Abstract:
Systems and arrangements for remotely selecting a bootable image via a WOL packet for a wake-on-LAN (WOL) capable computer are contemplated. Server-side embodiments include hardware and/or software for determining a client to be managed, determining whether the client is active on the network, and transmitting a WOL packet having a vector, or operating system partition identification (OSPID), to describe a bootable image accessible by the WOL capable computer. Some embodiments may include an OSPID that points to a secure bootable image such as a bootable image on a hard drive, a compact disk (CD) connected to the computer, or other local resource. Client-side embodiments may receive the WOL packet at, for instance, a network interface card (NIC), recognize that the WOL packet includes an OSPID that describes the bootable image to boot, and implement an alternative boot sequence to boot from that bootable image.

Abstract:
Local drive presence is provided for local and remote drives by maintaining a plurality of uninterrupted protocol connections between a plurality of I/O controllers and a plurality of device interfaces through which peripheral bus commands are transmitted. Preferably, the I/O controllers are each housed in a separate server blade and provide each blade with access to the local and remote drives. At each of the device interfaces, rather than attaching an actual storage device, peripheral bus commands received at the device interfaces are serialized and conditionally passed or suppressed to and from the shared drive which is shared amongst the plurality of uninterrupted protocol connections. Preferably, the plurality of uninterrupted protocol connections is maintained such that the shared drives can be simultaneously shared. In one embodiment, the local drives are provided in a media tray which is shared amongst a plurality blades.
Abstract:
A system, method, and computer program product for reporting and recovering from an internal processor error in a multiprocessor system supporting system management mode. In accordance with the method of the present invention one or more replacement agents are allocated such as during system startup within the multiprocessor system. Machine specific error-reporting registers are monitored for one or more active processor agents during system operation. In response to detecting a faulty agent via the monitoring, a system management interrupt (SMI) request is issued to one or both the faulty agent and a selected replacement agent. In response to receiving the SMI request, the operating state of the faulty agent is copied to the selected replacement agent in system management mode. Operating system processing is then resumed using the replacement agent.
Abstract:
A method and system for accessing a remote real communication port (“COM port”) from a server blade in a server blade chassis by creating a virtual COM port in the server blade. A basic input/output system (BIOS) controller monitors an internal COM port in the server blade for communication traffic. Upon detecting the communication traffic, the BIOS controller reroutes the traffic to a virtual USB COM port created by the BIOS controller chipset. The virtual USB COM port directs the communication traffic to an internal universal serial bus (USB) device in the server blade. The USB device then forwards the traffic to an Ethernet media access controller (MAC) input/output (I/O) on a sideband channel to a remote system, which passes the communication traffic to a real COM port in the remote system.

Abstract:
A method and system are disclosed for substituting an anonymous Universal Unique Identifier (UUID) for a computer system's real UUID in order to disguise an identity of the computer system to an application which is requesting a UUID for the client computer system. A storage device is established in the computer system. The storage device includes a primary and a second location. A UUID stored in the primary location is used as a UUID for the computer system. An anonymous UUID is generated. The anonymous UUID does not identify any particular computer system. The anonymous UUID is stored in the primary location within the storage device, and the real UUID is backed up by moving it into the secondary location. Thereafter, the anonymous UUID is provided in response to requests for the computer system's UUID.
Abstract:
A method, system and computer readable medium containing programming instructions for booting a computer system having a plurality of devices is disclosed. They include provisions for initiating a boot sequence in the computer system and determining whether a device of the plurality of devices is either a bootable device or a nonbootable device. If the device is a nonbootable device, a clean restart of the boot sequence is performed, wherein the nonbootable device is bypassed during the clean restart.
Abstract:
A data processing system and method are disclosed for authenticating a client computer system to a secure network prior to permitting the client computer system to attempt to log-on to the network. The secure network is controlled by a server computer system. A unique identifier is established which identifies the client computer system. The unique identifier is encrypted. Prior to permitting the client computer system to attempt to log-on to the secure network, the client computer system transmits the encrypted identifier to the server computer system. Also prior to permitting the client computer system to attempt to log-on to the network, the server computer system utilizes the unique identifier to determine whether to permit the client computer system to attempt to log-on to the network. The client computer system is authenticated prior to permitting the client computer system to attempt to log-on to the network.
Abstract:
A data processing system and method including a server computer system and a client computer system coupled together utilizing a network are described for permitting the client computer system to temporarily prohibit remote management of the client computer system. The client computer system sets a remote override condition in the client computer system for temporarily prohibiting remote management of the client. The client temporarily prohibits all attempts to manage the client remotely utilizing the network when the remote override condition is set.
