Issue

When upgrading ONTAP from 9.3 to 9.4, 9.5 or 9.6, a node fails during giveback with the following error and panic:

Wed Apr 15 19:18:15 CST [ToasterA: fmmbx_instanceWorker: fmmb.add.problem:error]: Error attempting to add disk 6002538A:76118940:500A0981:00000002:00000000:00000000:00000000:00000000:00000000:00000000 as a Local HA mailbox disk.

Prior to the upgrade, ONTAP reports failures for the same mailbox disks within EMS similar to the following:
