IDE Device Functionality

When a Dell Remote Access Controller (DRAC 4) card is used with any version of Red Hat

Enterprise Linux, the system may lose functionality of IDE devices. To avoid this, pass the

following parameter to the kernel command line at system boot:

linux ide2=0x1f0

Using this kernel command allows the operating system to access the internal CD-ROM drive

as well as the virtual CD-ROM on the DRAC 4.

IDE Tape Drives

To use an IDE tape drive with your system running Red Hat Enterprise Linux 4, add the following

lines to the /etc/rc.local file:

rmmod ide-tape

modprobe ide-scsi

mt -f /dev/st0 stoptions no-blklimits

NOTE:

An issue exists with IDE tape backup units (TBUs) where you will receive

request/invalid command

TBU. Executing the command mt -f /dev/st0 stoptions no-blklimits twice in the rc.local file will resolve this

issue and allow the TBU to work as expected.

System Fans

Disregard all references to the front system fan as documented under "System Fans" in your

Installation and Troubleshooting Guide. A front system fan and a back system fan provide air flow

to cool the system. Because the back system fan provides adequate cooling, the front system fan

has been removed.
