Caution If the installation is ended, be sure to verify the state of the switch at every stage and reissue the
command after 10 seconds. If you reissue the installation within the 10-second span, it is rejected with
an error message indicating that an installation is currently in progress.
All configurations are disallowed while the installation is in progress. However, configurations coming

through the CFS applications are allowed and may affect the upgrade procedure.

After a switchover process, you can see the progress from both the supervisor modules.
–
Before a switchover process, you can only see the progress from the active supervisor module.
–
The Software Install Wizard automatically checks the image integrity. This includes the running
kickstart and system images.
The Software Install Wizard performs a platform validity check to verify that a wrong image is not
used—for example, to check if an MDS 9500 Series image is used inadvertently to upgrade an MDS
9200 Series switch.
After issuing the installation, if any step in the sequence fails, the wizard completes the step in
progress and ends.
For example, if a switching module fails to be updated for any reason (for example, due to an
unstable fabric state), then the command sequence disruptively updates that module and ends. In
such cases, you can verify the problem on the affected switching module and upgrade the other
switching modules.
If the standby supervisor module bootflash: file system does not have sufficient space to accept the
updated image.
If the specified system and kickstart images are not compatible.
If the fabric or switch is configured while the upgrade is in progress.
If a module is removed while the upgrade is in progress.
If the switch has any power disruption while the upgrade is in progress.
If the entire path for the remote location is not specified accurately.
If images are incompatible after an upgrade. For example, a switching module image may be
incompatible with the system image, or a kickstart image may be incompatible with a system image.
This is also identified by the Software Install Wizard compatibility check.
