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 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 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/home.
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 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 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(1) 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 the Cisco DCNM Release Notes.
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 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.
◦ If you are upgrading from a release prior to Cisco MDS NX-OS Release 9.2(1), 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 the 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), ensure that you disable the Fabric Performance Monitor (FPM) feature using the no feature fpm command before upgrading.
◦ We recommend that if all of the following conditions are true that the Cisco MDS 48-Port 64-Gbps Fibre Channel Switching Module (DS-X9748-3072K9) NOT be inserted in the chassis:
o Cisco MDS 9706, MDS 9710, or MDS 9718
o Cisco MDS NX-OS Release 9.2(1)
o Non-default FCoE FCMAP is configured. This can be checked by issuing the show fcoe | i FC-MAP command. The default value of FCMAP is 0x0e:fc:00.
Also, for the switches running Release 9.2(1) and equipped with Cisco MDS 48-Port 64-Gbps Fibre Channel Switching Module (DS-X9748-3072K9), the FCMAP should NOT be changed to non-default value. However, after the switch has been upgraded to Release 9.2(2) or later, the FCoE FCMAP can be configured to a non-default value. For more information, see CSCwa34016.
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.

Downgrading Cisco MDS NX-OS Software Image
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.
● 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 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.
◦ 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.

Cisco MDS 48 Port 64 Gbps Fibre Channel Switching Module
The Cisco MDS 48-Port 64-Gbps Fibre Channel Switching Module (DS-X9748-3072K9) is supported on Cisco MDS 9700 Series Multilayer Directors. This module delivers predictable performance, scalability, and innovative features to support private and virtualized data centers.
For more information about this module, see Product Overview chapter in Cisco MDS 9700 Series Hardware Installation Guide.
Secure Syslog
The ability to log syslogs securely to a remote syslog server was added. This feature allows you to securely log system messages to a configured remote logging server using TLS. The trustpoint client-identity option was added to the logging server command.
For more information, see Cisco MDS 9000 Series System Management Configuration Guide, Release 9.x.
VMID Analytics
The allocation of the VMIS field in the CS_CTL FC header field has changed. The range 1 - 15 is reserved for ER_RDY use and 16 - 255 for VMID use.
The vmis range range vsan id command was modified.
For more information, see Cisco MDS 9000 Series Fabric Configuration Guide, Release 9.x.
Standby Supervisor mgmt0 Status
The ability to check the standby supervisor mgmt0 interface was added. A warning message and syslog are generated to alert the user if the standby supervisor Ethernet management port is disconnected or down before performing an In-Service Software Upgrade (ISSU) or system switchover.
The show interface mgmt number standby command was also introduced to display the status of the standby supervisor mgmt0 interface.
Upgrading (ISSU) or downgrading (ISSD) from Cisco MDS NX-OS Release 9.2(1) or later releases will also check the status of the standby supervisor mgmt0 interface. If the interface is not up, a message will be printed in the same group of messages that indicate if the upgrade or downgrade will be hitless or not.
The system switchover command has been enhanced to not allow a switchover to the standby supervisor and displays a message when the standby supervisor mgmt0 interface is not up. To bypass this check, the bypass-standby-mgmt0 parameter was added to the system switchover command.
For more information, see Cisco MDS 9000 Series High Availability Configuration Guide, Release 9.x.
Secure Remote System Message Logging
The ability to log syslogs securely to a remote syslog server was added. This feature allows you to securely log system messages to a configured remote logging server using TLS. The secure and trustpoint client-identity options were added to the logging server command.
For more information, see Cisco MDS 9000 Series System Management Configuration Guide, Release 9.x.
MIB Support for Standby Supervisor mgmt0 Status for Device Manager
The CISCO-ENTITY-DISPLAY-MIB is updated to add support for standby supervisor mgmt0 status. For downloading MIBs, see ftp://ftp.cisco.com/pub/mibs/.
On-board Failure Logging
The log size for TXWait counter in OBFL was changed from 512 KB to 8 MB. After upgrading or downgrading from Cisco MDS NX-OS Release 9.2(1) or later releases, the TxWait OBFL will need to be cleared manually via the clear logging onboard txwait command.
For more information, see Cisco MDS 9000 Series Interfaces Configuration Guide, Release 9.x.
Fabric Notifications
The Fabric Notification — FPIN and Congestion Signal feature is out of the preview (beta) status and can be used in the production environment.
For more information, see Congestion Management chapter in Cisco MDS 9000 Series Interfaces Configuration Guide, Release 9.x.
Data Mobility Manager
From Cisco MDS NX-OS Release 8.1(1), the Cisco MDS Data Mobility Manager 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 bring up these modules. In addition, you cannot configure these features after you bring up these modules.
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.
SAN Extension Tuner
San Extension Tuner (SET) is not supported on Cisco MDS 9220i switches in Cisco MDS NX-OS Release 9.2(1).
