I have an issue with 2 HP DL60 Gen9 servers. They each contains 2 x 500 G SATA HDDs. I've used Intelligent Provisioning to create a RAID 1 array using the HDDs however, the first issue I noticed is during the OS install process I'm still seeing two HDDs which is weird. Anyway, I tried the following scenarios (using an USB disk):
- installed CentOS 6 and created a RAID 1 array during the OS install
- installed CentOS 6 without any array
- installed CentOS 7 and created a RAID 1 array during the OS install
- installed CentOS 7 without any array
- installed CentOS 7 using RAID + LVM
The problem is that after the install it doesn't boot, saying that no suitable boot device has been found. I did find Install GNU/Linux No System Disk Error -- HP Smart Array
Unfortunately, I am using GRUB but it still doesn't find it. I saw ewwhite's reply asking if a USB stick was used (which is the case for me). Problem is I don't have a DVD writer in the office and it will take 2 days if I get one. Could the fact that I am trying an install from an USB be causing these issues? Thanks in advance.
Talking to HP I actually reset everything to FACTORY settings (previously I only tried default settings) and re-created the logical drive. That seems to have fixed the issue and I am now able to boot into CentOS 7. However, the remaining issue is why am I still seeing 2 drives during the install process even though I have created a RAID 1 array using the HP Smart Storage interface.
