Release Notes

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.
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.
 It is required to perform a warm reboot after applying the syscfg settings changes on Dell
PowerEdge 12G 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 <space>, "<," ">," "|," "=" 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=<userid> --action=disable" command.
 The legacy attribute values enable and disable are also supported for 12G 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 12G server.
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.
 Use the slots 0-3 of the system to create a boot VD or assigning hot spare (dedicated or global) on Dell
PERC S130 controller. If you use any other slots, the system encounters issues during wake up from
hibernation.
Known Issues
SYSCFG Issues
 In DRAC 5, the --virtualmedia and --vflash options do not work if there is an active virtual media session.
Disconnect the virtual media using the DRAC GUI. Log in to DRAC. Click Media > Virtual Media >
Disconnect.
 The syscfg --bootseq command detects CD-ROM with SAS/SATA controllers as unk.emb.1.
 On R815, syscfg power --profile option sets apc. Though apc is not supported on R815, syscfg does not
throw an error message.
