Release Notes

Known Issues
Network limitation:
On spanning tree-enabled network, SUSE Linux Enterprise Server 12 operating system installation on Dell
Power Edge systems might not be successful due to DHCP client time-out.
Workaround: Add “netwait=90” in the boot loader option of the “suseinst.sh” script.
For example, kernel /linux/linux autoyast=$DT_SUSE_AUTOINST install=$DT_OS_IMG_PATH netwait=90
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.
• 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 shown in help message for BIOS options for
Dell’s 12
th
generation of PowerEdge systems
.
• DTK 5.2 is not supported on Dell PowerEdge T100. PowerEdge T100 has a BIOS version that is
incompatible with the current HAPI drivers.
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 configured RAID or SCSI controller. Configure
the other controllers after you install the Red Hat Enterprise Linux operating system.
