■Array Drive Module Status Descriptions

The Disk Drive / Array Status screen displays the status of each VTSS array drive as a two-character code. The first character defines the partition a specific drive is associated with; the second characther defines the current state of the drive. For example, a status of ‘P.A’ indicates that a drive is in production partition (‘P’) and active (‘A’). The four types of drive partitions are:

•Production Partition (P) – contains drives that are usable for storing and retrieving pro- duction data

•Media Acceptance Test Partition (M) – a holding partition; contains drives that can be as- signed to the spares partition

•Spares Partition (S) – a holding partition; contains drives that can be used primarily for three functions: array formation; drive reconstruction; and draining an array, an entire ar- ray unit, an entire drive tray, or a single drive.

•Unavailable Partition (U) – any slot or drive not under control of the user, including slots that do not have an array drive installed, slots that contain array drives but are not active, and slots that contain broken array drives.
