How to get Centos 8.1 installer to see Perc 6/i attached SAS disks?
The Dell t7400 hardware boots MS-Windows properly from Perc 6/i attached SAS disks. Dell Bios A11 shows 3 virtual drives at initialization.
There are four 285gb disks attached to the Perc 6/1 of which disks 0+1 are Raid-1 and are bootable and boot MS-Windows (i.e. 3 VDs).
The other 2 disks are raid0 and I want to install linux on the 3rd / 4th disks and use grub to dual boot.
Centos 8.1 is on usb-pen-drive from which I boot, but it cannot see any of the 4 SAS drives for the "installation destination".
Perc 6/i has bios 6.2.0-0013 and firmware 1.22.02-0612, bios controller is enabled and vd 0 is bootable.
While Centos 8.1 cannot see these Perc 6/i attached disks, if I boot the Ubuntu 20.04 installer it sees all of the SAS disks attached to the Perc 6/i controller.
