Notes for Table 1 Through
1. The value of pc is calculated as follows:
pc = nc ∗ nt ∗ ns
The nc of OPEN-x CVS corresponds to the capacity specified by SVP
or remote console.
The CVS size of OPEN-x is specified by capacity (megabyte), not by
number of cylinders.
The number of cylinders of an 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 ↑ .
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.
