Application Managed Encryption - ML6020

Any Dell ML6020 Library firmware starting with a 6 (660G in this case) -  Encryption default is "None"

How do you change the default to Application Managed ?  I currently cannot change it from Web client.

From the Web Client - Setup - Encryption - Partition - Configuration - at this point it stops with error message EKM is required. 

Dell documentations says EKM is not required when using Application Managed Software for Encryption.

BUT in order to use Application Managed software I need the Encryption set to  Application Managed, not NONE.

This is not an issue with ML6020 firmware level 585G.GS003 - the default setting for encryption is "Application Managed"   

What happened from 5XXX to 6XXX library firmware ?  Need level 6XXX for LTO6 tape drives
