Examples disclosed herein relate to an error coordination message for a blade device having a logical processor in another system firmware (SFW) domain. Examples include a partition of a blade system to run an operating system (OS) utilizing blade devices including respective logical processors operating in different SFW domains. Examples further include an error coordination message made available to one of the blade devices by another of the blade devices.

Error coordination message for a blade device having a logical processor in another system firmware domain

Examples disclosed herein relate to making memory of compute and expansion blade devices available for use by an operating system (OS). Examples include making available, for use by an OS, a compute logical processor of the compute blade device, identified memory of the compute blade device, and identified memory of an expansion blade device. Examples further include making the expansion logical processor unavailable to the OS.

Making memory of compute and expansion devices available for use by an operating system

Examples disclosed herein relate to identifying memory of a blade device for use by an operating system (OS) of a partition including the blade device. Examples include identifying memory of a first blade device associated with a first logical processor of the first blade device for use by an OS of a partition including the first blade device and a second blade device, wherein the OS is executed by at least a second logical processor of the second blade device.

Identifying memory of a blade device for use by an operating system of a partition including the blade device

According to one embodiment, a method comprises, responsive to detection of loss of lockstep (LOL) for a processor module in a system, setting status information stored to the system for the processor module to indicate that the processor module has an error. The method further comprises reestablishing lockstep for the processor module without shutting down the system's operating system, and updating the status information for the processor module to indicate that the processor module no longer has the error. The method further comprises causing the system's operating system to recognize that the processor module having its lockstep reestablished is available for processing.

System and method for reintroducing a processor module to an operating system after lockstep recovery

According to one embodiment, a method comprises system firmware instructing a system's operating system to idle a processor, and responsive to the instructing, the operating system idling the processor and returning control over the processor to the system firmware. According to one embodiment, a method comprises detecting loss of lockstep (LOL) for a processor module in a system, and responsive to the detecting LOL for the processor module, system firmware instructing an operating system to idle the processor module.
