Background
On the back plate of the storage server, each hard disk slot is provided with an in-place indicator light for indicating whether the hard disk is in place or not. However, the indicator light has a very limited effect, and if the hard disk is inserted into the slot, the indicator light will illuminate, indicating that the hard disk is in place. But the following problems are encountered during actual use:
during the use process of the hard disk, firmware damage may occur, so that the operating system cannot identify the hard disk, and thus, the hard disk cannot be read and written. In this case, however, the indicator light of the hard disk will also show a green color indicating that the hard disk is still inserted on the back plate. At this time, it cannot be judged by the indicator lamp that the hard disk has failed at this time.
In a dual-control or multi-control environment, several control units share a storage system, but not all control units can correctly detect the hard disk and read and write the hard disk normally. For example, in such a case, the main board a is operating normally in the dual-control environment, the main board B is in a waiting state, the main board a detects that the hard disk is in place, so that the in-place indicator light of the hard disk displays green, but the main board B does not detect the hard disk.

Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
The following explains key terms appearing in the present invention.
BMC, execution server remote management controller, english name Baseboard Management controller. The method can perform firmware upgrade, check machine equipment and other operations on the machine in a state that the machine is not started. Fully implementing IPMI functionality in a BMC requires a powerful 16-bit or 32-bit microcontroller and RAM for data storage, flash memory for non-volatile data storage, and firmware to provide basic remote manageability in terms of secure remote reboot, secure re-power-up, LAN alerting, and system health monitoring. In addition to the basic IPMI and system operation monitoring functions, the mBMC can also enable BIOS flash element selection and protection by storing the previous BIOS using one of the 2 flash memories. For example, when the system fails to boot after a remote BIOS upgrade, the remote administrator may switch back to the previously-working BIOS image to boot the system. Once BIOS is upgraded, the BIOS image can be locked, so as to effectively prevent virus from invading it.
The CPLD complex programmable logic device mainly comprises three parts, namely a logic block, a programmable interconnection channel and an I/O block.
FIG. 1 is a schematic flow chart of a method of one embodiment of the invention. The execution body of fig. 1 may be a hard disk indicator light control system.
As shown in fig. 1, the method includes:
step 110, identifying all controllers of the hard disk indicator lamp, and generating a control time sequence by setting the control time and the control sequence of each controller in a control period, wherein the control time sequence comprises a plurality of control periods;
and step 120, according to the control time sequence, enabling each controller to control the state of the hard disk indicator lamp according to the state of the hard disk in sequence.
In order to facilitate understanding of the present invention, the principle of the method for controlling a hard disk indicator lamp according to the present invention is used to further describe the method for controlling a hard disk indicator lamp according to the present invention in combination with the process of controlling a hard disk indicator lamp in the embodiment.
In order to improve the reliability of the equipment, the storage server generally adopts a multi-control design, namely a plurality of control units, only one control unit works in normal operation, and when the main control unit in operation breaks down and is down, the redundant control unit can immediately enter into a working state to replace the working of the main control unit, so that the whole storage server is prevented from being stopped. Just like a computer has two mainboards, only one of the mainboards works in normal operation, and the other is in a waiting state, when the working mainboard breaks down, the waiting mainboard immediately takes over the working of the working mainboard, so that the system operates normally. However, in one storage node, only one storage system at the back end is provided, that is, a plurality of controllers share one storage system, and the control unit is connected with the hard disk at the back end through the back plate. Just like the two main boards described above share one hard disk. But often there are up to tens of hard disks on the back end in the storage server.
Specifically, referring to fig. 2, the present invention is described by taking two controllers, which are a controller a and a controller B, respectively, where the controller a and the controller B each include a set of respective BMCs and CPLDs, and the hard disk indicator light control method includes:
s1, identifying all controllers of the hard disk indicator lamp, and generating a control time sequence by setting control time and control sequence of each controller in a control period, wherein the control time sequence comprises a plurality of control periods.
