Upgrading Your Cisco MDS NX-OS Software Image
This section lists the guidelines recommended for upgrading your Cisco MDS NX-OS software image and includes the following topics:
Note Before you begin the upgrade process, review the list of chassis and modules that Cisco MDS NX-OS Release 6.2(11d) supports. See the “MDS 9000 Chassis and Module Support” section.
For detailed instructions for performing a software upgrade using Cisco DCNM, see the Cisco DCNM Release Notes, Release 6.2, which is available from the following website:
Follow these general guidelines before performing a software upgrade:
Review the nondisruptive upgrade path to Release 6.2(11d) in Table 14.
Install and configure dual supervisor modules before the upgrade.
Issue the show install all impact upgrade-image CLI command to determine if your upgrade will be nondisruptive.
Be aware that some features impact whether an upgrade is disruptive or nondisruptive:
– Fibre Channel Ports : Fibre Channel ports can be nondisruptively upgraded without affecting traffic on the ports. See Table 14 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 downgrade 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.
Note Upgrading from Cisco MDS NX-OS Releases 6.2(9b) or 6.2(9c) to Cisco MDS NX-OS Releases 6.2(11), 6.2(11b), 6.2(11c), or 6.2 (11d) is not supported due to the introduction of a new feature to support longer role names (a maximum of 64 characters) in the Cisco MDS NX-OS Releases 6.2(9b) and 6.2(9c).
Nondisruptive Upgrade Paths
Use Table 14 to determine your nondisruptive upgrade path to Cisco MDS NX-OS Release 6.2(11d). 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 14 applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and intelligent services traffic.

Downgrading Your Cisco MDS SAN-OS Software Image
This section lists the guidelines recommended for downgrading your Cisco MDS SAN-OS software image and includes the following topics:
Follow these general guidelines before you perform a software downgrade:
Issue the system no acl-adjacency-sharing EXEC command to disable ACL adjacency usage on Generation 2 modules (Generation 2 modules or switches can have one or more ports in port groups that share common resources such as bandwidth and buffer credits.). If this command fails, reduce the number of zones, IVR zones, TE ports, or a combination of these in the system and issue the command again.
Disable all features not supported by the downgrade release. Use the show incompatibility system downgrade-image command to determine what you need to disable.
Use the show install all impact downgrade-image command to determine if your downgrade will be nondisruptive.
Be aware that some features impact whether a downgrade is disruptive or nondisruptive:
– Fibre Channel Ports : Fibre Channel ports can be nondisruptively downgraded without affecting traffic on the ports. See Table 17 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 17 to determine the nondisruptive downgrade path from Cisco NX-OS Release 6.2(11d). Find the NX-OS or SAN-OS image that you want to downgrade to in the To 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 17 applies only to Fibre Channel switching traffic. Downgrading system software disrupts IP and intelligent services traffic.
Note Downgrading from Cisco MDS NX-OS Releases 6.2(11), 6.2(11b), 6.2(11c), or 6.2(11d) to Cisco MDS NX-OS Releases 6.2(9b) or 6.2(9c) is not supported due to the introduction of a new feature to support longer role names (a maximum of 64 characters) in Cisco MDS NX-OS Releases 6.2(9b) and 6.2(9c).

New Software Features in Cisco MDS NX-OS Release 6.2(11c)
This section briefly describes the new software features introduced in Cisco MDS NX-OS Release 6.2(11c).
Enabling FEC with TTS
For detailed information about this feature, see the following document:
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, and the Cisco MDS 8-Gb Fabric Switch for HP c-Class Blade System.
Note A license is not required to use 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:
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.
SAN Extension over IP Package
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 fact sheet for more information.
Mainframe Package
The Cisco MDS 9000 Mainframe package uses the FICON protocol and allows control unit port management for in-band management from IBM System z processors. FICON VSAN support is provided to help ensure true hardware-based separation of FICON and open systems. Switch cascading, fabric binding, and intermixing are also included in this package. Refer to the Cisco MDS 9000 Mainframe package fact sheet for more information.
Data Mobility Manager Package
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 package fact sheet for more information. The Data Mobility Manager package is for use only with Cisco MDS 9000 Series switches.
On-Demand Port Activation License
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, and the Cisco MDS 8-Gb Fabric Switch for HP c-Class Blade System. As needed, customers can expand switch connectivity by licensing additional ports.
I/O Accelerator Package
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.
XRC Acceleration License
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.
Deprecated and Changed Features
Zoning Features
LUN zoning, read-only zones, and broadcast zones are no longer supported. These features affect the following hardware:
You cannot bring up these modules if these features are already configured. You should completely remove all configurations that include these features before you attempt to bring up these modules. In addition, you cannot configure these features after you bring up these modules.
In addition, the following software features are not supported or are changed in Cisco MDS NX-OS Release 6.2(9):
Fibre Channel Security Protocol (FC-SP) is currently not supported on Cisco MDS 9250i Multiservice Fabric Switch.
Local switching is not supported on the Cisco MDS 9700 Series Director, but continues to be supported on the Cisco MDS 9500 Series.
Online Health Management System (OHMS)—The Generic Online Diagnostics (GOLD) system provides diagnostics for the Cisco MDS 9700 Series Director instead of the OHMS. In Cisco NX-OS Release 6.2, the GOLD system does not provide any support for automation of corrective actions, such as rebooting modules based on error thresholds.
Note OHMS is supported on Cisco MDS 9500 Series directors, Cisco MDS 9250i Multiservice Fabric Switch, Cisco MDS 9148S Multilayer Fabric Switch, and Cisco MDS 9148 Multilayer Fabric Switch.
Cisco NX-OS Release 6.2 does not support the following hardware:
Cisco MDS 9134 Fabric Switch
Cisco MDS 9124 Fabric Switch
Cisco MDS 4-Gbps Fabric Switch for HP c-Class BladeSystem
Cisco MDS 4-Gbps Fabric Switch for IBM BladeCenter
