Software Download Process
Downloading Software
The Cisco MDS NX-OS software is designed for mission-critical high availability environments. To
realize the benefits of nondisruptive upgrades on the Cisco MDS 9500 Directors, we highly recommend
that you install dual supervisor modules.
To download the latest Cisco MDS NX-OS software, access the Software Center at this URL:
http://www.cisco.com/public/sw-center
See the following sections in this release note for details on how you can nondisruptively upgrade your
Cisco MDS 9000 switch. Issuing the install all command from the CLI, or using Cisco DCNM for SAN
to perform the downgrade, enables the compatibility check. The check indicates if the upgrade can
happen nondisruptively or disruptively depending on the current configuration of your switch and the
reason.
Compatibility check is done:
Module bootable Impact Install-type Reason
------ -------- -------------- ------------ ------
1 yes non-disruptive rolling
2 yes disruptive rolling Hitless upgrade is not supported
3 yes disruptive rolling Hitless upgrade is not supported
4 yes non-disruptive rolling
5 yes non-disruptive reset
6 yes non-disruptive reset
At a minimum, you need to disable the default device alias distribution feature using the no device-alias
distribute command in global configuration mode. The show incompatibility system bootflash:system
image filename command determines which additional features need to be disabled.

Upgrading Your Cisco MDS NX-OS Software Image
Upgrading Guidelines Specific to NX-OS Release 5.2(1)
Follow these guidelines when upgrading to Cisco MDS NX-OS Release 5.2(1):
•Upgrade to NX-OS Release 5.2(1) before you install any Generation 4 module in an MDS 9500
Series switch. Generation 4 modules include the FCoE module and the 32-port and 48-port 8-Gbps
Advanced Fibre Channel modules. (See the “New Hardware” section on page 22 for a list of
Generation 4 hardware.) NX-OS Release 5.2(1) is needed for the switch to recognize the new
hardware.
•Perform a full switch reload on an MDS 9509 or MDS 9506 switch after you install NX-OS Release
5.2(1) and install any Generation 4 module, including the FCoE module. The switch reload is
required for the new hardware to come up. Once you perform the switch reload, the fabric mode
changes to support the Generation 4 hardware. Because of the changed fabric mode, you cannot
subsequently perform a nondisruptive software downgrade from NX-OS Release 5.2(1). For
additional information, see the “Downgrading Guidelines Specific to NX-OS Release 5.2(1)”
section on page 18
•Ensure that you have a Supervisor-2A module (DS-X9530-SF2A-K9) installed in a MDS 9500
Series switch if you plan to use the Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet
(FCoE) (DS-X9708-K9).
•We recommend that you delete any SPAN configuration, Fibre Channel tunnel, or tunnel-ID map
configuration from your switch before you start the upgrade to NX-OS Release 5.2(1). You can save
the SPAN destination and SPAN target configuration and then reconfigure the SPAN session
following the upgrade. All SPAN destination and SPAN target ports are reinitialized after the
upgrade. To gather information about SPAN sessions and delete them, use the following commands
in this order:
– show incompatibility systems bootflash:image_name to display any incompatible
configurations
– show span session to check the current configuration for a SPAN session
– no span session session-number to delete a SPAN session
– show running-config | include fc-tunnel to check the current Fibre Channel tunnel
configuration
– no interface fc-tunnel yto delete a Fibre Channel tunnel on the switch that is the source for the
Fibre Channel tunnel
– show interface brief | include SD to check the current configuration for a SPAN destination
port configuration
– show interface brief | include ST to check the current configuration for a SPAN target port
configuration
– no fc-tunnel tunnel-map zinterface x/y to remove an Fibre Channel tunnel map
– no switchport mode sd to negate the SPAN destination port mode for the SPAN destination port
– no switchport mode st to negate the SPAN target port mode for the SPAN target port
•If you are using IVR non-NAT mode, migrate to IVR-NAT mode before you upgrade to NX-OS
Release 5.2(1). IVR non-NAT mode is deprecated in NX-OS Release 5.2(1).
Note In dual SAN fabrics, IVR traffic can use one fabric while the other fabric is migrating. Only
IVR traffic is disrupted during the migration. Regular traffic within the VSAN is not
disrupted during the migration.

Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(1)
OL-25090-01
Upgrading Your Cisco MDS NX-OS Software Image
To migrate to IVR-NAT mode, follow these steps:
1. Stop or divert all applications on servers that depend on IVR.
– If CFS distribution is not enabled for IVR, then perform steps 2 through 4 on all switches where
IVR is enabled.
– If CFS distribution is enabled for IVR, then enter the ivr commit command following step 2,
step 3, and step 4 to distribute the changes to other switches.
2. Deactivate the IVR zone set by entering the no ivr zoneset activate command.
3. Enable IVR NAT by entering the ivr nat command.
4. Activate the IVR zone set by entering the ivr zoneset activate command.
5. Start or re-establish all application that were stopped in step 1.
The network can now run in IVR-NAT mode.
General Upgrading Guidelines
Follow these general guidelines before performing a software upgrade:
•Review the nondisruptive upgrade path to release 5.2(1) in Table 10.
•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 10 for the nondisruptive upgrade path for all NX-OS and SAN-OS
releases.
– Gigabit Ethernet Ports:Traffic on Gigabit Ethernet ports is disrupted during an upgrade or
downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MSM-18/4 module
and the MDS 9222i switch. 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.
– FICON: If you have FICON enabled, the upgrade path is different. See the “FICON Supported
Releases and Upgrade Paths” section on page 17.
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 10 to determine your nondisruptive upgrade path to Cisco MDS NX-OS Release 5.2(1), find
the image release number you are currently using in the Current column of the table, and use the path
recommended.
Note The software upgrade information in Table 10 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
Use Table 12 to determine the nondisruptive upgrade path for FICON-certified releases. Find the image
release number you are currently using in the Current Release with FICON Enabled column of the table
and follow the recommended path.
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:
•Downgrading Guidelines Specific to NX-OS Release 5.2(1), page 18
•General Downgrading Guidelines, page 19
Downgrading Guidelines Specific to NX-OS Release 5.2(1)
The following guideline applies to a downgrade from Cisco MDS NX-OS Release 5.2(1):
•You cannot nondisruptively downgrade from NX-OS Release 5.2(1) to NX-OS Release 5.0(x) if you
installed NX-OS Release 5.2(1) on an MDS 9509 or MDS 9506 switch and you installed a
Generation 4 module in the switch and performed a full switch reload. The reason for this restriction
is the change in fabric mode that occurs following the switch reload with the Generation 4 hardware
installed. The downgrade will be disruptive, even if you remove the Generation 4 module prior to
starting the downgrade.
If you do not install Generation 4 hardware or perform a full switch reload following the installation
of NX-OS Release 5.2(1) on an MDS 9509 or MDS 9506 switch, then you can nondisruptively
downgrade to NX-OS Release 5.0(x).
•We recommend that you delete any SPAN configuration, Fibre Channel tunnel, or tunnel-ID map
configuration from your switch before you downgrade from NX-OS Release 5.2(1) to a lower
version. If any SPAN session, SPAN destination, SPAN target, or Fibre Channel tunnel interface is
configured, the installer should detect it and prompt you to delete these configurations.
To gather information about SPAN sessions and delete them, use the following commands in this
order:
– show incompatibility systems bootflash:image_name to display any incompatible
configurations
– show span session to check the current configuration for a SPAN session
– no span session session-number to delete a SPAN session

General Downgrading Guidelines
Follow these general guidelines before you perform a a software downgrade:
•Issue the system no acl-adjacency-sharing execute command to disable ACL adjacency usage on
Generation 2 and Generation 1 modules. 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:
– FCoE: Fibre Channel over Ethernet requires Cisco NX-OS Release 5.2(1). A downgrade from
Release 5.2(1) disrupts and stops all FCoE traffic.
– 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 Gigabit Ethernet ports is disrupted during a downgrade.
This includes IPS modules and the Gigabit Ethernet ports on the MSM-18/4 module, and the
MDS 9222i switch. 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.
– FICON: If you have FICON enabled, the downgrade path is different. See the “FICON
Downgrade Paths” section on page 20.
Use Table 13 to determine the nondisruptive downgrade path from Cisco NX-OS Release 5.2(1). Find
the NX-OS or SAN-OS image you want to downgrade to in the To SAN-OS Release column of the table
and use the path recommended.
Note The software downgrade information in Table 13 applies only to Fibre Channel switching traffic.
Downgrading system software disrupts IP and intelligent services traffic.

technology that enables ports to be configured as either 1-, 2-, 4-, or 8-Gbps, or 10-Gbps Fibre
Channel interfaces.
Cisco MDS 9000 8-Gbps Advanced Fibre Channel switching modules support Arbitrated Local
Switching to locally switch traffic at line rate 8-Gbps in a fair manner across all ports on the module
through central arbitration.
•Storage Media Encryption for Disk
The Storage Media Encryption (SME) solution, which currently protects data at rest on
heterogeneous tape drives and virtual tape libraries (VTLs), has been enhanced to encrypt data on
disk arrays in a SAN environment using secure IEEE-standard Advanced Encryption Standard
(AES) algorithms.
SME Disk requires the Storage Media Encryption Package license.
See the Cisco MDS 9000 Family Storage Media Encryption Configuration Guide for more
information on configuring and deploying SME Disk.
