Technique for reordering hard drive activation reports to achieve sequential hard drive ordering
First Claim
Patent Images
1. A storage enclosure, comprising:
- a first hard drive configured to transmit a first activation report to an operating system upon activation;
a second hard drive configured to transmit a second activation report to the operating system upon activation; and
a logic device configured to;
receive the first activation report,receive the second activation report,reorder the first activation report and the second activation report according to a first order that is equivalent to an order of bays in a hard drive sub-board to which the first hard drive and the second hard drive are mounted; and
transmit the first activation report and the second activation report to the operating system according to the first order.

Abstract
A storage enclosure includes a plurality of hard drives coupled to a logic device that, in turn communicates with an operating system (OS) executing on a host computer system. When the storage enclosure is powered on, the hard drives become active at different times and transmit activation reports to the logic device in a random order. The logic device receives these activation reports, and then reorders then to align with the bay numbers where the hard drives are mounted. The logic device then transmits the reordered activation reports, and the OS assigns logical IDs to the hard drives that match the bay numbers.

19. A computer-implemented method for re-ordering activation reports, the method comprising:
-
receiving a first activation report transmitted by a first hard drive upon activation; receiving a second activation report transmitted by a second hard drive upon activation; reorder the first activation report and the second activation report according to a first order that is equivalent to an order of bays in a hard drive sub-board to which the first hard drive and the second hard drive are mounted; and transmitting the first activation report and the second activation report to an operating system according to the first order. - View Dependent Claims (20)
