Impact
If an NDU were to run with this underlying issue, the NDU may fail and require manual intervention.

Cause

In rare cases, different appliances may host CP and databases following issues encountered during a prior NDU that include system restarts during critical upgrade phases. These restarts may result in the loss of necessary state data, preventing the system from generating the required command to manage eligibility.

Resolution

This issue is resolved starting with PowerStoreOS version 4.0. A workaround must be applied to an affected system on versions prior to PowerStoreOS 4.0 before starting an NDU. Contact Dell Technical Support and refer to this article for assistance remediating this issue.
