Auto LUN with Thin Provisioning virtual volumes

You can perform a manual migration plan on a Thin Provisioning virtual volume or an external
volume. However, you cannot examine the estimated usage rate after the migration because the
usage rate of an external volume cannot be collected.
The following table summarizes the internal volume and Thin Provisioning virtual volume (V-VOL)
combinations under which a volume migration plan can be created.
Table 3 Permissible Internal and V-VOL Combinations
Source Volume
Internal Volume
V-VOL in Normal state
V-VOL in Blocked state due to full
capacity
The migration plan might not be executed if the storage system is experiencing a heavy workload.
Volume Type/Status
A volume with data stored
in cache
Individual LDEV within
expanded LU
All LDEVs in an expanded
LU
A volume undergoing an
Auto LUN operation via
RAID Manager
A volume having the Read

amount of target volumes
are reserved.

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.
