5. The value of [Note 5] is the number of cylinders of OPEN-K/3/8/9/E CVS
corresponding to the capacity specified by the SVP or the remote console. The CVS
size of OPEN-K/3/8/9/E is specified by capacity in megabytes, not by the number
of cylinders. The number of cylinders in an OPEN-K/3/8/9/E CVS volume can be
calculated as follows (↑↑ means round up to integer):
Number of cylinders = ↑(specified capacity (MB) from SVP or remote
console) × 1024 / 720↑
When 37 MB is specified for OPEN-3 CVS volume from the SVP, the number of
cylinders of the OPEN-3 CVS can be calculated as follows (↑↑ means round up to
integer):
37 × 1024/720 = 52.62
↑52.62↑ = 53
The OPEN-3 CVS volume has 53 cylinders.
6. The value of [Note 6] is the number of cylinders of LUSE composed of OPEN-K/
3/8/9/E CVS volumes corresponding to the capacity specified by SVP or remote
console. The CVS size of an OPEN-K/3/8/9/E device is specified by capacity in
megabytes, not by the number of cylinders. To calculate the number of cylinders of
OPEN-K/3/8/9/E CVS volumes (↑↑ means round up to integer):
Number of cylinders = ↑ (specified capacity (MB) from the SVP or the
remote console) × 1024 / 720 ↑ × n
where n = the number of concatenated volumes for LUSE
When an OPEN-3 CVS volume is specified as 37 MB and the volumes are
concatenated, calculate the number of cylinders of the OPEN-3 CVS as follows:
↑37 × 1024/720↑ × 4 = ↑52.62↑ × 4 = 53 × 4 = 212
The LUSE for OPEN-3 CVS volume has 212 cylinders.
