SYSCFG Issues

• In DRAC 5, 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 sets apc. Though apc is not supported on R815, SYSCFG does not throw an error

message.

• 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.

• The legacy attribute values enable and disable are also supported for Dell’s 12th generation of PowerEdge 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 Dell’s 12th generation of PowerEdge systems.

• DTK 5.3 is not supported on Dell PowerEdge T100. PowerEdge T100 has a BIOS version that is incompatible with the current

HAPI drivers.

RAIDCFG Issues

• 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 H310 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%post section of ks.cfg to update to a newer version of the kernel or use driver disk to install drivers.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.

• When deploying SUSE Linux Enterprise Server version 11 on PowerEdge M915 using DTK automated script (autoinst.xml), do

the following:

a. In device map section,

<device_map_entry>

</device_map_entry>

Change hd0 to /dev/sdc

b. In grub config section, change /dev/sda5 to /dev/sda6

c. If installer reports any missing packages, delete the packages from autoinst.xml.

Secure Boot limitation on UEFI mode:

On installation of the operating system in UEFI mode when secure boot BIOS option is enabled, DTK ELI is not supported. This is

due to the CentOS 6.5 core operating system limitation.
