Release Notes

• 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 12
th
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 <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 Dell’s 12
th
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 12
th
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
SYSCFG Issues
• 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.
• Using the "solcfgparams" option may result in an error message saying "Hardware subsystem error" when
an invalid value is used. It does not indicate a problem with the hardware. Check the option value and try
again.
• The "--solbitrate" option in "solcfgparams" and the "--mgscommbitrate" option in "serialcfgparams" accept
a baud rate of 57600, but tools such as "ipmish" and "solproxy" do not function at that baud rate for
PowerEdge systems.
• On PowerEdge 1950, 2950 and PowerVault NX 1950 systems with internal USB, BIOS setting configuration
for internal USB Port is possible only if User Accessible/external (UA) USB ports are set to "All Ports On." If
UA USB ports are not set to "All Ports On" and if you try to configure the BIOS setting for the internal USB
port using SYSCFG, the configuration will appear to be successful but the changes will not take effect after
the next reboot. If UA USB ports settings are changed from "All Ports On" to "All Ports Off" or "Only Back
Ports On," the USB port will be automatically to "Off" during the next reboot.
