Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of specific examples, which are illustrative of the present invention and are not limited to the following embodiments.
As shown in fig. 1, the present invention provides a dual-port disc management method, which includes the following steps:
s1, monitoring whether input and output errors occur in the two ports in real time, and accumulating the count when the input and output errors occur;
s2, when the input and output error number of a port is more than that of another port, kicking the port out;
and S3, pulling back the kicked port when the input and output error numbers of the two ports are the same.
Preferably, when input and output occur at any port, an error alarm is sent out to prompt a user to pay attention to the condition of the hard disk port and plan in advance.
The method comprises the steps of firstly kicking a port and counting when IO errors such as transport error occur in a certain channel. The advantage of doing so is to let the IO go through a better channel and the alarm will prompt the user to pay attention to the status of the hard disk port and plan ahead. This method differs from other methods in that when the same problem occurs in the second channel, the port is no longer kicked, and only an error count is performed. Because the health conditions of the two channels are equivalent, the port kicked off before is pulled back, the two channels are used, when the abnormality occurs again, the error counts of the ports are different, the port with larger error count is kicked off, and the use is relatively less in error. The ports are used according to the sequence, so that the port with the error can temporarily stop IO processing, and the errors are prevented from accumulating in a short time or even being broken down and cannot be used.
Of course, there is no limitation such as alternate use, and when the error accumulates to the threshold, the backup disk should be started or other processing should be done. Preferably, the method further comprises the following steps on the basis of the steps S1-S3.
S4, when the input/output error number of any port reaches a first threshold value, detecting whether a backup disc exists;
s5, if a backup disc exists, the current double-port disc is off-line, and the backup disc is on-line;
s6, if there is no backup disc, the method of steps S1-S3 is adopted to use the current dual-port disc.
If there is no backup disc, the error continues to occur when the current dual-port disc is used, and when the error count is too large, the following step S7 should be executed:
and S7, if the input/output error number of any port reaches a second threshold value, taking the current dual-port disk off line. Wherein the second threshold is greater than the first threshold.
Preferably, in step S5, when the number of input/output errors of any port reaches the first threshold value, there is a backup disk, and the current dual-port disk is taken off-line, a first alarm is issued. And S6, when the input/output error number of any port reaches a first threshold value and no backup disk exists, continuing to use the current dual-port disk by adopting the method of the steps S1-S3, and sending a second alarm. And step S7, when the input/output error number of any port reaches a second threshold value and the current dual-port disk is offline, sending a third alarm.
When the error is accumulated to the threshold value, if a backup disk exists, the double ports of the disk with the error are directly offline, the data safety is ensured, and the alarm is given to prompt a user to replace the hard disk; if no backup disc exists, the double-port disc is off-line due to disc kicking at the moment, data cannot be processed normally, so disc kicking is not performed temporarily, the logic of alternately kicking ports before use is continued, a warning is given to prompt a user to change the disc, and disc kicking is performed without redundancy if a counting threshold value with serious errors is reached.
In the following, a specific implementation manner is provided to further explain the present invention based on the principle of the present invention by combining the above methods. As shown in fig. 2, the specific implementation method includes the following steps.
S101, monitoring two ports in real time;
s102, judging whether an input/output error occurs or not;
s103, if an input/output error occurs, carrying out input/output error accumulated counting on a corresponding port, simultaneously sending out an error alarm, and entering the next step; otherwise, continuing to execute the step S101;
s104, judging whether the input/output error number of the port with the input/output error currently reaches a second threshold value;
s105, if the result is not reached, the next step is carried out; if so, taking the current double-port disc off line;
s106, judging whether the input/output error number of the port with the input/output error currently reaches a first threshold value;
s107, if not, entering the next step; if yes, go to step S111;

s110, if not, pulling back the kicked port, and continuing to execute the step S101;

s112, if yes, the current double-port disk is offline, and a backup disk is online; if not, the process continues to step S101.
