Example 1
Fig. 1 is a schematic flow chart illustrating a method for quickly positioning a hard disk under a disk array according to this embodiment. As shown in fig. 1, the method for quickly locating a hard disk under a disk array includes:
step S100, receiving a disk array confirmation instruction;
step S200, inquiring whether a storage device of a hard disk in a server has a corresponding disk array or not based on the disk array confirmation instruction, and acquiring corresponding hard disk information under the disk array when the corresponding disk array exists in the server;
and step S300, controlling the corresponding hard disk lamp to operate based on the hard disk information, and realizing the positioning of the hard disk.
The following describes the steps S100 to S300 of the method for quickly positioning a hard disk under a disk array according to this embodiment in detail.
Step S100, a disk array confirmation instruction is received.
In this embodiment, a user (operation and maintenance staff of the server) sends a disk array confirmation instruction to the Baseboard Management Controller (BMC), and the baseboard management controller receives the disk array confirmation instruction.
In this embodiment, the user and the bmc interact with each other through a predefined IPMI (Intelligent Platform Management Interface) command.
In this embodiment, the method further includes: configuring an IPMI command format, and configuring an IPMI command for sending a disk array validation command based on the IPMI command format. The configured IPMI command format and the configured IPMI command for sending the raid confirmation instruction are shown in table 1:
TABLE 1
| Command definition | Parameter(s) | Description of the invention |
| Function code | 0x3A | Vendor-defined (IPMI command must field) |
| Command word | 0x30 | Vendor-defined (IPMI command must field) |
| Request field | Byte 1: RAID group number requiring illumination | |
| Response field | Byte 1: return code |
And sending the IPMI command to a substrate management controller through an IPMI command sending tool, and processing the IPMI command containing the disk array confirmation command by the substrate management controller.
Step S200, whether a corresponding disk array exists in the storage device of the hard disk in the server is inquired based on the disk array confirmation instruction, and when the corresponding disk array exists in the server, corresponding hard disk information under the disk array is obtained.
The hard disk information includes, but is not limited to, a hard disk serial number, a hard disk location, and the like.
Fig. 2 is a schematic diagram illustrating a principle process of acquiring hard disk information corresponding to a disk array in the method for quickly positioning a hard disk under the disk array according to the embodiment. As shown in fig. 2, in this embodiment, the process of querying whether a corresponding disk array exists in the storage device of the hard disk in the server based on the disk array confirmation instruction is as follows:
firstly, the baseboard management controller firmware analyzes the disk array confirmation instruction to obtain a disk array group number required to be inquired, then, the baseboard management controller firmware accesses a disk array card in the baseboard management controller based on the disk array group number, and receives corresponding hard disk information under the disk array from the disk array card.
In this embodiment, the management of the hard disk and the hard disk array in the server is realized by the disk array (RAID) management provided by the disk array card in the baseboard management controller and by the baseboard management controller directly accessing the disk array (RAID) card.
The implementation of providing disk array (RAID) management via a disk array card in a baseboard management controller is as follows:
a manufacturer of a disk array (RAID) card provides an interface for operating a hard disk to a baseboard management controller through software in the RAID card, and the baseboard management controller manages the hard disk through the interface provided by the RAID card. Since providing disk array (RAID) management via a disk array card is well known to those skilled in the art, it is not described in detail herein.
In this embodiment, the baseboard management controller firmware parses the disk array validation command based on the IPMI command format to obtain the disk array group number to be queried.
Specifically, in this embodiment, as shown in table 1 above, the bmc defines fields of the IPMI command, the user sends the IPMI command to the bmc according to the defined fields of the IPMI command, and the bmc parses the disk array group number to be queried (i.e. the RAID group number to be lit) according to the IPMI command definition.
For example, the user needs to light hard disk information of RAID 0: the user sends a command: ipmitool raw 0x3A 0x300x 00; (wherein ipmitool is an open source IPMI command transmission tool), the baseboard management controller analyzes that the field data of the request is 0x00, that is, the hard disk under RAID 0 needs to be lighted.
As shown in fig. 2, after the baseboard management controller analyzes the disk array group number requested to be lit by the user, it may query whether the disk array group exists through the disk array (RAID) management provided by a disk array (RAID) card, and if the disk array group exists, continuously obtain all hard disk information (serial number, location, etc.) under the disk array group, and return the hard disk information to the baseboard management controller, so that the baseboard management controller realizes the location of the hard disk according to the returned hard disk information.
