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.

[AVM] Even we have problem of newly created IMM object is taking some time to be available on other nodes it will be a implementation problem and it is not related to IMM specification .

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?

[AVM] Again, this is also not related to IMM specification , if we resolve above this issue will not rise .

Gary, Is this issue you are facing in case where you are creating object on one node and admin operation performed on different node ?
or on same same node ?

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.
