The terms referred to herein are explained as follows:
the magnetic disk is a memory for storing data by using a magnetic recording technology, is a main storage medium of a computer, can store a large amount of binary data, and can keep the data from losing even after power is off. The Disk used in early computers was a Floppy Disk (Floppy Disk), and the Disk commonly used today was a Hard Disk (Hard Disk).
Disk array mode is a technique for combining multiple independent hard disks (physical hard disks) in different ways to form a hard disk group (logical hard disk), thereby providing higher storage performance than a single hard disk and providing data backup. It mainly includes nine modes, denominated by numerals, RAID0, RAID1 through RAID 7, and RAID 0+1, with the four modes RAID0, RAID1, RAID5, and RAID 0+1 being the most common.
Fig. 1 schematically illustrates a flowchart of a disk array pattern query method according to an embodiment of the present disclosure.
As shown in fig. 1, a disk array mode query method provided by the present disclosure may include operations S110 to S120.
In operation S110, a disk device name queried by a user is received.
In the embodiment of the present disclosure, a correspondence relationship between a disk array mode and a disk device name may be established in advance, and then, the server may accept a user inquiry to specify a geomagnetic disk device name.
In operation S120, a disk array pattern corresponding to the disk device name queried by the user is queried according to the correspondence relationship between the disk device name and the disk array pattern.
According to the embodiment of the disclosure, after the correspondence between the disk device names and the disk array modes is established, the disk device names and the disk array modes of each disk device are stored in an associated mode, an instruction containing the disk device names is input through a software or web interface or an operating system command interface, the disk array mode of the designated disk device is queried, the directional query of the disk array mode of the disk device is realized, and a user only obtains the disk array mode of the disk device to be understood, so that the method is convenient and quick.
Optionally, the method may be automatically executed after a preset instruction is input by the user on the operating system, or may be executed by clicking a webpage or a button on software by the user, where the triggering manner is not unique and is not limited herein.
In the present disclosure, a method is described using a server including a disk device as a carrier, and one or more servers may be used. It will be appreciated that the device to which the method is applicable is not limited to a server but may be a smart phone, tablet, laptop and desktop computer, etc.
In the embodiment of the present disclosure, the establishment of the correspondence between the disk array mode and the disk device name includes steps S130 to S150.
In operation S130, a common identifier and a disk array pattern of each disk device on the server are acquired.
It should be noted that, the existence of the common identifier is not generally known to those skilled in the art, and the present disclosure uses an identifier that corresponds to a disk array mode and a disk device name on an operating system together to establish a connection between the two, so as to determine a disk array mode used by a disk device on the operating system.
According to an embodiment of the present disclosure, the common identifier and the disk array mode of each disk device may be acquired by executing a preset identifier acquisition instruction and mode acquisition instruction, and operations S131 to S133 may be included.
In operation S131, a preset code number corresponding to each disk device on the server is obtained.
Operation S131 includes two steps S1311 to S1312.
S1311, executing a preset disk device number acquisition instruction to acquire the total number of disk devices on the server.
According to the embodiment of the disclosure, when a user needs to know the disk array mode of each disk device, the total number N of all the disk devices on the server is obtained, and the total number of the disk devices can be obtained through a command, for example, by using a disk array management tool Storcli, executing the instruction "/opt/MegaRAID/starch 64/c0 show all|grep 'Virtual Drives'", after executing the command, the result is displayed through a window, and a part of the display result equal to the total number of the disk devices on the operating system is extracted. Storcli is only an optional disk array management tool, and other disk array management tools may be used to obtain corresponding information, and such tools will be used in the following steps, which will not be described further.
Alternatively, the window displaying the echo result may be a web page, a system window of an operating system, a visualized client software window, a terminal screen using Xshell, or the like.
S1312, obtaining preset coding serial numbers of all the magnetic disk devices based on the total number of the magnetic disk devices.
When each magnetic disk device is configured in the server, a preset coding sequence number is obtained for distinguishing the respective identities, and the preset coding sequence number of each magnetic disk device can be deduced to be 0 to N-1 in sequence because of the total number N of the obtained magnetic disk devices.
In operation S132, a preset mode acquisition instruction is sequentially executed on each disk device according to the preset code number, so as to acquire a disk array mode of each disk device.
The preset code sequence numbers of the disk devices correspond to the disk array modes of the disk devices, so that the disk array modes of the disk devices can be obtained by obtaining the preset code sequence numbers of the disk devices.
Alternatively, the mode acquisition instruction may be: the method comprises the steps of/opt/MegaRAID/garcili 64/c0/v { i } show all|grep RAID, wherein i represents a preset coding sequence number of the disk device, i represents a value of i, and the instruction means that a disk array mode of the disk device i is queried through a disk array management tool garcili. For example, when the preset encoding sequence number of the magnetic disk device is i=1, the corresponding mode acquisition instruction is: and (3) the opt/MegaRAID/store li64/c0/v1show all|grep RAID is used for inquiring the disk array mode of the disk device with the preset code number of 1, acquiring a echo after executing the command, and extracting a part of the echo representing the disk device array mode.
In operation S133, a preset identifier acquisition instruction is executed for each disk device according to the preset encoding sequence number, and a common identifier of each disk device is acquired.
