ABSTRACT:
A method for controlling and emulating the functional and logical behaviors of an array of storage devices is established by loading a software module to an array controller board. The software module is integrated into the array controller subsystem manager by providing the necessary parameters required to insert the device and can control the inbound and outbound activities (commands, data, and status packages) regardless of the type, interface, and protocol of the disk/tape device. This aspect of the method allows the user to control the drive state transition and inject errors on the inbound and outbound drive traffics. Also, the method of this invention allows the drive module to recover in case of an array controller failure and to be removed from a list of devices like a regular drive.
