This document describes the features, issues, and deployment guidelines for the Cisco MDS NX-OS software for use on the Cisco MDS 9000 Series Switches.

Note:       

      Cisco MDS 9000 NX-OS 9.4(2) software release is affected by software defect CSCwk14579, which may cause authentication failures after the upgrade, only in the case where TACACS is used as authentication protocol. If you are using TACACS and are considering an upgrade to Cisco MDS 9000 NX-OS 9.4(2), we are recommending to postpone the upgrade. A future release, available shortly, will contain the fix for this issue. If the upgrade to Cisco MDS 9000 NX-OS 9.4(2) is required and TACACS is being used as the authentication protocol, then a workaround is available. Please review the workaround section in the software defect CSCwk14579.

Initial Release

Introduction

The Cisco MDS 9000 Series of Multilayer Directors and Fabric Switches provide best-in-class high availability, scalability, security, and management that enables to deploy high-performance storage area networks. Layering a rich set of intelligent features onto a high-performance switch fabric, the Cisco MDS 9000 Series has the flexibility to fit small deployments and to address the stringent requirements of large data center storage environments: high availability, security, scalability, sustainability, ease of management, and seamless integration of new technologies.

About Software Images

The Cisco MDS NX-OS operating system is shipped with the Cisco MDS 9000 Series Switches. The Cisco MDS NX-OS software consists of two images: the kickstart image and the system image. These images can be upgraded or downgraded to different versions. The versions of both images must match for the system to boot.

Each model of the Cisco MDS switch has unique kickstart and system images. For more information on the image names for each Cisco MDS switch, see the Cisco MDS 9000 NX-OS Software Upgrade and Downgrade Guide, Release 9.x.

To download the new Cisco MDS 9000 Series Switches NX-OS software, go to the Storage Networking Software download website at https://software.cisco.com/download/find/MDS.

About Firmware Images

Cisco MDS 9000 Series Switches contain a number of hardware components with updatable firmware. The Transceiver Firmware bundle contains updates for various port transceivers. The EPLD Firmware bundle contains updates for programmable logic devices in the system.

These updates can be disruptive and so are not part of the Cisco NX-OS software image. They are released with every Cisco NX-OS release but do not frequently contain changes. Refer to the specific Release Notes for any recommended fixes.

For more information on Transceiver Firmware, see the Cisco MDS 9000 Series Transceiver Firmware Release Notes, Release 9.4(2).

For more information on EPLD bundles, see the Cisco MDS 9000 Series EPLD Release Notes, Release 9.4(2).

Choosing Between Cisco MDS NX-OS Open Systems Releases

Cisco uses release numbering to indicate the maturity of a Cisco MDS NX-OS release train. Cisco MDS NX-OS major versions are incremented when significant software features or hardware support are added. Because of the focus on new features and hardware, all bugs may not yet have been fixed. After an initial release, minor version numbers of the release train are incremented as bugs are resolved, and minor feature enhancements and security patches are integrated. This provides increased stability to the new features and updated security.

For Cisco recommended MDS NX-OS releases for each type of hardware, see Recommended Releases for Cisco MDS 9000 Series Switches document.

Components Supported

For information on supported software and hardware components, see Cisco MDS 9000 Series Compatibility Matrix.

IBM FICON Qualification Status

Cisco MDS NX-OS Release 9.4(2) is not IBM FICON qualified. For more information on releases that are IBM FICON qualified, see Cisco MDS 9000 NX-OS and SAN-OS Software Release Notes.

Upgrade and Downgrade Paths

The following sections provides information about nondisruptive upgrade and downgrade paths for Cisco MDS NX-OS Release 9.4(2). For guidelines that are recommended for upgrading or downgrading Cisco MDS NX-OS software images, see the Cisco MDS 9000 NX-OS Software Upgrade and Downgrade Guide, Release 9.x.

Unsupported Features

MD5 Hash in FCSP

From Cisco MDS NX-OS Release 9.4(2), support for the MD5 hash algorithm in Fibre Channel Security Protocol (FSCP) has been removed as it is no longer considered secure. The default hash algorithm has been changed to SHA1.

