Information Update
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
mt -f /dev/st0 stoptions no-blklimits
NOTE:
An issue exists with IDE tape backup units (TBUs) where you will receive illegal
request/invalid command messages on the screen after running an mt command for the
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.
