Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(8b)

OL-27554-06

New Features in Cisco MDS NX-OS Release 5.2

• Once you enable smart zoning, you cannot add a switch to the fabric that does not support smart

zoning.

• Before downgrading from a switch that has smart zoning enabled, disable smart zoning on all

VSANs; otherwise, the downgrade is disruptive.

Note Smart zoning is not supported in a fabric if DMM, IOA, or SME is running. Do not enable smart zoning

on a switch where DMM, IOA, or SME is configured.

For additional information on how to implement and configure Smart Zoning, see the Cisco MDS 9000

Fabric Configuration Guide.

Storage Media Encryption Features

Cisco NX-OS Release 5.2(6) includes the following enhancements to Cisco Storage Media Encryption

(SME) Disk:

–

SME Disk now supports greater than 2 TB LUNs for both signature and non-signature mode.

–

SME Disk signature mode allows snapshots of a crypto LUN across key change operations.

–

SME Disk signature mode automatically recognizes snapshots that are exposed to the host,

based on the media signature.

–

SME Disk now supports Master Key Rekey (MKR) on a cluster for both signature and

non-signature mode.

These enhancements require Cisco NX-OS Release 5.2(6) and Cisco DCNM Release 6.1(1a). For more
