EMC has released another OE for EMC Unity family both hybrid and all flash models. The new OE has no new feature but this OE image has important fix.
The array may experience a single unplanned storage processor reboot without creating a dump file or any other noticeable impact due to Unity’s high availability features. Refer to Dell EMC Knowledge base article 531208 for more information.
I recommend, plan and upgrade to this OE even you don’t use
Unity’s high availability features now.
