RHEL8. Install to DELL server with RAID (SAS2008)
In RHEL/CentOS 8 was be removed many drivers for popular enterprise raid-controllers. It brings some troubles when you try to install OS. Without drivers an installation destination section will be empty. No drives will be found. To see your HDD in the server need add drivers back.
With ELRepo it will be easy. ELRepo repository includes a lot of drivers. The full list of supported drives here. I found an ID of raid-controller for my DELL PowerEdge C6320 in the list. Read next, and I show how it is possible install CentOS 8 in the DELL server.
SetupPermalink
First of all we must understand what raid controller is installed into server. Use command lspci -nn
for show all connected devices
Serial Attached SCSI controller [0107]:
LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] [1000:0072] (rev 03)
I get this output in my another similar server with CentOS 7.
Also I check it in the BIOS, and the name is similar - LSI SAS2 MPT Controller SAS2008
.
Main part of this - 1000:0072
- is a device ID.
It helps to us found a right driver from ELRepo.
Next, we need to choose what DUD (driver update disk) we should to use in installation process for our hardware.
Follow to this page and find our ID (1000:0072
).
It point to the mpt3sas.ko
section.
So, we need to use a las mpt3sas
iso images from here.
When I wrote this article it is - dd-mpt3sas-28.100.00.00-2.el8_1.elrepo.iso
.
For using them during installation need to made some required actions. Read the instruction from Red Hat about it.
I just show you the simple method that I used. My server has connected to local network and internet. DHCP-server in the LAN assign an IP-address to the server, and server can download any resources from network. So it is the reason why I prefer to add drivers by http link. What we will need to do?
Run the installation process. When boot menu window has been shown,
press the Tab
key on your keyboard to display the boot command line.
Append the inst.dd=https://elrepo.org/linux/dud/el8/x86_64/dd-mpt3sas-28.100.00.00-2.el8_1.elrepo.iso
boot option to the command line and press Enter
to execute the boot process.
The installer should detect the DUD iso and install the proper drivers. And raid controller with drives will be accessed as installation destination.
So, now you can install the last RHEL/CentOS into DELL Server. After reboot the system the drivers will be included into installed system.
