Release Notes

Use both DTK and the Server Administrator from the same release version to get complete supported features of Server
Administrator.
DTK operating system deployment limitation:
DTK does not support operating system deployment, when multiple boot VDs exist on a single controller or when the server has
multiple boot controllers. If multiple boot controllers exist on the server, the boot VD must be created on any one of the controllers,
and the boot VD must be set as first boot device in system BIOS.
DTK does not support Linux operating system deployment in Non RAID (Volume) and SWRAID mode on s100/s300/S110/S130
controllers.
SYSCFG
• Some options may not be present on all systems, which may be due to the BIOS version or hardware feature set. The usage
information generated by running SYSCFG without arguments shows only those options that are valid for your system.
• The --devseq option is present only if you have an available, bootable hard-disk partition. If this option is present in the
configuration file, but not present on your system, you will receive a usage error.
• To enable certain options, to reboot your system. Dell recommends you use the "reboot" command on shell prompt or press the
Ctrl+Alt+Del keys.
• It is required to perform a warm reboot after applying the SYSCFG settings changes on Dell’s 12th generation of PowerEdge
systems.
• If you perform operations that change the --redmem option, reboot your system immediately. It is applicable to both command
line and --infile usage.
NOTE: Additionally, the --redmem option should not be issued with any other command and should be immediately
followed by a system reboot. This is important when you develop scripts that can alter the --redmem setting.
• For options that use text strings such as username, password, hostname, and community string, using characters such as "<,"
">," "|," "=" on the command line can be misinterpreted by the command line parser and may cause errors. To avoid such errors,
use only alphanumeric characters.
• If you set the username using SYSCFG username option, Serial Over Lan (SOL) access for the corresponding user will be
enabled by default. You can disable SOL access for a user using syscfg solaction --userid=--action=disable command.
• The legacy attribute values enable and disable are also supported for Dell’s 12th generation of PowerEdge systems for backward
compatibility. In future releases these arguments might be deprecated. Try to use the values displayed in help message for BIOS
options for Dell’s 12th generation of PowerEdge systems
RAIDCFG
• When creating virtual disks, the chunk (stripe) size is always in KBs. Do not specify any units of measure for the chunk size.
• When providing multiple physical disks for the "create virtual disk" command, do not separate the disks with spaces.
For example, "-ad=1:4, 1:5" causes an error. The correct way to input multiple physical disks is "-ad=1:4,1:5,1:6" or "-
ad=1:4:0,1:5:0,1:6:0".
• If you change the controller mode from SCSI to RAID mode, data loss may occur. Back up any data you require before changing
the modes.
Known Issues
Network limitation:
On spanning tree-enabled network, SUSE Linux Enterprise Server 12 / Red Hat Enterprise Linux 7.x operating system installation on
Dell Power Edge systems might not be successful due to DHCP client time-out.
Workaround: Add netwait=90 in the boot loader option of the suseinst.sh/ lininst7.shscript.
For example, suseinst.sh, kernel/linux/linux autoyast=$DT_SUSE_AUTOINST install=$DT_OS_IMG_PATH
netwait=90
