In computing, rebooting is the process by which a running computer system is restarted, either intentionally or unintentionally. Reboots can be either "cold" (alternatively known as "hard") where the power to the system is physically turned off and back on again, causing an initial boot of the machine, or warm (alternatively known as soft) where the system restarts without the need to interrupt the power. The term restart is used to refer to a reboot when the operating system closes all programs and finalizes all pending input and output operations before initiating a soft reboot.
Software update method, apparatus and system
A system for remotely updating software on at least one electronic device connected to a network. The electronic devices have a non-volatile rewritable storage unit divided into at least two partitions, one of which will contain core firmware and the other of which will contain auxiliary software. When an update is received at the device, the updated core firmware is written to overwrite the partition in the rewritable storage unit that contained the auxiliary software. When this is completed and verified, the previous version of the core firmware stored in the storage unit is disabled from execution by the device. Next, the updated auxiliary software is written to overwrite the old version of the core firmware. When this write is complete, the device determines a suitable time for it to be rebooted to execute the updated software. In another embodiment, the present core firmware in the device is copied from the partition it is in to the other partition, overwriting the auxiliary software stored there. The new core firmware received to update the device is overwritten into the first partition, the old copied core firmware being present in case of an upgrade failure, and upon a successful update of the first partition, the auxiliary software is written to the second partition, overwriting the copied old core firmware. In this manner, the position of the core firmware and auxiliary software within the partitions is preserved during normal operation of the device.

Method and apparatus for remote installation of an operating system over a network connection
InactiveUS6963981B1More securityMemory loss protectionError detection/correctionOperational systemNetwork connection
A method for remote installation of a target operating system is carried out on a machine operating a source operating system. In one embodiment, it is presumed that the source operating system was booted from a first bootable region of a storage associated with the machine. According to the method, a copy of the source operating system together with the target operating system are delivered to the machine and stored in a second bootable region of the storage. The copy of the source operating system may be stored in a first partition of the second bootable region of the storage, and the target operating system may be stored in a second partition of the second bootable region. A boot loader is then configured to boot the copy of the source operating system from the second bootable region of the storage. The machine is then re-booted. At this point, the machine is still running the source operating system, although in this case that operating system was booted from the second bootable region of the storage. The original source operating system (from the first bootable region) is then removed, and the boot loader is re-configured to boot the target operating system from the second bootable region of the storage. The machine is then re-booted again, after which the target operating system is operational. In one embodiment, the first and second bootable regions may be separate hard disks, and the source and target operating systems are Linux and Windows, or vice versa.

Fast application notification in a clustered computing system
ActiveUS20050038772A1Resource allocationDigital data processing detailsComputer networkService experience
With fast notification of changes to a clustered computing system, through which a number of events are published for system state changes, applications can quickly recover and sessions can quickly be rebalanced. When a resource associated with a service experiences a change in status, such as a termination or a start / restart, a notification event is immediately published. Notification events contain information to enable subscribers to identify, based on matching a session signature, the particular sessions that are affected by the change in status, and to respond accordingly. This allows sessions to be quickly aborted and ongoing processing to be quickly terminated when a resource fails, and allows fast rebalancing of work when a resource is restarted.

Trusted modular firmware update using digital certificate
An over-the-air firmware update is accomplished in a secure manner using a two-step process. The first step uses an initial boot using a fixed boot program and an authenticated and verified secondary environment to complete starting of only authenticated code. After verifying a pending update, the second step is started with the electronic device being booted into an update mode with an update loader that has exclusive access to a signing key. A dummy update image is loaded into a temporary memory location and a hash is taken. A digital certificate is created corresponding to the update image and signed using the signing key. The update and digital certificate are atomically installed and the signing key is deactivated. Upon reboot, the new image is used for operation and is verified by the hash data and public key in the digital certificate.

Persistent snapshot methods
A persistent snapshot is taken and maintained in accordance with a novel method and system for extended periods of time using only a portion of a computer readable medium of which the snapshot is taken. Multiple snapshots can be taken in succession at periodic intervals and maintained practically indefinitely. The snapshots are maintained even after powering down and rebooting of the computer system. The state of the object of the snapshot for each snapshot preferably is accessible via a folder on volume of the snapshot. A restore of a file or folder may be accomplished by merely copying that file or folder from the snapshot folder to a current directory of the volume. Alternatively, the entire computer system may be restored to a previous snapshot state thereof. Snapshots that occurred after the state to which the computer is restored are not lost in the restore operation. Different rule sets and scenarios can be applied to each snapshot. Furthermore, each snapshot can be written to within the context of the snapshot and later restored to its pristine condition. Software for implementing the systems and methods of snapshots in accordance with the present invention may comprise firmware of a hard disk drive controller or a disk controller board or within the HDD casing itself. The present invention further comprises novel systems and methods in which the systems and methods of taking and maintaining snapshots are utilized in creating and managing temporal data stores, including temporal database management systems. The implications for data mining and exploration, data analysis, intelligence gathering, and artificial intelligence (just to name a few areas) are profound.

A virtual machine is suspended and quickly restarted while maintaining the VM's state. The method is quick enough so that network connections are maintained across the restart and the guest operating system and guest applications running in the VM are not aware of the restart. As a result, users and clients connected to the VM do not notice any downtime or disruption to the VM. After suspension and before the restart, VM configuration changes that would not be possible or be very difficult through code changes alone while the VM was running can be made.

A computer system having a fault-tolerance framework in an extendable computer architecture. The computer system is formed of clusters of nodes where each node includes computer hardware and operating system software for executing jobs that implement the services provided by the computer system. Jobs are distributed across the nodes under control of a hierarchical resource management unit. The resource management unit includes hierarchical monitors that monitor and control the allocation of resources. In the resource management unit, a first monitor, at a first level, monitors and allocates elements below the first level. A second monitor, at a second level, monitors and allocates elements at the first level. The framework is extendable from the hierarchy of the first and second levels to higher levels where monitors at higher levels each monitor lower level elements in a hierarchical tree. If a failure occurs down the hierarchy, a higher level monitor restarts an element at a lower level. If a failure occurs up the hierarchy, a lower level monitor restarts an element at a higher level. Each of the monitors includes termination code that causes an element to terminate if duplicate elements have been restarted for the same job. The termination code in one embodiment includes suicide code whereby an element will self-destruct when the element detects that it is an unnecessary duplicate element.

System and method for fast reboot of a file server
InactiveUS6965989B1Fast (“warm”) rebootReduce server downtimeDigital computer detailsData resettingOperational systemDowntime
A system and method for fast (“warm”) reboot of a file server is provided, which skips certain conventional boot processes when circumstances warrant, in order to reduce server downtime. In particular, time is saved by avoiding a full shutdown of the processor and memory, and by causing the firmware to refrain from a full clearance of the file server memory. Instead, the firmware accesses a retained copy of the storage operating system kernel from a reserved location in the file server memory so that an operative version of the kernel is reestablished at the appropriate address space in memory without requiring a time-consuming read of the kernel image from disk. In addition, other “normal” (cold) reboot operations such as full memory tests, hardware checks and memory zeroing are avoided as appropriate—saving further time in the overall reboot process, while still attaining the desired reinitialization of key applications and functions.
