FlashCopy

FlashCopy® provides an instant, point-in-time copy on a storage unit. The process of creating a FlashCopy relationship consists of selecting source and target volumes. You can manage your FlashCopy relationships by viewing their properties and setting options for a volume pair.

FlashCopy — Main page
Use this page to create new FlashCopy relationships between volume pairs or to modify, delete, or view information about existing FlashCopy relationships between volume pairs. After you create a FlashCopy relationship, you can read and write to both the source and the target volumes.
Create FlashCopy
Use this page to select source and target volumes for a single FlashCopy relationship (a single target volume for each source volume) or for a multiple relationship FlashCopy (a single source volume and multiple target volumes). You can select one or more source volumes.
Create FlashCopy — Advanced options
Use this page to select advanced copy options to use when you want to allow a target volume to be restored in an existing, persistent FlashCopy relationship that was created without the revertible feature enabled.
Delete FlashCopy
Use this page to select and confirm which FlashCopy relationships to delete.
Initiate background copy
Use this page to confirm the volume pairs on which to initiate a FlashCopy background copy.
Resynchronize FlashCopy target
Use this page to resynchronize the target volumes of selected FlashCopy volume pairs. Only changed data is copied from the source to target volume when subsequent FlashCopy operations are run.
Resynchronize FlashCopy target — Options
Use this page to select which options are used to resynchronize the target volumes of selected FlashCopy volume pairs. Only changed data is copied from the source to target volume when subsequent FlashCopy operations are run.
Reverse FlashCopy
Use this page to reverse the FlashCopy relationship. When you reverse the FlashCopy relationship, the original source volume becomes the target volume and the original target volume becomes the source volume.
Reverse FlashCopy — Advanced options
Use this page to select one or more copy options to reverse the FlashCopy relationship. When you reverse the FlashCopy relationship, the original source volume becomes the target volume and the original target volume becomes the source volume.

Use this page to verify the characteristics of the volume pair and the options that you want to use when restarting an existing, persistent FlashCopy relationship.
Reset target write inhibit
Use this page to confirm the FlashCopy relationships for which the write inhibit will be reset and then to complete the reset.
View relationships — Commit FlashCopy changes
Use this page to confirm which FlashCopy target volume will be updated with data from its source volume when data is not consistent between the volume pair.
View relationships — Discard FlashCopy changes
Use this page to confirm the FlashCopy volume pair on which updates to the target volume of the volume pair will be discarded and restored to a previous FlashCopy relationship. The FlashCopy relationship is not deleted until changes are discarded.
