Problems solved by technology

If a single disk is configured as RAID0, the logical disk may disappear after a physical disk failure, and the monitoring program cannot locate the failed physical disk.
For other levels or types of RAID arrays, the monitoring program cannot detect disk failures and / or effective failure information in a timely manner, which brings inconvenience to troubleshooting

Abstract

The invention provides a magnetic disk state transition detection method and device based on an asynchronous communication mechanism. The method includes the following steps of registering an event and a callback function of a redundant array of inexpensive disks (RAID) card; acquiring data of the event by using the callback function; filtering the data of the event to judge whether at least one preset field exists, and judging that state transition occurs to a magnetic disk if at least one preset field exists; and analyzing the data of the event to acquire positioning information of the magnetic disk, and accordingly acquiring the position of the magnetic disk which state transition occurs to. By means of the magnetic disk state transition detection method based on the asynchronous communication mechanism, state changes and other fault errors of a lower magnetic disc of the RAID card can be dynamically and real-timely monitored, problems can be processed at the first time, efficiencies can be improved, and risks of data damage and system downing can be reduced.

Description

technical field [0001] The invention relates to the technical field of information storage, in particular to a disk state transition detection method and device based on an asynchronous communication mechanism. Background technique [0002] If the disk is faulty, the RAID card will try to set the disk to the corresponding state mode, such as setting the physical disk from online to offline, and setting the logical disk from optimal to degrade, but the RAID (RedundantArraysofInexpensiveDisks, disk array) card will not set these The information is reported in real time, and the monitoring program must actively read the log of the RAID card to confirm whether a fault has occurred. [0003] In the prior art, relevant information about a faulty disk is determined by periodically checking the status of each disk of the RAID card, or checking an existing event record in the RAID card. For example, the time interval of t is set, and an active acquisition process is performed every ...
