Notes for disk parameters
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 .
Example
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-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 (megabytes), 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.
