    I opened a ticket with F5 support and Peter (from London) helped me out.

     

    The procedure I was using to reset the master key was to issue the command "tmsh modify sys crypto master-key prompt-for-password" and then use the hash from the guest as the password. The correct procedure is to use "f5mku -r <hash>" on the new guest. After doing that, the UCS file was able to load.

     

    Additionally some cool optimizations that I learned from Peter that really helped with the performance of AVR and the GUI:

     

    tmsh modify sys db avr.stats.internal.maxentitiespertable value 1024

    tmsh modify sys db provision.extramb value 2048;tmsh save sys config

    tmsh modify sys db restjavad.useextramb value true

    tmsh modify sys db provision.tomcat.extramb value 100

  1. Recently during our BCP process I encountered the same and reboot fixed it. Did you already try a reboot​? Also, do you need to issue no-license no-platform-check as well?

Thanks Sanjay. Unfortunately rebooting the guest isn't the fix in this situation. The UCS wouldn't load at all, the guest would be in an INOPERATIONAL state, and I'd delete and recreate the guest.
