NOTE:
• Round up the value enclosed by two up arrows (↑) to the nearest whole number.
• The user-specified CV capacity is expressed in blocks.
• The boundary value is expressed in kilobytes. The boundary value depends on volume emulation
types and RAID levels (see Table 28 ).
If the emulation type is other than OPEN-V
• If the CV capacity unit is MB (megabytes):
To calculate the CV's user area capacity, use the following formula. The resulting user area capacity
is expressed in kilobytes.

NOTE:
• Round up the value enclosed by two up arrows (↑) to the nearest whole number.
• The user-specified CV capacity is expressed in megabytes.
• The slot capacity is expressed in kilobytes. The slot capacity depends on volume emulation
types (see Table 29 ).
To calculate the CV's entire capacity, use the following formula. The resulting entire capacity is
expressed in megabytes.

NOTE:
• Round up the value enclosed by two up arrows (↑) to the nearest whole number.
• The user area capacity is expressed in kilobytes.
• The management area capacity is expressed in kilobytes. The management area capacity
depends on volume emulation types (see Table 27 ).
• The boundary value is expressed in kilobytes. The boundary value depends on volume emulation
types and RAID levels (see Table 28 ).
• If the CV capacity unit is blocks:
To calculate the CV's user area capacity, use the following formula. The resulting user area capacity
is expressed in kilobytes.
user-specified-CV-capacity ÷ 2
NOTE:
The user-specified CV capacity is expressed in blocks.
To calculate the CV's entire capacity, use the following formula. The resulting entire capacity is
expressed in blocks. To convert the resulting entire capacity into megabytes, divide this capacity
by 2,048.
