Troubleshooting Cisco SAN-OS Software Upgrades and
Downgrades
This section discusses possible causes and solutions for a software installation upgrade or downgrade
failure. It includes the following symptoms:
• Software Installation Reports an Incompatibility, page 2-7
• Software Installation Ends with Error, page 2-9
Software Installation Reports an Incompatibility
Symptom The software installation reports an incompatibility.
Diagnosing Compatibility Issues
To view the results of a dynamic compatibility check, use the show incompatibility system
bootflash:filename CLI command.
Use the show incompatibility CLI command for diagnosis when the install all CLI command warns of
compatibility issues.
During an attempted upgrade, the install all CLI command may return the following warning:
Warning: The startup config contains commands not supported by the system image; as a
result, some resources might become unavailable after an install.

reports an incompatibility.
The running image may have a feature
enabled that is not compatible with the
proposed new image.
Review the incompatibility issues displayed by
either the Fabric Manager Software Install Wizard
or the install all CLI command. Correct any
problems and retry the installation. See the
“Diagnosing Compatibility Issues” section on
page 2-7.
Verify which features are enabled on your switch
and disable any features that may not be
compatible with your new image. Refer to the
appropriate release notes for both images.
