If the install all command is ended, be sure to verify the state of the switch at every stage and reissue

the command after 10 seconds. If you reissue theinstall all command within the 10-second span, the
command is rejected with an error message indicating that an installation is currently in progress.
All configurations are disallowed while the install all command is in progress. However, configurations

After issuing the command, if any step in the sequence fails, the command 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 the install all command is issued on the standby supervisor module.
If the install all command does not reference the default bootflash: in a dual supervisor module
configuration.
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 show install all impact command in the compatibility check section
of the output (under the Bootable column).
