Guidelines and Limitations for SMUs
SMUs have the following guidelines and limitations:
•
Some packages require the activation or deactivation of other packages. If the SMUs have dependencies
on each other, you cannot activate them without first activating the previous ones.
•
The package being activated must be compatible with the current active software set.
•
You cannot activate multiple SMUs in one command.
•
Activation is performed only after the package compatibility checks have been passed. If a conflict is
found, an error message displays.
•
While a software package is being activated, other requests are not allowed to run on any of the impacted
nodes. Package activation is completed when a message similar to this one appears:
Install operation 1 completed successfully at Thu Jan 9 01:19:24 2014
•
Each CLI install request is assigned a request ID, which can be used later to review the events.
•
If you perform a software maintenance upgrade and later upgrade your device to a new Cisco Nexus
3500 software release, the new image will overwrite both the previous Cisco Nexus 3500 release and
the SMU package file.

Preparing for Package Installation
You should use several show commands to gather information in preparation for the SMU package installation.
Before You Begin
Determine if a software change is required.
Verify that the new package is supported on your system. Some software packages require that other packages
or package versions be activated, and some packages support only specific line cards.
Review the release notes for important information related to that release and to help determine the package
compatibility with your device configuration.
Verify that the system is stable and prepared for the software changes.
