Problems solved by technology

[0005] In the existing microcode version upgrade, if there is a hardware failure or a software bug is triggered, the upgrade will fail, causing the microcode version to roll back (restore to the version before the upgrade), or even business interruption, resulting in the microcode version upgrade low success rate

Embodiment Construction

[0052] It should be noted that, in the implementation of the present invention, for simplicity of description, the storage system may be abbreviated as system, and the microcode version upgrade of the storage system may be abbreviated as system upgrade.

[0053] The system upgrade method and system upgrade device provided by the embodiments of the present invention can be applied to the microcode version upgrade of multi-component (or component) products, such as storage systems. By dividing the upgrade process of the entire microcode version into multi-stage upgrades, and setting the expected target state after each stage upgrade is completed, it is identified by comparing the state of the components (including version information and working status information of the components) Components that need to be upgraded and the results after the upgrade. When the components do not reach the expected target state of each stage after the upgrade, the system will automatically suspend...

Abstract

The invention relates to a system upgrade method and a system upgrade device. The upgrade method is executed by a master controller and comprises the steps that an upgrade target state of a first attachment is updated to be a first expected target state; a second attachment is determined according to the state of the first attachment and the first expected target state; a slave controller is instructed to upgrade the second attachment, and whether the state of the second attachment after upgrade reaches the first expected target state is determined; and when the state of the second attachment after upgrade does not reach the first expected target state, the slave controller is instructed to suspend upgrade, and fault report information of failure in upgrade to be the first expected target state of the second attachment is instructed. System upgrade is performed at multiple stages, the states of all the attachments are compared with the expected target state at all the upgrade stages, and when the states of the attachments do not reach the expected target state, the system suspends upgrade, and prompts the fault report information, in this way, it is convenient to perform manual intervention processing according to the fault report information to remove reported faults, and the success rate of system upgrade is increased.

Description

technical field [0001] The invention relates to the field of storage systems, in particular to a system upgrading method and a system upgrading device. Background technique [0002] With the rapid development of computer technology and network technology, the built-in memory of the computer is gradually difficult to meet many requirements such as fast access speed, large storage capacity and low cost, so a relatively independent storage system has been developed. The storage system is usually composed of storage devices such as storage servers, which have their own interfaces and protocols, and are connected to the computer host through coaxial cables, network cables, optical fibers, etc., and serve as a data storage center to provide storage services for the computer host. [0003] As the core system of storage, the storage system undertakes the data of various business systems and needs to provide 7x24 hours of uninterrupted services. It is necessary to upgrade the microco...
