In the hardware design of the server, the server is generally divided into a main board and a hard disk backplane, wherein the main board includes key service components such as a CPU, and the hard disk is connected to the hard disk backplane, some hard disk information with high real-time requirements is collected by a control chip (e.g., CP L D) on the hard disk backplane and then transmitted to the BMC on the main board.
As shown in fig. 6, the hard disk backplane and the motherboard are connected by a cable, and the hard disk backplane includes six signal lines, i.e. six paths, as follows:
two paths of I2C signals including SDA and SC L are connected to the CP L D of the hard disk backboard by the BMC;
two paths of GPIO signals including GPIO1 and GPIO2 are connected to the hard disk backplane CP L D through the mainboard CP L D;
the hard disk backboard is grounded through a pull-down resistor and then connected to GPIO3 of the mainboard CP L D;
and the ground signal ensures that the hard disk back plate and the main board are grounded and the electric potential of the system is consistent.
The realization process is as follows:
the method comprises the steps of hard disk backboard power-on control and power failure detection, 2 GPIO signals are used, a main board CP L D detects that a hard disk backboard is in place, after equipment receives a power-on signal, the GPIO1 of the main board CP L D informs the hard disk backboard CP L D of starting power, the main board CP L D starts timing, the hard disk backboard CP L D waits for a power normal signal to be returned through the GPIO2, if the timing is completed, the main board CP L D does not receive the power normal signal, the power-on is stopped and an alarm is given, if the timing is completed, the main board CP L D receives the power normal signal, the power is continuously started until the power-on is completed, and after the power-on is completed, the main board CP L.

However, the above solutions have disadvantages that the hard disk is plugged or disconnected, the hard disk backplane CP L D cannot actively inform the BMC, the BMC needs to access the hard disk backplane CP L D in a polling manner, and occupies more resources of the BMC, while the hard disk information change is a relatively low-frequency event, and the polling manner is a fixed-interval access, so that the real-time performance is not high, the response is slow, and to improve the real-time performance, the polling interval must be shortened, more BMC resources are consumed, and the operation of other services is affected.
In view of the above, the present disclosure provides a hard disk management method, an apparatus, an electronic device, and a machine-readable storage medium to solve the problem of high BMC resource consumption.
The specific technical scheme is as follows.
In an actual server environment, there may be one or more hard disk backplanes CP L D and corresponding hard disks, and the hard disk backplane CP L D may be directly connected to the BMC and/or the motherboard CP L D, or indirectly connected to the BMC and/or the motherboard CP L D through one or more devices and cables that do not change signals and data transmission, and the embodiments provided by the present disclosure are not affected by the number of the hard disk backplanes CP L D, so in order to describe the technical solution of the present disclosure more conveniently and clearly, in the process of describing the embodiments, an unspecified hard disk backplane CP L D is used as the hard disk backplane CP L D in the embodiments.
In one embodiment, the hard disk management method is applied to BMC and comprises the steps of obtaining interrupt information, wherein the interrupt information is obtained according to interrupt signals, the interrupt signals are sent by a hard disk backboard CP L D when a hard disk connected with the hard disk backboard CP L D is abnormal, determining the hard disk CP L D connected with an abnormal hard disk according to the interrupt information, obtaining hard disk abnormal information of the hard disk CP L D connected with the abnormal hard disk, and refreshing the hard disk information according to the hard disk abnormal information.
Specifically, as shown in fig. 1, the present embodiment includes the steps of:
in step S11, interrupt information is acquired.
The interrupt information is obtained according to an interrupt signal, and the interrupt signal is sent by a hard disk backboard CP L D when the hard disk connected with the hard disk backboard CP L D is abnormal, wherein the interrupt signal is BMC
And step S12, determining the hard disk CP L D connected with the abnormal hard disk according to the interrupt information.
And step S13, acquiring the abnormal hard disk information of the hard disk CP L D connected with the abnormal hard disk, and refreshing the hard disk information according to the abnormal hard disk information.
In this embodiment, the BMC does not actively poll and access each hard disk backplane CP L D, but only acquires the hard disk exception information of the hard disk CP L D connected with the abnormal hard disk according to the interrupt information obtained by the interrupt signal sent by the hard disk backplane CP L D, and then refreshes the hard disk information according to the hard disk exception information, thereby reducing resource consumption of the BMC.
The hard disk abnormity of the present disclosure refers to any abnormal operation state of hard disk failure, offline, power failure, etc.
