Note 4:
The number of blocks for a CVS volume is calculated as follows:
# of blocks = (# of cylinders) × (# of heads) × (# of sectors per track)
Example
For an OPEN-3 CVS volume with capacity = 37 MB:
# of blocks = (53 cylinders–see Note 5) × (15 heads) ×
(96 sectors per track) = 76320
Example
For an OPEN-V CVS volume with capacity = 49 MB:
# of blocks =
(53 cylinders–see Note 5) × (15 heads) ×
(128 sectors per track) = 101760
Note 5:
The number of c
ylinders for a CVS volume is calculated as follows ( means that the value should be
roundeduptothenextinteger):
OPEN-3/8/9/E: ThenumberofcylindersforaCVSvolume=#ofcylinders= (capacity (MB) specied
by user) × 1024/720
Example
For an OPEN-3 CVS volume with capacity = 37 MB:
# of cylinders = 37 × 1024/720 = 52.62
(rounded
up to next integer) = 53 cylinders
OPEN-V: The number of cylinders for a CVS volume = # of cylinders = (capacity (MB) specied by
user) × 16/15
Example
For an OPEN-V CVS volume with capacity = 49 MB:
# of cylinders = 49 × 16/15 = 52.26
(round
ed up to next integer) = 53 cylinders
OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume = # of cylinders = (capacity (MB)
specied b
yuser)×1024/720 ×n
Example
For a CVS LUSE volume with capacity = 37 MB andn=4:
# of cylinders = 37 × 1024/720 ×4=52.62×4=53×4=212
OPEN-V: The number of cylinders for a CVS LUSE volume = # of cylinders = (capacity (MB) specied
by user) × 16/15 ×n
Example
For an OPEN-V CVS LUSE volume with capacity = 49 MB andn=4:
# of cylinders = 49 × 16/15 ×4=52.26×4=53×4=212
Note 6:
The capacity of an OPEN-3/8/9/E CVS volume is specied in MB, not number of cylinders. The
capacity of an OPEN-V CVS volume can be specied in MB or numb er of cylinders. You set the volume
size using Remote Web Console, Command View or Command View XP Advanced Edition.
