container Commands
container promote
To create a multilevel volume set from a stripe set or volume set,
use the container promote
command. In this case, the
resulting array is an array of single-partition volume sets, each of
which has a single partition from the original array.
Typically, you use the container promote
command as part of
a process to provide fault tolerance for existing volume sets. After
container promote is executed, use container create
mmirror (which provides the fault tolerance) to make this array an
array of mirror sets.
Notes
The container promote command differs from the
container add_level
command as follows:
■ The container create volume command creates a
single-level array.
■ If you use the container add_level command and
specify the ID for a single-level volume set, the result is a
volume set with two partitions.
■ If you use the container promote command and specify
the ID for a single-level volume set, the result is a multilevel
volume set (a volume set with two volumes under it).
Syntax
container promote {container}
Parameters
{container}
Specifies the ID number (0 to 63) of the array to promote to a
multilevel array.
Examples
Before promoting an array to a multilevel array, use the
container list
command to obtain information about any
existing arrays.
