If you are working in

aV-Switch cluster, this volume must be configured on both V-Switches.

The system default for the number of children data is being striped across is two. Therefore, you only need to specify the number of children for numbers greater than two.

Example:

In Figure 46, page 99, a striped volume, Stripe 1, is created across four children: Simple 2, Simple 4, Simple 8 and Simple 10. The striped unit size is 100 blocks, meaning that in each read/write function, 100 blocks of data are read/written into Simple 2; then 100 blocks into Simple 4;. then 100 blocks into Simple 8; then 100 blocks into Simple 10 and then back again to 100 blocks in Simple 2 until the end of the data chunk.
