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 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 the Cisco MDS 9000 NX-OS Software Upgrade and Downgrade Guide, Release 8.x.

To download new Cisco MDS 9000 Series software, including Cisco MDS NX-OS and Cisco NDFC 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.

Details about the new features and hardware supported by Cisco MDS NX-OS Release 8.4(2f) can be found in the New Hardware and Software Features section. For information about other releases, refer to the Release Notes on the Cisco MDS 9000 NX-OS and SAN-OS Software documentation page.

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

Components Supported

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

FICON

Cisco MDS NX-OS Release 8.4(2f) 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 NDFC, see Cisco NDFC 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 the “Open Systems Nondisruptive Upgrade Paths” section 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 the “Open Systems Nondisruptive Upgrade Paths” section for all MDS NX-OS releases.

    IP Storage (IPS) Ports: Traffic on IPS ports on Cisco MDS 9250i, 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.

    In addition to these guidelines, review the information in the "Limitations and Restrictions" section 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.

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.

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

     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.

     The following features are impacted during a downgrade, whether it is a nondisruptive downgrade or a disruptive downgrade:

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

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

o    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.

Find the MDS NX-OS image that you want to downgrade to in Table 2 and follow the steps in the order specified to perform the downgrade.

Note:       The software downgrade information in the below tables applies only to Fibre Channel switching traffic. Downgrading system software disrupts IP and intelligent services traffic.

     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 the Cisco MDS 9000 Series Compatibility Matrix.

     If you are downgrading to Cisco MDS NX-OS Release 8.1(x), Release 8.2(x), Release 8.3(x), or Release 8.4(1x) from Release 8.4(2x) and if smart license and VSAN policy for a role are configured, ensure that you disable Smart Licensing or disable VSAN policy for only the role before downgrading or performing a switchover. You can reenable these features after downgrading or performing the switchover. For more information, see CSCvy19014.

     Non-disruptive downgrading from Cisco MDS NX-OS Release 8.5(1) to 8.4(x) is not supported. For more information, see CSCwd18183.

     If you are downgrading from Cisco MDS NX-OS Release 9.2(1) or later releases to a release prior to Cisco MDS NX-OS Release 9.2(1), ensure that you use the clear logging onboard txwait command after downgrading. 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.
