Description
Technical field
The present invention relates to communication technical field, particularly a kind of disk array backup method, electronic equipment andDisk array.
Background technology
For the object of disaster-tolerant backup, general disk array all requires to realize dual-active, in different faultsIn region, set up two disk arrays (or being called data center), two disk arrays can backup each other.In the time that one of them disk array breaks down, cannot provide service, another disk array can continue workDo, so that work can continue.
Current disk array dual-active scheme, mainly reports main frame by disk array inside to selfLUN (logicalunitnumber, logical unit number) does camouflage and processes, and makes the main frame can be by twoThe LUN that array reports is identified as same LUN. Between two arrays, data are done synchronously and copied simultaneously, withEnsure the uniformity of data. Wherein, in general, LUN is used to refer to for disk storage unit (logicalunitdevice)。
Current dual-active scheme, step is roughly as follows:
1, disk array A is using the LUN_A of self as main LUN;
2, disk array B is using the LUN_B of self as from LUN;
3, LUN_A and LUN_B are set up remote copy relationship by user, ensures that the data of these two LUN are completeComplete consistent;
4, user sends instruction to disk array A and disk array B simultaneously, to make disk array A and diskArray B shines upon LUN_A and LUN_B to main frame respectively simultaneously. And disk array B is reflecting LUN_BPenetrate in the process to main frame, the characteristic information of LUN_B can be disguised oneself as identical with LUN_A.
5, the multi-path software of main frame is after scanning LUN_A and LUN_B, due to the feature letter of the twoManner of breathing is same, and main frame can think that the two is the different paths of same LUN, and is taken over as sameLUN。
6, the business of host side, by the forwarding of multi-path software, sends to arbitrarily on a LUN. TwoData between LUN can automatic synchronization.
So, after the disk array at a LUN place breaks down, can be by the machine of switching of multipathSystem is switched to another LUN and continues business.
The shortcoming of this technology:
The main technical point of existing dual-active scheme all concentrates on disk array end, and this just means establishment dual-activeTwo disk array inside all must realize the function relevant to dual-active separately. This has also just limited existingDual-active scheme can only be applicable to the situation that two disk arrays are all same manufacturers, and to two disk battle arraysFramework, the software version etc. of row have particular/special requirement, generally to ensure as far as possible two disk arrays framework,Software versions etc. are identical or close.
Visible, in prior art, (be different vendor or different framework, difference for heterogeneous disk arraySoftware version etc.) temporarily cannot realize dual-active, also just can not carry out good disaster-tolerant backup.

The embodiment of the present invention wouldn't relate to masterThe dual-active scheme of machine, therefore, in the embodiment of the present invention, the function of main frame can be regarded as equally, namelySay, below the main frame introduced, can refer to any main frame in Fig. 1.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
Refer to Fig. 2, the embodiment of the present invention provides a kind of disk array backup method, and described method can be answeredFor electronic equipment, in the embodiment of the present invention, electronic equipment can refer to main frame, and described electronic equipment is passableServer, PC (personal computer) etc. different equipment. In the embodiment of the present invention, described electronics is establishedThe standby function of carrying out, can refer to the performed function of multi-path software of installing in described electronic equipment. InstituteThe main flow process of stating method is described below.
Step 201: in the time receiving a LUN of the first disk array mapping and the 2nd LUN, according toThe Mapping and Converting table of storage, is revised as the characteristic information of described the 2nd LUN identical with a described LUNCharacteristic information, with by a described LUN and the same LUN of described the 2nd LUN disguise as; Wherein,A described LUN is the mirror image LUN being made up of described the 2nd LUN and the 3rd LUN, described secondLUN belongs to second disk array, and described the 3rd LUN belongs to described the first disk array, described the first magneticDisk array and described second disk array are heterogeneous disk array.
For example, described the first disk array is the redundant array of inexpensive disks 1 in Fig. 1, and described second disk array is figureDisk array 2 in 1, described in the electronic equipment is shown in figure 1 can be any of the host.
0.060000In the embodiment of the present invention, this mirror image LUN is called to a described LUN, described the first disk array can be by instituteState a LUN and described the 2nd LUN all shines upon to described electronic equipment.
