Abstract
A disk administrating system is provided for administrating multiple disk-arrays containing at least one disk array. The disk administrating system comprises a computer with an interface card and a plurality of disk drives connected to the computer through the interface card. Part of the plurality of disk drives constitute to at least one disk array. The disk in the disk array has an array configuration sector located at the last sector thereof and storing array configuration information therein. The computer accesses the disk through the interface card and manages the disk array by information stored in the array configuration sector.
Claims7
A disk administrating system for disks in multiple disk-arrays containing at least one disk array, comprising:
- a computer having an interface card;
- a plurality of disk drives connected to said interface card;
- wherein said plurality of disk drives constitute at least one disk array, each of said disk drives having an array configuration sector located at a last of a plurality of sectors thereof;
- wherein said computer accesses said disk drives through said interface card and manages said disk array by information stored in said array configuration sector, said array configuration sector having a field identifying said disk drive as being part of a particular array, a disk array firmware identification field, an array information field, a disk information field, a first serial checksum and a second checksum, said first serial checksum being based on a model number, a serial number and a disk drive firmware revision number encoded in said disk information field, said second serial checksum being based on said fields of said array configuration sector, said computer identifying disk data directly from said serial checksum.
