MD3820i PVCF_EXCEPTION when applying changes in MDCU?

Hello dell community,

when configuring an md3820i unit through mdcu I experience an "unknown error (pvcf_exception)" when hitting the "apply changes" button in the summary screen of the configuration wizard. Searching around for a solution was not very conclusive as I saw similar threads without solution posted. I was unable to configure the unit eventually.

Anyone else having an idea what's causing this error and if this can be resolved?
