Release Notes

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.

• DTK supports till 144HDD only while performing the RAIDCFG commands, if the HDD count exceeds 144 the command fails.

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section of ks.cfg to update to a newer version of the kernel or use driver disk to install drivers.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

• 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>

</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:

Server having GPU add on card on PCI bus hangs during boot time. As a workaround remove the GPU card and reboot.

RPM installation issue:

During the rpm installation , it displays following error "installing package xxx needs x MB on the / filesystem".

As a workaround , you can use "--ignoresize" option with rpm installation command.
