where
• the value enclosed in ceil( ) must be rounded up to the nearest whole number.
• user-specified-CV-capacity is the capacity of the user area in a CV expressed in
cylinders.
• boundary-value is expressed in kilobytes. The boundary-value depends on volume
emulation types and RAID levels (see “Boundary values for RAID levels (Enhanced mode on
SATA drives)” (page 32)). If the data protection level is set to the Enhanced mode on a SATA
drive, the boundary value depends on volume emulation types and RAID levels (see “Boundary
values for RAID levels (other than Enhanced mode on SATA drives)” (page 32)).
• capacity-of-a-slot is expressed in kilobytes. The capacity of a slot value depends on
volume emulation types (see “Capacity of a slot” (page 32)).
• The resulting CV capacity is expressed in megabytes.
When calculating the size of a mainframe volume, note the following:
• In 3390-A, boundary-value is always 974,400 KB (1,120 cylinder) regardless of the RAID
level.
• In 3390-A, if a value is specified in Remote Web Console in the Create LDEVs window that
exceeds 65,520 cylinders, the value is corrected to multiples of 1,113 cylinders. For instance,
if 65,521 is specified, 65,667 which is 59 times 1,113 cylinders appears.
• In 3390-V, the value specified in the Create LDEVs window is corrected to multiples of 44.8
cylinders (38,976 KB). The number of cylinders that is truncated value after the decimal point
appears. For instance, if 10,000 is specified, 10,035 appears. This value is truncated after
the decimal point of 10,035.2 that is 224 times 44.8 cylinders.
Calculating OPEN-V volume size (CV capacity unit is blocks)
To calculate the user area capacity of a CV whose capacity unit is defined as blocks:
ceil(user-specified-CV-capacity / 2)
where
• the value enclosed in ceil( ) must be rounded up to the nearest whole number.
• user-specified-CV-capacity is expressed in blocks.
• The resulting user area capacity is expressed in kilobytes.
To calculate the entire capacity of a CV:
ceil(user-specified-CV-capacity / (boundary-value * 2)) * (boundary-value * 2)
where
• the value enclosed in ceil( ) must be rounded up to the nearest whole number.
• user-specified-CV-capacity is expressed in blocks.
• boundary-value is expressed in kilobytes. The boundary value depends on volume emulation
types and RAID levels (see “Boundary values for RAID levels (other than Enhanced mode on
SATA drives)” (page 32)). If the data protection level is set to the Enhanced mode on a SATA
