About LUN Zoning

Logical unit number (LUN) zoning is a feature specific to switches in the Cisco MDS 9000 Family.
Caution LUN zoning can only be implemented in Cisco MDS 9000 Family switches. If LUN zoning is
implemented in a switch, you cannot configure the interop mode in that switch.
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.
When LUN 0 is not included within a zone, then, as per standards requirements, control traffic to LUN
Note
0 (for example, REPORT_LUNS, INQUIRY) is supported, but data traffic to LUN 0 (for example,
READ, WRITE) is denied.
•
•
Unzoned LUNs automatically become members of the default zone.
