Describe the Fault Locating Method based on the hard disk of raid card daily record according to the embodiment of the invention in detail below in conjunction with accompanying drawing 1-5.
As shown in Figure 1, based on the Fault Locating Method of the hard disk of raid card daily record, wherein, asynchronous real time propelling movement interface is set between disk array raid card and server according to an embodiment of the invention, and be provided with the asynchronous event processing engine in the server, this method may further comprise the steps:
Step S101, the raid cartoon is crossed asynchronous real time propelling movement interface with the asynchronous event processing engine of raid card daily record real time propelling movement to the server.
Particularly, all event informations that the raid card takes place have been recorded in the complete daily record of raid card, comprise the numbering of event in daily record, time of origin, information such as event description and event data.Adopt asynchronous mechanism to realize the real-time Communication for Power of server this locality and raid card controller, in case event occurs for the raid card, the raid card controller is in its storer in daily record storage time, utilize asynchronous event to push interface and be pushed to the asynchronous event processing engine that operates in the server, the asynchronous event processing engine is carried out analyzing and processing to event information.
Step S102, monitoring tool is analyzed the current state of hard disk, if the Logical Disk of hard disk is in degradation degraded state or the offline state that rolls off the production line, judges that then hard disk breaks down.
Particularly, the Logical Disk state of hard disk has optimal, and three kinds of states of degraded and offline reflect normal, degradation and the down status of current raid card logic dish respectively, and in other words, above-mentioned three kinds of states can be understood as corresponding normal and fault two states.Degraded or offline state occur when monitoring tool monitors Logical Disk, then decision logic dish corresponding physical dish breaks down.Wherein, monitoring tool is but is not limited to the MegaCli instrument.
Step S103, when judging that hard disk breaks down, the asynchronous event processing engine to the raid card daily record analyze to obtain and fall the relevant log information of dish, and with fall to coil relevant log information and push to the internal memory of server to generate the daily record of local raid card.Particularly, after the asynchronous event processing engine obtains the log information relevant with falling dish, processing is analyzed, filters and formatd to this log information relevant with falling dish, and will format the internal memory that log information after handling pushes to server, in order to generate the daily record of local raid card, convenient real-time inquiry and real time propelling movement when reaching zero influence to server performance, are accomplished obtaining in real time key message.
Step S104, monitoring tool grasp many transition logouts of the physical disks of disk in the daily record of local raid card, and obtain the end-state of hard disk according to many transition logouts.
Particularly, the transition state of transition logout hard disk comprises: normal condition is transitted towards malfunction, malfunction is transitted towards normal condition and malfunction is transitted towards abnormality.And the concrete step of the end-state of obtaining hard disk according to many transition logouts is: the time to many transition logouts is analyzed, and obtains a transition logout of final time, obtains the end-state of hard disk.
Step S105, monitoring tool is compared current state and the end-state of hard disk, if current state and the end-state of hard disk do not match, judges that then the physical disks of hard disk is fallen dish.Further, if the current state of hard disk and end-state coupling judge that then hard disk breaks down.
A flash is arranged on the raid card, and the various log when being used for the permanent storage operation can not lose during power down yet; Event in the raid card operational process comprises any situation of falling to coil that occurs, and corresponding state change all can be recorded among the flash.So utilize raid card stored log can cover hard disk failure very all sidedly.Then in above-mentioned example, for LSI type raid card, can utilize the MegaCli instrument to grasp raid card controller, the health parameters of physical disks and Logical Disk etc.For example, the Logical Disk state has optimal, and three kinds of states of degraded and offline reflect normal, degradation and the down status of current raid card logic dish respectively, and in other words, above-mentioned three kinds of states can be understood as the state of corresponding normal and fault.If degraded or offline state appear in Logical Disk, then can necessarily there be fault by decision logic dish corresponding physical dish.Accordingly, the media Error of physical disks, predictive failure, numerical value such as firmware state have reflected the running status of current physical disks, the firmware state online that reaches the standard grade, failure failed, unusual unconfigure_good, state values such as fault unconfigure_bad reflect the normal and abnormality of current physical disks respectively.In conjunction with the status information of Logical Disk and physical disks, can judge effectively whether the raid card is current moves normal and which piece Logical Disk has problem.
For the raid card that physics falls dish does not take place, above-mentioned detection means all can detect hard disk failure real-time and accurately.But when generation physics fell to coil, the raid card controller was no longer kicked out of array with this dish, causes falling the running state information of the faulty hard disk of dish not to be acquired in real time, also just can't navigate to the fault of this hard disk with above-mentioned means.Consider that the raid card controller can in time be recorded to event information in the daily record of raid card, comprise that physics falls to coil event information, can obtain the daily record of raid card and analyze, excavate the hard disk real-time running state information that to obtain, thereby realize generation physics is fallen the location of the faulty hard disk of dish.
Because all event informations that the raid card takes place have been recorded in the complete daily record of raid card, comprise the numbering of event in daily record, time of origin, event description, information such as event data, when server raid card event takes place when frequent, the log information amount is very big, and frequently reading daily record can influence server performance to internal memory.Be directed to this, adopt asynchronous mechanism to realize the real-time Communication for Power of server this locality and raid card controller, in case event occurs for the raid card, the raid card controller is stored in the event log in flash, utilize asynchronous event to push interface and be pushed to the asynchronous event processing engine that operates in the server, the asynchronous event processing engine is carried out the real-time information analysis, filters and format, the log information of format is stored in the server local hard drive, convenient real-time inquiry and data mining.Event asynchronous communication framework between raid card and the server has been realized the real time propelling movement of log information to this locality, when reaching zero influence to server performance, to obtaining in real time of key message.Asynchronous push is stored in the local daily record to the daily record increment of this locality, uses for fault location.It pushes synoptic diagram as shown in Figures 2 and 3.In conjunction with Fig. 2 and Fig. 3, when raid card when event occurs, the raid card reads the correlation parameter of event from its RAM, and on the one hand, raid card parameter information in its flash generates raid card log daily record; Simultaneously, on the other hand, the raid card pushes the interface propelling data to asynchronous event, and the asynchronous event processing engine of server receives and deal with data, and the data after will formaing are stored in server memory to generate the daily record of local raid card.
Event information type in the daily record of raid card has kind more than 200, and falling to coil relevant type with the location has 5 kinds, and wherein 2 class events of most critical are the status change information record of Logical Disk and physical disks.Status change information is recording the situation of change of hard disk running status, comprise by normal condition to malfunction, by malfunction to normal condition, by a kind of malfunction (unconfigure_bad) to another kind of abnormality (unconfigure_good) etc.Wherein, for example shown in Figure 4 about the set form that records of the event description (Event Description) of raid card logic dish and physical disks, be about a record of the state variation of physical disks in the daily record of raid card.
Every hard disk can have a lot of status change records in its cycle of operation, have only the current running state information of this piece hard disk of storage in the last item status change record.Event description record to this type of form is analyzed, obtain the final running status of every hard disk, thereby take place under the situation of current running status of hard disk that physics falls dish can't obtaining in real time, file by the event in the daily record of raid card, navigate to corresponding physical disks and fall dish, thereby improved failure checking cover ratio.
Fig. 5 is in accordance with another embodiment of the present invention based on the process flow diagram of the Fault Locating Method of the hard disk of raid card daily record.
