The UEFI HII SAS RAID array configuration interfaces of Lenovo’s various series of servers are different, but the operation steps are the same. There are a few operation modes that are slightly different. Please refer to the description of hard disk selection and confirmation in the above Lenovo knowledge base document for details.

This paper takes thinksystem series server text interface and system X series server UEFI HII array configuration interface as examples.

After entering the SAS RAID array configuration interface, the first step is the dashboard interface, which displays:

“Status” refers to the status of SAS raid card, which is “optimal” under normal circumstances;

“BBU” is the status of the backup unit. If the array card is equipped with battery (BBU) or super capacitor (CVM), it will display “yes”, otherwise it will be “no”;

“Drivers”, that is, the number of hard disks;

“Virtual drives” refers to the status information such as the number of raid volumes.

be careful:Some old SAS raid cards and old version firmware have no dashboard interface, and the key information in the dashboard interface is reflected in the controller management in the main menu.)

Basic operation of Lenovo server to configure array in UEFI HII interface

Page down, in “MegaRAID advanced software options”, the activated functions of the raid card will be displayed, as shown in the following figure:

MegaRAID raid6, namely raid6 function;

MegaRAID RAID5, namely RAID5 function;

MegaRAID safestore, namely data protection function;

MegaRAID fastpath, or SSD enhancement;

MegaRAID cachecade 2.0, SSD cache function;

MegaRAID cachecade Pro 2.0, the advanced SSD caching function.

Note: if the corresponding function is not activated, no item will be displayed here.

Basic operation of Lenovo server to configure array in UEFI HII interface

Entering the main menu from the dashboard is the main interface of RAID configuration. There are five items.

Configuration management is to configure raid settings

“Controller management” is to set up the SAS RAID controller

Virtual drive management is to view and adjust raid settings

“Drive management” is to view and adjust hard disk settings

“Hardware components” is to view and adjust the raid card component settings

Basic operation of Lenovo server to configure array in UEFI HII interface

First confirm whether the hard disk status is available. Enter “drive management” to confirm whether all hard disks appear in the current interface, and the status of hard disks is “unconfigured good”.

be careful:

1. Only the hard disk in unconfigured good state can be configured with raid. The online state indicates that the disk is in an array. The JBOD state indicates that the disk is in single disk through mode. Please refer to the following for the mutual conversion between unconfigured good state and JBOD state“Setting JBOD mode”A section;

2. If the “foreign” mark before unconfigured good indicates that the hard disk has foreign array information, please confirm the source of the hard disk and need to import or clear the information, and then follow the instructions below“Importing and clearing foreign arrays”The first section is for operation;

3. If the hard disk is in “unconfigured bad” state, it indicates that the hard disk is abnormal. If the hard disk capacity identification is normal, or it can be confirmed that it is caused by misoperation, please follow the instructions below“Repair the offline hard disk”Section. If the capacity of the hard disk cannot be identified correctly, it is recommended to re insert and re identify the hard disk. If it is invalid, the hard disk has failed. Please replace it in time.

2、 Create raid0 / 1 / 5 / 6 array

This section describes how to create a set of RAID1 arrays and then a set of RAID5 arrays for 8 hard disks.

Enter the main interface of array card configuration and enter “configuration management”.

Basic operation of Lenovo server to configure array in UEFI HII interface

Then go to “create virtual drive” and create an array.

Basic operation of Lenovo server to configure array in UEFI HII interface

Select RAID level select RAID1.

be careful:RAID levels such as RAID5 require the hardware support of the array card or activation of corresponding functions, and the number of configurable hard disks should meet the minimum requirements, otherwise the corresponding RAID level will not appear.

Basic operation of Lenovo server to configure array in UEFI HII interface

Enter “select drivers” to select the hard disk to join the array.

