Notes for Table 1 Through Table 5
1. The value of pc is calculated as follows:
pc = nc * nt * ns
The nc of OPEN-K/3/8/9/E CVS corresponds to the capacity specified by SVP or
remote console.
The CVS size of OPEN-K/3/8/9/E is specified by capacity (megabyte), not by
number of cylinders.
The number of cylinders of an OPEN-K/3/8/9/E CVS volume can be obtained by
the following calculation (↑↑ means round up to integer).
Number of cylinders = ↑(specified capacity in megabytes from SVP or
remote console) × 1,024 / 720↑
When 37 MB is specified for an OPEN-3 CVS volume from SVP, the number of
cylinders of the OPEN-3 CVS can be calculated as follows:
37 × 1,024 / 720 = 52.62
↑52.62↑ = 53
The OPEN-3 CVS volume has 53 cylinders.
2. The value of pa must be equal to or more than 131,072.
3. The number of cylinders of a Logical Unit Size Expansion (LUSE) composed of
OPEN-K/3/8/9/E CVS volumes corresponds to the capacity specified by the SVP
or the remote console. CVS size of OPEN-K/3/8/9/E is specified by the capacity
(megabyte), not by the number of cylinders. The number of cylinders of the
OPEN-K/3/8/9/E CVS volume can be obtained by the following calculation
(↑↑ means round up to integer):
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.
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.
