Messages looking like this are displayed by RAID controller BIOS extensions when no RAID arrays are found. This is normal if the server has not been configured yet (but seeing this on a previously working server would be bad news).
When using IBM servers, a convenient way to perform initial server configuration and installation of a supported operating system is by booting from the IBM ServerGuide Setup and Installation CD/DVD (image downloadable from the IBM support site). The GUI offered by this disk includes RAID setup options for typical configurations.
If you cannot use ServerGuide (e.g., the OS you want to install is not supported by ServerGuide, or you need some nonstandard configuration which cannot be performed in the ServerGuide interface), you can configure RAID manually. There are several options to do this on IBM servers:
When prompted during server startup, enter UEFI setup, then enter the RAID controller UEFI setup interface (don't remember the exact path in UEFI setup menus now).
If you are using legacy boot instead of UEFI, wait until the legacy BIOS extension for the RAID controller starts initializing, then press the key combination indicated on the screen to enter the controller configuration utility (this combination can differ depending on the controller model).
Boot from a CD or USB media which contains a bootable OS and a configuration utility compatible with the RAID controller (e.g., SystemRescueCd). This is the most flexible way (often the BIOS/UEFI configuration utilities do not support the whole range of RAID controller capabilities), but also the most complex one.
