Sun Ultra 27 Workstation Windows Operating System Installation Guide

Removing a Preinstalled Partition Without Deleting the Diagnostic Partition

Diagnostics (system test) software is included on the Tools and Drivers DVD for your workstation. A diagnostic partition is required for the diagnostic test scripts to write their log files. Without a diagnostic partition, the only output is the display on the diagnostic screens. The diagnostic partition is preinstalled on the Sun Ultra 27 Workstation. You do not need to reinstall the diagnostic partition unless you remove it. Instructions for using the diagnostics software are provided in the Sun Ultra 27 Workstation Service Manual

If you remove the diagnostic partition, you can re-create it using the Create Diagnostic Partition option on the Tools and Drivers DVD. See the Sun Ultra 27 Workstation Service Manual for instructions.

To erase all partitions on the boot hard drive except the diagnostic partition, use the Erase Primary Boot Hard Disk option on the Tools and Drivers DVD main menu.
