Problems solved by technology

However, according to the solutions in the prior art, if the data center whose registration information has been deleted initiates a registration request and an arbitration request again, the arbitration server will save the registration information of the data center and judge the data based on the registered information of the data center saved by it. The center can take over the mainframe business. In this way, two data centers will take over the mainframe business at the same time, so that the externally provided mainframe business will be inconsistent.

Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] According to the device arbitration method and device of the embodiments of the present invention, the arbitration can be performed on the array of the active-active system or on the logical storage unit (Logic Unit Number, LUN) on the array, and can also be performed on other devices or units that need to be arbitrated. In the following, the embodiment of the present invention will be described in detail by taking an array as an example. The emb...

Abstract

Embodiments of the invention disclose a device arbitration method and device. The method comprises: a first storage device sends an arbitration request message to an arbitration server; according to the arbitration request message, registration information of the first storage device and the situation that a second storage device does not take over host services, the arbitration server sends an instruction message to the first storage device to instruct the first storage device to take over the host services and deletes the registration information of the second storage device. The first storage device sends a reservation request message to the arbitration server and instructs the arbitration server to prohibit the second storage device from registering. The method and the device can avoid the possible situation that data is out of sync because a plurality of devices take over the host services at the same time, and improve the fault tolerance, reliability and security of a dual active arbitration system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a device arbitration method and device. Background technique [0002] With the development of information technology, data processing is becoming more and more concentrated, and the requirements for data security are getting higher and higher. The active-active system is a computer disaster recovery (Disaster Recovery) solution that saves resources. One data center undertakes the business of users at the same time, and the two data centers back up each other and perform real-time backup. [0003] When the communication between the two data centers of the active-active system is disconnected, the two data centers will each send an arbitration request message to the arbitration server, requesting to take over the host business. The arbitration server saves the registration information of the two data centers. After the server determines that one of the data centers can take over ...
