Release Notes

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.
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the %post section of ks.cfg to update to a newer version of the kernel or use driver disk to install drivers.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 Dells 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:
1. In device map section,
<device_map_entry>
<firmware>hd0</firmware>
<linux>/dev/sdc</linux>
</device_map_entry>
Change hd0 to /dev/sdc
2. In grub config section, change /dev/sda5 to /dev/sda6
3. 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 7.2 core operating system limitation.
Instrumentation Issues
The "/opt/dell/srvadmin" directory in the DTK ISO image should be writable. It enables the instrumentation services to work
properly.
DTK tools installation limitation:
DTK tools installation is not supported on CentOS operating system.
Unsupported configuration:
