Filed:

Mar 29, 2002

Appl. No.:

10/113338

Inventors:

Richard Christopher Fore - Apex NC, US
Vikram Harakere Krishnamurthy - Durham NC, US
Luis Rene Quinones - Raleigh NC, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 11/00

US Classification:

714 7, 714 6, 714 15

Abstract:

A method, system and computer program product for performing an expansion of a disk array. Upon the failure of a disk in the disk array, the failed disk may be rebuilt stripe by stripe in the spare units distributed among other disks in the disk array. Upon repairing or replacing the failed disk with a spare disk, the repaired or spare disk may be rebuilt stripe by stripe using the data from the spare units. Upon receiving a write request to a stripe unit that has been rebuilt in the repaired or spare disk during expansion, the data of the request may be written in the stripe unit requested. Further, the data written may be mirrored, i. e. , copied and stored, in the spare unit corresponding to the stripe unit requested. By mirroring the data to the corresponding spare unit, tracking each stripe that was updated during expansion may be eliminated.

International Classification:

G06F 9/44

Abstract:

At initiation of boot of a computing device, a processor executes a firmware interface of the computing device, like a basic input/output system (BIOS) or a unified extended firmware interface (UEFI). The processor executes the firmware interface to detect whether a dynamic hardware configuration (DHC) function has been enabled. In response to detecting that the DHC function has been enabled, the processor executes the firmware interface to configure hardware components of the computing device according to a DHC, such as to selectively disable the hardware components. After configuring the hardware components according to the DHC, the processor proceeds to boot the computing device.

Abstract:

A method includes running a system mainline initialization process on a compute node that includes an expansion card with read-only memory storing expansion card initialization code. The method obtains and executes the expansion card initialization code from the read-only memory to perform initialization of the expansion card. The method further includes updating a current operational progress state of the expansion card initialization stored in non-volatile memory of the node as the expansion card initialization moves through a plurality of operational progress states, detecting a fault, such as a hung condition, during the expansion card initialization in response to exceeding a predetermined time period in the current operational progress state, and storing a fault indication in the non-volatile memory, wherein the fault indication identifies the card experiencing the fault. Optionally, the method may reset the node and bypass initializing the card associated with the fault indication.

International Classification:

G06F 11/22
G06F 11/30

Abstract:

A method for tracking a pluggable component associated with an electronic device is provided. The method may include identifying at least one field of vital product data (VPD) information associated with the pluggable component. The method may also include decoding the at least one field of VPD information. Additionally, the method may include determining, based on the decoding of the at least one field, when a hardware id associated with the pluggable component is valid. The method may further include generating a pairing signature based on the hardware id being valid.
