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.
