Abstract
The invention discloses a test method for supporting hot plugging of an NVME hard disk in linux, and relates to a hard disk test technology. The hot plugging of NVME is supported by controlling power of the NVME hard disk through a command. The method mainly comprises the steps of 1) modifying a grub file of rhel7.0/6.6; 2) searching for the NVME hard disk; and 3) setting the power of the NVME hard disk to be 0, thereby realizing the hot plugging. According to the method, the hot-plugging replacement of the NVME hard disk is realized without influencing a running condition of a server; and the method is simple and easy, is convenient in operation, can replace the NVME hard disk which is damaged or full in storage, and improves the stability of the server.
Description
Technical field
The present invention relates to hard disk test technology, specifically a kind of support that NVME hard disk is hot-swappable under linux
Method of testing.
Background technology
With the continuous development of IT field technology, conventional informationization service and increasingly powerful cloud computing service are to service
The performance requirement more and more higher of device.NVME hard disk presents as data medium, the entirety that its performance directly affects server.NVME
Hard disk has the advantage that：1st, lower time delay：NVME has simplified method of calling, does not need to read register during execution order；
2nd, higher transmission performance：Enterprise-level PCIe SSD high-end at present, its queue depth may reach 128, even 256
Highest IOPS performance can have been given play to；And under NVMe standard, maximum queue depth is up to 64000；In addition the queue of NVMe
Quantity also from the 1 of AHCI, improves 64000；3rd, lower power consumption control：Batch processing under Shell script and Windows/Dos
Similar, it is placed in advance in in a file with all kinds of orders, a program file of convenient disposable execution, facilitate keeper to enter
Row setting or management；It is more powerful than the batch processing under Windows, than the program efficiency with other programs editor
Higher.
But during server runs, NVME hard disk corruptions often occur, or data storage is full, need more
Change the phenomenon of NVME hard disk.NVME hard disk is different from common hard disk, does not support hot-swappable.The hot-swappable blue screen that can cause system
Or restart, as server hardware supplier, need in product development to put into the property that great amount of cost removes development NVME hard disk
Can test job.Accordingly, it would be desirable to design a kind of method, under the running status not affecting server, support carries out hot-swappable
NVME hard disk test.
Content of the invention
The present invention is directed to demand and the weak point of current technology development, provides a kind of support NVME hard disk under linux
Hot-swappable method of testing.
A kind of method of testing supporting NVME hard disk hot-swappable under linux of the present invention, solves above-mentioned technical problem
Using technical scheme as follows：A kind of described method of testing supporting NVME hard disk hot-swappable under linux, by order control
The power of NVME hard disk, to support that NVME's is hot-swappable, mainly comprises the steps：1）The grub literary composition of modification rhel7.0/6.6
Part, 2）Lookup NVME hard disk, 3）By the power of NVME hard disk is set to 0, to realize hot-swappable.
Preferably, described step 1）In the grub file of modification rhel7.0/6.6, under grub file respective guide menu
The boot parameter of kernel at increase " pci=pcie_bus_perf ", modification finishes and preserving and exiting, and restarts OS.
Preferably, described step 2) search NVME hard disk, run order in linux system：cd /sys/bus/pci/
Slots, in execution ls, shows all of hard disk digital, by order：Cat n/power implementing result is 1, is expressed as
NVME hard disk, n represents described hard disk digital.
Preferably, described step 3）By the power of NVME hard disk is set to 0, to realize hot-swappable, main process is such as
Under：
1）echo 0 >/ sys/bus/pci/slots/n/power, the power making NVME hard disk is 0；
2）After upper bar order is finished and waits the 2-3 second, normally extract corresponding NVME hard disk；
3）Wait and again this hard disk being plugged for 10 seconds about, wait the power supply indicator on hard disk to light；
4）echo 1 >/ sys/bus/pci/slots/n/power, the power making NVME hard disk is 1；
5）Now, system has identified that the nvme disk of new insertion, and this disk normally can be read and write.
A kind of method of testing supporting that NVME hard disk is hot-swappable under linux of the present invention compared with prior art has
Beneficial effect be：The present invention under the operation conditions not affecting server, can control the power of NVME hard disk by order
To realize the support to NVME hard disk it is achieved that the hot-swappable replacing of NVME hard disk, and the method is simple, operation side
Just, can change to damaging or storing full NVME hard disk, improve the stability of server.
Specific embodiment
For making the object, technical solutions and advantages of the present invention become more apparent, below in conjunction with specific embodiment, to this
A kind of bright described method of testing supporting that NVME hard disk is hot-swappable under linux further describes.
Embodiment：
Described in the present embodiment, server is done with the automated testing method of AC switching on and shutting down, NVME hard disk is controlled by order
Power, to support that NVME's is hot-swappable, mainly comprises the steps：1）The grub file of modification rhel7.0/6.6,2）Search
NVME hard disk, 3）By the power of NVME hard disk is set to 0, to realize hot-swappable.
Described step 1）In the grub file of modification rhel7.0/6.6, rhel7.0：/boot/grub2/grub.cfg ；
rhel 6.6：/boot/grub/grub.conf；The step for refer to, the kernel under grub file respective guide menu
Boot parameter at increase " pci=pcie_bus_perf ", modification finishes and preserving and exiting, and restarts OS.RHEL, i.e. Red Hat
The abbreviation of Enterprise Linux, is the linux system of Red Hat company.Rhel7.0/6.6 is a linux system version.
Described step 2) search NVME hard disk, it is primarily referred to as, run order in linux system：cd /sys/bus/pci/
Slots, in execution ls, shows all of hard disk digital (0 0-1 0-10 0-2 23,24,25,26 etc.), by order：cat
N/power implementing result is 1, is expressed as NVME hard disk, and what n represented is exactly hard disk digital above.
Described step 3）By the power of NVME hard disk is set to 0, to realize hot-swappable, main process is as follows：
1）echo 0 > /sys/bus/pci/slots/n/power n:The NVME hard disk number that expression is above found, makes NVME hard
The power of disk is 0；
2）After upper bar order is finished and waits the 2-3 second, you can normally extract corresponding NVME hard disk；
3）Wait and again this hard disk being plugged for 10 seconds about, wait the power supply indicator on hard disk to light；
4）echo 1 >It is 1 that/sys/bus/pci/slots/n/power makes the power of NVME hard disk；
5）Now, system has identified that the nvme disk of new insertion, and this disk normally can be read and write.
Above-mentioned specific embodiment is only the concrete case of the present invention, and the scope of patent protection of the present invention includes but is not limited to
Above-mentioned specific embodiment, any person of an ordinary skill in the technical field that meet claims of the present invention and any
The suitable change or replacement that it is done, all should fall into the scope of patent protection of the present invention.
