Problems solved by technology

For administrators, when there is no physical hardware alarm, multipath failover is not easy to be noticed by the administrator on the host side. If the fault is not repaired in time, it may lead to more serious consequences.

Embodiment 1

[0034] Such as figure 1 Shown, a kind of multi-path condition monitoring method comprises the following steps:

[0035] S1. Judging path failure by periodically querying multipath output information;

[0036] S2. Execute the path fault diagnosis and judgment process according to the storage type classification;

[0037] S3. Send the link fault point to the monitoring terminal.

Embodiment 2

[0039] Such as figure 2 Shown, a kind of multi-path condition monitoring method comprises the following steps:

[0040] S1. Set the interval time and execution authority of periodic query.

[0041] S2. Periodically query multipath output information, and determine that a path is faulty when it is detected that a faulty keyword exists in the state of a certain path in the multipath state information.

[0042] S3. Determine whether the storage type is IP storage, respectively test whether the communication between the storage service port, the storage management port, and the switch management port is normal, and determine the link failure point.

[0043] S4. Determine whether the storage type is FC storage, respectively test whether the communication between the storage optical port, the storage management port, and the fiber optic switch management port is normal, and determine the link failure point.

[0044] S5. Send the link fault point to the monitoring terminal.

Embodiment 3

[0046] A multipath state monitoring method, comprising the following steps:

[0047] S1. Install the multipath software, copy the script to the directory under the Linux system, and use chmod+x to add executable permissions to the script.

[0048] S2. Through the Crontab command under the Linux system, write an instruction specifying time or interval, so that the system automatically executes the script program according to the timing plan.

[0049] S3. The program automatically monitors the status of the multipath according to the timing plan. When the script detects the faulty keyword in the status of a certain path in the multipath status information, it will determine that the path is faulty, and then execute the fault down. diagnostic process.

[0050] S4. When the script program finds a multi-path transmission failure, first use the iscsiadm command to find whether there is link information of IP storage in the system under the Linux system. If the information of the IP...

Abstract

The present invention discloses a multi-path state monitoring method. The method comprises the following steps of: determining path faults through period query of multi-path output information; executing a path fault diagnosis determination flow in a classification mode according to a storage type; and sending link fault points to a monitoring terminal. The present invention further discloses a multi-path state monitoring device. The multi-path state monitoring method and device can automatically perform multi-path state scanning, and can achieve uniform monitoring for multi-type stored multi-path states with no need for consideration of the difference of the storage types so as to achieve simple and convenient monitoring and diagnosis for the multi-model stored link states.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to the storage based on the multipath function under the Linux system and the realization of the fault diagnosis function of the storage-to-host link abnormality. Background technique [0002] With the development of new technologies such as cloud computing and big data, people use more and more storage servers. The same data center computer room generally involves a variety of different types of storage servers, and each storage server is generally connected to the host. With multiple links, this involves the concept of multipath redundancy. Multipath redundant I / O (Multipath I / O) means that the server is connected to the storage device through multiple physical paths. Its main function is that when a physical path fails due to failure of the host HBA card, cable, switch, or RAID controller of the storage device, the server can transfer the I / O through this physical path ...
