Embodiment Construction

[0032] As mentioned in the background technology section, in some cases, the SCSI standard target controller is required to be offline, and the initiator operating system is not shut down safely, and serious consequences will be produced at this time. Potential damage includes data loss and corruption of critical operating system data.

[0033] Based on this, an embodiment of the present invention provides a method for safely shutting down the operating system of the initiator, including:

[0034] The shutdown monitoring module regularly sends SCSI commands to the SCSI target end to inquire whether to perform a shutdown operation on the initiator operating system;

[0035] The SCSI target end receives the SCSI command and replies important product data to the shutdown monitoring module;

[0036] The shutdown monitoring module receives and analyzes the important product data, and obtains analysis results;

[0037] Judging whether the analysis result indicates that the initiat...

Abstract

The invention discloses a method and an assembly for safely closing an initial end operating system. The method comprises the following steps that: a closing monitoring module transmits an SCSI instruction to an SCSI objective end at certain time for inquiring whether to execute a closing operation on the initial end operating system or not; the SCSI objective end receives the SCSI instruction and replies important product data to the closing monitoring module; the closing monitoring module receives and analyzes the important product data to obtain an analysis result; whether the analysis result indicates that the initial end operating system needs to be closed or not is determined; and if so, the initial end operating system is closed. According to the method, by adding the closing monitoring module at the initial end operating system, and by analyzing the important product data returned by the SCSI objective end, whether the initial end operating system can be closed or not can be determined, so that potential loss and crash of key system data can be avoided consequently.

Description

technical field [0001] The invention relates to the technical field of computer system software design, in particular to a method and components for safely shutting down an operating system at an initiator. Background technique [0002] In some cases, the SCSI (Short for Small Computer System Interface, small computer system interface) standard target controller is required to be offline, for example: the equipment operator issues instructions, the main power supply of the equipment is lost, or the presence of The conditions for data consistency risk are met. In the event of these events, the target controller goes offline without the initiator operating system being shut down safely, which can have serious consequences. Potential damage includes data loss and corruption of critical operating system data. Therefore, there is a need for a method of safely shutting down an operating system to avoid potential loss and crash of critical system data. Contents of the invention...
