Requirements for a migration destination TPP:
•
The "Status" is "Available"
•
The capacity of the TPP is more than the capacity of the migration source volume (*1)

*1:
Model
When the migration source is a TPV, the capacity indicates used capacity (the physical capacity
that is allocated from a TPP)
When the migration source is a TPV, the capacity indicates used capacity (the physical capacity
that is allocated from a TPP)
•
Migration cannot be performed under the following conditions:
-
When the maximum number of volumes is already registered in the

-
When a RAID group diagnosis or a disk diagnosis is being performed
in the ETERNUS DX Disk storage system
-
When the RAID group to which the migration source volume belongs
is blocked or failed
-
When Advanced Copy is being performed by specifying the whole
volume in the migration source volume and the settings for the
volume capacity that is to be expanded are performed before and
after migration
-
When the total number of migrations and TPV balancing processes
that are running in the ETERNUS DX Disk storage system exceed

-
When the total capacity of the migration and TPV balancing
processes that are running in the ETERNUS DX Disk storage system
