Owner's Manual

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.
• 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.
• 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
shown in help message for BIOS options for 12G server.
RAIDCFG Issues
• You can assign up to 10 Global hot spares using Raidcfg. Use the Dell OpenManage Server
Administrator Storage Management for assigning more than 10 Global hot spares.
• USB keys should not be mounted to the /tmp directory. Inside the /tmp directory, create a new
directory and mount the USB to this.
• On Dell PERC H310 controllers, conversion of a RAID Capable Disk to Non-RAID disk and vice
versa is not supported using raidcfg.
Operating System Installation Issues
• Installation of legacy Red Hat Enterprise Linux operating systems may fail due to lack of support
for new hardware. Modify the '%post' section of "ks.cfg" to update to a newer version of the
kernel or use driver disk to install drivers.
• The Red Hat Enterprise Linux operating system installation may fail on systems equipped with
multiple RAID and/or SCSI controllers, whether installed on the system board or in PCI slots. This
failure may occur when using "Server Setup" or performing a manual installation. When two or
more RAID or SCSI controllers are present, install Red Hat Enterprise Linux with only one
