Detailed Description
The core of the invention is to provide an online detection method of storage equipment, which does not need to install valuable management monitoring service software, realizes the availability check of each storage node equipment by performing ping communication on the ip of each equipment to be detected in the storage environment, and can greatly reduce the operation and maintenance cost while effectively performing online detection on each equipment; the other core of the invention is to provide a storage device on-line detection device, a device and a readable storage medium.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an online detection method for a storage device according to an embodiment of the present invention; the method mainly comprises the following steps:
and step s110, recording the device ip to be detected, and generating the ip information of the device to be detected.
And recording all the to-be-detected devices ip in all the current storage environments in the to-be-detected device ip information to generate the to-be-detected device ip information, wherein the to-be-detected device ip information can be stored in a list or a document and the like, and is not limited herein. The ip information of the equipment to be detected can be updated and edited, when a new storage node is added into the current storage environment or a certain storage node in the current environment is removed, the ip of the equipment to be detected in the ip information of the equipment to be detected can be directly edited (the ip of the equipment is added or deleted), and the overall detection management of the storage environment is facilitated.
And step s120, sending ping communication packets to each device to be detected ip in the device to be detected ip information.
And step s130, receiving ping communication return information.
The ping communication utilizes the uniqueness of the ip address of a machine on a network to send a data packet to a target ip address, then requires the opposite side to return a data packet with the same size to determine whether two devices are connected and communicated, and carries out ping communication on the ip of a device to be detected, the end-to-end communication detection of each storage node device in a storage environment can be completed by one device, the ping communication packet sent to the ip of each device to be detected needs to ensure the normal operation of the current device sending the ping communication packet, if a certain ip communication fails, the returned ping communication packet shows that the communication packet cannot be read normally, and as a sending end is normal, the receiving end is not on line, the availability check of each storage node device can be realized by carrying out ping communication on the ip of each device to be detected, and the remote management of the devices can be completed.
The ping communication return information comprises normal receiving times, namely the times of normal received, and the online condition of the equipment can be determined according to the normal receiving times. If the ping communication packet is sent once and read once normally, the communication is normal; if the ping communication packet is sent once and the reading is normally carried out for zero times, the network signal is abnormal.
Because a certain influence may be generated on a detection result by single ping communication when a network signal is unstable, in order to avoid the influence of interference of other factors on ping communication return information and improve the accuracy of equipment availability detection, preferably, a plurality of ping communication packets can be sent to each equipment to be detected according to ip information of the equipment to be detected. The sending of a plurality of ping communication packets of one device can adopt continuous sending, namely a plurality of ping communication packets are continuously sent to one device and then a plurality of ping communication packets are continuously sent to another device; and the ping communication packets can be sent circularly, namely after one ping communication packet is sent to one device, the ping communication packet is continuously sent to the other device, after all the devices go through one cycle, the ping communication packets are sent to the devices to be detected in the ip information of the devices to be detected one by one again until the preset number of ping communication packets are sent to each device to be detected, and then the process is terminated.
When each storage device is subjected to ping communication for a plurality of times, the corresponding device online condition determining mode can also be subjected to adaptive adjustment, and the determining rule is not limited specifically. For example, when 5 ping connections are made to each storage device, it may be determined that the storage device is normal when the 5 ping connections are successful; if the failure occurs for 5 times, the storage device can be determined to be offline; if the normal times are between 0 and 5 times, the connection can be determined to be unstable; further, it is also possible to provide: when the connection is successful for 3 times or more, the storage device is normally online, and when the connection is successful for 3 times or less, the storage device is abnormal, and the like.
Various parameters can also be added for the ping communication to be used in a matched manner, so that the performance of each parameter of the receiving end can be tested, which can be referred to in the prior art specifically and is not described herein again.
And step s140, determining the online condition of each device to be detected according to the normal receiving times of each device to be detected.
The above description is about the process of performing single online detection on the storage device, and for performing real-time continuous detection on each operating state of each storage device, it is preferable that a ping communication packet is sent to each device to be detected ip in the information of the device to be detected ip at preset intervals, so as to continuously monitor each storage device in the storage environment, so as to timely process the abnormal storage device.
Based on the introduction, the storage device online detection method disclosed in the embodiment of the present invention can obtain all devices to be detected in a storage environment by recording ip of the devices to be detected in the storage environment, and perform ping communication on the ip of the devices to be detected, so that end-to-end communication detection of each storage node device in the storage environment can be completed in one device, availability check of each storage node device is realized, and remote management of the device is completed.
Based on the above embodiment, after the online status of each device in the storage environment is obtained, to output the prompt information for the detected online status of the current storage device, so that the user can timely know the current device status and perform corresponding processing, preferably, after the online status of each device to be detected is determined, the online prompt information of the storage device can be output according to the online status of each device to be detected.
Different detection results are generated according to different conditions of the storage device, including situations such as normal communication, no connection, and unstable signals. Different detection results correspond to different processing modes, for example, when the storage device cannot be connected, a worker needs to immediately overhaul the device so as to avoid processing a normal service request.
In order to facilitate a user to obtain key information when checking the prompt information, the online prompt information can be output and set according to the online condition of each device to be checked. For example, when the communication is normal, a normal white word is set; when the device cannot be connected, the setting is red characters, etc., and only the font color setting is described here, and other setting modes including setting font size, format, jitter, etc. are not described herein again.
In order to deepen understanding of the data storage method provided by the invention, the whole online detection process is described by taking the case of circularly sending 5 times of ping communication packets to each device when the device operates in the Shell environment, and other implementation modes of the storage device online detection method provided by the invention can refer to the description of the embodiment.
