Effect of the present invention and manner of execution thereof specify in following preferred embodiment.Yet notion of the present invention also can be used for other scopes.Following listed examples only is used to the object of the invention and manner of execution are described, is not in order to limit its scope.
The upgrade method of the storage area network equipment of multi-controller is used to test the system architecture that possesses dual controller and shared single storage device.Fig. 1 is the sketch map of the system architecture that possesses dual controller and shared single storage device of preferred embodiment of the present invention.The so-called double-controller system of the present invention, can be considered is the distributed system that the computer with two tool basic operation abilities links, however the double-controller system of indication is slightly different with general distributed system here, please with reference to Fig. 1.First controller 110 has microprocessor 112, memory body 124 and network card 116; Second controller 120 is same has microprocessor 122, memory body 114 and network card 126; Two controllers all are provided with the Intranet IP address of different Intranet, and can grid line equipment such as (or with wireless network medium) to link each other be the small area network.Many hard disks 140 are used the common access data for first controller 110 is connected with second controller 120 with base plate 130 (backplane) polyphone.In other words, double-controller system can be considered the mininet that links with two computers that basic operation and network function arranged, but the shared single storage device of this two computers.
Next, the upgrade method of the storage area network equipment of multi-controller of the present invention is described.Fig. 2 and Fig. 3, it is respectively file method for updating flow chart and controller state sketch map on the dual controller of the present invention.Please with reference to Fig. 2, whether the method for the read-write capability of verification storage device is normal in order to the function of checking aforementioned first controller 110 and the single storage device of second controller, 120 accesses (being many hard disks 140 of Fig. 1), and it comprises the following steps:
Step S210: see through first controller second controller is sent fault transfer command (failover), and stop the running of second controller and write down the environment set of second controller;
Step S220: second controller is carried out refresh routine, in order to upgrade the operation procedure of second controller;
Step S230: after second controller was accomplished refresh routine, second controller sent fault recovery order (failback) to first controller, and restarts second controller;
Step S240: send the fault transfer command by first controller to second controller, and stop the running of first controller and write down the environment set of first controller;
Step S250: first controller is carried out refresh routine, in order to upgrade the operation procedure of first controller; And
Step S260: after first controller was accomplished refresh routine, first controller sent the fault recovery order to this second controller, and restarts first controller.
Because for guaranteeing controller in the process of upgrading, its running of can acting for sb of another controller.So when controller is desired to carry out ROMPaq, can send the fault transfer command to another controller.Fault transfer command role is: when a controller can't work on owing to upgrading, and the process that all accessing operations of this controller and services request are taken over by another controller pellucidly.And take over each item environment set that more comprises in the above-mentioned process as among Fig. 4:
Step S410: to the state of the memory device under the controller record of desiring to upgrade;
Step S420: the network service of taking over the controller of desiring to upgrade by the controller of carrying out refresh routine; And
Step S430: the services request of desiring to upgrade that controller received is forwarded to the controller of carrying out refresh routine.
Corresponding to the fault transfer command, after controller was accomplished upgrading, controller can require to return the order of the access service of being acted for sb to another controller, and this order is exactly the fault recovery order.Fault recovery order role is: if after the controller upgrading accomplishes, and after the normal again operation, the process that another controller can be taken over back accessing operation and services request again.
For the environment set of fault transfer command and fault transfer command, below with iSCSI document storage system with dual controller as explanation, and please refer to shown in Figure 5ly, it is the configuration diagram of iSCSI service of the present invention.The user sees through the iSCSI originating end iscsi target end is carried out duplicating of file.The iSCSI originating end can be selected one of them control end as file access from dual controller.Because the dual controller framework, system can provide the function of interleaving access to the user, so for the user, which controller the user need not make a choice to, also can reach the operation of equivalent environment.In other words, the user just connects one of them controller, but still can visit the virtual disk (virtual disk) on another controller.
The iSCSI service take-over is before IP is taken over by first controller 110, copies to first controller 110 to the iscsi target end on second controller 120.The connection of whole like this iSCSI service just can be taken on first controller 110 from second controller 120, and the task of former connection also is assigned in the correct connection.
The network convention service take-over is provided by the network management module in each controller.Network management module can let the network service on another controller, set up when the outer net service stopping of some controllers, is equivalent to let first controller 110 take over the service of second controller, 120 outer nets.The target that this correct network convention has been arranged, user's iSCSI originating end could be connected to first controller 110 with the TCP mode.
The adapter of the state of memory device is that the storage device management module by each controller provides; The thing that the storage device management module is made is through having revised the controller attribute of storage device management module; Transfer to the memory device of the virtual disk on the controller on another controller; The iSCSI service could be visited the virtual disk after taking over, and carries out normal read-write operation.The present invention is applied in the iSCSI document storage system except above-mentioned, can also be applied in the system of other multi-controllers.Service for other multi controller systems provided also has corresponding setting with memory device, is not only to limit to above-mentioned example.
Refresh routine (upgrade service) is a kind of finger daemon (daemon); Each controller all can be constantly the operation refresh routine; And see through transmission control agreement (Transmission Control Protocol is called for short TCP) mode and another controller is upgraded.Wherein, two controllers mode that can see through heartbeat line (heart beat) is got in touch.
Be each controller of convenient explanation multi-controller, therefore separated as the district with first controller 110 and second controller 120, its execution sequence is not limited to this.Suppose that second controller 120 carries out the controller of refresh routine for first.In Fig. 3 with from top to bottom as the flow direction of time.
Two controllers all can start the refresh routine (step a) of corresponding diagram 3 at the beginning in Fig. 3.Then, send the fault transfer command (step b) of corresponding diagram 3 by second controller 120 to first controller 110.After first controller 110 is accomplished the relevant environment of taking over second controller 120, will carry out the refresh routine (step c) of corresponding diagram 3 to second controller 120.
After accomplishing second controller, 120 completion refresh routines; Second controller 120 sends the fault recovery order to first controller 110; And return the relevant environment set of second controller 120, restart second controller 120 (steps d of corresponding diagram 3 and the step e).After second controller 120 has been confirmed normally to move; Then send the fault transfer command (step f) of corresponding diagram 3, and stop the running of first controller 110 and write down the environment set of first controller 110 to second controller 120 by first controller 110.Then, first controller 110 is carried out the refresh routine (step g) of corresponding diagram 3.And after first controller 110 is accomplished refresh routine; First controller 110 sends fault recovery order (the step h of corresponding diagram 3) to this second controller 120; Restart first controller 110 (step I of corresponding diagram 3), can accomplish the upgrading of document storage system.
