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 as well as to addresses the stringent requirements of large data center storage environments: high availability, security, scalability, 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 Cisco MDS switch has unique kickstart and system images. For more information on the image names for each Cisco MDS switch, see Cisco MDS 9000 NX-OS Software Upgrade and Downgrade Guide, Release 9.x.

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

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 defects may not yet have been fixed. After an initial release, minor version numbers of the train are incremented, and only security patches and defect fixes are added, providing better stability to the new features and updated security.

For information about other releases, refer to Release Notes on Cisco MDS 9000 NX-OS and SAN-OS Software documentation page. For Cisco recommended MDS NX-OS releases for each type of hardware, see Recommended Releases for Cisco MDS 9000 Series Switches.

Components Supported

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

FICON

Cisco MDS NX-OS Release 9.2(2) is not IBM FICON qualified. For more information on releases that are IBM FICON qualified, see http://www.cisco.com/c/en/us/support/storage-networking/mds-9000-nx-os-san-os-software/products-release-notes-list.html.

Upgrading Cisco MDS NX-OS Software Image

This section lists the guidelines recommended for upgrading Cisco MDS NX-OS software image and includes the following topics:

      General Upgrading Guidelines

      Open Systems Nondisruptive Upgrade Paths

For detailed instructions for performing a software upgrade using Cisco DCNM, see Cisco DCNM Release Notes.

General Upgrading Guidelines

This section lists the general guidelines for performing a software upgrade:

      Install and configure dual supervisor modules before the upgrade.

      Issue the show install all impact upgrade-image command to determine if the upgrade will be nondisruptive.

      Some features are impacted whether an upgrade is disruptive or nondisruptive:

    Fibre Channel Ports: Fibre Channel ports can be nondisruptively upgraded without affecting traffic on the ports. See Open Systems Nondisruptive Upgrade Paths for all MDS NX-OS releases.

    Fibre Channel over Ethernet (FCoE) Ports: FCoE ports can be nondisruptively upgraded without affecting traffic on the ports. See Open Systems Nondisruptive Upgrade Paths for all MDS NX-OS releases.

    IP Storage (IPS) Ports: Traffic on IPS ports on Cisco MDS 9220i and Cisco MDS 24/10-Port SAN Extension Modules is disrupted during an upgrade or downgrade. Nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration may occur. If supported, iSCSI initiators connected to the IPS ports lose connectivity to iSCSI targets while the upgrade is in progress.

Note:      In addition to these guidelines, review the information in Limitations and Restrictions before a software upgrade to determine if a feature may possibly behave differently following the upgrade.

    To upgrade or downgrade to a Cisco MDS NX-OS release version, the same release version of the kickstart and system images in the install all command must be used.

    If you are upgrading Cisco MDS 9700 Series Directors from Cisco MDS NX-OS Release 8.3(1), Release 8.3(2), Release 8.4(1), or Release 8.4(1a) to Release 8.4(2) or later, ensure that you perform a switchover before upgrading. For more information, see CSCvt87216.

    If you are upgrading from a release prior to Cisco MDS NX-OS Release 9.2(1) or later, ensure that you use the clear logging onboard txwait command after upgrading. Otherwise, the file will be automatically deleted and recreated at the new file size when the file size exceeds 512 KB. For more information, see Cisco MDS 9000 Series Interfaces Configuration Guide, Release 9.x.

    If you are upgrading from Cisco MDS NX-OS Release 8.5(1) to Release 9.2(1) or later, ensure that you disable the Fabric Performance Monitor (FPM) feature using the no feature fpm command before upgrading. After the switch is upgraded to Release 9.2(1) or later, FPM can be enabled again via the feature fpm command.

Open Systems Nondisruptive Upgrade Paths

The software upgrade information in this section applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and intelligent services traffic.

      General Downgrading Guidelines

      Open Systems Nondisruptive Downgrade Paths

General Downgrading Guidelines

Follow these general guidelines before performing a software downgrade:

      Disable all features that are not supported by the downgrade release. Use the show incompatibility system downgrade-image command to determine the features that needs to be disabled.

      Use the show install all impact downgrade-image command to determine if the downgrade is nondisruptive.

      Some features are impacted whether a downgrade is disruptive or nondisruptive:

    Fibre Channel Ports: Fibre Channel ports can be nondisruptively downgraded without affecting traffic on the ports. See Open Systems Nondisruptive Downgrade Paths for all MDS NX-OS releases.

