2
Select a host to make the channel zoning command available.
3
Select a blade in the last of column of the FC Host dialog box, and then select Channel Zoning.
4
To restrict access, clear the checkmark in the cell where the target port and the initiator channel meet.
All combinations are possible with one exception. If a FC port is set to target & initiator mode, it will
appear in both the horizontal row and vertical column. The FC port will not be allowed access to itself,
however, in order to prevent "ghosting." Ghosting is a condition where hosts can see storage in two
places.
Bear in mind that an entire channel is zoned when the cell is checked. This effects any host that may
be accessing the I/O blade.

SCSI Host
During device discovery, a particular partition or drive may map to a higher LUN space than is optimal for a
particular application. The SCSI Host feature allows you to create a virtual private remapping of available
LUNs for a specific SCSI channel-attached host. With it, you can make devices appear to the host as if they
were at lower LUNs in order to optimize system performance.
Use SCSI Host to map partitions when a SCSI channel host is connected to
Note
the MCB SCSI port.
Depending upon host operating system constraints, it may be necessary to reboot or reconfigure the host
as a result of device map changes resulting from the use of SCSI Host.
To create SCSI Host LUN mapping assignments
1
Select Setup > Device > Access > SCSI Host.
The SCSI Host dialog box is displayed.
2
Select a SCSI port to configure.
In the SCSI Host dialog box pictured in the example, there is only one SCSI port available, and it is on the
MCB.
3
With the port selected, select LUN Mapping.
The SCSI Host Map dialog box is displayed.
4
Drag the partitions that you want the SCSI host to manage from the Device column to the ID/LUN/
Device column.
5
Drag and drop the devices from the Device column to the appropriate LUN assignment in the ID/LUN/
Device column.
The right column of the SCSI host map dialog box, labeled Device, lists all available devices. The ID/
LUN/Device column on the left provides map space for IDs 0-15 associated with the selected SCSI
Channel, and LUNs 0-7 associated with each ID. Drag and drop devices from the Device column into
the boxes associated with particular LUN assignments in the ID/LUN/Device column.
6
Select OK to save the mapping.
