Working with MasterKeys

Hello,

I find a recent SOL and it explain this command and masterkey with vCMP :

• K73034260: Overview of the BIG-IP system Secure Vault feature

In HA configuration, it's only necessary to used this command on one member of cluster and to sync in all member of cluster.

We just have one interrogation about unit key and storage of unit key for vCMP guest ?

It explain in this article that :

"If no EEPROM is available, for example in the case of a BIG-IP Virtual Edition (VE) system, the system stores the unit key as a hidden file named .unit.key in the /config/bigip/kstore file. The system generates and stores Virtual Clustered Multiprocessing (vCMP) guest unit keys on the vCMP host, and the host unit key, stored in hardware, protects the host master key."

So it doesn't very clear for me if used specific path and file in vCMP host to store the unit key of guest or if it used EEPROM of vCMP host to store unit key of guest vCMP.
