Abstract:
The process of detecting a channel containing a faulty storage device or faulty circuitry connecting a channel with synchronization hardware in a multiple storage device system in which storage devices are arrayed in at least three channels, and each channel is served by a single buffer which serves only that channel and is located between the storage devices and synchronization hardware, and all channels are synchronized by the hardware and connected to the hardware comprising the steps:a. firstly, determining the byte count for each buffer,b. secondly, comparing the byte counts in each buffer,c. thirdly, determining the buffer whose byte count diverges most from the other buffer byte counts,d. finally, designating the channel with the buffer whose byte count diverges most from the other buffer byte counts as a channel containing a faulty storage device or faulty circuitry connecting the channel with the synchronization hardware.
