3. The number of cylinders of a Logical Unit Size Expansion (LUSE)
composed of OPEN-x CVS volumes corresponds to the capacity
specified by the SVP or the remote console. CVS size of
OPEN-x is specified by the capacity (megabyte), not by the number of
cylinders. The number of cylinders of the OPEN-x CVS volume can be
obtained by the following calculation (↑ ↑ means round up to integer):
The number of cylinders = ↑ (specified capacity in megabytes from
SVP or remote console) × 1,024 / 720 ↑ × n
where n is the number of concatenated volumes for LUSE.
Example When 37 MB is specified for the OPEN-3 CVS volume and the four
volumes are concatenated, the number of cylinders of the OPEN-3
CVS can be calculated as follows:
↑ 37 × 1,024 / 720↑ × 4 = ↑ 52.62↑ × 4 = 53 × 4 = 212
The LUSE for the OPEN-3 CVS volume has 212 cylinders.
