Importing from one switch and exporting from another switch can lead to isolation again.
LUN Zoning
Logical unit number (LUN) zoning is a feature specific to switches in the Cisco MDS 9000 Family.
LUN zoning can be implemented in Cisco MDS 9000 Family switches running Cisco MDS SAN-OS
Release 1.2(x) or above.
A storage device can have multiple LUNs behind it. If the device port is part of a zone, a member of the
zone can access any LUN in the device. With LUN zoning, you can restrict access to specific LUNs
associated with a device.
