Abstract

Claims (34)

1. A method for managing boot trace information, comprising:

configuring a host bus adapter for collecting boot trace information for a plurality of modules during a boot operation;

wherein the plurality of modules include basic input and output system (BIOS) code, extended firmware interface code (EFI) and a host bus adapter driver executed by the host system;

wherein a utility module sets a level for each of the plurality of modules based on which boot trace information for each of the plurality of modules is collected;

enabling boot trace collection in the host bus adapter, wherein the utility module enables boot trace collection for the plurality of modules;

saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if hardware initialization fails;

saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if host bus adapter firmware loading is unacceptable;

saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if a BIOS host system initialization is unacceptable; and

saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if target discovery is improper.

2. The method of claim 1 , wherein the utility module sets different trace levels for each of the plurality of modules.

3. The method of claim 1 , wherein the utility module configures boot trace buffers that are cleared upon initialization.

4. The method of claim 1 , wherein the utility module defines memory addresses where boot trace information is stored at the non-volatile memory of the host bus adapter.

5. A system for managing boot trace information, comprising:

a utility module executed by a computing system processor that:

(a) configures a host bus adapter for collecting boot trace information for a plurality of modules during a boot operation;

wherein the plurality of modules include basic input and output system (BIOS) code, extended firmware interface code (EFI) and a host bus adapter driver executed by the host system; and

wherein the utility module sets a level for each of the plurality of modules based on which boot trace information for each of the plurality of modules is collected; and

(b) enables boot trace collection in the host bus adapter, wherein the utility module enables boot trace collection for the plurality of modules and boot trace information is stored in a designated area of a non-volatile memory of the host bus adapter, if hardware initialization fails; if firmware loading is unacceptable; if BIOS initialization is unacceptable; and if target discovery is improper.

6. The system of claim 5 , wherein the utility module sets different trace levels for each of the plurality of modules.

7. The system of claim 5 , wherein the utility module configures boot trace buffers that are cleared upon initialization.

8. The system of claim 5 , wherein the utility module defines memory addresses where boot trace information is stored at the non-volatile memory of the host bus adapter.

9. The system of claim 5 , wherein the utility module defines memory addresses where boot trace information is stored at the non-volatile memory of the host bus adapter.

10. Computer-executable process steps stored on computer-readable media for managing boot trace information, comprising:

code configuring a host bus adapter for collecting boot trace information for a plurality of modules during a boot operation;

wherein the plurality of modules include basic input and output system (BIOS) code, extended firmware interface code (EFI) and a host bus adapter driver executed by the host system;

wherein a utility module sets a level for each of the plurality of modules based on which boot trace information for each of the plurality of modules is collected;

code for enabling boot trace collection in the host bus adapter, wherein the utility module enables boot trace collection for the plurality of modules;

code for saving boot trace information in a designated area of a non-volatile memory of the host bus adapter, if hardware initialization fails;

code for saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if host bus adapter firmware loading is unacceptable;

code for saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if a BIOS host system initialization is unacceptable; and

code for saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if target discovery is improper.

11. Computer-executable process steps of claim 10 , wherein the utility module sets different trace levels for each of the plurality of modules.

12. Computer-executable process steps of claim 10 , wherein the utility module configures boot trace buffers that are cleared upon initialization.

13. Computer-executable process steps of claim 10 , wherein the utility module defines memory addresses where boot trace information is stored at the non-volatile memory of the host bus adapter.
