Using Raw Data Slices

The SunOS operating system stores the disk label in block 0, cylinder 0 of each disk. This means that using third-party database applications that create raw data slices must not start at block 0, cylinder 0, or the disk label will be overwritten and the data on the disk will be inaccessible.

Do not use the following areas of the disk for raw data slices, which are sometimes created by third-party database applications:

1. Block 0, cylinder 0, where the disk label is stored.

2. Avoid cylinder 0 entirely for improved performance.

3. Slice 2, which represents the entire disk.
