Note 1:
The availability of a disk type depends on the disk array.
Note 2:
The devices are defined to the host as SCSI disk devices, even though the interface is
Fibre Channel.
Note 3:
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.
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 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 ↑
