When the selected source volume is a primary volume or a secondary volume of a TrueCopy or Universal Replicator pair consisting of external volumes and/or Dynamic Provisioning virtual volumes, there are some target volume candidates that must not be considered.

The following table lists the possible External/DP-VOL - TrueCopy/Universal Replicator pair combinations, and tells which type of volume must not be considered as a target volume based on the TrueCopy/Universal Replicator pair combination and the selected source volume.

CAUTION:
  • If you do the TrueCopy operation so that the TrueCopy pair status becomes other than PSUS/PSUE/PAIR when Volume Migration and TrueCopy share a volume, the Volume Migration process stops.
  • If you do the Universal Replicator operation so that the Universal Replicator pair status becomes other than PSUS when Volume Migration and Universal Replicator share a volume, the Volume Migration process stops.
