It should be a known issue:

Add "hdf=scsi" to the kernel command line

dme/readme.txt> 
* 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, you must add "hdf=scsi" on the 
  grub command line in /boot/grub/grub.conf (if "hdf" is your virtual 
  CD drive.)  You can verify that "hdf" is your virtual CD drive by 
  checking /proc/ide/hdf/model.  Other names include "hde".
  The command line should look like this before it is modified:
  
  kernel /vmlinuz-2.6.9-5.Elsmp ro root=/dev/md2 rhgb quiet

  After the modification, it should look like this

  kernel /vmlinuz-2.6.9-5.Elsmp ro root=/dev/md2 rhgb quiet hdf=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 offline.  The " 0 0 0" part should not change, but the 
  "4" may change depending on how many other SCSI hosts are on the 
  system. (141372)
