Release Notes

• 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:
Pre-Boot Environment is not supported while booting DTK on TFTP boot method as this protocol is not supported for stage-2 booting
process. Supported Methods of Installation:
Table 2. Methods for protocol
Boot Method Direct ISO Boot Method Initrd Method
NFS Yes Yes
HTTP Yes Yes
On some 12th and 13th generation system servers, booting DTK using internal DVD drive in the UEFI mode may not boot as the drivers are
not carried.
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.
On PowerEdge servers MX840C and MX740C shared Ethernet port is used in iDRAC management, installing Red Hat Enterprise 7.5
operating system using primary Ethernet port will fail to mount the NFS server, due to limitation in rh_installer.
