The Cisco MDS 9000 Series of Multilayer Directors and Fabric Switches provides industry-leading availability, scalability, security, and management, allowing you to deploy high-performance storage-area networks with lowest total cost of ownership. Layering a rich set of intelligent features onto a high-performance, protocol agnostic switch fabric. The Cisco MDS 9000 Series addresses the stringent requirements of large data center storage environments: uncompromising high availability, security, scalability, ease of management, and seamless integration of new technologies.
Cisco MDS 9000 NX-OS software powers the award-winning Cisco MDS 9000 Series Multilayer Switches. It is designed to create a strategic SAN platform with superior reliability, performance, scalability, and features. Formerly known as Cisco SAN-OS, Cisco MDS 9000 NX-OS software is fully interoperable with earlier Cisco SAN-OS versions and enhances hardware platform and module support.
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 6.2(29) 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.

::10.1.2.255/0
If a switch is found to be affected, there are specific steps that must be taken after upgrading to Cisco MDS NX-OS Release 6.2(29). For information on these specific steps, see the Resolution Summary section in CSCvg05230.– Fibre Channel Ports : Fibre Channel ports can be nondisruptively upgraded without affecting traffic on the ports. See Table 12 for the nondisruptive upgrade path for all NX-OS and SAN-OS releases.
– Gigabit Ethernet Ports : Traffic on GigabitEthernet/IPStorage ports is disrupted during an upgrade or downgrade. This includes the Gigabit Ethernet ports on the MSM-18/4 module, the MDS 9222i switch, the MDS 9000 16-Port Storage Services Node (SSN-16), and the IPStorage ports in MDS 9250i. Those nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the upgrade is in progress.
Note In addition to these guidelines, you may want to review the information in the “Limitations and Restrictions” section prior to a software upgrade to determine if a feature may possibly behave differently following the upgrade.
Use Table 12 to determine your nondisruptive upgrade paths to Cisco MDS NX-OS Release 6.2(29). Find the image release number you are currently using in the “Current Release” column of the table and follow the steps in the order specified to perform the upgrade.
Note The software upgrade information in Table 12 applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and intelligent services traffic.
This section lists the guidelines recommended for downgrading your Cisco MDS NX-OS software image and includes the following topics:
Follow these general guidelines before you perform a software downgrade:
– Fibre Channel Ports : Fibre Channel ports can be nondisruptively downgraded without affecting traffic on the ports. See Table 13 for the nondisruptive downgrade path for all SAN-OS releases.
– Gigabit Ethernet Ports : Traffic on GigabitEthernet/IPStorage ports is disrupted during a downgrade. This includes the Gigabit Ethernet ports on the MSM-18/4 module, the MDS 9222i switch, the MDS 9000 16-Port Storage Services Node (SSN-16), and the IPStorage ports in MDS 9250i. Those nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the downgrade is in progress.
Use Table 13 to determine the nondisruptive downgrade path from Cisco NX-OS Release 6.2(29). Find the NX-OS or SAN-OS image that you want to downgrade to in the To NX-OS or SAN-OS Release column of the table and follow the steps in the order specified to perform the downgrade.
Note The software downgrade information in Table 13 applies only to Fibre Channel switching traffic. Downgrading system software disrupts IP and intelligent services traffic.
Refer to the “General Downgrading Guidelines” section.
Downgrade to releases that do not support the High Voltage DC (HVDC) PSU will not work or the downgrade will be prevented if the HVDC PSU is installed.
Use Table 13 to determine your nondisruptive downgrade paths from Cisco MDS NX-OS Release 6.2(29) to an earlier release. Find the image release number that you want to downgrade to in the “To MDS NX-OS or SAN-OS Release” column of the table and follow the steps in the order specified to perform the downgrade.
There are no new hardware features in Cisco MDS NX-OS Release 6.2(29).
This section lists the new software features introduced in Cisco MDS NX-OS Release 6.2(29).
This feature introduces a new command which enables dynamic addition of Organizationally Unique Identifiers (OUIs) to the system OUI database.
For detailed information, see the Cisco MDS 9000 Series NX-OS Fabric Configuration Guide and Cisco MDS 9000 Family Command Reference.
Most Cisco MDS 9000 Series software features are included in the standard package. However, some features are logically grouped into add-on packages that must be licensed separately, such as the Cisco MDS 9000 Enterprise package, SAN Extension over IP package, Mainframe package, and Data Mobility Manager package. On-demand ports activation licenses are also available for the Cisco MDS 9250i Multiservice Fabric Switch, Cisco MDS 9148 48-Port Multilayer Fabric Switch, Cisco MDS 9148S 48-Port Multilayer Fabric Switch, the Cisco MDS 8-Gb Fabric Switch for HP c-Class Blade System, and the Cisco MDS 9396S 96-Port Multilayer Fabric Switch.
Note A license is not required for the Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) module (DS-X9708-K9), and the Cisco MDS 48-Port 10- Gigabit Fibre Channel over Ethernet Module (DS-X9848-480K9).