Basic operation of Lenovo server to configure array in UEFI HII interface

Select 2 hard disks, and then select apply changes.

be careful:

1. Different models have different operation modes for hard disk selection. Please check the instructions for hard disk selection of the corresponding model;

2. Different RAID levels have different requirements for the number of hard disks. For example, RAID1 can only have two hard disks, RAID5 needs at least three hard disks, raid6 needs at least four hard disks, and RAID10 needs at least four even hard disks;

3. If you use SSD to configure the array, you need to change the “select media type” option to “SSD”. Do not add mechanical hard disk and SSD to the same RAID array;

4. Since the default value of “select interface type” is “both”, you can see SAS interface hard disk and SATA interface hard disk when selecting hard disk, but do not select SAS interface hard disk and SATA interface hard disk in the same RAID array.

Basic operation of Lenovo server to configure array in UEFI HII interface

Inform that the operation has been carried out successfully, OK to continue.

Basic operation of Lenovo server to configure array in UEFI HII interface

Back to the create array interface, you can modify the “virtual drive size” to adjust the raid volume size. If the “select drives” configuration in the previous step is wrong, the value will not be displayed here and cannot be modified; if you want to volume the array, press enter here and enter the required size. See“Creating a RAID5 array of volumes”A section.

For the newly established array, it is recommended to set “disable background initialization” to “yes” and “default initialization” to “fast” for fast initialization to clear the data on the array and hard disk.

be careful:If you are trying to repair a mistakenly deleted array (volume), leave “default initialization” as the default “no”.

be careful:If “default initialization” is set to “full”, the slow full initialization will be performed. The array may not be used during the slow initialization process, so it is not recommended to select this option.

Other items generally do not need to be adjusted. To adjust other items, read below“Modify parameters such as array cache policy”And according to the actual needs of the operation.

be careful:Some parameters, such as strip size, cannot be modified after the array is created.

Select save configuration to save the RAID configuration.

Basic operation of Lenovo server to configure array in UEFI HII interface

After “save configuration” is selected, a confirmation operation will appear, and the prompt will erase the existing data on the hard disk. After “save configuration” is confirmed, select “yes” to continue.

be careful:The confirmation operation mode of different models is different. Please check the description of confirmation operation for the corresponding model.Basic operation of Lenovo server to configure array in UEFI HII interface

Prompt that the operation has been successfully executed and “OK” is completed.

3、 Create RAID10 array

This section describes how to create a RAID10 array with eight hard disks.

Please read the previous section first“Create raid0 / 1 / 5 / 6 array”This section only introduces the differences from the previous section.

Select RAID level select RAID10.

be careful:RAID10 requires at least four hard disks. If the number of available hard disks does not meet the requirements, raid 10 option is not optional.

Basic operation of Lenovo server to configure array in UEFI HII interface

Select select drivers on the line next to span 1.

Basic operation of Lenovo server to configure array in UEFI HII interface

5、 Set up hot spare and manually replace the failed hard disk reconstruction array

This section describesSet hot spareandRemove hot spare

The operation of setting hot spare is to set hot spare when the array is in normal state, and to manually rebuild the array when the array is in degraded state.

In the main interface of array card configuration, enter drive management and select a hard disk in unconfigured good status.

Basic operation of Lenovo server to configure array in UEFI HII interface

In “operation”, select “assign global hot spare drive” to set global hot spare disk or “assign dedicated hot spare disk” to set dedicated hot spare disk.

Global hot standby means that when any array on the array card is degraded, the disk will be rebuilt; dedicated hot standby will assign the disk to a specific array, and only when a specific array is degraded, the disk will be rebuilt. When there are multiple arrays or different types of hard disks on the array card, it is recommended to set up a dedicated hot standby.

Basic operation of Lenovo server to configure array in UEFI HII interface

Then press enter on the “go” that appears on the next line.

Basic operation of Lenovo server to configure array in UEFI HII interface

If it is set to dedicated hot standby, you will be asked to select the array for hot standby and press “OK” to continue.

Basic operation of Lenovo server to configure array in UEFI HII interface

If it is set to global hot standby, you will be prompted that there may be incompatibility. Confirm and continue.

Basic operation of Lenovo server to configure array in UEFI HII interface

Inform the operator that the operation is successfully completed and “OK” continues.

