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" topic.

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.
