Default Boot-Disk Partition Layout Preserves the Service Partition

The Solaris installation program uses a default boot-disk partition layout to accommodate the diagnostic or Service partition. If your system currently includes a diagnostic or Service partition, the default boot-disk partition layout enables you to preserve this partition.

If you install the Solaris OS on an x86 based system that does not currently include a diagnostic or Service partition, the installation program does not create a new diagnostic or Service partition by default. If you want to create a diagnostic or Service partition on your system, see your hardware documentation.
