Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification.
The application provides a hard disk state synchronization method, which is applied to a management controller of a server, as shown in fig. 1, and comprises the following steps:
s100, the state message interaction is carried out with the management controller of the opposite terminal server through the connected switching equipment.
A hard disk management system, as shown in fig. 2, comprising: at least two servers and storage devices, for example, include server 1 and server 2, wherein server 2 may be referred to as the peer server of server 1. Of course, the number of servers is not limited to two, and the present embodiment will be described by taking two as an example.
The servers 1, 2 include management controllers 10, 20 and memory control cards 11, 21. The storage device 3 comprises an expansion board 30 provided with an expansion controller 300 and a number of hard disks 31n, and a plurality of ports may be provided in the expansion board 30, which are respectively connected to the storage control cards 11, 21 of at least two servers (in this case, servers 1, 2), the management controllers 10, 20 in the servers 1, 2 being connected to the expansion controller 300 via the storage control cards 11, 21, and the management controllers of the at least two servers being connected via the switching device 4 and to the management device 5. According to the structure, a plurality of servers can be connected to the expansion board of one storage device through the storage control card of the servers, so that the connection between a plurality of management controllers and the hard disk of the storage device is realized.
The management controller may be a BMC, or may be another chip for implementing component status monitoring, which is not limited herein. The memory control cards 11, 21 may be HBA (Host Bus Adapter) cards or RAID (redundant array of independent disks ) cards, or the like. The management device 5 may be a personal computer or another server, and the management device 5 may access at least two servers by means of a direct connection or a network connection.
Between the management controllers 10, 20 of the two servers 1, 2, the active management controller and the standby management controller can be performed by exchanging the option report messages. The election message may be interacted based on the switching device 4, may be a two-layer message, and carries an election parameter for election such as a MAC (media access control ) address of the management controller 10, 20, and based on the election parameter and a preconfigured election policy, for example, a management controller with a minimum or maximum MAC address is selected from the management controllers 10, 20 as a primary management controller, and other management controllers are used as standby management controllers, and the primary management controller and the standby management controller may be used as roles set by the management controllers. In the present embodiment, the management controller 10 in the server 1 may be used as a primary management controller, and the management controller 20 in the server 2 may be used as a backup management controller. Of course, it should be noted that, instead of the interaction of the selection report, the role rotation sequence of the management controller may be directly defined according to the setting of the management device 5, or other information may be interacted as an election parameter, which is not limited herein.
After the servers 1, 2 are started and the roles of the management controllers are determined based on the election or setting, monitoring of the hard disk 31n deployed in the storage device 3 may be started. In this case, the main management controller may monitor the hard disk 31n and synchronize the status information of each hard disk 31n with the standby management controller after acquiring the status information, or the main management controller and the standby management controller may monitor part of the hard disk 31n and synchronize the status information with each other.
When synchronization is performed, the management controllers 10 and 20 may send status messages to each other, where the status messages carry status information of the managed hard disk in the storage device 3. The working state of the other party can be determined by the status messages between the management controllers 10 and 20, for example, the status messages can be sent between the management controllers 10 and 20 in a period of 10ms, and if the status messages are not received in 3 periods, the management controller of the opposite end server is considered to be faulty.
S101, if the state message sent by the management controller of the opposite terminal server is not received within a preset time interval and the state message is configured as a standby management controller, sending an alarm message to the server and the management device connected with the opposite terminal server, and sending a switching message to the expansion controller in the storage device.
The time interval mentioned here may be considered as the product of the period of sending the status message and the set number of periods, for example, 3×10ms, i.e. at a time interval of 30ms, and of course, a period may be set, i.e. it is determined that the management controller fails, and the configuration is performed according to specific requirements, which is not limited herein.
