Q: Using SBUU, can I configure RAID on a system with a SATA 2s controller
connected to a hard drive?
A: SBUU does not support RAID configuration on any system with a SATA 2s
controller connected to a hard drive. To configure RAID on such a system,
use the Ctrl+A option or set the hard drive configuration to Native mode
through BIOS.
Q: I have multiple SCSI and RAID controllers on my system. How can I set
the order in which SBUU looks for controllers?
A: SBUU uses the controller listed first in the BIOS boot order list. If you
want to use another controller for the operating system, go to the BIOS setup
(by pressing F2 as the system starts) and set the controller as the first boot
device.
Q: What should I do if I find that one or more virtual disks are in a failed or
degraded state?
A: If any virtual disk is in a failed or degraded state, do not start the server
setup program. Use the RAID controller's firmware utility (by using Ctrl+A,
Ctrl+M, or Ctrl+C while booting) to reset the RAID controller's state.
Q: How can I configure RAID for disks that appear in Legacy mode?
A: On CERC ATA or CERC SATA RAID controller cards, disks that appear
in Legacy mode will not be available for RAID configuration in SBUU. If you
want to use Legacy mode disks as part of a RAID container, use the RAID
controller firmware utility to initialize the disks. However, if all disks are in
Legacy mode, SBUU may fail to configure RAID on the controller.
Q: Why does SBUU fail during RAID configuration?
A: On systems with less than 256 MB of memory and more than one RAID
controller, SBUU may fail during RAID configuration. Install the operating
system on one adapter and then install additional adapters.
Q: On SAS 5/IR and 6/IR controller cards, disks that appear in Foreign state
are not available for operating system installation in non-RAID mode.
How can I use such disks for operating system installation?
A: On SAS 5/IR and 6/IR controller cards, if you want to use any disk that is in
Foreign state for operating system installation, clear the physical disks by
using the Erase All Physical Disks option in the System Tools section. If all
disks are in Foreign state, SBUU may fail to install the operating system on
the controller in non-RAID mode.
