Set Allocation

This function changes the allocation method for the existing TPVs and FTVs.
There are two allocation modes. The default setting is "Thin".
• Thin
Physical area is allocated to the target area of the volume when a write I/O is received.
This method virtualizes and allocates the storage capacity to reduce the physical capacity of the storage.
• Thick
Physical area is allocated to the whole area of the volume when volumes are created.
This method is used for volumes such as those allocated for the system area to prevent system halts due to
pool exhaustion during operations.
