Notes:

1. A record cannot be created for storage systems other than VSP One B20, VSP E series, VSP 5000 series, VSP G350, G370, G700, G900, VSP F350, F370, F700, F900.
2. If a value cannot be obtained, the field value becomes one of the following:
   • If the micro-version is earlier than 88-03-01, the value is -1.
   • If the calculation is not complete, the value is -2.
   • If the information is invalid, the value is -3.
3. Under certain circumstances, the field value can display as 99999 (for example: before data has been written to newly-created pool or virtual volume).
4. Times are displayed in YYYY-MM-DD hh:mm:ss format. If a value cannot be obtained, an empty character string ("") is displayed.