Basic operation of Lenovo server to configure array in UEFI HII interface

Return to the main interface of array card configuration, and then enter “drive management” to see that the disk is in “hot spare” state. If the disk is assigned to an array in “degrade” state, it will be rebuilt.

You will be prompted to confirm the removal of the hot spare. Confirm at “” and select “yes”. Then you will be prompted that the operation has been successfully completed and “OK” will continue.

Basic operation of Lenovo server to configure array in UEFI HII interface

6、 Reinitialize the array

If you do not choose to perform initialization operation when creating an array, or you need to clear the data in the existing array, you can initialize the array in the main interface of array card configuration “virtual drive management”

Select the virtual drive to initialize.

Basic operation of Lenovo server to configure array in UEFI HII interface

In the “operation” option, select “fast initialization” to perform fast initialization.

“Slow initialization” means slow initialization, which is the same as setting “default initialization” to “full” when creating an array. Both of them use specific data to override the entire array. Full initialization will thoroughly detect the condition of the hard disk and erase all data, so it takes a long time. In this process, the array may not be used normally. Generally, it is only used when the array or hard disk is abnormal.

Basic operation of Lenovo server to configure array in UEFI HII interface

Then press enter on the “go” that appears on the next line.

Basic operation of Lenovo server to configure array in UEFI HII interface

It will prompt that the data on the array will be erased. Confirm to continue. Fast initialization is usually completed in seconds, while slow initialization may take several hours. The operation progress will be displayed in the “virtual drive management” interface.

Basic operation of Lenovo server to configure array in UEFI HII interface

7、 Modify parameters such as array cache policy

For existing arrays and volumes, you can modify parameters such as array cache policy in virtual drive management.

For example, after the ServeRAID m5210 array card for system X series servers is equipped with a cache module or a flash + Super Capacitor Kit, parameters such as array cache policy can be modified in “virtual drive management” to improve performance.

Select the virtual drive where you want to modify the cache policy.

Basic operation of Lenovo server to configure array in UEFI HII interface

Go to the “advanced…” page.

Basic operation of Lenovo server to configure array in UEFI HII interface

Modify “default write cache policy” to “write back”, and adjust the write cache policy to write back mode.

Basic operation of Lenovo server to configure array in UEFI HII interface

You can also modify other parameters on this page. Some parameters can only be modified in theCreating arraysCannot be modified later.

“Segment size” (that is, the “strip size” when creating an array), the data stripe size, which is used to adjust the size of data block cells distributed on each hard disk. If the array is used for storage, it can be increased; if it is used for database, it can be decreased. Adjusting this may affect array performance. If there are no special requirements, there is no need to adjust this item. This item cannot be modified after the array is created.

“Access” (that is, the “access policy” when creating the array), access policy. When set to “read / write”, the volume can be read and written, which is the default. When set to “read only”, this volume can only be read but not written. When set to “blocked”, this volume is not accessible regardless of read or write.

“Default write cache policy” (that is, the “write policy” at the time of array creation). The write cache policy can be modified only when the array card is equipped with cache, otherwise it is fixed to “write through”. When it is set to “write through”, the data will not be written back until it is finally written to the hard disk. When the array card is not equipped with cache, this is the default value. When it is set to “write back” and the array card is equipped with a backup unit (battery), the data is written back to the cache of the array card. This mode will improve the performance of the array. When the array card is equipped with a cache, this is the default value. However, if the array card is not equipped with a backup unit, it will operate in “write through” mode. When it is set to “always write back”, the write back mode is turned on regardless of whether the cache has a backup unit (battery). This mode has a great risk of data loss when the server encounters an unexpected power failure. Please choose it carefully.

“Disable background initialization (BGI)” (i.e. “disable background initialization” when creating an array), background initialization is disabled, and the default value is “no” (i.e. background initialization is not disabled). After creating a new array / volume, the array card will initialize the array / volume in the background to check the consistency of hard disk and data. Background initialization takes a long time, which may affect the performance of the hard disk. Therefore, it is recommended to disable background initialization when foreground initialization (fast initialization or full initialization) is in progress.

