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

On a congested network, sometimes a newly created IMM object can take some
time to be available on other nodes.
In our test, a new SU is created on SC-1 and unlocked. But sometimes
it fails on a remote node due to:
2017-05-19 13:55:19 SC-2 osafamfnd[258]: ER amf_saImmOmSearchInitialize_o2
failed: 12
To get around this, we will retry on SA_AIS_ERR_NOT_EXIST a few times.
