Starting with RHEL/EL7 the drivers for the raid controller card, the P400i, are no longer loaded in by default. When you go to install Centos 7 on one of these you will likely see that it doesn’t detect your LD.
When you boot up and go into the install, press
tab to get to your install options. From here append
hpsa.hpsa_simple_mode=1 hpsa.hpsa_allow_any=1 to your boot options.
The install should now pick up on your LD and you should be able to install as normal. After you reboot however you’ll have to make this more permanent. At the grub screen press
e to get back to your boot options. From here append
hpsa.hpsa_simple_mode=1 hpsa.hpsa_allow_any=1 again so that you can get into the machine.
Once you’re logged in open up
/etc/default/grub and add these options to the file. The file should now look something like:
GRUB_TIMEOUT=5 GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap crashkernel=auto rhgb quiet hpsa.hpsa_simple_mode=1 hpsa.hpsa_allow_any=1" GRUB_DISABLE_RECOVERY="true"
grub2-mkconfig -o /boot/grub2/grub.cfg and reboot the machine. It should be detected from now on each time you boot.
