##### Virtual Floppy and DVD Drives Not Detected (6570949)

The service processor implements virtual floppy and DVD drives so that they each have their own logical unit number (LUN). This might prevent them from being detected on systems that only configure LUN 0 on each port.

## Workaround

Configure the system to scan all possible LUNs at boot time.

1. Add the following line to `/etc/modules.conf`:

   `options scsi_mod max_scsi_luns=`n

   Where n is the largest number of devices on any port.

2. Go to the `/boot` directory:

   `cd /boot`

3. Run `mkinitrd` to rebuild the boot-time RAM disks.

   On Red Hat systems:

   `mkinitrd -k vmlinuz-`kernel `-i initrd-`kernel

   On SUSE systems:

   `mkinitrd -v initrd-`kernel`.img` kernel

   Where kernel is a kernel-level identifier, such as `2.4.21-292-smp`. You can identify the currently running kernel with this command:

   `uname -r`

   You should also rebuild the RAM disks for any other kernel images in `/boot` that you might use.

4. Reboot.