In order to monitor the status of the hard disk 31n in the storage device 3, a management instruction issued by the management device 5 may be received, where the management instruction may be used to set a hard disk that needs to be managed by the management controller, and may be a hard disk identifier that carries the hard disk that needs to be managed. After receiving the management command, the master management controller 10 may generate a partition request (that is, a hard disk to be managed, which is carried in the management command) according to the management command, and send the partition request to the storage device 3. After the expansion controller 300 of the storage device 3 receives the division request, a domain (Zone) may be divided, a hard disk identifier carried in the division request is added to the divided domain, and a first correspondence relationship among the domain, the managed hard disk, and the management controller is bound. By binding, the expansion controller 300 may determine an address or an identification that can monitor the managed hard disk, so that the expansion controller 300 can send the collected state information of the managed hard disk to the management controller.
Thereafter, the expansion controller 300 may periodically transmit the detected state information of the hard disk to the main management controller 10 for recording based on the first correspondence relationship, or the main management controller 10 may periodically transmit a detection request to the expansion controller 300 so that the expansion controller 300 feeds back the state information to the main management controller 10.
In this process, the active management controller 10 may send the acquired status information to the standby management controller 20 through a status message to synchronize the recorded status information of the managed hard disk between the active management controller 10 and the standby management controller 20.
If the standby management controller 20 does not receive the status message of the active management controller 10 within the time interval, it can be considered that the active management controller 10 is malfunctioning. At this time, the standby management controller 20 may send an alarm message to the management device 5 through the switching device 4 to notify that there may be a failure of the active management controller 10 to which the management device 5 is connected. At this time, the standby management controller 20 may actively transmit a handover message to the expansion controller 300 or transmit a handover message to the expansion controller 300 based on an instruction issued by the management device 5.
The switching message is used for notifying the expansion controller to modify the established first corresponding relation between the management controller of the opposite-end server and the managed hard disk into a second corresponding relation between the management controller of the expansion controller and the managed hard disk.
Specifically, the switching message may carry information such as a hard disk identifier of the managed hard disk sent by the master management controller 10. If the standby management controller 20 determines that the primary management controller 10 fails, a handover message is sent to the expansion controller 300. After the extension controller 300 receives the handover message, it may be determined that the message is a handover message sent by the standby management controller 20 and triggered to be modified based on information such as a message type. The expansion controller 300 analyzes the hard disk identifier from the switching message, divides the managed hard disk monitored by the original and main management controller 10 into another domain, and establishes a second corresponding relationship between the domain and the standby management controller 20, so that the standby management controller 20 can monitor the state information of the managed hard disk. The message of interaction between the management controller and the storage device 3, such as the switching message and the dividing request, may be realized based on the existing protocol between the management controller and the expansion controller and the hard disk, and for the switching message, a message type field may be independently agreed in the current protocol to enable the expansion controller to determine the function of the switching message, or the message type of the dividing request may be adopted to realize, which is not limited.
S102, based on the second corresponding relation, acquiring state information of the managed hard disk, and determining the running state of the managed hard disk through the state information.
Thereafter, the standby management controller 20 may actively request the expansion controller 300 for the status information of the managed hard disk based on the second correspondence, or passively receive the status information transmitted from the expansion controller 300 to the standby management controller 20.
Note that the first correspondence and the second correspondence may be recorded in a table maintained in the expansion controller 300, for example, a domain permission table (Zone Permission Table) may be maintained in the expansion controller 300, in which information such as a domain, a managed hard disk, and a port through which the management controller accesses the expansion controller 300 may be recorded, so as to record the correspondence between the management controller and the managed hard disk.
Through the steps, the main-standby relation can be formed between the storage device 3 and the management controllers 10 and 20 of the plurality of servers 1 and 2, the fault of the main management controller 10 is determined based on the state messages interacted between the management controllers, and the switching message is sent to the expansion controller 300 connected with the main management controller 10 and the standby management controller 20, so that the expansion controller 300 performs main-standby switching, and the subsequent state information of the managed hard disk is sent to the standby management controller 20 for monitoring, thereby avoiding the problem that the managed hard disk cannot be monitored when the management controller fails for one storage device, and improving the reliability of management and maintenance of the storage system.
Optionally, before the interaction of the status message with the management controller of the peer server through the connected switching device in step S100, the method further includes:
and S103, after the server is electrified, the server interacts with the management controller of the opposite-end server to select messages.
S104, determining the roles of the user according to the election parameters and a preset election strategy.