Additional information about licensed Cisco NX-OS software packages is available at this URL:
http://www.cisco.com/c/en/us/products/storage-networking/mds-9000-software-licensing/datasheet-listing.html
The standard software package that is bundled, at no charge, with the Cisco MDS 9000 Series switches includes the base set of features that Cisco believes are required by most customers for building a SAN. The Cisco MDS 9000 Series also has a set of advanced features that are recommended for all enterprise SANs. These features are bundled together in the Cisco MDS 9000 Enterprise package. Refer to the Cisco MDS 9000 Enterprise Package Fact Sheet for more information.
The Cisco MDS 9000 SAN Extension over IP package allows the customer to use FCIP to extend SANs over wide distances on IP networks using the Cisco MDS 9000 Series IP storage services. Refer to the Cisco MDS 9000 SAN Extension Over IP Package for more information.
The Cisco MDS 9000 Data Mobility Manager package enables data migration between heterogeneous disk arrays without introducing a virtualization layer or rewiring or reconfiguring SANs. Cisco DMM allows concurrent migration between multiple LUNs of unequal size. Rate-adjusted migration, data verification, dual Fibre Channel fabric support, and management using Cisco DCNM for SAN provide a complete solution that greatly simplifies and eliminates most downtime associated with data migration. Refer to the Cisco MDS 9000 Data Mobility Manager License - Fact Sheet for more information. The Data Mobility Manager package is for use only with Cisco MDS 9000 Series switches.
On-demand ports allow customers to benefit from Cisco NX-OS Software features while initially purchasing only a small number of activated ports on the Cisco MDS 9250i Multiservice Fabric Switch, MDS 9148S 48-Port Multilayer Fabric Switch, MDS 9148 48-Port Multilayer Fabric Switch, the Cisco MDS 8-Gb Fabric Switch for HP c-Class Blade System, and the Cisco MDS 9396S Multilayer Fabric Switch. As needed, customers can expand switch connectivity by licensing additional ports.
The Cisco I/O Accelerator (IOA) package activates IOA on the Cisco MDS 9222i fabric switch, the Cisco MDS 9000 18/4 Multiservice Module (MSM-18/4), and on the SSN-16 module. The IOA package is licensed per service engine and is tied to the chassis. The number of licenses required is equal to the number of service engines on which the intelligent fabric application is used.The SSN-16 requires a separate license for each engine on which you want to run IOA. Each SSN-16 engine that you configure for IOA checks out a license from the pool managed at the chassis level. SSN-16 IOA licenses are available as single licenses.
The Cisco Extended Remote Copy (XRC) acceleration license activates FICON XRC acceleration on the Cisco MDS 9222i switch, the Cisco MDS 9250i switch, and the SSN-16 or MSM-18/4 in the Cisco MDS 9500 Series directors. One license per chassis is required. You must install the Mainframe Package and the SAN Extension over FCIP Package before you install the XRC acceleration license. The Mainframe Package enables the underlying FICON support, and the FCIP license or licenses enable the underlying FCIP support.
The Storage Media Encryption (SME) feature is not supported by Cisco from Cisco MDS NX-OS 6.2(29) onwards. Cisco MDS NX-OS 6.2(27) is the final release to support this feature. Remove all the SME related commands and disable the SME feature before upgrading to any release later than Cisco MDS NX-OS 6.2(27). The feature and commands are still functional in post Cisco MDS NX-OS 6.2(27) releases, but any issues encountered by the user in these releases will not be supported by Cisco.
The SME feature affects the following hardware types:
This section lists the limitations and restrictions. The following limitations are described:
The recommended DCNM version for Cisco MDS NX-OS Release 6.2(29) is Cisco DCNM, Release 10.x or later. For more information on the DCNM releases that are compatible with the MDS releases, see the Cisco DCNM Compatibility Matrix.
When trunking is enabled on the NPV ports of any MDS switch (released before the Cisco MDS 9396S Multilayer Fabric Switch) that runs on an MDS NX-OS release earlier than 6.2(13), and you have to connect an NPIV-enabled Cisco MDS 9396S Multilayer Fabric Switch, use only ports fc1/1 through fc1/63.
Note Trunking failure can occur in both non-portChannel (individual physical NP uplinks) and portChannel NP uplinks. To avoid trunking failure, ensure that you upgrade the NPV switch to Cisco MDS NX-OS Release 6.2(13) or above.
The copy bootflash:running-config.ascii startup-config command that was deprecated in an earlier Cisco NX-OS release is enabled from Cisco NX-OS Release 6.2(1).
From Cisco MDS NX-OS Release 6.2(9) onwards, the FC-SP feature is supported on Cisco MDS 9700 Series.
The install module module-number bios command is not supported on the Cisco MDS 9710 switch in Cisco NX-OS Release 6.2(1) and later releases. Use the install all command to upgrade the BIOS during a software upgrade.
The install module module-number bios command continues to be supported in Cisco NX-OS Release 6.2(1) on Cisco MDS 9500 Series switches.
