Problems solved by technology
[0003]Due to all operations of volume mapping, the time consumption of creating volumes, creating targets, binding hosts, binding IQNs, mapping volumes, logging in to hosts, and scanning hosts will affect The wait time for the logical volume to be visible on the host. However, there is no fixed formula for how long to wait to see the logical volume. At present, it is generally checked every once in a while until it is visible
[0004] It can be seen that there is blindness in the process of waiting for the logical volume to be visible

The invention discloses a prediction method for volume visible waiting time. The prediction method comprises the following steps: obtaining the time length consumed by each operation when a logical volume is mapped and constructing a to-be-predicted sample; multiplying the to-be-predicted sample by a reward and punishment factor, and adding a preset mean value to obtain a predicted waiting time length; comparing the predicted waiting time length with the current waiting time length; and in response to the fact that the current waiting time length is greater than the predicted waiting time length, determining a fault occurrence probability according to the current waiting time length and performing feedback. The invention further discloses a system, computer equipment and a readable storagemedium. According to the scheme provided by the invention, the visible waiting duration of the logical volume can be predicted according to the duration of the mapping logical volume. And secondly, in the waiting process, dynamically prompting the remaining waiting duration, and if the consumed time exceeds the predicted total duration, the probability of a fault is estimated. Through the method,the user does not need to wait blindly any more, and knows the operation dynamic state in real time.
Description
technical field [0001] The present invention relates to the field of prediction, and in particular to a method, system, device and storage medium for predicting volume visible waiting time. Background technique [0002] After the storage system is connected to the host, volumes can be mapped to the host to provide storage space for the host. The steps of volume mapping include creating a volume, creating a target, binding the host, binding the IQN, mapping the volume, logging in to the host, scanning the host, and waiting for a while to see the logical volume on the host. [0003] Due to all operations of volume mapping, the time spent on creating volumes, creating targets, binding hosts, binding IQNs, mapping volumes, logging in to hosts, and scanning hosts will affect the waiting time for logical volumes to be visible on the host. However, how long does the wait It takes time to see the logical volume. There is no fixed formula. At present, it is generally checked every o...
