Example: For a CVS LUSE volume with capacity = 37 MB and n = 4
# of cylinders = ↑ 37 × 1024/720↑ × 4 = ↑ 52.62↑ × 4 = 53 × 4 = 212
OPEN-V: The number of cylinders for a CVS LUSE volume =
# of cylinders = ↑ (capacity (MB) specified by user) × 16/15 ↑ × n
Example: For an OPEN-V CVS LUSE volume with capacity = 49 MB and
n = 4
# of cylinders = ↑ 49 × 16/15↑ × 4 = ↑ 52.26↑ × 4 = 53 × 4 = 212
The capacity of an OPEN-3/8/9/E CVS volume is specified in MB, not
number of cylinders. The capacity of an OPEN-V CVS volume can be
specified in MB or number of cylinders. You set the volume size using the
LUN Configuration Manager or Command View software.
The following tables present parameter values for specific Open system types.