The hard disk management process is completed, so that the BMC resource occupied by the refreshing of the hard disk information is reduced.
As a technical scheme, an interrupt information channel is connected between the BMC and the mainboard CP L D, the interrupt information is obtained according to an interrupt signal, the interrupt signal is sent by the hard disk backboard CP L D when a hard disk connected with the hard disk backboard CP L D is abnormal, the interrupt information is obtained from the mainboard CP L D through the interrupt information channel, and the interrupt information is obtained by the mainboard CP L D according to the received interrupt signal sent by the hard disk backboard CP L D.
As shown in fig. 2, an interrupt information path is connected between the BMC and the motherboard CP L D, that is, an interrupt information path between the GPIO1 of the BMC and the GPIO4 of the motherboard CP L D, and the motherboard CP L D receives an interrupt signal sent by the hard disk backplane CP L D and performs logic processing according to the interrupt signal, so that once an abnormality occurs in the hard disk connected to the hard disk backplane CP L D, the BMC can receive interrupt information from the motherboard CP L D through the L ocal Bus.
As a technical solution, the determining, according to the interrupt information, the hard disk CP L D connected with the abnormal hard disk includes querying a storage unit of the main board CP L D, and determining, according to the queried abnormal record of the hard disk CP L D, the hard disk CP L D connected with the abnormal hard disk, where the abnormal record of the hard disk CP L D is obtained by the main board CP L D according to the received interrupt signal.
After the main board CP L D receives the interrupt signal sent by the hard disk backplane CP L D, the information of the hard disk backplane CP L D that sends the interrupt signal is recorded and stored in its own storage unit, such as a register, so that the BMC can query which hard disk backplane CP L D is connected with the abnormal hard disk in the storage unit of the main board CP L D.
As a technical scheme, whether the function of sending an interrupt signal is enabled or not is judged by the hard disk back plate CP L D, if so, the method is executed, the interrupt information is obtained according to the interrupt signal, the interrupt signal is sent by the hard disk back plate CP L D when the hard disk connected with the hard disk back plate CP L D is abnormal, the hard disk CP L D connected with the abnormal hard disk is determined according to the interrupt information, and the hard disk abnormal information of the hard disk CP L D connected with the abnormal hard disk is obtained.
If the hard disk backplane CP L D does not enable the function of sending the interrupt signal, the function may not be started by the hard disk backplane, or the function may not be supported by the hard disk backplane, and the BMC can still refresh the hard disk information in a polling mode, so that the compatibility of the technical scheme is improved.
The method for acquiring the hard disk abnormal information of the hard disk CP L D connected with the abnormal hard disk and refreshing the hard disk information according to the hard disk abnormal information comprises the steps of accessing and only accessing the hard disk CP L D connected with the abnormal hard disk, acquiring the hard disk abnormal information of the hard disk CP L D connected with the abnormal hard disk and refreshing the hard disk information according to the hard disk abnormal information in the step.
Compared with the technical scheme, in the embodiment, only the hard disk CP L D connected with the abnormal hard disk is accessed, so that the consumption of BMC resources is further reduced.
The method comprises the steps of accessing a storage unit of a main board CP L D, obtaining hard disk abnormal information of a hard disk CP L D connected with an abnormal hard disk, and refreshing the hard disk information according to the hard disk abnormal information, wherein the hard disk abnormal information stored in the storage unit of the main board CP L D is obtained by the main board CP L D accessing the hard disk CP L D connected with the abnormal hard disk.
The mainboard CP L D collects the hard disk abnormal information reported by the hard disk backboard CP L D, and the BMC acquires the information from the mainboard CP L D, so that the condition that the BMC needs to inquire the plurality of hard disk backplates CP L D when the plurality of hard disk backplates CP L D send interrupt signals is avoided, and the BMC resource consumption is further reduced.
As a technical scheme, the main board CP L D and the hard disk CP L D are provided with four signal paths, the main board CP L D accesses the hard disk CP L D through the four signal paths, and the four signal paths are provided with switches, and the four signal paths are switched to open or close the JTAG function.
As shown in fig. 3, the hard disk backplane and the motherboard are still connected by six paths, wherein the hard disk backplane CP L D is no longer connected to the BMC via the I2C bus, and the two paths thus vacated are connected to the motherboard CP L D, so that four signal paths are formed between the motherboard CP L D and the hard disk CP L D.
In order to support the inherent procedure of JTAG upgrading the hard disk backplane CP L D, four signal paths are required between the main board CP L D and the hard disk backplane CP L D, and these 4 four signal paths are used for JTAG signals.
