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:
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.
Workaround: User has to modify the installer script (lininst7.sh) to add correct interface name displayed (i.e. "ip=pXpY:dhcp" where X,Y =
port number) or modify the grub boot parameter option.
For example:
lininst7.sh script, linux /linux/vmlinuz ks=hd:UUID=${DEV_UUID}:/linux/ks.cfg inst.repo=nfs:$
{DT_OS_NFS_LOC} ip=<interface name>:dhcp
On PowerEdge servers MX840C and MX740C shared Ethernet port is used in iDRAC management, installing Red Hat Enterprise 6.9
operating system using primary Ethernet port will fail to mount the NFS server, due to limitation in rh_installer.The Red Hat Enterprise 6.9
does not carry inbox driver on MX840C and MX740C PCI Network adopter cards.
Workaround: User has to modify the installer script (lininst.sh) to add correct interface name displayed (i.e. "ip=pXpY:dhcp" where X,Y =
port number) or modify the grub boot parameter option.
Also user should use driver disk option and pass kernel boot parameter “linux dd” on MX840C and MX740C to get the IP for PCI Network
adopter.
For example:
lininst.sh script, linux /linux/vmlinuz linux dd ks=hd:UUID=${DEV_UUID}:/linux/ks.cfg
ksdevice=<interface name>:dhcp
On Debranded/Rebrand servers, Deployment toolkit is not supported.
JIT-103685: If Server Administrator is installed on the web server and you install DTK services, the Data Manager services stops.
Workaround: Restart the Data Manager services.
