Command Line Interface Reference Guide
Initializes metadata on the specified container. During initialization, a small
amount of disk space is reserved for metadata that the controller uses to keep track
of the array. This metadata is inaccessible to the host. Disks made transportable
(using the TRANSPORTABLE switch of the ADD DISKS command) do not
contain metadata. Units are not initialized; a container is initialized before being
assigned to a unit.
Caution: Observe the following precautions associated with INITIALIZE
command:
■ The INITIALIZE command destroys all metadata on the container
unless you use the NODESTROY switch. The drive does not have the error
detection and data security provided by the metadata that is on
NOTRASPORTABLE disks.
■ The NODESTROY switch is valid only on mirrorsets and striped mirrorsets.
If a partitioned container is initialized, all partitions are eliminated.
■ Issuing an INITIALIZE command on either disks or storagesets
destroys any existing partitions without warning.
Note: Before using or reusing disk devices for storagesets and units that are
configured under ACS V8.7-
x (or an earlier version), initialize disk devices under the
current ACS version before creating and initializing new storage containers and units.
Use the INITIALIZE command:
■ Before creating a unit from a newly installed disk.
■ Before creating a unit from a newly created RAIDset, stripeset, or
mirrorset.
■ To destroy all existing partitions on a container.
