NOTE:
•
Round up the value enclosed by two up arrows ( ) to the nearest whole number.
• The user-specified CV capacity is expressed in cylinders.
• The management area capacity is expressed in cylinders (see Table 25 ).
• The boundary value is expressed in kilobytes. The boundary value depends on volume emulation
types and RAID levels (see
Table 27 ).
• The slot capacity is expressed in kilobytes. The slot capacity depends on the volume emulation
types (see
Table 28 ).
Calculating CV capacity for open systems
When creating a CV, you can specify the CV's capacity. However, there is a margin of error between
the user-specified CV capacity and the actual CV capacity.
This section explains how to calculate the user area capacity and the entire capacity. The term “user
area capacity” refers to the capacity of areas in a CV that can contain user data.
If the emulation type is OPEN-V
The methods for calculating the CV's user area capacity and the entire capacity vary depending on
the CV capacity unit specified when creating the CV.
• If the CV capacity unit is megabytes (MB):
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 x 1024 \ 64 \ 15 x 64 x 15
NOTE:
• Round up the value enclosed by two up arrows ( ) to the nearest whole number.
• The user-specified CV capacity is expressed in megabytes.
To calculate the CV's entire capacity, use the following formula. The resulting entire capacity is
expressed in megabytes:
user-area-capacity \ boundary-value x 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 27 ).
• If the CV capacity unit is cylinders (Cyl):
