Release Notes

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.
RAIDCFG Issues
• If both the software and hardware RAID is enabled, raidcfg will show the same controller ID for both the controllers. Disable either
software raid or insert the hardware raid other than PCIe slot 0 in the server.
• 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 H740 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.
• The virtual media should be disabled for SLES 12 OS installation on Dell’s 11th generation of PowerEdge servers.
