Note 1:

The availability of an emulation 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 ↑
