208 Configuring the Library
Channel Zoning
You can use channel zoning to restrict host access to specific ports on the FC I/O blade. In most cases,
however, channel zoning should be left at default settings. Use the procedure below if you need to configure
channel zoning as part of your initial library setup.
Configuring FC Channel Zoning
1 Click Setup→ Device→ Access→ Channel Zoning.
The Channel Zoning configuration box appears.
2 Select a blade and then click Configure.
3 To restrict access, clear the check mark 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.
Be aware that an entire channel is zoned when the cell is checked. This effects any host that may be
accessing the FC I/O blade.
4 Click OK to save your settings.
