Automatic disk drive shelf address assignment and error detection method and apparatus |
摘要 |
Automatic shelf-to-shelf address assignment is provided for a plurality of disk drive supporting shelves that are removably contained within a multi--shelf cabinet. Error detection apparatus detects failure in the automatic assignment of shelf addresses. An address input of shelf-N receives a shelf addressing voltage from shelf N+1. Shelf-N checks to ensure that the received shelf-N address voltage is within a correct range. Where-N now increases its shelf-N address by one and applies this incremented address to an address input of shelf-N+1. Accuracy of the shelf-N+1 address input is checked, as are the cable/connectors that connect shelf-N to shelf-N+1. ADC and ADC techniques are used, and operation of the automatic address assignment system is timed.
