Problems solved by technology

[0004] However, when the storage array needs to be upgraded, it usually needs to be shut down for the upgrade, which will cause the storage array to be out of service due to the downtime. At the same time, after the upgrade, a certain period of test operation is required. I don’t know if the upgrade is successful and the storage array needs to be stopped.

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The method provided by the present invention can speed up the upgrade process of the storage array, and only upgrade the software modules that need to be upgraded, and if a failure occurs during the upgrade process and the upgrade fails, the present invention will quickly fall back to the upgraded version that was running before the upgrade. So that the business will not be interrupted, and the normal working state will be restored as soon as possible.

[0034] The technical solutions provided by this application include figure 1 process shown.

[0035] see figure 1 , figure 1 The flow chart of the method provided by the embodiment of the present invention.

[0036] Among them, in the description figure 1 Before the method process prov...

Abstract

The invention provides a method and device for avoiding service interruption of a storage array in the upgrading process. In the method and the device, when the storage array needs to be upgraded, only software modules which need to be upgraded are upgraded; meanwhile, if upgrading fails due to the fact that failures occur in the upgrading process, the software modules can rapidly go back to the upgrade version which runs before upgrading through the method and the device, and therefore services can not be interrupted, and the normal work state can be recovered as soon as possible.

Description

technical field [0001] The present application relates to storage technology, in particular to a method and device for avoiding service interruption of a storage array during an upgrade process. Background technique [0002] Storage arrays, which store data in computer systems, are generally required to provide extremely high reliability to ensure data security and stability. At the same time, storage arrays are also required to be able to provide uninterrupted data services. [0003] In order to achieve the high reliability and uninterrupted service required by the storage array, most of the current storage arrays adopt the design of dual control systems or multiple control systems. Under this design, when a software or hardware failure occurs in one of the control systems, the remaining The control system can immediately take over the control right, provide data application services to the outside world without affecting the user, and notify the system management to deal w...
