Chapter 3 Volume Management
3.7 TPV Management
Requirements for a TPP in which the target TPV is registered:
• The "Status" is "
• The free space in the TPP is larger than the capacity of the TPV that is to be balanced
• When the allocation mode for the TPV is "Thick", the free physical capacity for allocating the whole area
exists
• The TPV balancing cannot be performed in the following conditions:
- When the maximum number of volumes is already registered in the ETERNUS DX
- When the total number of TPV balancing, RAID migration, and FTV balancing (*1) processes that are
performed at the same time is 32
- When the total capacity for the TPV balancing, RAID migration, and FTV balancing (*1) processes that
are performed at the same time is 128TB
- When the TPP capacity that can be registered in the ETERNUS DX is insufficient
*1: When the FTRP balancing is performed, the FTV balancing process starts in the FTSP. Refer to
Balancing Flexible Tier Pool" (page 587)
• This function balances the physical allocating area of the TPV among RAID groups of the TPP to which the
TPV belongs. It is not able to balance TPV by RAID migration of the TPV to other TPPs.
• TPV balancing can be performed during the work I/O.
• To check the balancing progress of a TPV, refer to "Balancing Thin Provisioning Volume" in "ETERNUS Web
GUI User's Guide (Operation)".
• The allocation method for the TPV can be checked in the [Volume List] screen. Refer to "Volume (Basic
Information)" in "ETERNUS Web GUI User's Guide (Operation)".
