Release Notes

• For options that use text strings such as username, password, hostname, and community string, using characters such as "<," ">," "|,"
"=" 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=--action=disable command.
• 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 displayed in help message for BIOS options for 12G server.
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.
• RAIDCFG operations can not be performed on HBA330 and AHCI non-raid mode.
• On Software RAID Controller, NVMe PCIe-SSD add-on card is not supported.
• Lockdown Mode enabled will not impact with Raidcfg functionality.
Known Issues
Network limitation:
On spanning tree-enabled network, SUSE Linux Enterprise Server 12 / Red Hat Enterprise Linux 7.x 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/ lininst7.shscript.
For example, suseinst.sh, kernel/linux/linux autoyast=$DT_SUSE_AUTOINST install=$DT_OS_IMG_PATH
netwait=90
lininst7.sh, kernel /linux/vmlinuz ks=hd:sda$(($GRUB_PART_NO + 1)):/linux/ks.cfg inst.repo=nfs:$
{DT_OS_NFS_LOC} netwait=90
On Debranded/Rebrand servers, Deployment toolkit is not supported.
SYSCFG Issues
• In DRAC , 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 allows to set apc. Though apc is not supported on R815, syscfg does not throw an error
message.
• 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.
• DTK 5.5.0 does not boot on Dell PowerEdge T100. PowerEdge T100 has a BIOS version that is incompatible with the current HAPI
drivers.
• 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 --solbitrateoption in solcfgparams and the --mgscommbitrate option in serialcfgparams accept a baud rate of 57600, but tools
such as ipmishand solproxy do not function at that baud rate for PowerEdge systems.
