Embodiment Construction

[0025] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0026] Such as figure 1 As shown, a method for out-of-band self-test fault isolation includes the following steps:

[0027] Step 1, when the system starts, through the out-of-band management subsystem BMC, monitor all the devices in the system through the monitoring channel;

[0028] Step 2: Obtain the startup status of each device in the system at startup. If the startup status of the device is detected to be abnormal, record the relevant abnormal status information and the corresponding device information and store them in the error status register, judge the abnormal status, and check the status of different abnormal status. Three-level state classification, according to the state classification, adopt the isolation method corresponding...

Abstract

The invention discloses a method for out-of-band self-test fault isolation, which includes monitoring all equipment in the system through a monitoring channel when the system is started; obtaining the startup status of each device in the system when the system is started, and classifying the status of different abnormal states, According to the state classification, the isolation method of the corresponding state classification is adopted to complete the isolation of the equipment with abnormal state, and the system enters operation; after the system enters operation, it detects whether there is a new abnormal equipment at the same time, if not, completes fault isolation; if there is, Then first match the abnormal device in the new state. If the same device information is matched, it is judged that the device is an unstable device; if the same device information is not matched, the device is judged to be a new faulty device, and fault detection and isolation are performed . Through the present invention, proactive detection of system faults can be realized in advance, and high-risk fault types that may cause system hang-up and reset can be actively identified, so as to ensure normal operation of system software.

Description

technical field [0001] The invention relates to the field of server systems, in particular to a method for out-of-band self-test fault isolation. Background technique [0002] In the current server system, when the system starts, it mainly relies on the BIOS to initialize and configure the CPU, memory, and PCIe peripherals. Possible potential failure of memory. But there is no fault detection for peripherals. It is very likely that the system cannot be started or hangs abnormally during operation due to the failure of these peripherals. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and a kind of method for out-of-band self-test fault isolation is provided, comprising the steps: [0004] Step 1, when the system starts, through the out-of-band management subsystem BMC, monitor all the devices in the system through the monitoring channel; [0005] Step 2: Obtain the startup status of each device in...
