- Attention threshold: "5" - "80"
→ A confirmation screen appears.
• An error screen appears in the following conditions:
- When the "Name" field is not input
- When the "Name" does not satisfy the input conditions
- When the "Name" already exists
- When the "Thin Provisioning Pool Total Capacity" field is not input
- When the total value of TPP capacity to be created and existing TPP capacity exceeds the
maximum TPP capacity for each model
- When a TPP that meets the specified conditions (disk type, RAID type, and capacity that is
equal to or larger than the specified value) cannot be created with the installed drives in the