In described electronic equipment, store described Mapping and Converting table, described electronic equipment can be according to described mappingConversion table, is converted to the characteristic information identical with a described LUN by the characteristic information of described the 2nd LUN.
In the embodiment of the present invention, the characteristic information of LUN, can comprise WWN (WorldWideName,The unique name in the whole world), one in productID (product identification), venderID (producer's mark) orSeveral, certainly can also comprise other for representing the information of identity of a LUN.
For example, the multi-path software internal maintenance of installing in described electronic equipment has described Mapping and Converting table,The WWN that supposes a described LUN is AAA, and the WWN of described the second common LUN is BBB. CanIn described Mapping and Converting table, increase a list item, that is: BBB is converted to AAA.
So, in the time that a described LUN and described the 2nd LUN are shone upon to described electronic equipment, described manyRouting software, according to the content in described Mapping and Converting table, is converted to AAA by BBB automatically, makes search electricityUpper-layer service software in subset can only be seen the LUN that a WWN is AAA, thereby completes describedThe camouflage of the one LUN and described the 2nd LUN.
That is to say, for described electronic equipment, receive described the first Array Mapping LUN, completeTo receive LUN camouflage and follow-up be data selection transmit path, be all by described multi-path softwareComplete, and that upper-layer service software in described electronic equipment is only responsible for sending the data to described multipath is softPart.
Certainly,, if except WWN, also need the productid of described the 2nd LUN, venderidAlso be converted to the characteristic information identical with a described LUN Deng characteristic information, so at described Mapping and ConvertingIn table, increase corresponding list item, described multi-path software can be changed in the lump.
Wherein, the characteristic information of a described LUN, can be identical with the characteristic information of described the 3rd LUN.
Step 202: a described LUN is configured to main LUN, to give described main LUN by data distributingCorresponding disk array.
Described electronic equipment after same LUN that a described LUN and described the 2nd LUN are disguised oneself as,A described LUN can be configured to main LUN, like this, while issuing data more afterwards, all can first selectSelect data distributing to disk array corresponding to described main LUN. Because described main LUN is mirror image LUN,Actual described the 2nd LUN and described the 3rd LUN of having comprised in described main LUN, therefore, describedWhen one disk array and the equal fault-free of described second disk array, described main LUN can be regarded as and instituteState all LUN of correspondence of the first disk array and described second disk array. And described the 2nd LUN is only correspondingIn described second disk array.
Optionally, in the embodiment of the present invention, after a described LUN is configured to main LUN, also bagDraw together:
Give corresponding described the first disk array and the described second disk of described main LUN by the first data distributingArray.

Optionally, in the embodiment of the present invention, after a described LUN is configured to main LUN, also bagDraw together:
Give corresponding described the first disk array and the described second disk of described main LUN by the second data distributingArray;
Receive the error reporting for described the second data, determine described the first magnetic according to described error reportingDisk array fault;
Again give described second disk array corresponding to described the 2nd LUN by described the second data distributing.
Same, described electronic equipment, will by the upper-layer service software of described electronic equipment in the time issuing dataDescribed the second data distributing is given described multi-path software, by described multi-path software selecting paths, because described inThe one LUN is main LUN, and therefore described multi-path software is preferentially selected described the second data distributing to instituteState a LUN. And if described the first disk array fault now, so described electronic equipment will receiveTo described error reporting, determine described the first disk array fault, now, described electronic equipment can be againDescribed the second data are issued, because known described the first disk array fault, therefore described electronics is establishedStandby can selection described the second data distributing to the described second disk array corresponding with described the 2nd LUN.
And if described second disk array fault, described electronic equipment still can continue described secondData distributing is given disk array corresponding to a described LUN, now disk battle array corresponding to a described LUNRow have just only been left described the first disk array.
That is to say, described the first disk array has control action to a described LUN, when describedWhen one disk array fault, a described LUN cannot re-use all over, and when described second disk battle arrayWhen row fault, described the 3rd LUN in a described LUN can also continue to use.
Refer to Fig. 3, based on same inventive concept, the embodiment of the present invention provides another kind of disk array backupMethod, described method can be applied to foregoing the first disk array. The main flow process of described method asUnder.
Step 301: the 2nd LUN that belongs to described second disk array that receives second disk Array Mapping;Described the first disk array and described second disk array are heterogeneous disk array.