“Read cache policy” (that is, the “read policy” when creating an array). The read cache policy can only be modified when the array card is equipped with cache, otherwise it is fixed as “no read ahead”. When it is set to “no read ahead”, the array card will not perform read ahead operation, which is the default setting for the array of SSD. When it is set to “read ahead”, the array card will automatically read the sequential data requested by the host into the cache in advance, which can improve the continuous reading performance to a certain extent, but does not significantly improve the random reading performance. This is the default setting for the array of mechanical hard disk.

“Drive cache”, hard disk cache policy. When set to “disable”, the hard disk cache is disabled, which is the default setting. When set to enable, hard disk caching is enabled. When it is set to “unchanged”, the hard disk cache policy is not changed.

“Input / out (I / O)” (that is, the “I / O policy” when the array is created). The IO policy can only be modified when the array card is equipped with cache, otherwise it is fixed to “direct I / O”. When set to “direct I / O”, read operation data is not buffered in the cache, which is the default. When set to “cached I / O”, read operation data is buffered in the cache.

“Simulation type”, simulation mode. Used to set the sector format of the array / volume composed of advanced format / AF hard disks. The default is “default”. If you want to force the advanced format hard disk to simulate the traditional 512 byte / sector format, you can set it to “force”.

After modifying the parameters, select “apply changes” and confirm.

Note:““Current write cache policy” is the current cache policy. Parameter changes such as cache policy need to restart the server to take effect.

Basic operation of Lenovo server to configure array in UEFI HII interface

8、 Configure cachecade

Cachecade is an optional advanced feature of SAS raid card, which enables SSD to speed up existing arrays and volumes. To confirm that the cachecade feature is enabled, return to“DashboardInterface.

Note: the thinksystem series servers do not support the cachecade function.

System X series servers have level requirements for SSD used for cachecade, and require SATA SSD with minimum enterprise value level. Seehttps://support.lenovo.com/solutions/migr-5094754

Note: refer to thehttps://lenovopress.comThe product guide document on.

When the SAS raid card and SSD meet the above requirements, “create cachecade virtual drive” item will appear in the “configuration management” interface.

Basic operation of Lenovo server to configure array in UEFI HII interface

Operation and implementation of creating cachecade volumeCreating a raid volumeSimilarly, set the “RAID level” and “write cache policy” of the cachecade, and select the SSD to be configured as cachecade cache.

Basic operation of Lenovo server to configure array in UEFI HII interface

After checking, select “create cachecade virtual drive” to save the settings. Then you will be prompted that the operation is complete, and select “OK” to continue.

Basic operation of Lenovo server to configure array in UEFI HII interface

Return to “main menu” and enter “virtual drive management” to view the newly created cachecade volume.

Basic operation of Lenovo server to configure array in UEFI HII interface

Next, use cachecade volume acceleration for existing arrays / volumes. Enter the existing array / volume and select enable SSD caching in operation.

Basic operation of Lenovo server to configure array in UEFI HII interface

Select the “go” that appears on the next line.

Basic operation of Lenovo server to configure array in UEFI HII interface

There will be confirmation operation. After confirmation, select Yes and OK to continue.

Basic operation of Lenovo server to configure array in UEFI HII interface

After the operation, you can view the cachecade status in “advanced…” of the virtual drive.

“SSD caching” as “enable” indicates that SSD cache acceleration is enabled, “cachecade type” as “read and write” indicates that both read and write operations will be accelerated.

Note: some old SAS raid cards and cachecade functions only support read acceleration, that is, “cachecade type” is “read only”.

Basic operation of Lenovo server to configure array in UEFI HII interface

9、 Setting JBOD mode

If you do not want to configure the array and directly use the hard disk independently, you can set the hard disk to JBOD, that is, single disk through mode.

First, confirm whether the current array card supports JBOD mode. Enter “controller management” in the main interface of array card configuration, and then enter “advanced controller properties” to view the status of “JBOD mode” project. If it is in “enabled” status, it means support.

