Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to the management of information handling systems. More specifically, embodiments of the invention provide a system, method, and computer-readable medium for performing an operating system boot operation using a service location protocol and launching the operating system using a dynamic update of network boot order within a reboot.

Description of the Related Art

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

One issue that relates to information handling systems occurs when performing operating system (OS) deployments. More specifically, when performing an OS deployment via a network mode of operation (e.g., using an Internet Small Computer System Interface (iSCSI) or Fibre Channel over Ethernet (FCOe) where the OS media is accessed via the iSCSI or FCOe Logical Unit Number (LUN)) it is important to be able to detect network settings. It is also important to initiate the OS deployment from the network location. When performing the OS deployment, the network stack (which includes Basic Input Output System (BIOS) and/or a Unified Extensible Firmware Interface (UEFI)) authenticates and changes the boot order within the information handling system to add the network devices at the next boot. When a change in BIOS boot order is performed, it is necessary for the information handling system reboot, likely losing all established authentication information. FIG. 1, labeled Prior Art, shows a flow chart of a boot mapping operation.

SUMMARY OF THE INVENTION

A system, method, and computer-readable medium are disclosed for providing a boot mapping system. More specifically, in certain embodiments, BIOS of an information handling system includes a boot mapping system which allows the information handling system to boot up regardless of a boot order change in a network mode of operation or a BIOS boot order change. Additionally, in certain embodiments, the boot mapping system further includes a service location protocol (SLP) which locates OS images based on the type of network protocol selected for deployment. More specifically in certain embodiments, when the network protocol corresponds to Network File System (NFS), Common Internet File System (CIFS), Preboot eXecution Environment (PXE) and/or ISCSI based protocol, then during OS Deployment, the boot mapping system provides an updated network boot order which uses the service location protocol to determine any services which may be needed for the network operating system deployment. For example if the network protocol corresponds to an NFS client then the boot mapping tool accesses a UEFI based management tool, locates the OS image from an NFS server and continues with the OS boot operation. Additionally, in certain embodiments, the SLP is stored within an SLP server on the network as part of the install infrastructure. Additionally, in certain embodiments the SLP server is included within an install infrastructure which further includes NFS, ISCSI and FCoE infrastructure.

FIG. 2 is a generalized illustration of an information handling system 200 that can be used to implement the system and method of the present invention. The information handling system 200 includes a processor (e.g., central processor unit or “CPU”) 202, input/output (I/O) devices 204, such as a display, a keyboard, a mouse, and associated controllers, a hard drive or disk storage 206, and various other subsystems 208. In various embodiments, the information handling system 200 also includes network port 210 operable to connect to a network 240, which is likewise accessible by a server 242. The information handling system 200 likewise includes system memory 212, which is interconnected to the foregoing via one or more buses 214. System memory 212 further comprises operating system (OS) 216 and in various embodiments may also comprise a boot mapping system 226. In one embodiment, the information handling system 200 is able to download the boot mapping system 226 from the server 242. In another embodiment, the boot mapping system 226 is provided as a service from the server 242.

More specifically, in certain embodiments, BIOS of an information handling system includes the boot mapping system 226 which allows the information handling system 200 to boot up regardless of a boot order change in a network mode of operation or a BIOS boot order change. Additionally, in certain embodiments, the boot mapping system 226 further includes a service location protocol (SLP) which locates OS images (e.g., from server 242) based on the type of network protocol selected for deployment. More specifically in certain embodiments, when the network protocol corresponds to Network File System (NFS), Common Internet File System (CIFS), Preboot eXecution Environment (PXE) and/or ISCSI based protocol, then during OS Deployment, the boot mapping system 226 provides an updated network boot order which uses the service location protocol to determine any services which may be needed for the network operating system deployment. For example if the network protocol corresponds to an NFS client, then the boot mapping system 226 accesses a UEFI based management tool, locates the OS image from an NFS server and continues with the OS boot operation. Additionally, in certain embodiments, the SLP is stored within an SLP server on the network as part of the install infrastructure. Additionally, in certain embodiments the SLP server is included within an install infrastructure which further includes NFS, ISCSI and FCoE infrastructure. In various embodiments, the server 242 may correspond to one or more of the NFS server, the SLP server as well as the iSCSI and FCoE infrastructure.

For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.

Referring to FIG. 3, a flow chart of the operation of a boot mapping system 226 in accordance with the present invention is shown. More specifically, at step 310, the boot mapping system 226 determines that an OS deployment is to be enabled on via e.g., a preboot Unified Extensible Firmware Interface (UEFI) type management tool. The boot mapping system 226 identifies the service required for OS Deployment (e.g., whether an NFS service, a CIFS service, an iSCSI service, an FCoE service is to be used for OS Deployment. Next, at step 330, the boot mapping system 226 enables a service location protocol to check for servers hosting the Services required from the host for OS deployment such as NFS based servers for OS deployment, CIFS or iSCSI based. Next, at step 320, the boot mapping system 226 enables an Internet Protocol (IP) On the Host operation using a Dynamic Host Configuration Protocol (DHCP) service. Next, at step 340, the boot mapping system 226 updates a network boot order for the information handling system. In certain embodiments, the boot mapping system uses a BIOS operation such as a one shot boot order operation to boot to a network location selected for performing the OS boot. The one shot boot feature bypasses the standard BIOS boot behavior (i.e., the boot sequence) to directly boot to any targeted boot device. This is a temporary bypass operation (i.e., a one shot feature). Subsequent boots revert to the standard BIOS boot behavior. Finally, at step 350, the boot mapping system 226 continue the OS boot operation without requiring a reboot of the information handling system.

By using the boot mapping system 226, a PXE boot operation may be eliminated as this type of boot operation is potentially insecure due to the Trivial File Transfer Protocol (TFTP) protocol used for file transfer during this type of boot operation. Additionally, the boot mapping system 226 provides support for OS deployment across varied network clients such as CIFS, NFS, FCoE, iSCSI with authentication enabled for secure OS deployment and OS Boot. Additionally, the boot mapping system 226 saves time when performing an OS deployment as there is no need for reboot for every network order configuration such as by using a BIOS one shot boot menu order configuration.
