The migration plan might not be executed if the storage system is experiencing a heavy workload.
When you specify a Thin Provisioning virtual volume or an internal volume which is used for the
Continuous Access Synchronous pair as a source volume, see the
specifying a target volume. The Continuous Access Synchronous pair combination of an internal
volume as a P-VOL and a Thin Provisioning virtual volume as an S-VOL is not recommended.
If the capacity of a Thin Provisioning virtual volume is increasing, this volume cannot be specified
as the source or target volume in an Auto LUN plan. It will also be impossible to reserve or remove
the reserve attribute for a virtual volume whose capacity is increasing. You must ensure that the
capacity of a Thin Provisioning virtual volume is not increasing if you plan on using that virtual
volume in an Auto LUN plan.

Journal V-VOLs
When the selected source volume is a P-VOL or an S-VOL of a Continuous Access Synchronous or
Continuous Access Journal pair consisting of internal volumes and/or Thin Provisioning virtual
volumes, there are some target volume candidates that should not be considered. The following
table lists the possible Internal/V-VOL - Continuous Access Synchronous/Continuous Access Journal
pair combinations, and tells which type of volume should not be considered as a target volume
based on the Continuous Access Synchronous/Continuous Access Journal pair combination and
the selected source volume.

A migration plan can be created.
If operations change the configuration
of the storage system after the initial
volume migration, any subsequent
volume migration must be executed at
an interval which is calculated by the
following formula:
(Pool_Capacity x 3 (seconds)) + 40
(minutes)
A migration plan can be created. A
warning message appears if there is a
possibility that the data size may
exceed the pool threshold after
migration.
