New Features in Cisco MDS SAN-OS Release 3.3(4)
Downgrading the SSI Image on Your SSM
Use the following guidelines when downgrading your SSI image on your SSM.
• On a system with at least one SSM installed, the install all command might fail on an SSM when
you downgrade from Cisco SAN-OS Release 3.3(4) to any SAN-OS 2.x release earlier than SAN-OS
Release 2.1(2e). Power down the SSM and perform the downgrade. Bring up the SSM with the new
bootvar set to the 2.x SSI image.
• Downgrade the SSI boot images on the SSMs on the switch to a release version supported by your
Cisco SAN-OS release. Refer to the Cisco MDS NX-OS Release Compatibility Matrix for Storage
Service Interface Images.
• SSM intelligent services traffic switching on SSM ports is disrupted on upgrades or downgrades.
• Fibre Channel switching traffic on SSM ports is not disrupted under the following conditions:
–
All SSM applications are disabled. Use the show ssm provisioning command to determine if
any applications are provisioned on the SSM. Use the no ssm enable feature configuration
mode command to disable these features.
–
The EPLD version on the SSM is at 0x07 or higher. Use the show version module slot epld
command to determine your EPLD version. Refer to the Cisco MDS 9000 Family Release Notes
for Cisco MDS 9000 EPLD Images to upgrade your EPLD image.
–
Refer to the Cisco Data Center Interoperability Support Matrix and the “Managing Modules”
chapter in the Cisco MDS 9000 Family CLI Configuration Guide, Release 3.x, for information
on downgrading your SSM.
Downgrading an MDS 9222i Switch
If you are running MDS NX-OS 4.1(1x) on an MDS 9222i switch and you need to downgrade to a
SAN-OS 3.3(x) release, you can downgrade to Release 3.3(2), 3.3(1c), or 3.3(1a), but you cannot
downgrade to 3.3(4). A nondisruptive downgrade from NX-OS 4.1(1x) to SAN-OS 3.3(4) is not
supported on the MDS 9222i switch. This restriction does not apply to other platforms.
Before downgrading, disable all features not supported by the downgrade release. Use the show
incompatibility system downgrade-image CLI command to determine what features you need to
disable.
Following the downgrade, you will need to enable features with the feature-name enable command, such
as the iscsi enable command. In NX-OS 4.1(x) releases, features are enabled with the feature
feature-name command, such as the feature iscsi command.
New Features in Cisco MDS SAN-OS Release 3.3(4)
This section briefly describes the new features introduced in this release. For detailed information about
the features listed, refer to the Cisco MDS 9000 Family CLI Configuration Guide, Release 3.x, the Cisco
MDS 9000 Family Fabric Manager Configuration Guide, and the Cisco MDS 9000 Family Storage
Media Encryption Configuration Guide. For information about new CLI commands associated with
these features, refer to the Cisco MDS 9000 Family Command Reference. The “New and Changed
Information” section in each of these books provides a detailed list of all new features and includes links
to the feature description or new command.
