Dec 1 10:16:28 r2p2 kernel: Device not ready. Make sure there
is a disc in the drive
* Servers running Red Hat Enterprise Linux version 4 should use the
SCSI-IDE driver rather the native IDE driver to avoid system errors
when the DRAC 4 is reset. To do this, add "hdf=ide-scsi" on the grub
command line in /boot/grub/grub.conf (if "hdf" is your virtual
CD drive.) Verify that "hdf" is your virtual CD drive by checking
/proc/ide/hdf/model. Other virtual CD drive names include "hde".
The command line may look like this before it is modified:
kernel /vmlinuz-2.6.9-5.Elsmp ro root=/dev/md2 rhgb quiet
After modification, it should look like this:
kernel /vmlinuz-2.6.9-5.Elsmp ro root=/dev/md2 rhgb quiet hdf=ide-scsi
The SCSI layer will take the virtual CD-ROM device off-line when
the RAC card is reset. To bring it back online, issue the following
two commands:
echo "scsi remove-single-device 4 0 0 0" >/proc/scsi/scsi
echo "scsi add-single-device 4 0 0 0" >/proc/scsi/scsi
"4 0 0 0" represents the host, channel, ID, and lun of the virtual
CD drive. This is available in /proc/scsi/scsi, even after the
device is off-line. The "0 0 0" should not change, but the
"4" may change depending on how many other SCSI hosts are present in
the system. (141372)
* In modular Red Hat Enterprise Linux kernels, USB flash drives
require the sd_mod (scsi disk module) to be loaded. If a
Red Hat Enterprise Linux-based Virtual Media client system has no
SCSI disks, the sd_mod may not load during the startup and will
require manual loading. To load sd_mod manually, type this command
as the root user:
modprobe sd_mod

* When the DRAC 4 resets, the virtual drives disappear. On Red Hat
Enterprise Linux version 4, hotplug IDE is not supported -
the system may hang when a remount of the virtual drives is
attempted. Do not attempt to remount virtual drives after a
firmware update; you must restart the server to regain access
to the drives.
* When using Console Redirection on a managed system running Red Hat
Enterprise Linux, the focus (cursor moved back over an object)
follows the cursor. Occasionally, the text windows in Console
Redirection lose focus. Before attempting to type in a text window
in a Console Redirection window, click the mouse in the text
window's space bar or top menu bar to ensure that your target text
window has the focus on the correct window or application that you
