The partition includes the partition map, which is usually in the first sector of the first cylinder. Refer to your operating system administration guide for steps to determine at what cylinder a partition starts.

In order to do this, make sure that vstart = 2 (one AIX cylinder = 2 Sybase pages on default server) for all user-defined disks.
Refer to your operating system documentation for more information about disk partition administration. The Adaptive Server installation and configuration guide contains additional information about choosing a raw partition for your database device.
