Understanding RAID Concepts and Terminology

The following concepts and terminology is commonly used when describing the
functions of the RocketRAID 2322 Host Adapter.

Initializing a disk writes necessary RAID configuration information to that disk. Disks
must be initialized before configuring them into RAID arrays. The initialization
process will destroy all data on the disk.

Disk Status

New

The disk contains no data and has not been initialized.

Initialized

The disk has been initialized and can be used for array creation.

Configured

The disk has been assigned to one or more arrays, or configured as a
spare disk.
