Centos8 Installer can't detect disk

santhosh94 · 11-12-2019, 01:32 PM

I'm trying to install Centos8 using Gui on a Dell R710. The installer cannot detect the virtual disk while the Centos7 installer can detect. On other note - The same Centos8 installer detected the virtual disk on a Dell R620 machine. I couldn't figure out why the Centos8 installer fails to do that specifically on R710 machine.

Your duplicate was reported; this is the second time you've intentionally opened a duplicate thread, read the LQ Rules.

That said, have you looked at the manual for the 710, and performed the steps indicated? Contacted Dell support?

His duplicate was also mentioned at dupe.

I'll have to assume you have some host running some OS. Then you have some Virtual Machine program running. I guess the weak link here is how you created this virtual machine. The way it attaches a disk to the virtual machine may be in ide scsi or sata and the chipset may need to be know.

Can we get more information on this?

The documentation that I linked to has information on that, including instructions on setup. The machine apparently has VMware ESXi by default.

Code:

1.3. Storage Location
For installing the operating system on a virtual disk, ensure that a Software RAID or PowerEdge RAID controller is installed and at least two 
(or more, depending on the desired RAID level) hard-disk drives are available. In specific scenarios, OS can be installed on SD cards.

My understanding was that the OP is using a virtual machine. Little of the real hardware would be involved in that case. However I may misunderstand the question.

Correct; as said, the link specified installing either through iDRAC or through the Lifecycle controller that's built-in to the 710. Unless the OP actually defines a disk (either 'real' or virtual), there won't be anything to install TO. And a virtual disk does point to some 'real hardware' at some point.
