The availability of a disk type depends on the disk array.
The devices are defined to the host as SCSI disk devices, even though the
interface is Fibre Channel.
The device capacity can sometimes be changed by the BIOS or host adapter
board. This may make actual capacity different from that listed in the table.
The number of blocks for a CVS volume is calculated as follows:
# of blocks = (# of cylinders) × (# of heads) × (# of sectors per track)
Example 1: 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 2: For an OPEN-V CVS volume with capacity = 49 MB:
# of blocks = (53 cylinders–see Note 5) × (15 heads) × (128 sectors per
track) = 101760
The number of cylinders for a CVS volume is calculated as follows (↑...↑
means that the value should be rounded up to the next integer):
OPEN-3/8/9/E: The number of cylinders for a CVS volume =
# of cylinders = ↑ (capacity (MB) specified 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) specified by user) × 16/15 ↑
Example: For an OPEN-V CVS volume with capacity = 49 MB:
# of cylinders = ↑49 × 16/15↑ = ↑52.26↑ (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
