44 Volume Management for the XP10000/XP12000

• The user-specified CV capacity is expressed in megabytes.

To calculate the entire capacity of a CV, use the following formula. The resulting entire capacity is

expressed in megabytes:

↑ user-area-capacity ÷ boundary-value ↑ × boundary-value ÷ 1024

NOTE:

• Round up the value enclosed by two up arrows (↑) to the nearest whole number.

• The user area capacity is expressed in kilobytes.

• The boundary value is expressed in kilobytes. The boundary value depends on volume

emulation types and RAID levels (see Table 19 on page 46).

• If the unit for CV capacity is cylinders (Cyl):

To calculate the user area capacity of a CV, use the following formula. The resulting user area capacity

is expressed in kilobytes.

user-specified-CV-capacity × 64 × 15

NOTE: The user-specified CV capacity is expressed in cylinders.

To calculate the entire capacity of a CV, use the following formula. The resulting entire capacity is

expressed in megabytes.

↑ user-area-capacity ÷ boundary-value ↑ × boundary-value ÷ 1024

NOTE:

• Round up the value enclosed by two up arrows (↑) to the nearest whole number.

• The user area capacity is expressed in kilobytes.

• The boundary value is expressed in kilobytes. The boundary value depends on volume

emulation types and RAID levels (see Table 19 on page 46).

• If the unit for CV capacity is “block”:

To calculate the user area capacity of a CV, 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 entire capacity of a CV, 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.

↑ user-specified-CV-capacity ÷ (boundary-value × 2) ↑ × (boundary-value × 2)

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 19 on page 46).
