- 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.
* Due to a kernel issue, you need to reboot your PowerEdge 1855
system after creating a virtual disk on it, in order to use the
virtual disk that you created. This affects PERC 4/IM controllers.
(116779)
* You can assign a maximum of 10 Global Hotspares using Raidcfg. Use
The Dell(TM) OpenManage(TM) Server Administrator Storage Management
for assigning more then 10 Global hot spares.
SYSCFG Issues:
* Demand based power management (DBPM) option does not work on
PowerEdge 1855 with BIOS firmware versions earlier than A05.
* 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 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.
* 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 baud rate for PowerEdge x8xx systems.
* On PowerEdge 1950, 2950 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
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 Set to "Off" during the next reboot.
