First Published: October, 2018
This document describes the caveats and limitations for switches in the Cisco MDS 9000 Series. Use this document in conjunction with documents listed in the “Obtaining Documentation and Submitting a Service Request” section.
Release notes are sometimes updated with new information on restrictions and caveats. Refer to the following website for the most recent version of the Cisco MDS 9000 Series Release Notes.
This document includes the following:
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 MDS NX-OS release numbering to indicate when significant features or hardware support are added to the code. This allows older trains to provide stability and newer trains to focus new features and hardware.
Note Before upgrading Cisco MDS 9396S switch in Cisco N-Port Virtualizer (NPV) mode from Cisco MDS NX-OS Release 6.2(21) or earlier to Cisco MDS NX-OS Release 6.2(25), refer to the CSCvd74861, CSCvd74840, CSCvh97251, and CSCvi10304 defects for the risks, limitations, and workarounds.

::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(25). 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 11 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 11 to determine your nondisruptive upgrade path to Cisco MDS NX-OS Release 6.2(25). 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 11 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 12 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 12 to determine the nondisruptive downgrade path from Cisco NX-OS Release 6.2(25). 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 12 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 High Voltage DC (HVDC) PSU is installed.

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.
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.
