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 c apacity can sometimes be changed by the BIOS or host a dapter board.
This may m ake actual capacity different from that listed in the table.
Note 4:
The number
of cylinders for a CVS volume is calculated as follows (↑… ↑ means that the
valueshouldberoundeduptothenextinteger):
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↑
(ro
unded up to next integer) = 53 cylinders
