Juniper QFX3000-G QFabric, Deployment Manual, Page: 499 / 652

NOTE: If you receive an error message after issuing the request system
software add package-name component all reboot command that says
that the configuration file cannot be loaded as is, you will need to enter
configuration mode, make any necessary changes to the configuration
file, and then commit the changes.
NOTE: The default value for a QFabric system software upgrade is
validate
.
The validation step adds up to 10 minutes to the overall software upgrade.
If the validation fails, the upgrade does not proceed and the QFabric system
automatically issues the
request system software rollback command to
restore the current software image. If you upgrade more than one
component (for example, by issuing the
component all option), validation
failure on one device stops the upgrade process for the other devices. If
you do not want to validate the software package against the current
configuration, issue the
no-validate
option.
2.
After the reboot has finished, verify that the new version of software has been properly
installed by issuing the
show version component all command.
