Initial Release |
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.
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.
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(1).
For more information on EPLD bundles, see the Cisco MDS 9000 Series EPLD Release Notes, Release 9.4(1).
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.
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(1) 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.
Upgrading Cisco MDS NX-OS Software Image
This section lists the guidelines that are recommended for upgrading Cisco MDS NX-OS software images 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.
This section lists the general guidelines for performing a software upgrade:
● Before the software upgrade, collect the output of the show tech-support details command. Save the output in a secure location.
● Cisco MDS 9700 Series Director switches support dual redundant supervisor modules. To allow a nondisruptive upgrade on these platforms, ensure that both the modules are installed and functional. The show module command must display one with the status “active” and the other as “ha-standby”.
● Use the show install all impact <target-system-image> command to determine if the upgrade will be nondisruptive.
● Some features are impacted by 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.
◦ IPStorage Ports: Traffic on IPStorage ports on Cisco MDS 9220i, 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 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 an upgrade.
Note: In addition to these guidelines, review the information in Limitations and Restrictions before a software upgrade to determine if a feature may behave differently after the upgrade.
● The same release of the target 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 releases, ensure that you perform a switchover before upgrading. For more information, see CSCvt87216.
● Starting with Release 9.2(1), the size of the TxWait log file has increased. After the upgrade is complete, ensure that you use clear logging onboard txwait to clear the logging area. 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.

Downgrading Cisco MDS NX-OS Software Image
This section lists the guidelines that are recommended for downgrading Cisco MDS NX-OS software images and includes the following topics:
● General Downgrading Guidelines
● Open Systems Nondisruptive Downgrade Paths
General Downgrading Guidelines
This section lists the general guidelines for performing a software downgrade:
● Before the software downgrade, collect the output of the show tech-support details command. Save the output in a secure location.
● Cisco MDS 9700 Series Director switches support dual redundant supervisor modules. To allow a nondisruptive downgrade on these platforms, ensure that both the supervisor modules are installed and functional. The show module command must display one with status as “active” and the other as “ha-standby”.
● Use the show install all impact <downgrade-system-image> command to determine if the downgrade will be nondisruptive.
● From Cisco MDS NX-OS Release 9.4(1), ensure that the LLDP feature is disabled before you perform the downgrade to target release.
● 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.
● 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.
● 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.
