above （ How to put the Milky Way Unicorn into U disc ？） mention , Because the domestic server firmware does not support direct configuration RAID, So we need to use storcli This tool is used to operate . Today from RAID Let's briefly introduce the use of this tool in terms of configuration and maintenance , At the same time, it is convenient for everyone to understand RAID The configuration principle of .

First, upload the tool to any directory on the server , And use command chmod +x storcli64 Modify file permissions to executable .

In addition, you can use the command ln -s root/storcli64 usr/bin/storcli To set up soft links , In this way, you can enter... In any directory storcli perform ./ storcli64, Same as the system command .

First Use storcli c0 show Command view RAID Controller information , It contains the topology of the disk 、RAID Information 、 Physical disk configuration status and other information .（ notes ：c namely Controller, controller , That is, the array card ;e namely Enclosure, The attachment , Generally speaking, it is the hard disk backplane “ Hard disk cage ”;s namely Slot, Physical hard disk slot ;v namely Virtual Drive, Virtual hard disk , That is, logical volumes ;d namely Disk Group, Hard disk set ;f namely Foreign configuration file, External array configuration .）

You can also see the temperature of the array card .

The above is the echo when the hard disk slot is empty , stay 1、2 Insert two pieces into the slot 960G Of SSD after , Echo added PD LIST List of physical disks , It is shown as follows ：

Through the command storcli c0/vall show Check it out. RAID Configuration of logical volumes , Currently unconfigured RAID.

Through the command storcli c0/eall/sall show Check it out. c0 All physical slots of the controller and physical disk information in all slots .

Create... For the first time RAID

step 1： If the original disk exists RAID, Need to put RAID Delete

Use storcli c0 vall show Command to view the existing array configuration information , If there is , need Use storcli c0 v0 delete Delete related configuration . If vd contain MBR Or user information data , Need to add force Parameter forced deletion .

step 2： establish RAID

storcli64 Tool creation RAID The specific methods of use are as follows ：

storcli cx add vd r[0|1|5|6|00|10|50|60][Size=<VD1_Sz>,<VD2_Sz>,..|all]

[name=<VDNAME1>,..] drives=e:s|e:s-x|e:s-x,y [PDperArray=x|auto]

[SED] [pdcache=on|off|default][pi] [DimmerSwitch(ds)=default|automatic(auto)|

none|maximum(max)|MaximumWithoutCaching(maxnocache)] [WT|WB|AWB][nora|ra]

[direct|cached] [cachevd]

[Strip=<8|16|32|64|128|256|512|1024>] [AfterVd=X]

[Spares = [e:]s|[e:]s-x|[e:]s-x,y][force]

[Cbsize=0|1|2 Cbmode=0|1|2|3|4|7]

In this case , Yes 1、2 Operate two hard disks to create RAID0 The operation command of is as follows ：

storcli c0 add VD r0 drives=252:0,252:1

You can use this command to directly create RAID0.

For some scenes , May need to use “Size=all” Configuration parameters for , Used to increase all disk space to logical volumes .

You can also use Parameters “name=raid0” To specify the RAID name , Will be in Virtual Drives Of Name Show .

If the configuration is not desired , Can adopt storcli c0/v0 delete force To delete RAID To configure .

Create two more groups RAID, Two pieces of SSD do RAID0,4 block SATA Dish making raid0, And named them separately .

Replace the hard disk , The reconstruction RAID

In actual use , Hard disk failures are common . Due to the limited resources at hand , Is the total 2 block 960G The solid state disk , add 4 block 4T Of SATA disc , So use 3 block SATA Dish making RAID5, in addition 1 Block simulates a new disk to operate .

First create a 3 It's a hard disk RAID5 array .

Through the command storcli c0 /eall /sall show To view physical disk information .

Disk status description ：

UGood（Unconfigured Good, Normal is not configured ）, The hard disk status is normal , But it has not been divided into any logical volumes ;

UBad（Unconfigured Bad, Unconfigured exception ）,UGood There is an unrecoverable error on the hard disk in state ;

Onln（Online, On-line ）, Has been set as a member disk of a virtual hard disk , And it is in the normal online available state ;

Offln（Offline, offline ）, The member disk of a virtual hard disk is offline ;

Missing,Online State of the hard disk is detached RAID Status of the group ;

Rbld（Rebuild, The reconstruction ）, The hard disk is rebuilding data .

Pull out 5 Slot number is 252:4 The hard disk of , After the operation Use command storcli /c0 /vall show To view array information . Find out RAID5 Array status is Dgrd（degreed, Downgrade ）, Near fault , Refer to the previous hardware RAID test （ Hardware RAID Comment on （ On ）、 Hardware RAID Comment on （ Next ））,RAID5 Only one hard disk failure is acceptable , If you pull out another disc , You will enter Failed（ fault ） state .

here , And put the spare 6 Insert hard disk No. 1 as a new disk into 5 Slot No , You can see that the status of the newly inserted disk is Rbld, Recovering data , The reconstruction RAID.

Sure Through the command storcli /c0/e252/sall show rebuild Check it out. rebuild The progress of the , But the time is really long ,RAID No data information , Reconstruction still needs 4 More than half an hour .

Delete external RAID To configure

For example, in the above operation , Because of the operation sequence ,5 The hard disk in slot No. was used as RAID5 member , 6 The hard disk in slot No. was used as RAID0 member , After unplugging, the previous RAID Related configuration , This part of the configuration will lead to the DG Status as F（Foreign）, Unable to add new virtual hard disk .

here , Sure Use command storcli /c0/fall delete Delete the controller c0 All external configuration information for , After deleting DG The state is empty , It can be used normally. .

Replace the hard disk drive separately

The above operation is a direct replacement scenario , If the hard drive is still in use , Need to make Command storcli /c0/e252/s4 set offline take 5 The slot hard disk is set to offline Offline, Reuse command storcli /c0/e252/s4 set missing Set the hard disk drive to missing state , Then you can pull out the original faulty hard disk , Put on a new hard disk .

Introduce the outside RAID To configure

The above mentioned manual hard disk status assignment , For being in ”UBad“ State of the hard disk , Sure Through the command storcli /c0 /e252 /s2 set good Set it to “UGood” state , Convenient for subsequent use .

Once you set it up , You can see the hard disk DG The status is displayed as F, Indicates that there is an external RAID To configure .

have access to command storcli /c0 show View external RAID Details of .

You can try Through the command storcli /c0 /fall import The original RAID Configure recovery .

Again using command storcli /c0 /eall /sall show Check disk status .

Manual reconstruction RAID

As in the previous operation , After the new hard disk is inserted normally, it will be rebuilt automatically RAID, If there is no automatic reconstruction , You need to do the following .

First confirm the disk location , From the status of the hard disk, you can see DG The value of the group is A, From the panel, confirm that the hard disk is on page B Column 、 The first C That's ok , If the hard disk is inserted into 5 Slot No , That's number one 0 Column , The first 2 That's ok , Corresponding The order is ：storcli /c0 /e252 /s4 insert dg=1 array=0 row=2.

Re pass command storcli /c0/e252/s4 start rebuild To manually trigger data reconstruction , You can also use pause、resume Command to pause 、 Continue the reconstruction task .

have access to command storcli64 /c0/e252/s4 show rebuild To see... Alone 4 The slot rebuild speed of progress .

There is no soul , To conform to , Not welcome in the future , It wasn't miscellaneous at that time , I don't love you in the past
