These issues apply to a Sun Ultra 27 workstation running the minimum supported Solaris OS, or later versions:
Xserver might fail to start on an Ultra 27 workstation running OpenSolaris 2009.06 with dual configuration (two) Nvidia graphics cards (for example, two Nvidia FX3800 graphic cards).
Use OpenSolaris 2008.11.
Use the inbox OpenSolaris Nvidia driver (for example, version 180.29).
This issue will be fixed in Nvidia video driver 185.XX.
This issue is under investigation.
On x64 systems, the Host ID is only created when you configure and use the preinstalled Solaris OS (on the HDD shipped with the system). When you boot the system for the first time, the Solaris OS will randomly generate a unique Host ID. This Host ID is for use with the software license. If you do not use the preinstalled Solaris OS, then there is no need for the Host ID. Because the Host ID is randomly generated during the initial boot, it is not provided on the CIS sheet that is shipped with your system.
Current released versions of the Solaris OS do not have support for RAID through the on-board ICH10R controller. However, RAID is supported through the LSI 3041E HBA controller card.
Open Solaris might fail when VT-d is set to Enabled in the workstation BIOS.
Before installing Open Solaris, access the workstation BIOS and set the VT-d option to Disable.
Open a terminal and type the following command:
# pkg uninstall NVDAgraphics