Since the preset code serial numbers of the magnetic disk devices also correspond to the common identifiers, the common identifiers of the magnetic disk devices can be obtained by obtaining the preset code serial numbers of the magnetic disk devices.
Alternatively, the identifier acquisition instruction may be: the method comprises the steps of (1) carrying out an instruction by using a disk array management tool (garcali) to inquire a common identifier of a disk device (i), acquiring a back display after executing the instruction, and extracting a part of the common identifier of the back display, wherein i represents a preset coding sequence number of the disk device, and { i } represents a value of i.
According to the embodiment of the disclosure, after the instruction is executed, the result may be displayed back to the user through the window, and at the same time, the common identifier and the corresponding disk array mode are stored.
In operation S140, the disk device names of the respective disk devices are acquired by the respective common identifiers.
According to an embodiment of the present disclosure, the corresponding disk device name may be acquired by executing a preset name acquisition instruction, and operations S121 to S122 may be specifically included.
In operation S141, a preset name acquisition instruction is executed to acquire a disk device name corresponding to the common identifier.
According to the embodiments of the present disclosure, by using the correspondence relationship existing between the common identifier of each disk device and the disk device name of that disk device, the disk device name can be queried through the common identifier. The name acquisition instruction may be: "ls-al/dev/disk/by-id|grep wwn-0x { common identifier }" where { common identifier } represents the value of the common identifier, after execution of the command, the echo is obtained and the portion representing the disk device name on the operating system is extracted.
Alternatively, the common identifier is a character string such as "67000585bb657cc723a3f4e807e5 feea".
The preset mode acquisition instruction, the identifier acquisition instruction, the disk equipment quantity acquisition instruction and the name acquisition instruction are all preset instructions of the server.
Alternatively, the mode obtaining instruction, the identifier obtaining instruction, the disk device number obtaining instruction, and the name obtaining instruction may be a storage path for storing the disk array mode, the common identifier, the disk device number, and the disk device name for the server system.
In operation S142, the disk device names of the respective disk devices and the corresponding disk array patterns are stored.
In operation S150, a correspondence relationship between the disk device names and the disk array patterns is established.
According to the embodiment of the disclosure, after the disk array mode and the disk device name of the disk device are acquired, the disk array mode and the disk device name are correspondingly associated in the form of key value pairs, tables, labels and the like, so that the disk array mode and the disk device name are displayed for a user to check in pairs, the user can intuitively know the disk array mode of each disk device, and each disk device is more reasonably utilized.
Optionally, the method may further include operation S160.
In operation S161, the disk device name and the corresponding disk array mode are output to the display interface for viewing by the user.
According to the embodiment of the present disclosure, after the operation S130 is performed, the disk device names of all the disk devices on the server and the disk array modes corresponding to the disk device names may be displayed to the user through the display interface, so that the user may acquire the disk array modes of each disk device in real time; after the disk array name queried by the user is queried, the queried result is also displayed to the user for viewing.
Alternatively, the display interface may be software, a web page interface, an operating system command interface, a terminal screen using Xshell, or the like.
The following is an exemplary description with reference to specific examples.
In this example, since the server cannot display the disk array mode of the disk device and its disk device name to the user, in order to enable the user to intuitively check which disk array mode is used by each disk device, the disk device name and the disk array mode of the corresponding disk device may be associated with each other by using the common identifier of the disk device, and displayed to the user. Taking a server including three disk devices with the name sda, sdb, sdc as an example, the corresponding disk array modes are RAID0, RAID1 and RAID5 respectively. Firstly, a query instruction is executed through a disk array management tool Storcli, and the total number of all disk devices on a server is obtained, so that the number of the disk devices is 3.
Then, according to the total number of the disk devices, the preset coding sequence numbers of the disk devices are deduced, the disk devices are respectively marked as 0, 1 and 2, according to the preset coding sequence number sequence, a disk array management tool garcili respectively executes an identifier acquisition instruction and a mode acquisition instruction for the corresponding disk devices to acquire a common identifier and a disk array mode of the disk devices, and taking the disk device 1 as an example to acquire the common identifier and the disk array mode of the disk devices, wherein the disk array mode is RAID1.
And secondly, executing a name acquisition instruction through a disk array management tool Storcli according to the common identifier of the acquired disk device to acquire the disk device name of the disk device. Taking disk device 0 as an example, its disk device name "sda" is acquired by the common identifier.
And finally, establishing a corresponding relation between the names of the disk devices and the disk array modes, such as establishing key value pair storage for "sda" and "RAID0", "sdb" and "RAID1", "sdc" and "RAID5", and displaying the key value pair storage through an interface for the user to review.
According to the disk array mode query method provided by the disclosure, the disk array mode of the disk device and the name of the disk device correspond to one common identifier, after the disk array mode of the disk device and the common identifier are acquired, the name of the disk device is acquired by the common identifier, the connection between the disk array mode and the name of the disk device is established, the names of all the disk devices on the server and the disk array mode thereof can be displayed to a user for viewing through an interface by performing one-time method (the user operation can be simplified to be a simple operation such as pressing a key or inputting an instruction), so that the user can know the disk array mode of each disk device on the server, the user can know which disk array mode is used by each disk device on the server, the disk resources can be utilized more reasonably, and the problems of resource waste, unstable system caused by misuse of disks and the like are avoided.