And step S300, controlling the corresponding hard disk lamp to operate based on the hard disk information, and realizing the positioning of the hard disk.
Fig. 3 is a schematic flowchart illustrating a process of positioning a hard disk in the method for quickly positioning a hard disk under a disk array according to this embodiment. Specifically, in this embodiment, as shown in fig. 3, the controlling the operation of the corresponding hard disk lamp based on the hard disk information includes:
and S310, controlling hard disk lamps corresponding to all hard disks in the disk array to be lightened on based on the hard disk information, and realizing the positioning of all hard disks in the disk array.
And step S320, controlling each hard disk lamp to flicker successively based on a preset sequence, and realizing the positioning of a single hard disk.
The flash frequency and the flash times of the hard disk lamp are customized by a user. For example, the frequency of flickers is 1HZ, and the number of flickers is 2.
In this embodiment, the preset sequence is, but not limited to, a sequence from large to small of the serial numbers of the hard disks, a sequence from small to large of the serial numbers of the hard disks, a sequence from left to right of the positions of the hard disks, a sequence from right to left of the positions of the hard disks, a sequence from large to small of the load capacity of the hard disks, or a sequence from small to large of the load capacity of the hard disks.
For example, the hard disk lamps are controlled to flash gradually according to the sequence of the hard disk serial numbers from large to small, and the positioning of a single hard disk is realized.
In order to further understand the method for fast positioning a hard disk under a disk array in this embodiment, an implementation process of the method for fast positioning a hard disk under a disk array in this embodiment is described below with reference to fig. 4.
As shown in fig. 4, the process is performed as follows:
step S1, sending a disk array confirmation command to the bmc.
And the operation and maintenance personnel issue a disk array confirmation instruction to the substrate management controller to inform the disk array group needing to be confirmed, and the substrate management controller receives the disk array confirmation instruction and processes the disk array confirmation instruction.
Step S2, the bmc parses the raid confirmation instruction to obtain the raid group number to be queried.
And the substrate management controller firmware analyzes the disk array confirmation command based on the IPMI command format to acquire the disk array group number to be inquired.
For example, the user needs to light hard disk information of RAID 0: the user sends a command: ipmitool raw 0x3A 0x300x 00; (wherein ipmitool is an open source IPMI command transmission tool), the baseboard management controller analyzes that the field data of the request is 0x00, that is, the hard disk under RAID 0 needs to be lighted.
And step S3, acquiring hard disk information corresponding to the disk array through the disk array card in the baseboard management controller.
After the baseboard management controller analyzes the disk array group number which is requested to be lightened by a user, whether the disk array group exists or not can be inquired through the disk array (RAID) management provided by a disk array (RAID) card, if yes, all hard disk information (serial numbers, positions and the like) under the disk array group is continuously acquired, and the hard disk information is returned to the baseboard management controller.
In step S4, it is determined whether a disk array group exists, and if it does not exist, the process ends, and if it exists, the process continues to step S5.
If the disk array group requested by the operation and maintenance personnel does not exist, ending the task; if the disk array exists, the lighting operation of the hard disk under RAID in step S5 is performed.
And step S5, the baseboard management controller controls the corresponding hard disk lamp to run through the hardware interface.
Specifically, the hard disk lamps corresponding to all the hard disks in the disk array are controlled to be turned on based on the hard disk information, so that all the hard disks in the disk array are positioned, for example, the positioning lamps of all the hard disks in the RAID are turned on first, so that all the hard disks in the RAID are conveniently confirmed, and then, based on a preset sequence, the hard disk lamps are controlled to be sequentially turned on, so that a single hard disk is positioned, for example, the hard disk positioning lamps are sequentially turned on (with the frequency of 1HZ) for 5 times (so that the position of the single hard disk is conveniently confirmed) according to the sequence of the serial numbers of the hard disks.
As can be seen from the above, in the method for quickly positioning a hard disk under a disk array according to the embodiment, the hard disk under the disk array is quickly positioned through the firmware of the baseboard management controller, all hard disks under the same disk array can be displayed, and each hard disk is distinguished and displayed in a lighting manner, so that the maintenance operation time is effectively saved, and the operation and maintenance efficiency is improved.
