Issue

After upgrading ONTAP from 9.16.1P1 DAR to 9.16.1P8 NODAR image, the following emergency alerts were observed:

[ec2-lon-napp2:statd:callhome.nse.ak.check.failed:EMERGENCY]: Callhome for AuthenticationKeyCheckFailed, disk "0n.1".
[ec2-lon-napp1:statd:callhome.nse.ak.check.failed:EMERGENCY]: Callhome for AuthenticationKeyCheckFailed, disk "0n.10".

Attempts to synchronize the Onboard Key Manager (OKM) using the available passphrase failed:

Error: command failed: Cluster-wide passphrase is incorrect.

Further disk encryption modification attempts (setting data-key-id to 0x0) also failed with authentication errors:
