Problems solved by technology

[0004] However, the existing disaster recovery management software only judges whether there is a failure based on the status data reported by the three sites respectively. This mode is likely to cause misjudgment. The management software misjudged that site A was faulty because it could not obtain the data of site A, and performed a failover
It can be seen that once a diagnosis error occurs, it will cause a faulty switchover of disaster recovery, which will affect the normal processing of business and reduce the efficiency of disaster recovery

Embodiment 1

[0056] like figure 1 As shown, this embodiment provides a ring-shaped fault diagnosis method for two places and three centers, including:

[0057] 1. Regularly receive the data of the three sites through the disaster recovery management software.

[0058] 2. Determine whether the data of site A is received normally. If the data of site A is received abnormally, collect the data of site A through other sites and store it in the array data[0].

[0059] As an example, if the data reception at site A is abnormal, first obtain the data at site A through the peer end of the remote replication relationship whose connection to site A is enabled and feed it back to the disaster recovery management software, and then use the disaster recovery management software to judge whether it is received Feedback site A data.

[0060] If no feedback is possible, first obtain the data of site A through the peer end of the remote replication relationship whose connection to site A is in the standb...

Embodiment 2

[0075] Based on the first embodiment, the present invention also discloses a fault diagnosis method for ring-shaped two places and three centers.

[0076] Among them, the data transmission relationship between the ring two sites and three centers is as follows: the synchronous remote replication relationship between site A and site B, the asynchronous remote replication relationship RCy between site B and site C, and the asynchronous remote replication relationship between site A and site C The remote replication relation RCz is standby.

[0077] The present invention is specifically as follows:

[0078] An example is used when the disaster recovery management software cannot receive the status information of site A. If the disaster recovery software does not receive the status information of site A within the required time, the disaster recovery software will send a message to site B to notify site B to send the status information of site A. When site B obtains the data of ...

Embodiment 3

[0082] Based on Example 1, such as figure 2 As shown, the present invention also discloses a circular fault diagnosis system with two locations and three centers, including: an initialization unit 1, a timing acquisition unit 2, a data reception determination unit 3, a first abnormality processing unit 4, and a second abnormality processing unit 5 , a third exception processing unit 6 , a status data acquisition unit 7 , a status data comparison unit 8 and a fault processing unit 9 .

[0083] The initialization unit 1 is configured to initialize the ring 3DC strategy, and initialize the fault count n to 0.

[0084] The timing collection unit 2 is used to regularly receive the data of the three sites through the disaster recovery management software.

[0085] The data receiving judging unit 3 is used to judge whether the data of the A station, the B station and the C station are received normally.

[0086] The first exception processing unit 4 is configured to collect the da...

Abstract

The invention provides an annular two-place three-center fault diagnosis method, an annular two-place three-center fault diagnosis system and an annular two-place three-center fault diagnosis device. The sequence of acquiring the state information of the faulty site through the other sites is as follows: firstly, acquiring the state information of the faulty site through the site where the started remote replication relation opposite end is located, and if the state information can be normally acquired and fed back to the disaster recovery management software, considering that the information of the faulty site is successfully acquired through the other sites; if the state information of the fault site is not acquired, acquiring the state information of the fault site through the backup site where the opposite end of the remote relation is located, and if the state information can be normally acquired and fed back to the disaster recovery management software, considering that the information of the fault site acquired through other sites is successfully acquired; and if the information is not acquired for two times, the fault site is considered to fail really. According to the method, the false fault judgment rate of the annular two-place three-center is reduced, false fault switching processing is reduced, and then the disaster recovery service processing efficiency of the annular 3DC is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically relates to a fault diagnosis method, system and device for ring-shaped two places and three centers. Background technique [0002] In recent years, in order to ensure the continuity of the system work, a three data center in two sites (3dc) disaster recovery solution consisting of a production data center, an intra-city disaster recovery data center and a remote disaster recovery data center has been developed. Gradually recognized and valued by the industry. The existing circular two-site three-center (circular 3DC) mainly realizes the unified disaster recovery management of the three data centers through third-party disaster recovery management software. The disaster recovery management software can display the physical topology and business logic topology of the ring-shaped two-site three-center disaster recovery solution, and supports one-click disaster recove...
