Embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar assembly or the assembly with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the present invention, and can not be interpreted as limitation of the present invention.
Please refer to Fig. 2 below, this figure is the recognition system structure calcspar of JBOD of the single-wire cascading topological structure of the embodiment of the invention.Here, be that example is made an explanation to JBOD recognition system of the present invention with machine and JBOD with dual controller, and can be with reference to shown in Figure 1 about the JBOD single-wire cascading topological structure of this dual controller.
It is pointed out that this embodiment is illustrating of the principle of the invention only, is not used in restriction and invention.The content that obvious those skilled in the art can describe by present embodiment easily is applied to this invention under the multi-controller.
As shown in Figure 2, in host computer system with dual controller SDA01 and SDA02, correspondence includes hardware management module 12 and 22, Configuration Manager 14 and 24, synchronization module 16 and 26, reaches identification module 20 and 30 under each controller, has identical framework on the different controllers of this pair control.Hardware management module 12 is used for obtaining each JBOD of corresponding connection with console controller SDA01 and goes up the hardware configuration information of hard disk.Certainly, need be provided with here insert one on each JBOD at least can be by the disk of system identification, thereby can obtain to be identified the hardware configuration information of disk.In addition, each JBOD goes up each corresponding controller, controller C11 and the controller C21 of C12, JBOD2 and controller C31 and the C32 of C22 and JBOD3 of the JBOD1 that is connected with SDA01, SDA02 correspondence respectively for example shown in Figure 1, their Serial Attached SCSI (SAS) (SAS) addresses separately are unique in system.
In an embodiment, the key message of JBOD has: WWN: global title (World Wide Name), and the SAS address of last each controller of JBOD can also comprise Level:1,2 ..., represent the order of connection of each JBOD.The key message of hard disk has SN:Serial Number, and the sequence number of hard disk has uniqueness, can also comprise Slot:1, and 2 ..., represent the slot position of hard disk on corresponding JBOD.
The key message that synchronization module 16/26 is used for the hard disk that will obtain under the current controller system and JBOD is written to another corresponding controller database 28/18 synchronously, finishes two communications between the controller.In order to realize the same identification of JBOD under the dual controller, need to keep on each controller database information synchronously in real time.
When another controller is found the hard disk sequence number of the hardware configuration information that current controller synchronization module writes, when promptly finding the hard disk of this sequence number correspondence, synchronization module 16/26 writes hard disk sequence number, its corresponding JBOD identifier and the SAS address of current controller in the hardware configuration information of this another controller.
In the hardware configuration information of another controller, had the hard disk sequence number of the hardware configuration information of described other controller, synchronization module 16/26 also uses unique JBOD identifier corresponding with the hard disk sequence number in the hardware configuration information of current controller, adds its corresponding SAS address information under its JBOD information.
When JBOD is that synchronization module adds this JBOD corresponding hardware configuration information and JBOD identifier in each controller hardware configuration information of main frame to when newly inserting in the single-wire cascading topological structure.When removing JBOD from single-wire cascading topological structure, synchronization module is deleted JBOD corresponding hardware configuration information and JBOD identifier from the hardware configuration information of each controller of main frame.
By above-mentioned principle and recognition system structure of under dual controller, carrying out the JBOD same identification, those of ordinary skill in the art obviously as can be known, with the same manner, can easily the key message that obtains when previous controller be written to synchronously in other any controller under the multi-controller environment, the relevant information that other each controller obtains when starting also can share in any one controller of current structure synchronously.
Below in conjunction with Fig. 3, the recognition methods of the JBOD of the single-wire cascading topological structure of the embodiment of the invention is described as follows.
