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.

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.

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.

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

following:
