Abstract

A method for recovering boot-up data in a computer system is provided. The method includes storing boot up data in a first container that is accessible by an operating system and copying the boot up data from the first container to a second container that is inaccessible by the operating system. If boot up using the boot up data from the first container fails, the method further includes copying the boot up data from the second container to the first container and booting up the computer system using the boot up data copied into the first container from the second container.

Claims (28)

1. A method for recovering boot up data comprising:

generating a first logical storage unit, the first logical storage unit being configured to be accessible by an operating system;

generating a second logical storage unit, the second logical storage unit being configured to be inaccessible by the operating system;

storing boot up data in the first logical storage unit;

copying the boot up data from the first logical storage unit to the second logical storage unit;

setting a recovery bit in a nonvolatile memory of a host adapter to initiate boot recovery; and

when the recovery bit is set,

copying the boot up data from the second logical storage unit to boot up data locations in the first logical storage unit;

booting up the computer system using the boot up data that was copied into the first logical storage unit from the second logical storage unit,

unsetting the recovery bit after the computer system has been booted up.

2. A method for recovering boot up data as recited in claim 1 , wherein setting the recovery bit includes receiving input to start recovery of the boot up data.

3. A method for recovering boot up data as recited in claim 1 , wherein the copying of the boot up data from the first logical storage unit to the second logical storage unit is managed by firmware being run in a host adapter.

4. A method for recovering boot up data as recited in claim 1 , wherein the second logical storage unit is an operating system secure sector.

5. A method for recovering boot up data as recited in claim 1 , wherein the second logical storage unit is at least a portion of at least one disk drive.

6. A method for recovering boot up data as recited in claim 1 , wherein the boot data includes at least a master boot record and system files.

7. A method for recovering boot up data as recited in claim 1 , wherein the first logical storage unit is accessible through firmware on a host adapter.

8. A method for recovering boot up data as recited in claim 1 , wherein the first logical unit is at least a portion of at least one storage device.

9. A method for recovering boot up data comprising:

generating a first logical storage unit, the first logical storage unit being configured to be accessible by an operating system;

generating a second logical storage unit, the second logical storage unit being configured to be inaccessible by the operating system;

storing boot up data in the first logical storage unit; and

determining the location of the boot up data as stored in firmware within a host adapter and copying the boot up data from the first logical storage unit to the second logical storage unit.

10. A method for recovering boot up data as recited in claim 9 , wherein the second logical storage unit is an operating system secure sector.

11. A method for recovering boot up data as recited in claim 9 , wherein the second logical storage unit is at least a portion of at least one disk drive.

12. A method for recovering boot up data as recited in claim 9 , wherein the boot data includes at least a master boot record and system files.

13. A method for recovering boot up data as recited in claim 9 , wherein the first logical storage unit is accessible through firmware on a host adapter.

14. A method for recovering boot up data as recited in claim 9 , wherein the first logical unit is at least a portion of at least one storage device.

15. A method for recovering boot up data as recited in claim 9 , wherein the copying is the boot up data from the first logical storage unit done by a firmware on a host adapter.
