PowerStore Pre-Upgrade Health Check (PUHC) Remote System Data Connection State

The PowerStore pre-upgrade health check (PUHC) may fail if it detects the data connection to a remote system is in a Partial_Node_Connection_Loss state with the following error: "Remote system data connection state is Partial_Node_Connection_Loss, which will cause NDU failure during upgrade to 4.4.x. KB#000472474. Please contact your service provider. (off_release_data_connection_state_check)". 

This may be detected when running the PUHC.

Impact

During an NDU (Non-Disruptive Upgrade) to 4.4.x from any pre-4.4 releases, if the remote system data connection state is set to Partial_Node_Connection_Loss, the upgrade fails during the post-upgrade database (DB) migration phase

Please check connectivity between the PowerStore appliance and its replication partner/s.
