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.
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 unknown.unknown.n-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.
• 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.
• JIT-70261: The syscfg --slot command will not detect the slot in which the server is inserted in the chassis.
