Description
Technical field
The present invention relates to computer realm, relate in particular to a kind of method, device and storage system that realizes that disk state is lit a lamp.
Background technology
Use a large amount of hard disks in the storage system, each hard disk requires corresponding hard disk indication lamp to indicate the various states of hard disk.Generally speaking, pilot lamp does not go out when the link of hard disk connects (LINK), and pilot lamp is long bright when hard disk link LINK, pilot lamp fast blink when hard disk carries out data transmission.
The scheme that the realization disk state of commonly using is at present lit a lamp has following two kinds:
Mode one, by serial connecting small computer system interface (Serial Attached SCSI, SAS) controller, perhaps Serial Advanced Technology Attachment (Serial Advanced Technology Attachment, SATA) controller produces.The prerequisite that this scheme realizes is that hard disk controller provides relevant pilot lamp signal.All can connect hard disk with backboard in the general storage system, like this in the more situation of hard disk, need more cabling, connector also needs more pin between eutergum, thereby sample can increase cost and design complexities.
Mode two, the READY LED signal by hard disk drives hard disk indication lamp.The hard disk drive that is connected with hard disk can provide according to the data transmission state of hard disk this READY LED signal, this READY LED signal is the high-low level signal, by this high-low level signal is outputed to hard disk indication lamp, can control the unlatching of hard disk indication lamp or close.This scheme does not need to connect a large amount of cablings from hard disk controller, but simplified design.In addition, even will put in the situation that modulating signal draws in the controller inconvenience, also can adopt this scheme.
According to the difference of hard disk type, the state of the READY LED signal of the hard disk drive output that connects with this hard disk may be not identical.For example, this signal of SATA normalized definition is device activity (Activity) output, exports when namely data transmission being arranged.According to the realization of different producers, that exports when data transmission is arranged may be low level signal (hard disk indication lamp is bright), also may just replace level signal (hard disk indication lamp flicker); It is high level signal (hard disk indication lamp goes out) when not having data transmission.
This signal of SAS normalized definition is that equipment is ready to (Ready) output or device A ctivity output, and the difference that arranges according to READY LED implication position (READY LED MEANING bit) is defined as follows respectively:
READY LED MEANING bit is 0: it is low level (hard disk indication lamp is bright) that equipment is ready to rear signal, for height replaces level signal (hard disk indication lamp flicker), is high level (hard disk indication lamp goes out) when equipment is not ready for when data transmission is arranged.
READY LED MEANING bit is 1: only being alternately level signal (hard disk indication lamp flicker) of height when data transmission is arranged, is high level (hard disk indication lamp goes out) when not having data transmission.
Because generally can use a large amount of hard disks in the storage system, and the type of hard disk might be not identical, like this, just might cause for same disk state, the indicating status of hard disk indication lamp is not identical, cause puzzlement for user's use.For example, for the SATA hard disk, when carrying out data transmission, its pilot lamp may be grown bright, and for the SAS hard disk, when READY LED MEANING bit was 0, equipment was ready to but does not carry out data transmission, and its pilot lamp also is long bright.And, even what use is the hard disk of same type, what for example use all is the SATA hard disk, also might exist because the difference of manufacturer causes for same disk state, the indicating status of hard disk indication lamp is not identical yet, for example, hard disk is when carrying out data transmission, and hard disk indication lamp might be long bright or flicker, and the flicker frequency of pilot lamp also may be inconsistent, even may look it is long bright because flicker is too fast.

For the hard disk that is in equal state that exists in the prior art, but the indicating status of hard disk indication lamp may not identical problem, the embodiment of the invention provides a kind of method that realizes that disk state is lit a lamp, device and storage system, be adjusted into unanimously by the represented implication of READY LED signal with dissimilar hard disks in the storage system, and READY LED signal is converted to the driving signal, drive hard disk indication lamp by described driving signal, so, can be so that in comprising the storage system of a plurality of hard disks, the indicating status that is in hard disk indication lamp corresponding to the hard disk of equal state is identical.
Fig. 1 is the method flow diagram that the realization disk state of the embodiment of the invention is lit a lamp.With reference to Fig. 1, described method can comprise the steps:
The method of the embodiment of the invention can be applied to have in the storage system of a plurality of hard disks.Comprise SAS hard disk and SATA hard disk in described a plurality of hard disk.In this step, the obtain manner of described type information is, reads the hardware description information of this hard disk from hard disk, determines the type information of hard disk according to this hardware description information.
As previously mentioned, SATA normalized definition READY LED signal is device A ctivity output, exports when namely data transmission being arranged; And SAS normalized definition READY LED signal is equipment Ready output or device A ctivity output, particularly, indication equipment Ready output when READY LED MEANING bit is 0 is when READY LED MEANING bit is that 1(is set) time indication equipment Activity output.
Therefore, in this step, after getting access to the type information of hard disk, when definite this hard disk was the SAS hard disk, the READY LED MEANING bit that this hard disk is corresponding carried out set, when definite this hard disk is the SATA hard disk, does not then process.Like this, just SAS hard disk and the represented implication of the READYLED signal of SATA hard disk are adjusted into unanimously, no matter namely be SAS hard disk or SATA hard disk, READY LED signal is device A ctivity output.Like this, just can avoid the data transmission state of SATA hard disk and READY LED MEANING bit is that the device ready of 0 SAS hard disk is obscured mutually.
