Top Down Creation Capabilities

With the metassist command, you can specify volume characteristics in terms of quality of service. You can specify the following quality of service characteristics:

• size

• redundancy (number of copies of data)

• data paths

• fault recovery (whether the volume should be associated with a hot spare pool)

For cases in which it's important to more specifically define the volume characteristics (or constraints under which the volumes should be created), you can also specify

• volume types (for example, RAID 0 (concatenation) or RAID 0 (stripe))

• components to use in specific volumes

• components that are available or unavailable for use

• number of components to use

• details specific to the type of volume being created (including interlace value for stripes, read policy for mirrors, and similar characteristics)

Additionally, the system administrator can constrain the command to use (or not use) specific disks or paths.
