An error message is displayed beside the copy set

Edit online

This condition occurs when you create a copy set.

Problem

This error message might indicate that it was not possible to create a valid copy set for the volume. A valid copy set might not be created for the following reasons:
  • The volume type and capacity of all the volumes in the copy set did not match.
  • One or more of the volumes are protected.
  • One or more of the volumes are Space Efficient volumes. A Space Efficient volume is allowed as the target volume role (T1) in a FlashCopy® session.
  • When using the auto-generated volume pairing option to create DS8000 LSS-wide or storage system-wide copy sets, the volume IDs did not match.

To display detailed information about the error, click the Show copy set link.

Action

Verify the following items:
  • The selected volumes are of the same type and size.
  • The volumes are not protected.
  • The volumes are not Space Efficient volumes for a FlashCopy session.
  • The volumes match when using the auto-matching function.
