Status display system for storage device
First Claim
1. A status display system for a storage device including at least one logic device addressing physical memory locations on a plurality of physical devices, and a plurality of device control means for controlling operations of said physical devices of a corresponding logic device in accordance with a given command from a host device, wherein said system comprises:
- status information generating means operatively connected to each of the physical devices for generating status information indicating the present operational condition of the logic device, based on information about operational condition of the physical devices of the corresponding logic device;
wherein said status information generating means, after being informed of the present operational condition of at least one physical device from a corresponding control means, request a confirmation from other control means that correspond to physical devices of the corresponding logic device and wait for a reply from said other control means, so as to generate said status information of the logic device anddisplay means for displaying said status information of the logic device generated by said status information generating means.
