Owner's Manual

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 maximum reliably supported baud rates (--solbitrate) are:
o 57600 for PowerEdge 9G systems without Dell Remote Access Controller 5 (DRAC 5).
o 115200 for PowerEdge 9G systems with DRAC 5.
o If you enter an unsupported baud rate, you may receive an error, "Parameter out of range."
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.
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 into 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.
The option for "powerctl," "softshutdown," causes your system to reboot. If you use a customized kernel
with Advanced Configuration and Power Interface (ACPI) support, this option will work as designed.
