Impact

Unable to upgrade the Switch OS using PFxM.

Cause

This is a recognized software code problem. When the Switch IP address is located on an "OOB" network rather than the PFMP Management subnet, PFxM encounters a failure in transferring the files for the upgrade.

This issue is mentioned in the PowerFlex 4.5 Release notes for issue VXFM-35909.

Resolution

Manually upgrade the Switch OS.
