ONTAP-312808:FPolicy永続ストアを有効にした状態で9.14.1xから9.15.1xへのアップグレードを実行するとONTAPがクラッシュすることがある
問題
The system must be running Ontap 9.14.1x and Fpolicy Persistent store must be enabled. When trying a non-disruptive upgrade to 9.15.1x or higher version, with IO running, system may crash post upgrade. This issue is cause due to discrepancy in Persistent-store file name format between the two versions, leading to parsing issue post upgrade which my cause system crash.