Basic operation of Lenovo server to configure array in UEFI HII interface

If the array cards such as ServeRAID m5110 (E) and m5210 (E) used for system X series servers are equipped with cache, this item is “disabled” and cannot be modified directly, so JBOD mode is not supported. To enable the JBOD mode of the m5110 (E) and m5210 (E) array cards, the cache module on the array card must be removed before it can be turned on. Reference《Remove the cache module of the ServeRAID m5210 array card to enable JBOD mode》(repository number: 154463).

The setting of “JBOD mode” item of some models of SAS raid card and some firmware versions can be changed manually. After applying the change, “apply change” will prompt to restart the server to switch the working mode of SAS raid card. After the “JBOD mode” is changed from “disabled” to “enabled” switching mode, the array card will be reduced to IMR mode, and the advanced functions including RAID5 will not be available, so please make sure to confirm before performing the operation to prevent data loss.

Basic operation of Lenovo server to configure array in UEFI HII interface

The hard disk in “unconfigured good” state and “JBOD” state can be converted to each other at will. Select the hard disk in “unconfigured good” state in “drive management” interface, and select “make JBOD” in “operation”.

Basic operation of Lenovo server to configure array in UEFI HII interface

Then press enter on “go” in the next line and confirm.

Basic operation of Lenovo server to configure array in UEFI HII interface

If you want to set boot from this disk, you need to select this disk in “select boot device” in “controller management”.

Basic operation of Lenovo server to configure array in UEFI HII interface

After setting the disk as boot, the disk will be added with “bootable” status in “drive management”.

Basic operation of Lenovo server to configure array in UEFI HII interface

The steps to reset the “JBOD” state to the “unconfigured good” state are similar to the above, and select “make unconfigured good” in “operation”.

Basic operation of Lenovo server to configure array in UEFI HII interface

Then press enter on “go” in the next line and confirm.

Basic operation of Lenovo server to configure array in UEFI HII interface

The conversion between the “unconfigured good” and “JBOD” states of hard disks can also be operated in the “configuration management” interface. There are “make unconfigured good” and “make JBOD” options respectively, which can batch convert multiple hard disks at one time. The operation is similar to the steps of selecting hard disks when creating arrays, and will not be repeated here.

10、 Importing and clearing foreign arrays

This section describes how to import and clear array information from hard disks on other servers.

be careful:The operation of importing and clearing foreign array information does not affect the existing array configuration of the machine.

Enter “drive management” to check whether all hard disks have been recognized, and the status is “(foreign), unconfigured good”.

be careful:If the status of the hard disk to be imported or cleared is “unconfigured bad”, please refer to the next section“Repair the offline hard disk”, change the status of the hard disk to “(foreign), unconfigured good” before operation.

Basic operation of Lenovo server to configure array in UEFI HII interface

Return to the main interface of array card configuration, enter “configuration management”, and then enter “manage foreign configuration”.

Basic operation of Lenovo server to configure array in UEFI HII interface

To import foreign array information, select preview foreign configuration; to clear foreign array information, select“Clear Foreign Configuration“。

Basic operation of Lenovo server to configure array in UEFI HII interface

After selecting “preview foreign configuration”, confirm the hard disk and array information, and then select “import foreign configuration”.

be careful:The premise of importing foreign array information is that the native SAS raid card supports the necessary RAID level, and the foreign array information must be complete, otherwise “not importable” will be prompted.

Basic operation of Lenovo server to configure array in UEFI HII interface

Next, the prompt will import the foreign array information on the hard disk into the existing configuration, and confirm to continue.

Basic operation of Lenovo server to configure array in UEFI HII interface

Enter “drive management” again, and the status of the hard disk has changed to “online”.

Basic operation of Lenovo server to configure array in UEFI HII interface

11、 Repair the offline hard disk

This section describes how to repair the single hard disk offline caused by wrong plug-in during server operation.

If the hard disk is disconnected, the yellow light will be on the hard disk bracket (whether the normal hard disk is disconnected by mistake or the hard disk is faulty). At this time, the non raid0 array will be in the “degraded” or “partial degraded” state.

be careful:If two or more hard disks are offline, it means that the array has collapsed. It is recommended to seek professional data recovery for repair. Only when the data is not important, you can refer to this section for operation.

