Abstract
The invention relates to a disk drive controller system having redundant operations spread between at least two SCSI adaptors connected to a SCSI bus. At least one host computer is also connected to the SCSI bus. If one of the SCSI adaptors fails, the other SCSI adaptor connected to the bus, upon detecting the failure, takes over for the devices serviced by the failing SCSI adaptor. A special termination connection, in which one SCSI adaptor terminates the SCSI bus while the other SCSI adaptor does not, is provided for implementing the invention. A defined process enables the detecting SCSI adaptor to take over for the failed SCSI adaptor and for the failed SCSI adaptor to thereafter return to normal operation.
