Example
For an OPEN-V CVS volume with capacity = 49 MB:
# of cylinders =
(rounded up to next integer) = 53 cylinders
OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume = # of cylinders = (capacity
(MB) specified by user) × 1024/720 × n
Example
For a CVS LUSE volume with capacity = 37 MB and n = 4:
# of cylinders =
OPEN-V: The number of cylinders for a CVS LUSE volume = # of cylinders = (capacity (MB)
specified by user) × 16/15 × n
Example
For an OPEN-V CVS LUSE volume with capacity = 49 MB and n = 4:
# of cylinders =
7
The capacity of an OPEN-3/8/9/E CVS volume is specified in MB, not number of cylinders. The
capacity of an OPEN-V CVS volume can be specified in MB or number of cylinders. You set the
volume size using XP Remote Web Console or P9000 or XP Command View Advanced Edition
Software.