10G and 40G FCoE linecards

From Cisco MDS NX-OS Release 9.4(2), the following FCoE linecards are no longer supported:

·     DS-X9824-960K9 – MDS 9700 24-port 40-Gbps FCoE Switching Module

For more information, see Cisco MDS 9700 Series Multilayer Directors Hardware Installation Guide.

SDV feature

Cisco MDS NX-OS Release 9.3(2) and later releases do not support Cisco SAN device virtualization (SDV).

Traditional and Smart Licensing Version 1.0 Licenses

Cisco MDS NX-OS Release 9.2(2) and later releases does not support installation of Product Authorization Key (PAK) or Smart Licensing version 1.0 licenses. Licenses are now managed through Smart License using Policy (SLP).

For more information such as how to migrate licenses, see Smart Licensing Using Policy chapter in Cisco MDS 9000 Series Licensing Guide, Release 9.x.

Python 2

Support for Python 2 is deprecated from Cisco MDS NX-OS Release 9.2(2). Python 3 remains supported instead. Python 2 scripts should be checked for compatibility with Python 3 to ensure they continue to function as expected.

For more information, see the Python API chapter in the Cisco MDS 9000 Series Programmability Guide, Release 9.x.

Zoning Features

LUN zoning, read-only zones, and broadcast zones are no longer supported.

If these features are already configured, completely remove all the configurations that include these features before attempting to boot any module. In addition, you cannot configure these features after you bring up any module.

XRC Acceleration License

From Cisco MDS NX-OS Release 8.1(1a), the Cisco Extended Remote Copy (XRC) acceleration license is obsoleted on Cisco MDS 9000 Series Switches due to improvements in the mainframe XRC feature.

Virtual Router Redundancy Protocol (VRRP)

From Cisco MDS NX-OS Release 8.3(1) and later, the VRRP feature is not supported on Cisco MDS 9000 Series Switches.

Data Encryption Standard (DES) for SNMP

From Cisco MDS NX-OS Release 8.5(1), AES-128 is the default encryption mechanism for SNMPv3. DES encryption for SNMP is supported only for DES users who upgrade from previous releases to Cisco MDS NX-OS Release 8.5(1). Ensure that you delete all the SNMPv3 users configured with DES encryption before upgrading to Cisco MDS NX-OS Release 8.5(1) and later releases. Any downgrades from Cisco MDS NX- OS Release 8.5(1) will be restricted if any of the SNMPv3 users have DES encryption configured as the privacy protocol. All such users will either need to be deleted or reconfigured to use no privacy protocol or AES128 encryption before downgrading.

For more information, see Cisco MDS 9000 Series System Management Configuration Guide, Release 9.x.

Fabric Performance Impact Notifications (FPIN)

·       FPIN is not supported on switches that are operating in NPV mode.

·       FPIN notifications for oversubscription-based congestion are not supported.

FCWA, XRC, DMM, SME

FCWA, XRC, DMM, and SME features are not supported from Release 8.x.

SAN Extension Tuner

SAN Extension Tuner (SET) is not supported on Cisco MDS 9220i switches in Cisco MDS NX-OS Release 8.5(1) or later.

Fibre Channel Read Diagnostic Parameters

Fibre Channel RDP querying is not supported on NP, Port Channel, or FCoE links.

Slow Drain Detection and Congestion Isolation

ER_RDY is not supported on FC interfaces running at 10 Gbps.

FCIP Support

·     In Cisco MDS NX-OS Release 9.2(2) or later releases, simultaneous use of IVR and FCIP Write Acceleration features is not supported on FCIP tunnels configured on Cisco MDS 9700 Director switches.

·     On Cisco MDS 24/10 Port SAN Extension Module, configuring multiple FSPF equal cost paths (ECMP) port channels with FCIP members in the same VSAN is not a valid configuration. If this is configured, then the traffic flows through only one of the port channels.

iSCSI Support

iSCSI is not supported on Cisco MDS 9700 Directors with Cisco MDS 24/10 port SAN Extension Modules and Cisco MDS 9220i multiservice fabric switch.
