3 Release Notes
This chapter lists the release notes that apply to this release. Each item is presented with an
estimate of its impact, a summary of the note, and a solution.
1. Allow Administrators to Add Options to the Device Section in SVA-generated X Configuration Files
• Impact
Medium.
• Summary
This functionality allows the system administrator to implement device options with
the configuration files generated by SVA.
This can be useful in certain cases, such as, when a device that does not support EDID
is connected to the output port of a graphics card. You can prevent the graphics driver
from using EDID information.
• Solution
As the system administrator, you must set and reconfigure the necessary options in the
/hptc_cluster/sva/etc/X11/templates/Options.device file. Use the
following procedure:
1. Log in as root on the head node of the HP SVA cluster.
2. Use the text editor of your choice to edit the /hptc_cluster/sva/etc/X11/
templates/Options.device file.
A sample configuration file might contain the following lines:
Section "Device"
1
Option "ExactModeTimingsDVI" "True"
2
Option "IgnoreEDID" "True"
Option "UseEDID" "False"
EndSection

that the system administrator sets.
3
The EndSection line is required.
3. Save the file and exit the text editor.
4. Enter the following command from the head node to reconfigure the options in
the file on all the nodes in the cluster:
# pdsh -a sva_install_xconfig

installed on the head node.
• Impact

• Summary

driver rpm installed, the SVA install script fails with the following error message:
upgrade: A newer version 8776-1.0 of nvidia is already installed
• Solution
Uninstall the NVIDIA driver from the head node with the rpm -e command before
running the install script.
