Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the process flow diagram of a kind of method of isolated fault hard disk in the embodiment of the present invention.The method goes for the isolated operation of faulty hard disk on hard disk array device.In actual applications, hard disk array device provides stores service for server, server constantly utilizes the hard disk in hard disk array device to carry out data storage at work, when there is write paths mistake in hard disk array device or having the faulty hard disk of hardware damage, server will send the instruction of isolated fault hard disk to hard disk array device immediately, prompting hard disk array device carries out isolated operation to faulty hard disk, to guarantee data security and server place system stable.Therefore, whois lookup is out of order after hard disk, and hard disk array device can adopt method as shown in Figure 1 to process.As shown in Figure 1, the method for the embodiment of the present invention can comprise the following steps:
Step S110, receives the instruction of isolated fault hard disk.Wherein, the instruction of isolated fault hard disk is that server is sent to hard disk array device, in this isolated fault hard disk instruction, carries positional information.
The isolated fault hard disk instruction that hard disk array device receives is the order of the protocol generation supported according to hard disk array device of server, as, the processor of the hard disk array device of the embodiment of the present invention is supported SCSI(Small Computer System Interface) agreement, the instruction of isolated fault hard disk can be for server is according to SCSI(Small Computer System Interface so) scsi command that sends of agreement.The embodiment of the present invention is not limited the form of isolated fault hard disk instruction.
The isolated fault hard disk instruction that this step receives is for pointing out hard disk array device that the hard disk of isolated fault hard disk instruction indication is removed, to reach physically-isolated effect, therefore carry positional information in the isolated fault hard disk instruction receiving, to specify exactly the faulty hard disk that need to remove.
Step S111, obtains the positional information of carrying in the instruction of isolated fault hard disk.
The content of mentioning as abovementioned steps S110, the instruction of isolated fault hard disk is the order of the protocol generation supported according to hard disk array device with server, therefore this step can be by resolving the instruction of isolated fault hard disk, obtain the positional information of carrying in the instruction of isolated fault hard disk, and this positional information is used to indicate the position that needs the faulty hard disk place that removes in hard disk array device.For example, can be for being integrated in the SES(Scsi Enclosure Service of hard disk array device for resolving the processor of isolated fault hard disk instruction) processor, it supports SCSI agreement, and the isolated fault hard disk instruction (scsi command) that can receive according to SCSI protocol analysis, obtain the positional information of carrying in instruction.
Step S112, removes the hard disk being inserted with on the corresponding hard disk slot of the positional information of carrying in the instruction of isolated fault hard disk, so that this hard disk is isolated.
The positional information indication hard disk that this step wish is obtained abovementioned steps is isolated, and for reaching more more reliable than prior art, effective isolation effect, this step is by the physical isolation realizing faulty hard disk.
Further selectable, step S112 can carry out the isolation of faulty hard disk in such a way:
First, remove fixing the hard disk being inserted with on the corresponding hard disk slot of this positional information.
Secondly, eject this hard disk, make this hard disk separated with hard disk slot.
It is that cooperation by software and hardware realizes that the embodiment of the present invention is carried out faulty hard disk isolation, for example, can form schematic diagram with reference to the structure of a unit in the array of the hard disk array device shown in Fig. 7: hard disk 2 is buckled 11 by the hard disk on hard disk chassis 1 hard disk 2 is fixed in hard disk chassis 1, hard disk 2 is inserted on the hard disk slot 12 of hard disk chassis 1, wherein, hard disk button 11 is controlled by the hard disk button control chip 13 of hard disk chassis 1, 13 of hard disk button control chips are controlled by the processor (as SES processor) of hard disk array device, the processor of hard disk array device can be controlled the hard disk button control chip 13 in the hard disk chassis 1 of unit in array.
Correspondingly, the processor of hard disk array device is resolved and is obtained after the positional information of carrying in instruction, the hard disk chassis 1 of the unit of this positional information indication will be removed fixing the hard disk 2 in malfunction: hard disk button control chip 13 generates hard disk button opening signals and is also sent to hard disk button 11, hard disk button 11 receives after hard disk button opening signal, the stiff end 111 for Fixed disk 2 of portable hard drive button 11 to stiff end 111 no longer contacts with hard disk 2, the position at stiff end 111 places of hard disk button 11 as shown in Figure 8.
In unit shown in Fig. 7, hard disk chassis 1 also comprises the spring assembly 14 in compressive state, in the process that the stiff end 111 of hard disk button 11 moves, spring assembly 14 also by the static solution due to hard disk 1 except and recover gradually spring type and become, accordingly, the hard disk 2 that spring assembly 14 contacts the contact jaw with spring assembly 14 141 by restoring force ejects, make hard disk 2 separated with hard disk slot 12, as shown in Figure 8, now the hard disk 2 in released state cannot access hard disk chassis 1 by the mode of automatically reset (electrification reset) with hard disk slot 12, the method of the embodiment of the present invention has reached the physical isolation that makes the hard disk 2 that breaks down, avoided faulty hard disk in prior art to fail to realize physical isolation and automatically reset hidden danger.
The method that realizes faulty hard disk isolation described above is by the form realization of software and combination of hardware, as chip, interlock circuit and physical construction, the embodiment of the present invention is not limited for realizing software, the hardware unit that faulty hard disk isolation adopts.
Beyond method described above, can also there be the methods that realize above-mentioned isolation effect more, as by the automatic extracting apparatus of software control, the indicated faulty hard disk of server to be extracted and is placed on assigned address etc., the above method providing is provided the embodiment of the present invention.
