses and physical device managers which represent the data kept on the storage disks. Interface drivers are provided to manage I/O transfers through corresponding I/O buses. When a particular storage disk is attached to or detached from an interfacing slot of an I/O bus, the interface driver corresponding to the I/O bus freezes all I/O requests that come from the physical device drivers that represent the storage disks in the set connected to the I/O bus. A configuration manager determines which interfacing slot the particular storage disk has been attached to or detached from. If the particular storage disk has been detached from the I/O bus, the configuration manager eliminates the physical device driver that represents the detached storage disk. The data stored on the detached storage disk is rebuilt using redundancy on the remaining disks. If the particular storage disk has been attached to the I/O bus, the configuration manager creates a new physical device driver to represent the attached storage disk. The I/O requests to the I/O bus are then unfrozen.

A disk array data storage system comprising: a plurality of storage disks; multiple I/O buses, individual ones of the internal I/O buses being connected to a set of storage disks; the storage disks being detachably connected to the I/O buses at interfacing slots whereby individual storage disks can be asynchronously attached to or detached from corresponding interfacing slots of the I/O buses; a plurality of physical device drivers for corresponding storage disks, the physical device drivers representing the storage disks with respect to their connections to the interfacing slots of the I/O buses; a plurality of physical device managers for corresponding storage disks, the physical device managers representing data kept on the storage disks, the physical device managers being associated with corresponding physical device drivers that represent the same storage disks; interface drivers to manage I/O transfers through corresponding I/O buses; when a particular storage disk is attached to or detached from an interfacing slot of one of the I/O buses, the interface driver corresponding to said one I/O bus freezing I/O requests that came from the physical device drivers that represent the storage disks in the set connected to said one I/O bus; a configuration manager to manage operation of the disk array data storage system when said particular storage disk is attached to or detached from said one I/O bus, the configuration manager first determining which interfacing slot the particular storage disk has been attached to or detached from and then subsequently instructing the interface driver to unfreeze the I/O requests and flush the I/O requests back to the physical device drivers associated with the other storage disks in the set of storage disks connected to said one I/O bus.
