Abstract

Claims (19)

1. A method for provisioning a blade server, comprising:

creating a server boot image for a blade server, the boot image includes an operating system image created from a donor server;

inserting the blade server into a chassis of an enclosure that is capable of receiving multiple blade servers;

staring the blade server from a pre-boot execution environment (PXE), the PXE loading an image that prompts a user to install a new operating system from a pre-existing target computer of the enclosure;

installing the new operating system, the installing including creation of a new iSCSI target for the inserted blade server, and partitioning of the iSCSI target; and

restarting the inserted blade server, the restarting configured to boot using the iSCSI target of the inserted blade server, so that the inserted blade server is a provisioned blade server.

2. A method for provisioning a blade server as recited in claim 1 , wherein the operating system pre-installs files that are copied to the iSCSI target, so that the reinstalled files are local copies within the provisioned blade server.

3. A method for provisioning a blade server as recited in claim 2 , wherein the inserted server blade restarts, and using an iSCSI connection or a PXE assisted boot, connects back to the iSCSI target and completes a remaining automated portion of the install of the operating system.

4. A method for provisioning a blade server as recited in claim 1 , wherein the iSCSI target includes configuration data that includes data necessary to invoke software components to retrieve IQNs from a newly added blade server and software components to retrieve appliance configuration information including a list of iSCSI targets coupled to the appliance.

5. A method for provisioning a blade server as recited in claim 1 , wherein the provisioning is accomplished without a hardware iSCSI initiator for an iSCSI boot.

6. A method for provisioning a blade server, comprising:

creating a server boot image for a blade server, the boot image includes an operating system image created from a donor server;

inserting the blade server into a chassis of an enclosure that is capable of receiving multiple blade servers;

staring the blade server from a pre-boot execution environment (PXE), the PXE loading an image that prompts a user to install a new operating system from a pre-existing target computer of the enclosure;

installing the new operating system, the installing including creation of a new iSCSI target for the inserted blade server, and partitioning of the iSCSI target; and

restarting the inserted blade server, the restarting configured to boot using the iSCSI target of the inserted blade server, so that the inserted blade server is a provisioned blade server, wherein the provisioning is accomplished without a hardware iSCSI initiator for an iSCSI boot.

7. A method for provisioning a blade server as recited in claim 6 , wherein the operating system pre-installs files that are copied to the iSCSI target, so that the reinstalled files are local copies within the provisioned blade server.

8. A method for provisioning a blade server as recited in claim 7 , wherein the inserted server blade restarts, and using an iSCSI connection or a PXE assisted boot, connects back to the iSCSI target and completes a remaining automated portion of the install of the operating system.

9. A method for provisioning a blade server as recited in claim 6 , wherein the iSCSI target includes configuration data that includes data necessary to invoke software components to retrieve IQNs from a newly added blade server and software components to retrieve appliance configuration information including a list of iSCSI targets coupled to the appliance.
