• The total capacity of the selected TPV to be performed Balance Thin Provisioning Volume,
the capacity of the TPVs being performed Balance Thin Provisioning Volume, and the
capacity of volumes being performed RAID Migration, does not exceed 8.0TB (8,388,608MB)
■ Conditions for a TPP where the Target TPV has been Registered
• The [Status] is [Available]
• Free space in the TPP is larger than the capacity of the TPV to be balanced
• In addition to "Conditions for a TPV to be Balanced" (page 284) and
"Conditions for a TPP where the Target TPV has been Registered"
(page 285), the following conditions are also required for balancing a
TPV.
Depending on the status of the ETERNUS DX400/DX8000 series, a
message appears. Click the [OK] button to return to the [Menu] screen.
- The total number of active TPV balancings and RAID Migrations
must be 31 or less
- The maximum number of volumes are not set in the ETERNUS
DX400/DX8000 series
- When Resource Domains are registered in the ETERNUS DX400/
DX8000 series, work volumes can be allocated to the Resource
Domain in which the balancing target TPV belongs (*1)
• This function balances the physical allocating area of the TPV among
RAID Groups of the TPP where the TPV belongs to. It is not able to
balance TPV by migrating the TPV to other TPPs.
• In order to recover normal status (the status before failure), the
configuration information of the ETERNUS DX400/DX8000 series may
be needed. After balancing of all the TPVs have completed, use the
[Export Configuration] function to get the configuration information.
• When Resource Domains are registered in the ETERNUS DX400/
DX8000 series, the TPVs that can be balanced differ depending on the
current user account.
- When logged on using a Total Administrator account, all the TPVs
that are assigned to Resource Domains can be balanced.
- When logged on using a Resource Domain Administrator account,
only the TPVs that are assigned to the relevant Resource Domain
and Shared Resource can be balanced.
• The following operations cannot be performed when balancing a TPV:
- Formatting a TPP where the TPV that is being balanced belongs
(*2)
- Formatting a TPV that is being balanced
(*2)
- Deleting a TPV that is being balanced
- RAID Migration of a TPV that is being balanced
- Balancing of a TPV that is being balanced
- Expanding the capacity of a TPV that is being balanced
- Setting Advanced Copy sessions to a TPV that is being balanced
- Setting Remote Advanced Copy sessions to a TPV that is being
balanced
- Changing the Resource Domain of a TPP where the TPV that is
being balanced belongs
