Many thanks for the reply and link!

When you boot up and go into the install, press tab key to get to your install options.
From here append cciss.cciss_allow_hpsa=1 hpsa.hpsa_simple_mode=1 hpsa.hpsa_allow_any=1 to your boot options.

When the installer boots up, you should see your logical volume and use it as an install destination. Select it and install your system

If it helps, I have a copy of the kmod-cciss driver compiled for ClearOS 7.x here.

UPDATE - After install ClearOS 7 you will have to boot into rescue mode and change grub2 configuration add "hpsa.hpsa_simple_mode=1 hpsa.hpsa_allow_any=1" to the /etc/default/grub file


Boot up to rescue mode.

After install the ClearOS 7 reboot it, at the boot manual press e to edit boot option and add "rescue hpsa.hpsa_simple_mode=1 hpsa.hpsa_allow_any=1" at the end, then Ctrl - X to boot the system.

Add hpsa to grub.

edit /etc/default/grub.cfg and add this to GRUB_CMDLINE_LINUX hpsa.hpsa_simple_mode=1 hpsa.hpsa_allow_any=1

vi /etc/default/grub.cfg

#/etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="ClearOS"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=clearos/root rd.lvm.lv=clearos/swap rhgb quiet hpsa.hpsa_simple_mode=1 hpsa.hpsa_allow_any=1"
GRUB_DISABLE_RECOVERY="true"

save and exit
:wq

Reconfigure grub.
After that run grub2-mkconfig -o /boot/grub2/grub.cfg to reconfigure grub

Reboot your system.

Eric,

I tried your solution on both ClearOS and CentOS and could not get it to work on either with a DL160 with a H240 controller. Any thoughts?

After you have added hpsa_simple_mode and hpsa_allow_any to grub you need to update both legacy boot and EFI boot;

#Legacy boot
grub2-mkconfig -o /boot/grub2/grub.cfg

#EFI boot - do both to be sure.
grub2-mkconfig -o /boot/efi/EFI/clearos/grub.cfg

Otherwise if you tinker about in the BIOS one day and switch it to EFI boot it won't find your P400 RAID card.