In order to support the BMC to collect the hard disk information in an interrupt mode, signals are needed to transmit the hard disk information between the main board CP L D and the hard disk backplane CP L D.
Information is transmitted between the main board CP L D and the hard disk back board CP L D through common GPIO, and the JTAG function is switched to only when the inherent program of the hard disk back board CP L D is required to be upgraded by JTAG, so JTAGEN of the hard disk back board CP L D is required to be invalid by default.
Then the hard disk backplane is designed with the following two conditions: if JTAG is high effective, that is, JTAG is high, the hard disk backplane pulls down GPIO1 signal to be used as the hard disk backplane in place, and then directly connects GPIO1 to JTAG pin. If JTAG is active low, that is, JTAG is low, the hard disk backplane pulls down the GPIO1 signal to be used as the hard disk backplane, and then connects the pulled down signal to JTAG pin after passing through an inverter.
The design of the main board CP L D needs to configure GPIO1 into a bidirectional pin to support input and output, the GPIO1 defaults to input, does not drive the external device and detects an in-place signal of the hard disk backboard, only needs JTAGEN for controlling the hard disk backboard CP L D to output the signal externally, and does not detect the in-place signal of the hard disk at the moment and does not need detection.
The second stage of the change-over switch is two-way input and one-way output, a plurality of second stage of the change-over switch are required to be designed, one second stage of the change-over switch corresponds to each hard disk backplane, the output of the second stage of the change-over switch is 4 common GPIO signals to each hard disk backplane, the input of the second stage of the change-over switch is JTAG signals from BMC (output from the first stage of the change-over switch) and signals from a main board CP L D register module, the first stage of the change-over switch is one-way input and multi-way output, only one first stage of the change-over switch is required to be designed, the input of the first stage of the change-over.
The register module of the main board CP L D needs to provide control bits of the switch and JTAG en for BMC direct control.
After the user initiates the online upgrade operation, the BMC accesses the CP L D register module of the mainboard, and enables the control bit corresponding to the hard disk backplane, and the CP L D register of the mainboard is communicated through L ocal Bus protocol.
After the main board CP L D detects the control bit is enabled, the two-stage switch is turned on, the JTAG signal of BMC is output to the corresponding hard disk backboard, meanwhile, GPIO1 is configured to output, and high level is output to the JTAGEN pin of the hard disk backboard CP L D, at this time, the JTAG pin of the hard disk backboard CP L D is configured to be a special pin.
The BMC can access the NVCM of the hard disk backplane CP L D through JTAG to upgrade the firmware program.
After the upgrade is completed, the BMC needs to release the control bit, and after the main board CP L D detects the release of the control bit, the path is immediately switched back to the default state, so as to ensure the collection of the information of the hard disk backplane.
The data transmission protocol between the main board CP L D and the hard disk back board CP L D is realized through four GPIOs, a protocol similar to SGPIO can be adopted, and when hard disk information is collected, power supply enabling and power supply states need to be transmitted so as to ensure the realization of power-on control and power supply state detection.
The register module of the main board CP L D needs to set 1 SGPIO signal for each hard disk backplane at the same time to collect all hard disk information of the entire server, the main board CP L D needs to arrange all hard disk information according to the actual physical slot number, and the hard disk backplane CP L D is only similar to a hard disk information sensor.
When the main board CP L D detects that the information of any hard disk changes, an interrupt signal is generated and transmitted to the BMC.
In an embodiment, the present disclosure provides a hard disk management device, as shown in fig. 4, applied to BMC, the device includes an information module 21 configured to obtain interrupt information, where the interrupt information is obtained according to an interrupt signal, where the interrupt signal is sent by a hard disk backplane CP L D when an abnormality occurs in a hard disk connected to the hard disk backplane CP L D, a processing module 22 configured to determine a hard disk CP L D connected to an abnormal hard disk according to the interrupt information, and a management module 23 configured to obtain hard disk abnormality information of the hard disk CP L D connected to the abnormal hard disk, and refresh the hard disk information according to the hard disk abnormality information.
The BMC does not actively poll and access each hard disk backboard CP L D, only acquires the hard disk abnormal information of the hard disk CP L D connected with the abnormal hard disk according to the interrupt information obtained by the interrupt signal sent by the hard disk backboard CP L D, and then refreshes the hard disk information according to the hard disk abnormal information, so that the resource consumption of the BMC is reduced.