At first, obtain the hardware configuration information (step 102) of corresponding JBOD that connects of the current controller of main frame and last hard disk thereof; Hardware configuration information for example comprises the SAS address of the current controller of main frame and unique sequence number of hard disk.Then, hardware configuration information is synchronized in each controller of main frame (step 104).This recognition methods can also comprise whether the hard disk sequence number of judging hardware configuration information is present in the step in the existing hardware configuration information of the current controller of main frame, and when the hard disk sequence number did not exist in the existing hardware configuration information, promptly the JBOD for hard disk of finding first and place thereof generated unique JBOD identifier.At last, according to the hardware configuration information after synchronous, carry out of the identification (step 106) of a plurality of controllers of main frame to same JBOD in the single-wire cascading topological structure.
Below in conjunction with Fig. 4 the synchronizing step of JBOD recognition methods of the present invention is made description, Fig. 4 is the synchronizing step process flow diagram of recognition methods of the JBOD of embodiment of the invention single-wire cascading topological structure.
At first, compare the hardware configuration information of the current controller of main frame and the hardware configuration information (step 202) of other controller; Then, judge the hard disk sequence number (step 204) of the hardware configuration information that whether has current controller in other controller.Here,, represent that then the hard disk of this sequence number correspondence does not exist under this other controller, then finish if there is not the hard disk sequence number of the hardware configuration information of current controller.If exist, then hard disk sequence number, its corresponding JBOD identifier and the SAS address with current controller correspondence writes in other controller (step 206), and promptly corresponding JBOD and the hard disk that connects of each controller is increased in the configuration information of other console controller at the corresponding key message of current controller.And, because each console controller connects with the different controllers of same JBOD, the JBOD WWN that is obtained, the SAS address that is the JBOD controller is different, so JBOD unique identifier corresponding in the hardware configuration information of the current controller of needs use with the hard disk sequence number, generate the SAS address of the controller correspondence of each JBOD under other console controller, and add in other controller corresponding hardware configuration information (step 208).
Below, be specific embodiment with the JBOD of single-wire cascading topological structure under the dual controller of Fig. 1, JBOD recognition methods under the multi-controller of the present invention is described in detail as follows.
For example, when start-up control device SDA01, controller SDA01 detects its corresponding 3 JBOD (JBOD1, JBOD2 and JBOD3 that connect, and have one above each at least and can discern disk), therefore obtain their hardware configuration information, and generate this 3 JBOD_ID that JBOD is unique, and with information stores in database.For example, obtaining JBOD1, JBOD2 and JBOD3, to go up the configuration information of corresponding hard disk as shown in table 1 below:
Table 1
| ??SN | ??Controller | ??JBOD_ID | ??Slot |
| ??6PT17DP1 | ??SDA01 | ??35b730ac-f78d-4164-b127-b5595f697d7a | ??1 |

| ??6PT17VYW | ??SDA01 | ??f7a6288f-ffef-4e5d-874b-ca74fdcb6247 | ??1 |
Here, Controller represents to connect the system banner of the console controller of corresponding JBOD; Status represents connection status, and 0 for disconnecting, and 1 for connecting; JBOD_ID is the unique identification of JBOD.
The correspondence configuration of JBOD1, JBOD2 and JBOD3 is as shown in table 2:
Table 2
| ??WWN | ??Level | ??Status | ??Controller | ??JBOD_ID |

Then, during start-up control device SDA02, can be in its database with above configuration synchronization.Find on the SDA02 3 JBOD with and on Hard Disk, at first also obtain the information of this JBOD and hard disk thereof, then with database in information compare.If hard disk does not exist in the configuration, just generate the JBOD identifier of its place JBOD, as the unique identification of JBOD, write local database together with the key message of hard disk and JBOD.In this embodiment, in the database of controller SDA02, be found to be the hard disk sequence number of 6PT17DP1, the disk of this sequence number correspondence exists on controller SDA01, therefore use controller SDA01 to go up the identical JBOD_ID of this hard disk correspondence, in the JBOD of controller SDA02 table, add new JBOD record, i.e. the SAS address of the controller of each JBOD correspondence under master control controller SDA02 simultaneously.
At this moment, hard disk configuration information under the console controller SDA02 and JBOD configuration information are respectively shown in table 3 and table 4.
