Description

This command starts a non-disruptive upgrade and can skip certain checks to push a non-disruptive upgrade when the ndu

pre-checks command fails. The pre-checks executed by the ndu pre-check command verify that the upgrade from the

current software to the new software is supported, the configuration supports NDU, and the system state is ready (clusters and

volumes are healthy).

You must resolve all issues disclosed by the ndu pre-check command before running the ndu start command.

Skip options enable ndu start to skip one or more NDU pre-checks. Skip options should be used only after fully understanding

the problem reported by the pre-check to minimize the risk of data unavailability.

NOTE: Skip options may be combined to skip more than one pre-check. Multiple skip options must be separated by a space.

NOTE: It is recommended that you upgrade metro node using the upgrade procedure found in the SolVe Desktop. This

procedure also details when the ndu start command should be used with skip options and how to select and use those

skip options.
