Note 1:

The availability of an emulation depends on the disk array.

Note 2:

Thedevicesaredeﬁned 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 B IOS 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 sec

tors 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
