Users Guide

A: Ensure that the RAID controllers can be seen in the BIOS during POST. If the BIOS does not detect the controller, then
RAIDCFG does 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 enables you to select the number of array disks in a span for the nested RAID levels (RAID-10, RAID-50, and
RAID-60). The default (minimum permissible) span length value is 2 for RAID-10, 3 for RAID-50, and 4 for RAID-60.
Q: PARTCFG cannot enumerate the virtual disks created by RAIDCFG. What must be done?
A: A reboot is required for PARTCFG to enumerate virtual disks after creating a virtual disk using the RAIDCFG command.
SYSCFG questions
Q: Can I use the SYSCFG utility to configure Point-to-Point Protocol (PPP) over the serial port to access my RAC?
A: No. The Baseboard Management Controller (BMC) firmware does not support PPP configurations for the serial port.
Q: The SYSCFG utility --lancfgparams option has suboptions that configure the IP address, Gateway, and Subnet
Mask for the system BMC. There is also a MAC address. Are these the same as the operating system network
parameter of the managed system?
A: No. The Baseboard Management Controller (BMC) has its own IP address, Gateway, Subnet Mask, and MAC address values.
Q: What is the minimum configuration needed to support BMC Platform Event Filtering?
A: You must enable LAN-channel access pefalerting and ensure that you set the BMC IP address and Gateway values for
alerting.
Q: I installed the factory defaults for the BMC of my system. Then, I enabled BMC user ID 3. What is the username
for this user ID?
A: The default username for user IDs 3 to 10 is NULL.
Q: Can I use this NULL username to remotely log in to a BMC of a system?
A: No. Remote login using a NULL username is not allowed. It is recommended that you always provide a non-null, valid
username for the user ID when you enable a BMC user ID.
Q: Are duplicate usernames allowed in the BMC?
A: No. If you enter a username value that already exists, the SYSCFG utility returns an error code of 89, which means This
username is already in use. Enter a unique username.
Q: In --solcfgparams, when I set the Serial Over LAN (SOL) character send threshold using solcharsendthreshold to
be 225, I get a Hardware subsystem error. Invalid data field in request. What are the valid values?
A: The range of valid values for --solcfgparams and --solcharsendthreshold are from 1 to 220.
Q: How do I enable console redirection on a modular system?
A: Set the --serialcomm option value to enableconred. For example, syscfg -serialcomm=enableconred.
Embedded Linux questions
Q: After installing Linux, I am not able to boot to the utility partition by pressing the <F10> key during reboot.
A: Re-create the utility partition using the upinit.sh script and install grub in the boot partition.
Q: When booting DTK through PXE, my system displays error messages, unknown behavior, and also leads to a
kernel panic sometimes. However, booting from the media causes no problems.
A: Ensure that you specify the correct RAMDISK size in the pxe config file before booting through PXE. A sample pxe config
file is provided in /mnt/cdrom/isolinux/isolinux.cfg.
Q: Can we use the same sample scripts that we have from earlier versions of DTK?
A: The scripts written for the previous versions of DTK do not work in the later versions for embedded Linux. For the sample
scripts, see the directory /opt/dell/toolkit/template/scripts .
Q: After the DTK deployment is complete, the Red Hat Enterprise Linux Server installation keeps going into
attended mode or halts with the message ks.cfg not found.
