Notes on Preparing Linux OS Installation Media
SBUU performs a media check on the Linux operating system media that is provided during installation.
This is to ensure that you do not copy damaged media that causes the operating system installation to
fail. This is a default action performed by SBUU and you cannot disable it.
It is recommended that you use the optical media obtained from the operating system vendor to install
Red Hat Enterprise Linux or SUSE Linux operating systems using SBUU. If it is necessary to burn the
media using optical drive burning software, make sure that you:
Obtain the ISO image file of the media from known sources.
Burn the media at slower speeds.
Use the "Disk at Once" or a similar option.
Close the session.
Notes for VMware ESX
For details on the hardware support and ESX build number, see www.dell.com/vmware.
Also, see the Dell OpenManage Server Administrator Compatibility Guide and the Dell Systems Software
Support Matrix.
On a system with inbuilt SD card slot, if ESXi Installer and recovery OS is supported, it is shown in the
operating system list for all controllers, independent of whether the SD card is enabled or disabled
in the BIOS.
DVD/CD media used for ESXi HDD (5.0) and ESXi Flash (5.0) are the same.
Notes on Dell Utility Partition installation
Utility Partition is not created if the system on which you are trying to install does not support a Utility
Partition.
Notes on using syscfg and racadm Commands
When a system is booted from SBUU, the /opt filesystem is linked to /tmp filesystem. Some syscfg and
racadm functionality use /opt extensively. If user mounts any other device (like a USB drive) to /tmp and
issues racadm or syscfg commands, the files in /opt will be no longer visible and the commands fails.
User is advised to create a temporary directory under under /mnt and mount the USB devices there
instead of mounting to /tmp.
Limitations
Open Issues and Resolutions for LINUX Operating Systems
Issue 1
Description: When you are using the "Dell Systems Management Tools and Documentation" DVD
through DRAC/iDRAC, SBUU may not eject the DVD before asking you to insert the operating system
media. It displays the error message, "Invalid media inserted."
To fix, unmount the DVD from DRAC/iDRAC; insert the correct operating system media and mount the
drive again.
Issue 2
Description: It has been observed that certain CD burning software fails to prepare the media to pass the
media check.
