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.

Important product data returned by the SCSI target to determine whether the initiator operating system can be shut down, so as to avoid potential loss and crash of key system data.

Since the shutdown monitoring module regularly sends SCSI commands to the SCSI target, instead of directly sending the SCSI command to the SCSI target, it sends the SCSI command to the SCSI target of the target device controller through the SCSI initiator located in the operating system of the initiator. Therefore, the The shutdown monitoring module regularly sends SCSI commands to the SCSI target, including:

The shutdown monitoring module regularly sends the SCSI command to the SCSI target through the SCSI initiator.

After the SCSI target receives the SCSI command, the SCSI target does not directly store the request for shutting down the operating system of the initiator, but obtains it from the important product data page of the target device controller. Therefore, the SCSI target end receives the SCSI command and replies with the important product number to the shutdown monitoring module, including:

The SCSI target end receives the SCSI command, obtains the important product number reply data from the important product data page, and sends the important product data to the shutdown monitoring module.
