142 Known Issues and Frequently Asked Questions
Q: Why can’t I see any controllers using RAIDCFG?
A: Ensure that the RAID controller(s) can be seen in the BIOS during POST.
If the BIOS does not detect the controller, then RAIDCFG will also not
detect it. Also ensure that the controller is set to RAID mode and not any
other mode in the controller BIOS.
Q: What is span length?
A: Span length is the field needed when you try to create a RAID 50. The
number represents the span size of the RAID 5.
Q: What pre-operating system environments are PERC 3/Di, CERC SATA
1.5/6ch, and CERC SATA 1.5/2s controllers supported on?
A: They are supported only on embedded Linux.
Q: PARTCFG cannot enumerate the virtual disk(s) created by RAIDCFG.
What should be done?
A: A reboot is required for PARTCFG to enumerate virtual disks after
creating a virtual disk using the RAIDCFG command.
SYSCFG Questions
NOTE: In a Linux environment, the DTK utilities do not have a .exe extension.
Q: On x7xx systems, when I set arguments for --sata0 and --sata1 using DTK
CLI and reboot the system, the BIOS setup shows the earlier settings for --
sata0 and --sata1.
A: You need to set the --idectrl to auto before you can change the settings for
--sata0 and --sata1.
Q: On x7xx systems, the BIOS setup shows --conred arguments of --serial1
and --rac, whereas the DTK CLI shows them of --serial1 and --serial2.
A: The --serial2 argument in the DTK CLI corresponds to the --rac argument
in BIOS setup.
Q: Can I use the SYSCFG utility to configure Point-to-Point Protocol (PPP)
over the serial port to my access my RAC?
A: No. The baseboard management controller (BMC) firmware does not
support PPP configurations for the serial port.
