User's Manual

96 Known Issues and Frequently Asked Questions
Q: Can I use this NULL username to remotely log in to a system’s BMC?
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, --solcharsendthreshold are from 1 to 220.
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: Recreate 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 CD 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: What is the version of the Linux kernel used?
A: The Linux kernel is derived from 2.6.9-42 The source RPM (SRPM) for the Linux kernel is available
on /mnt/cdrom/srpms
.
Q: Can I use a 2.4 Linux kernel?
A: Yes. You could integrate the DTK tools into your own embedded Linux. See "Deployment Using
Customized Embedded Linux."
Q: Can we use the same sample scripts that we have from earlier versions of DTK?
A: The scripts written for the previous versions (1.x) of DTK will not work in DTK 2.x versions for
embedded Linux. See the directory /opt/dell/toolkit/template/scripts for the sample scripts.
Q: After I install legacy operating system on a newer Dell system, the Linux kernel does not boot and
panics.
A: After installing the initial ramdisk image, you could install the driver or you could update to a newer
version of the kernel.