    Fibre Channel over Ethernet (FCoE) Ports: FCoE ports can be nondisruptively downgraded without affecting traffic on the ports. See Open Systems Nondisruptive Downgrade Paths for all MDS NX-OS releases.

    IPStorage Ports: Traffic on IPStorage ports on MDS 9220i, MDS 9250i, and MDS 24/10-Port SAN Extension Modules is disrupted during an upgrade or downgrade. Nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration may occur. If supported, iSCSI initiators that are connected to the IPStorage ports lose connectivity to iSCSI targets while the upgrade is in progress.

    I/O Acceleration: Traffic that uses I/O Acceleration is disrupted during a downgrade.

      Any hardware that is not supported by the downgrade release version will be powered down when the downgrade release starts running. Power off and or remove any unsupported components before downgrading. For more information about supported hardware see Cisco MDS 9000 Series Compatibility Matrix.

      If you are downgrading from this release to a release before Cisco MDS NX-OS Release 9.2(1), ensure that you run the clear logging onboard txwait command after the downgrade is complete. Otherwise, logging to the OBFL TxWait file may cease with an error. For more information, see the Cisco MDS 9000 Series Interfaces Configuration Guide, Release 9.x.

New Hardware Features

There are no new hardware features in Cisco MDS NX-OS Release 9.2(2).

New Software Features

SAN Analytics

The SAN Analytics feature has been enhanced. Support was added for the Cisco MDS 9700 48-Port 64-Gbps Fibre Channel Switching Module. Additionally, new flow metrics were introduced.

For more information, see Cisco MDS 9000 Series SAN Analytics and SAN Telemetry Streaming Configuration Guide, Release 9.x.

Transceiver Streaming

Streaming of transceiver information to a SAN Telemetry Streaming receiver was introduced to allow monitoring and troubleshooting of transceiver issues. As a result, the transceiver and transceiver_peer options have been added to the telemetry path command.

For more information, see Cisco MDS 9000 Series SAN Analytics and SAN Telemetry Streaming Configuration Guide, Release 9.x.

Smart Licensing Using Policy

The Smart Licensing Using Policy (SLP) feature was introduced. This is an enhanced version of Smart Licensing which provides more flexibility in managing hardware and software licenses across fabrics. Older PAK and Smart Licensing licenses will no longer be supported and will be automatically converted to the new model as of this release. This occurs when you are in online mode or when you upload the RUM report to CSSM when in offline mode.

For more information, see Cisco MDS 9000 Series Licensing Guide, Release 9.x.

Secure Remote System Message Logging

Support was added for CFS distribution of the existing remote logging server secure option. CFS distribution allows the secure option to be configured on one switch and easily distributed to other switches in the same fabric via the logging distribute command.

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

IPSec Licensing for Cisco MDS 9220i Switch

The IPsec feature is now included in the default feature set and does not require an ENTERPRISE_PKG license on the Cisco MDS 9220i Fabric Switch.

For more information, see:

      Cisco MDS 9000 Series Security Configuration Guide, Release 9.x

      Cisco MDS 9000 Series Licensing Guide, Release 9.x.

Secure Erase

The Secure Erase feature was introduced. This feature allows erasure of all customer data from a Cisco MDS module or fabric switch. This returns it to the same state it was when initially shipped from the factory. As a result, the factory-reset command was introduced.

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

Transceiver Authenticity Validation

Transceiver authenticity validation was added to verify the serial number, vendor name, and other parameters programmed in transceivers. This allows validation that the transceiver is an authentic Cisco compliant unit.

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

Unsupported Features

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.

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

Python 2

From Cisco MDS NX-OS Release 9.2(2), Python 2 is deprecated. Python 3 continues to be 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 Python API chapter in Cisco MDS 9000 Series Programmability Guide, Release 9.x.

Data Mobility Manager

From Cisco MDS NX-OS Release 8.1(1), the Cisco MDS Data Mobility Manager feature is not supported on Cisco MDS 9000 Series Switches.

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) Encryption 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.

Limitations and Restrictions

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 Enhancements

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

DIRL and FPIN

DIRL and FPIN are not supported on switches that are operating in the Cisco NPV mode.

FPIN Notifications
