Step 4
Click either the WWN or FCID radio button from the Zone By options to create a LUN-based zone.
Step 5 Check the LUN check box and click the browse button to configure LUNs.
Step 6 Click Add to add this LUN-based zone.
Assigning LUNs to Storage Subsystems
LUN masking and mapping restricts server access to specific LUNs. If LUN masking is enabled on a
storage subsystem and if you want to perform additional LUN zoning in a Cisco MDS 9000 Family
switch, obtain the LUN number for each host bus adapter (HBA) from the storage subsystem and then
configure the LUN-based zone procedure provided in the “Configuring a LUN-Based Zone” section on
page 30-40.
Note Refer to the relevant user manuals to obtain the LUN number for each HBA.
Caution If you make any errors when assigning LUNs, you might lose data.
About Read-Only Zones
By default, an initiator has both read and write access to the target's media when they are members of
the same Fibre Channel zone. The read-only zone feature allows members to have only read access to
the media within a read-only Fibre Channel zone.
You can also configure LUN zones as read-only zones.
Any zone can be identified as a read-only zone. By default all zones have read-write permission unless
explicitly configured as a read-only zone.
Follow these guidelines when configuring read-only zones:
• If read-only zones are implemented, the switch prevents write access to user data within the zone.
• If two members belong to a read-only zone and to a read-write zone, the read-only zone takes
priority and write access is denied.
• LUN zoning can only be implemented in Cisco MDS 9000 Family switches. If LUN zoning is
implemented in a switch, you cannot configure interop mode in that switch.
