140 Known Issues and Frequently Asked Questions
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 a 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you could update to a newer version of the kernel.
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.
A: Always use initrd for the Red Hat Enterprise Linux Server installation
from the Dell Systems Build and Update Utility CD
available on the path
server_assistant/drivers .
If the initrd is not available for your operating system, try the latest update of
Red Hat Enterprise Linux Server. Otherwise, you might need to prepare
driver disks for your network or disk controller. Use the drivers from the
Systems Build and Update Utility CD
available on the path
server_assistant/drivers.