Basic operation of Lenovo server to configure array in UEFI HII interface

Enter “drive management” to check, and the status of the hard disk that has been wrongly inserted and unplugged is “unconfigured bad”. Enter this hard disk.

15、 Array online expansion and array level online migration

When you need to add a hard disk to the array or convert the array to other RAID levels, but it is inconvenient to delete the existing array, you can use the online migration and online expansion of the array.

be careful:

1. This operation has great risks to the array and data. Please consider carefully and back up the data before operation;

2. It needs the array card to support the online expansion and migration of the array, and the RAID level after the migration can be implemented. It also needs to comply with the corresponding RAID configuration rules.

3. After the expansion and migration operation starts, the operation cannot be terminated and takes a long time (depending on the array capacity and disk type). Please do not shut down or power down in the middle of the operation.

This section describes how to add a hard disk to a group of RAID1 arrays and migrate them to RAID5.

In “virtual drive management”, select the virtual drive that needs to be expanded and migrated.

Basic operation of Lenovo server to configure array in UEFI HII interface

Press enter on the “operation” item and select “reconfigure virtual drive” to reconfigure the virtual disk.

Basic operation of Lenovo server to configure array in UEFI HII interface

Press enter on the “go” that appears on the next line to continue.

Basic operation of Lenovo server to configure array in UEFI HII interface

In the interface of “reconfigure virtual drive”, select RAID5 on the project of “new RAID level”, that is, migrate to RAID5. If the RAID level is not changed and only the hard disk is added, the original RAID level will remain unchanged.

16、 Array card firmware refresh

SAS raid card has many ways to refresh firmware. This section describes the operation steps of refreshing in HII.

Refreshing microcode can solve some known problems. When the array card fails to lock the security mode, you can try to refresh the firmware to unlock it.

be careful:

1. Firmware refresh operation has certain risks. Do not refresh firmware arbitrarily if it is unnecessary;

2. Firmware refresh generally does not affect the existing array and data, but it is recommended to make a backup before operation.

The array card firmware can be obtained from the product support website of Lenovo data center

Lenovo (China) data center product support website:http://support.lenovo.com.cn/EsWeb/

Lenovo (global) data center product support website:https://datacentersupport.lenovo.com/

IBM Download Center:https://www-945.ibm.com/support/fixcentral

be careful:Before downloading, please check the instruction document (. Txt) and update instruction (. CHG) to check the application scope and precautions of microcode.

After downloading to the firmware package file, decompress the firmware package (. Zip package and. Exe executable file can be directly decompressed), and find out the. ROM file.

be careful:For array cards such as ServeRAID m5210, there may be two. ROM files in the firmware package. Please check the “CTLR” in them- info.txt “Determine the ROM file correspondence.

Copy the. ROM file to the U disk which has been formatted as FAT32 file system. It is suggested to set a short English volume label to the U disk for easy identification. Then safely remove the U disk and plug it into the USB interface of the server.

Go back to the server and enter “firmware update” in “dashboard”.

be careful:Old model SAS raid card and old version firmware “firmware update” are in “controller management”.

Basic operation of Lenovo server to configure array in UEFI HII interface

Then, select the U disk (volume label) with. ROM firmware file in “select file system” of “controller firmware update” interface.

be careful:Due to the compatibility problem of USB flash disk, if the USB flash disk is confirmed to be FAT32 file system but cannot be recognized, please try to replace another USB flash disk.

Basic operation of Lenovo server to configure array in UEFI HII interface

The array card will automatically recognize the firmware file. If there are multiple. ROM files in the USB flash disk, please manually select the correct file from “select image”. Then select Update and press enter.

Basic operation of Lenovo server to configure array in UEFI HII interface

The array card will prompt the existing firmware version (“current firmware version”) and the new firmware version (“selected firmware version”). After checking, confirm with “” and select “yes” to refresh the firmware.

be careful:

1. Firmware can be upgraded or degraded. Before downgrading or upgrading across larger versions, please read the release notes to confirm whether there are restrictions;

2. Firmware update may take several minutes. During this period, do not stop operation, shut down or power off, otherwise the hardware may be damaged.
