Overview

This article will document the steps required to manage your LSI MegaRAID 9361-8i,9440, 9460, and 9341 RAID Controllers RAID controller in the Unified Extensible Firmware Interface (UEFI) configuration of your Dell system.

Note: The storage devices connected to a LSI MegaRAID 9361-8i RAID,9440, 9460, and 9341 RAID Controllersin the Unified Extensible Firmware Interface (UEFI) configuration are detectable and testable via the ePSA diagnostics of the Dell system where the controller is installed.

Accessing the RAID controller

When you start your system, Slowly tap the F12 key until you see a message: "Entering the one time boot configuration" message in the upper right corner of the screen. Use the arrow keys to select "Device Configuration" option, then press the Enter key.

This will open the system setup UEFI configuration options for your LSI MegaRAID RAID controller. (Figure 1a):

Figure 1a. - Entering the Device Configuration Menu

Note: Accesing the LSI MegaRAID controller may require the BIOS to be set to Legacy mode in some systems. If the system is normally set to UEFI mode, the BIOS can be returned to UEFI after changes are made to the LSI MegaRAID controller.

Creating a RAID volume

Note: Exact matching drives were not available when creating the demonstration, a larger drive was used creating the array and the RAID controller matched the RAID configuration to the smaller drives in the array.

On the LSI MegaRAID RAID controller main configuration screen :

1. Select the "Configuration Management" option and press the Enter key. (Figure 2)

   
   Figure 2. - Selection of Configuration Management Menu
   

2. Select "Create Virtual Drive" and press the Enter key. (Figure 3)
   
   Figure 3. - Selection of Create Virtual Drive Menu
   
3. Use the Up/Down arrows and select the section "Select RAID Level" and press the Enter key. (Figure 4)
   
   Figure 4. - Select RAID Level
   
4. Use the Up/Down arrow and choose Your RAID Configuration and press the Enter key. For the example we will use RAID 1.

   Note: When only 2 drives installed you only the options for RAID 0 and RAID 1 are available. Systems configured with 3 or 4 Drives will also display options for RAID 5 and RAID 10

   
   
5. Use the Up/Down arrow and select "Select Drives" and press the Enter key. (Figure 6)
   
   Figure 6. - Select Drives option
   
6. Use the Up/Down arrow and select a drive that you want in your RAID configuration. (Figure 7)
   
   Figure 7. - Selecting a drive
   
7. Press the Enter key and then use the Up/Down arrow to the "Enable" option and then press the Enter key again. (Figure 8)
   
   Figure 8. - Enabling the drive
   
8. Repeat steps 5, 6, & 7 to add and then enable second drive to the array.
9. Use the Up/Down arrows to select "Apply Changes" and press the Enter key. (Figure 9)
   
   Figure 9. - Applying changes to the array
   
10. The next screen begins a 3-step process to agree to the configuration changes. This is required because applying this change results in 100% data destruction of any data currently on the drives. Select the "Confirm" option, press the Enter key. Then use the Up/Down arrows to select "Enabled" and then press the Enter Key. (Figure 10)
    
    Figure 10. - Applying changes to the array
    
11. Next use the Up/Down arrows and select the section "Yes" and press the Enter key (Figure 11)

13. On the next screen use the Up/Down arrows and select the section for "Save Configuration" and press the Enter Key. (Figure 13)
    
    Figure 13. - Saving the Configuration of the array
    
14. You will see a confirmation screen that the task was successful
15. To save the configuration. You will need to press the F4 key to save and exit out of the RAID configuration menu. Select "Yes" and press the Enter key to confirm. (Figure 14)

Verifying Your RAID Configuration

1. When you start your system, Slowly tap the F12 key until you see a message: "Entering the one time boot configuration" message in the upper right corner of the screen. Use the arrow keys to select "Device Configuration" option, then press the Enter key.

   This will open the system setup UEFI configuration options for your LSI MegaRAID RAID controller. (Figure 15)
   
   Figure 15. - Entering the Device Configuration Menu

2. Use the Up/Down arrow and select the section "Virtual Drive Management" and then press the Enter Key. (Figure 16)
   
   Figure 16. - Selecting the Virtual Drive Management Menu
3. You will now see the available RAID configurations. For our example we only have 1 RAID Arrays setup. At this step we have verified that the raid is optimal and setup for a RAID 1. (Figure 17)

Delete ALL RAID Arrays

This is useful if you need to start from scratch and rebuild your RAIDs back up as needed.

Note: This will remove all MegaRAID configured RAID Arrays on the system

1. When you start your system, Slowly tap the F12 key until you see a message: "Entering the one time boot configuration" message in the upper right corner of the screen. Use the arrow keys to select "Device Configuration" option, then press the Enter key.

   This will open the system setup UEFI configuration options for your LSI MegaRAID RAID controller. (Figure 18)

Delete a Single RAID Array

1. Next you will see a screen that you need to press the enter key for "Ok"
2. If you need to only remove 1 RAID array and keep the other ones, this is the preferred method. Use the Up/Down arrow and select the section "Virtual Drive Management" and then press the Enter Key. (Figure 22)
   
   Figure 22. - Selecting the Virtual Drive Management Menu
   
3. You will now see the available RAID configurations. For our example we only have 1 RAID Arrays setup. If multiple arrays, select the desired one to delete and press the Enter Key (Figure 23)

RAID Consistency Check

This is useful for when the RAID is not working as expected or if you have the operating system on the RAID and it will have issues rebooting. For example, when you have a RAID 1 and the drives become out of sync, they could have issues booting. This is when you would need to run a consistency check to restore functionality

1. On the next menu, use the Up/Down arrow and select the option "Go" and press the Enter key (Figure 25)
