Dynamic Provisioning
You can create a Universal Replicator pair by specifying a DP-VOL (Dynamic
Provisioning virtual volume). DP-VOLs can be assigned to both the TC P-VOL
and S-VOL, or to one of them. However, the following restrictions apply:
• You can use DP-VOLs that are also used in a ShadowImage pair, or in a
Volume Migration migration plan. Before creating the TC pair, delete the
SI pair, or disable the Volume Migration setting. After the pair is created,
re-create the pair or migration plan.
