Problems solved by technology

In the application process of some SAS cards, when multiple hard drives are used, the boot sequence of the hard drives cannot be guaranteed to be consistent with the physical connection sequence of the hard drives
For example, assuming that the operating system is installed on the first hard disk in the physical connection sequence, the startup sequence of the hard disk may change when the next startup is performed, and the first hard disk to start may not be the first hard disk in the physical connection. It is difficult to ensure that the boot sequence of the hard disk is consistent with the physical connection sequence of the hard disk, resulting in the inability to start the operating system. In the prior art, it is impossible to adjust the boot sequence of the SAS card hard disk.

Abstract

The invention provides a method and a device for regulating a boot sequence of an SAS (Serial Attached SCSI) card hard disk. The method comprises the following steps: determining a headmost SAS card hard disk which is started in advance; determining all SAS card hard disks, and obtaining the SASIndex of all SAS card hard disks; traversing all pieces of BootOption, and determining the BootOption corresponding to each SASIndex; according to the SAS card hard disk corresponding to each SASIndex and the BootOption corresponding to each SASIndex, determining the BootOption corresponding to each SAS card hard disk; and according to the determined headmost SAS card hard disk, determining the value of Priority in the BootOption corresponding to all SAS card hard disks. The method and the device for regulating the boot sequence of the SAS card hard disk can regulate the boot sequence of the SAS card hard disks.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and a device for adjusting the startup sequence of a SAS card hard disk. Background technique [0002] SAS (Serial Attached SCSI, Serial Attached SCSI) is a new generation of SCSI technology, which is the same as the popular SATA (Serial Advanced Technology Attachment, Serial Advanced Technology Attachment) hard disk, and uses serial technology to obtain higher transmission speed, and improved internal space by shortening the connecting lines, etc. SAS is a new interface developed after the parallel SCSI interface. This interface is designed to improve the performance, usability and expandability of the storage system and provide compatibility with Serial ATA hard disks. As a new storage interface technology, SAS is not only comparable to Fiber Channel in function, but also compatible with SATA, so it is recognized by the industry as the best choice to replace parall...