Wherein, the election message carries election parameters. The election parameter may be, without limitation, the MAC address of the management controller, the device identification of the server, and other information that may be used for identification. The election parameter can be used for electing one active management controller from a plurality of management controllers under the condition that the election parameter can be used for sequencing.
The election policy may be to determine, based on election parameters, a management controller corresponding to a maximum value or a minimum value in the election parameters as a primary management controller, and other management controllers as standby management controllers.
And S105, if the role of the expansion controller is the primary management controller, sending a division request to the expansion controller according to a management instruction issued by the management device so that the expansion controller establishes a first corresponding relation between the primary management controller and the managed hard disk in the storage device.
S106, receiving and recording the state information fed back by the managed hard disk.
When the management controller determines that the management controller is the main management controller, a division request can be sent to the expansion controller according to a management instruction issued by the management device, and a first corresponding relation is established, so that the main management controller monitors the selected hard disk.
Further, in step S100, after the interaction of the status message with the management controller of the peer server through the connected switching device, the method further includes:
and S107, if the state message sent by the management controller of the opposite terminal server is received within a preset time interval and the self role is the standby management controller, the state information of the managed hard disk managed by the management controller of the opposite terminal server is recorded.
After the main management controller receives the state information of the managed hard disk, the state information of the managed hard disk can be obtained according to the first corresponding relation to record, and the received information such as the hard disk identification and the state information of the managed hard disk is sent to the standby management controller to synchronously record.

Here, in the case shown in fig. 5, the server 1 and the server 2 may be connected to the plurality of storage devices 3A, 3B, and 3C, respectively, and the worker may cause the server 1 and the server 2 to manage the hard disk in one or more of the storage devices, respectively, according to actual needs, and may take over by another server in the case of a failure of one server, and of course, the number of servers is not limited to two.
It should be noted that, at the same time, one storage device can only be managed by one server, and the primary storage device may not be distinguished, i.e., the storage device managed by one server is configured, then the management controller in this server may be regarded as the primary management controller, and the other server may be regarded as the standby management controller. The opposite configuration may be made for another storage device, for example, the management controller 10 of the server 1 monitors the hard disk of the storage device 3A, and the management controller 20 of the server 2 monitors the hard disk of the storage devices 3B, 3C. It should be noted that, because the storage devices corresponding to the servers are different, there is no case that the active management controller works and the standby management controller stands by, because the storage devices corresponding to the active management controller and the standby management controller are different, the active management controller and the standby management controller need to be in a working state respectively in the same time period, and the state information corresponding to the different storage devices, that is, the management controller 10 of the server 1 needs to send the state information corresponding to the hard disk of the storage device 3A to the management controller 20 of the server 2, and the management controller 20 of the server 2 sends the state information corresponding to the hard disk of the storage device 3B and 3C to the management controller 10 of the server 1.
Then, it is assumed that, when the management controller 10 of the server 1 fails, the management controller 20 of the server 2 may take over the hard disk managed by the storage device 3A, so as to achieve synchronization for different storage devices among different servers in the storage system.
The technical scheme provided by the embodiment of the specification can comprise the following beneficial effects:
in the embodiment of the present disclosure, the management controller of the server is divided into a primary management controller and a standby management controller, and manages a plurality of hard disks through the same expansion controller, and the synchronization of the state information of the managed hard disk is implemented through the interaction of the state messages between the primary management controller and the standby management controller, and in a preset time interval, if the standby management controller does not receive the state message sent by the primary management controller, the hard disk managed by the primary management controller is taken over, so that the problem that the running state of the hard disk cannot be obtained when the management controller or the storage control card fails in the case that the single management controller manages the hard disk is avoided, and the reliability of management and maintenance of the storage system is improved.
It is to be understood that the present description is not limited to the precise arrangements and instrumentalities shown in the drawings, which have been described above, and that various modifications and changes may be made without departing from the scope thereof.
The foregoing description of the preferred embodiments is provided for the purpose of illustration only, and is not intended to limit the scope of the disclosure, since any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the disclosure are intended to be included within the scope of the disclosure.
