HP XP24000/XP20000 for FlashCopy Mirroring Software User Guide (T5240-96012, November 2011)

1. Establish a Version 1 relationship by using simplex volumes. When the relationship is
established, the volume status changes to F-Copy.
2. After the relationship is established, the on-demand copy operation starts when the S-VOL is
updated.
The background copy operation will not be performed when the NOCOPY option is specified.
For details on the NOCOPY option, see (page 24).
3. The relationship will be automatically withdrawn when the background copy operation is
completed. However, if the relationship is established with the NOCOPY option, the relationship
is not automatically withdrawn when the on-demand copy operation is completed.
When the background or on-demand copying of extent data fails, the Version 1 relationship will
be released automatically, the T-VOL will become blocked, and the status of the relationship will
become simplex.
