1. Apparatus comprising:
- a first computing device which traverses a first boot list specifying bootable devices from which bootable code is retrievable for execution; and
a second computing device which is operatively accessible by said first computing device and which maintains a second boot list specifying bootable devices from which bootable code is retrievable for execution;
wherein said first computing device is configurable to include a predetermined entry in the first boot list, and in response to traversing the first boot list and encountering the predetermined entry, said first computing device issues a command to said second computing device, and wherein the second boot list is traversed in response to the issued command in search of boot code which is to be executed on said first computing device.

Abstract
An aggregated server blade system includes a plurality of individual server blades and a management module which can be designated as a bootable device. A boot list maintained and executed in each server blade includes a management module entry in its list of bootable devices. In response to the management module entry being selected or otherwise made active as the bootable device for a particular blade, an alternative bootable-devices list maintained on the management module is referenced and the boot process proceeds according to the alternative list.

4. Apparatus comprising:
-
a chassis;
a blade which is removably mountable into said chassis and which traverses a first boot list specifying bootable devices from which bootable code is retrievable for execution;
a management module which is removably mountable into said chassis and operatively accessible by said blade and which maintains a second boot list specifying bootable devices from which bootable code is retrievable for execution; and
a storage device which is accessible by said management module and which stores boot code therein;
wherein the second boot list is configurable to include said storage device, said blade is configurable to include a predetermined entry in the first boot list, and in response to traversing the first boot list and encountering the predetermined entry, said blade issues a boot command to said management module, and said management module traverses the second boot list in response to the issued boot command, and in response to encountering said storage device as the bootable device, accesses the boot code stored in said storage device and delivers the boot code to said blade. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. A method comprising:
-
traversing a first boot list which specifies bootable devices from which bootable code is retrievable for execution, the first boot list being maintained at a first computing device;
maintaining a second boot list specifying bootable devices from which bootable code is retrievable for execution, the second list being maintained at a second computing device;
wherein the first computing device is configurable for inclusion of a predetermined entry in the first boot list, and, in response to encountering the predetermined entry during said traversal of the first boot list by the first computing device, issuing a boot command from the first computing device to the second computing device;
receiving the boot command at the second computing device;
traversing the second boot list at the second computing device in response to said reception of the boot command; and
accessing boot code stored in a storage device listed in the second list and sending the boot code to the first computing device. - View Dependent Claims (13, 14, 15, 16, 17)

18. A product comprising:
-
a computer usable medium having computer readable program code stored therein, the computer readable program code in said product being effective to;
traverse a first boot list which specifies bootable devices from which bootable code is retrievable for execution, the first boot list being maintained at a first computing device;
maintain a second boot list specifying bootable devices from which bootable code is retrievable for execution, the second list being maintained at a second computing device;
wherein the first computing device is configurable for inclusion of a predetermined entry in the first boot list, and, in response to encountering the predetermined entry during said traversal of the first boot list by the first computing device, the code being further effective to;
issue a boot command from the first computing device to the second computing device;
receive the boot command at the second computing device;
traverse the second boot list at the second computing device in response to said reception of the boot command; and
access boot code stored in a storage device listed in the second list and sending the boot code to the first computing device. - View Dependent Claims (19, 20)
