- If you change the controller mode from SCSI to RAID mode,
expect data loss to occur. Back up any data you want to save
before changing the modes.

KNOWN ISSUES
######################################################################
RAIDCFG Issues:
* You cannot delete a virtual disk on CERC SATA 2S when RAID 1 is
created. The virtual disk can be cleared from the controller BIOS.
* Because of an issue in the kernel, for PowerEdge 1855 systems,
you must reboot your system after you create a virtual disk, to
use the created virtual disk. This only affects PERC 4/IM
controllers.

SYSCFG Issues:
* Demand based power management (DBPM) option does not work on
PowerEdge 1855 with BIOS firmware versions earlier than A05.
* The suboption 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 produce an error message saying
"Hardware subsystem error" when an invalid value is used. This does
not indicate a problem with the hardware. Check the option value
and try again.
* On PowerEdge 700 systems, the console redirection option in the
BIOS has the arguments" off," "serial port 1," and "RAC;"
the equivalent arguments in DTK are "off," "serial port 1,"
and "serial port 2."
When the argument is set to "serial port 2" in DTK, the option
corresponds to "RAC" in the BIOS setup.
* The "--solbitrate" option in "solcfgparams" and the
"--msgcommbitrate" option in "serialcfgparams" accept a baud
rate of 57600, but tools such as "ipmish" and "solproxy" do not
function at this baudrate for PowerEdge x8xx 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 you try to configure the BIOS setting for the internal USB port