And selecting a master controller from all controllers, wherein the master controller receives identity information sent by other controllers, for example, selecting a first controller as the master controller, and sending the identity information to the first controller by a second controller. After the first controller receives the identity information of the first controller, the first controller caches the second controller identity information and the local first controller identity information, wherein the identity information can be a controller identity ID. The first controller sorts the identity information of all controllers by utilizing a random function, and takes the sorting result as the control sequence of each controller in a control period; the first controller distributes control time for each controller averagely according to the set control period duration, and arranges the control time of the controllers according to the control sequence to obtain a control period; the first controller transmits the timing composed of the cyclic control periods as a control timing to the second controller.
For example, the controller a acquires the identity ID of the controller B, and sets the control time of the controller to 1s. The control sequence of the random generation is that the controller A is in front and the controller B is in back. The controller a generates a control period t= [ a (1 s), B (1 s) ], representing that one control period has a duration of 2s, the former 1s being the control time of the controller a and the latter 1s being the control time of the controller B. The control timing is generated based on the control period T, i.e., the loop execution control period T.
For ease of observation, a waiting period 2s may be set. The waiting period is added between adjacent control periods among timings composed of the cyclic control periods, and the timing to which the waiting period is added is regarded as a control timing when the control timing is [ a (1 s), B (1 s), (2 s), … ].
At this time, the controller a first selects the first half sequence, and generates a first control time [0:00-0:01,0:02-0:03,0:04-0:05, … ] assuming that the current time is 0:00. The BMC of the controller A sends the first control time to the BMC of the controller B, and the BMC of the controller B selects the second half section sequence based on the first control time to obtain a second control time [0:01-0:02,0:03-0:04,0:05-0:06, … ].
S2, according to the control time sequence, enabling each controller to control the state of the hard disk indicator lamp according to the state of the hard disk in sequence.
The controller splits a sub-control time sequence corresponding to the controller from the control time sequence according to the control sequence, the control time and the control period duration in the control period; the controller starts timing when receiving the hard disk indicator lamp control program starting signal, and controls the state of the hard disk indicator lamp when the timing time is within the control time range of the sub-control time sequence.
For example, at this time, the controller a first selects the first half sequence, and assuming that the moment of receiving the start signal is 0:00, the sub-control sequence of the controller a is split from the control sequence to be [0:00-0:01,0:02-0:03,0:04-0:05, … ]. The sub-control time sequence of the controller B is [0:01-0:02,0:03-0:04,0:05-0:06, … ]. The controller A and the controller B start timing at 0:00, and when the timing time of the controller A starts to control the hard disk indicator lamp at 0:00 and the timing time reaches 0:01, the control is stopped; and when the timing time of the controller B is 0:01, the hard disk indicator lamp is controlled, and the control is stopped when the timing time reaches 0:02.
The BMCs of the two controllers can acquire signals from the hard disk slots to judge whether the hard disk is in place, and when the hard disk is detected to be in place, the BMCs read the information of the idle area of the hard disk and judge whether the hard disk can be read and written normally by judging whether the information can be read. When the BMC of the controller knows the state of the hard disk, the corresponding state code is sent to the CPLD, and the CPLD controls the hard disk indicator lamp through the information from the hard disk.
When only one controller can identify that the hard disk works normally and the other controller does not identify that the hard disk works normally, at the moment, both controllers control the hard disk indicating lamp at the control time of the controller, the controller identifying that the hard disk works normally turns green at the control time of the controller, the indicating lamp not identifying that the hard disk works normally turns dark at the control time of the controller, and at the moment, the indicating lamp of the hard disk flashes to indicate that the controller does not identify the hard disk correctly. Only when both controllers recognize that the state of the hard disk is normal, the respective control times of both controllers are normally bright green, so the indicator lamp will always be normally bright green.
The control logic of the invention also has self-adaptive capability under the multi-control environment, when three controllers exist, the BMCs of the three controllers only need to mutually negotiate when starting up to determine the control time of the indicator lamp, so that the control logic can be used in the three-control environment. At this time, the control time in one control period is 3, and each controller controls the indicator lamp in turn in the own control time. When there is only one controller, there is only one control time and the control logic is degraded to ordinary hard disk indicator light control logic.
As shown in fig. 3, the system 300 includes:
a timing generation unit 310 for identifying all controllers of the hard disk indicator lamp and generating a control timing by setting a control time and a control order of each controller in a control period, the control timing including a plurality of control periods;
