I have a dell R730xd
server with an iDrac8 with a PERC H730P mini Raid Controller with 2GB of cache.
My plan is to set up a
raid 1 for the 2x 2.5" drives and a raid 6 for the 4x 3.5" drives.
Convert the drives to Raid
After logging into the
iDrac8 web page open up Overview à Storage à Physical Disk
Here you can see they
are all set to "Non-Raid"
Set Raid Controller to RAID from HBA
Go to Overview à
Storage à Controllers
then click on Setup.
Change the HBA to RAID
Set to At Next Reboot
Click Apply
Click Create Job.
Click Job Queue.
Now reboot the server.
Then double check it
Looks good.
Get the disks Ready
Select Convert to RAID
in the Assign to All section.
Click OK
Click Apply.
Go to the Job Queue.
Watch its status. (click refresh button in upper right)
Once it reaches 100% go
to the next step.
Now they are all set to
Ready.
Create Virtual Drive
Go to Overview à
Storage à Virtual Drives
Click Create
Give it a name OS-RAID-1
set layout to RAID-1 and Media Type to HDD.
Choose the Disks to add
to the Virtual Drive.
Select At Next Reboot
then click Create Virtual Disk.
Click OK
Restart the server to
get this change applied.
After the reboot I can
see those drives are marked as online
And I can see the OS-RAID-1 has been made.
Now to make the raid 6.
Go to Overview à
Storage à Virtual Drives
Click Create
Give it a name
DATA-RAID-6
set layout to RAID-6 and Media Type to HDD.
Choose the Disks to add
to the Virtual Drive.
Select "At Next
Reboot" and click Create Virtual Disk.
Click OK.
And reboot the machine
After a reboot
I can see they are all
online
I can now see that I
have both virtual disks.
Installing from an ISO from the vFlash
I have Ubuntu 26.04
already uploaded to the vFlash (see https://www.whiteboardcoder.com/2026/09/uploading-iso-over-2gb-to-idrac8.html )
Now I want to install
Ubuntu 26.04 from the vFlash onto the Raid 0 I made.
Go to Overview à
Server à vFlash
From the vFlash tool. Select manage then checkbox attached for the ISO you want to install and click Apply.
Now Launch the Virtual
Console
From the Virtual Console
click on Launch Virtual Console
Now power cycle the box.
Watch it reboot in the
virtual console.
Press F10 to set it into
Lifecycle Controller
Click on System Setup
Click on Advanced
Hardware Configuration
Click on System BIOS
Click on Boot Settings.
Click on UEFI Boot
Settings
Click on UEFI Boot
Sequence
Select the vFlash Media
you want in my case UBU26 then click the + button till its at the top.
Click OK
Click Exit
Click Yes
Click OK
Click Finish.
Click Yes.
Now it reboots.
Now install Ubuntu!
Make sure to install on
the correct disk.
Mounting the second drive
After logging into Ubuntu run the following command.
|
> lsblk -o
NAME,SIZE,TYPE,FSTYPE,LABEL,MOUNTPOINT,MODEL,SERIAL |
I can see the new second Raid-6 Drive is at sdb
Let’s confirm it with the perccli tool
First install the tools (if you do not have them)
|
> cd /tmp |
Create a symlink to make your life easier.
|
> sudo ln -fs
/opt/MegaRAID/perccli/perccli64 /usr/local/bin/perccli |
Now run.
|
> sudo
/opt/MegaRAID/perccli/perccli64 /c0/vall show all |
Now let’s partition it and format it
|
> sudo parted /dev/sdb --script mklabel
gpt > sudo pvcreate /dev/sdb1 > sudo mkfs.ext4 -L
Second_raid6 /dev/vg_second/lv_data |
Now let’s see if its there.
|
> df -h
/mnt/second_raid6 |
But this won’t survive a reboot. Let me add it to /etc/fstab
Get the UUID
|
> sudo blkid
/dev/vg_second/lv_data |
In my case UUID="557d406e-d3bf-43c0-bb6c-a66f80365e76"
Now open /etc/fstab
|
> sudo vi /etc/fstab |
Now add this line at the end
|
> sudo vi /etc/fstab |
Add this (adjust for your UUID)
|
UUID=17e43fd1-d3f0-4e86-aa6c-8ea98a8cd880 mnt/second_raid5 ext4 defaults,nofail 0 2 |
Save it
To test it I am going to reboot and make sure it mounts.
|
> sudo reboot now |
Log back in and run
|
> df -h
/mnt/second_raid6 |
Looks good!
