*1: When Resource Domains are registered in the ETERNUS DX400/DX8000
series, and if the sufficient number of Assignable Resources for Logical
Volumes does not exist in the Resource Domain in which the balancing target
TPV belongs, balancing of a TPV cannot be performed. The number of
Logical Volumes that have been assigned to the relevant Resource Domain
and the number of Assignable Resources can be checked using the
[Resource Domain List] function.
*2: If any of the operations described above are executed, an error occurs and
the balancing of a TPV is stopped.
The progress of a balancing TPV can be checked with the [Progress of
Balance Thin Provisioning Volume] function.
When the balancing of a TPV cannot be executed, a message to that
effect is displayed. Click the [OK] button to return to the [Menu]
screen.
