Hi Praveen
From talking with Zoran/Hung, the IMM behaviour is expected and correct.
I’m not sure about the last question.
As you know, in AMFND, the trigger to read from IMM is from an AMFD message.
The CCB could be committed on the node where active AMFD resides, so I guess
the admin op would be accepted regardless of the answer to your question.

Hi Gary,
Is there any ticket in IMM for any related issue?
Both creation of SU and admin operation on it will go through IMM only.
I do not know how IMM handles it and how IMM spec talks about it.
Does IMM spec allow admin operation on a entity for which all synced
IMMNDS (leaving non synced IMMNDS on the nodes joining the cluster) are
not updated?
Thanks,
Praveen
