Owner's Manual

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 "--solbitrate" option in "solcfgparams" and the "--mgscommbitrate" option in "serialcfgparams"

accept a baud rate of 57600, but tools such as "ipmish" and "solproxy" do not function at that baud rate

for PowerEdge systems.

On PowerEdge 1950, 2950 and PowerVault NX 1950 systems with internal USB, BIOS setting

configuration for internal USB Port is possible only if User Accessible/external (UA) USB ports are set to

"All Ports On." If UA USB ports are not set to "All Ports On" and if you try to configure the BIOS setting for

the internal USB port using SYSCFG, the configuration will appear to be successful but the changes will

not take effect after the next reboot. If UA USB ports settings are changed from "All Ports On" to "All Ports

Off" or "Only Back Ports On," the USB port will be automatically to "Off" during the next reboot.

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.

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 Modify the '%post' section of "ks.cfg" to update to a newer version of the kernel or use driver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.

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.
