Examples

This example shows how to create a stripeset named STRIPE1 with three disks: DISK10000, DISK20100, and DISK30200:

ADD DISK DISK10000 1 0 0

ADD DISK DISK20100 2 1 0

ADD DISK DISK30200 3 2 0

ADD STRIPESET STRIPE1 DISK10000 DISK20100 DISK30200

This example show how to create a stripeset named STRIPE1 and then create a logical unit from it:

INITIALIZE STRIPE1

ADD UNIT D103 STRIPE1

This example shows how to create a two-member striped mirrorset (a stripeset whose members are mirrorsets), and how to create a logical unit from it. Because you can initialize the stripeset, you do not need to individually initialize the mirrorsets.

ADD DISK DISK10000 1 0 0

ADD MIRRORSET MR1 DISK10000 DISK20100

ADD MIRRORSET MR2 DISK30200 DISK40300

ADD STRIPESET STRIPE1 MR1 MR2
