Method and device for adjusting starting sequence of hard disk in presence of operating system

Abstract

The invention discloses a method for adjusting the starting sequence of a hard disk in the presence of an operating system. A root port is set into a link disabled state before the root port where an SAS card is located is scanned, so that the system can not detect the SAS card when peripheral component interconnect standard scanning is conducted in the presence of the operating system; after an operating system drive device completes loading of the SATA hard disk, the root port is set into a link enabled state, so that the system can detect the SAS card, the operating system drive device conveniently completes initialization of the SAS card and loading of the hard disk connected with the SAS card, such a scheme that a customized system is used for operating kernel or customized SAS cards and other kinds of component firmware is avoided, and under the condition of the lower cost, the adjustment of the starting sequence of the hard disk in the presence of the operating system can be completed. The invention further discloses a device for adjusting the starting sequence of the hard disk in the presence of the operating system, the device includes a disabled module and an enable module, and the effects are as above.

Description

technical field [0001] The invention relates to the field of servers, in particular to a method and device for adjusting the startup sequence of a hard disk under an operating system. Background technique [0002] As the core of the entire network system and computing platform, the server needs to store a lot of important data. Generally, the onboard Serial Advanced Technology Attachment (SATA) hard disk and the hard disk connected to the serial connection Small Computer System Interface (SAS) card will be equipped as standard. , and users generally install the operating system on the onboard SATA hard disk, and use the hard disk connected to the SAS card as a storage disk. Therefore, users prefer to start the SATA hard disk first, and then start the hard disk connected to the SAS card. However, under normal circumstances, since the operating system detects and loads the hard disk drive in a serial manner, the hard disk connected to the SAS card in the physical order starts ...

AI Technical Summary

Problems solved by technology

However, under normal circumstances, since the operating system detects and loads the hard disk drive in a serial manner, the hard disk connected to the SAS card in the physical sequence starts before the SATA hard disk.

[0003] In the prior art, although it is possible to adjust the boot sequence of the hard disk under the operating system through a solution of a customized system operating kernel (OS Kernel) or a customized SAS card and other component firmware (Firmware), since these two solutions all need to be customized, So the cost is higher

Moreover, if the solution of customized OS Kernel or customized SAS card and other component firmware is adopted, some adaptive adjustments have to be made during the user's use, which also brings inconvenience to the user.
