• About formatting LDEVs

  The LDEV formatting function, which includes Normal Format and Quick Format, enables you to format volumes (LDEVs). Volumes must be in the blocked status to be formatted.

• Quick Format function

  The Quick Format function allows you to format internal volumes (LDEVs) in the background. While Quick Format operations are in process, you can perform other tasks to configure the storage system. I/O operations from hosts are allowed during Quick Format, but performance might be affected because shared resources such as MP units and cache paths are used during Quick Format operations.

  Use this procedure to perform Normal or Quick formatting on a volume.

• Formatting all LDEVs in a parity group
• Stopping the LDEV formatting process
