CMMVC8663E: The command has failed because the specified volume is a target of a FlashCopy mapping with a source volume in an active-active relationship and the storage pool for the new copy is in a different site to the source volume.

Explanation

HyperSwap volumes contain a copy on each site, and copying data from one site to the other introduces significant unnecessary data movement. For a FlashCopy mapping that copies data from a HyperSwap volume, the source volume of the FlashCopy mapping must be entirely on the same site as the target volume. This command would spread the volume across both sites.

User Response

Complete one of the following actions:
  • Delete the FlashCopy mapping and retry the command.
  • Move the FlashCopy target volume to the same site as the source volume:
    1. Use the movevdisk command to change the I/O group for the target volume to one on the same site as the source volume.
    2. Use the migratevdisk command to change the storage pool for the target volume to a storage pool on the same site as the source volume.
    Then retry the command.
