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 Series 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
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:
