[Praveen] Based on discussion on ticket #1828 related to CLM
initialization, I remember this API does not return ERR_UNAVAILABLE even
on a CLM locked node also. This provision is to enable application on
CLM locked node to perform tracking of CLM status of nodes.
But I think even CLM Agent can return this code when CLMS server has not
got node related information from CLM agent and in that case CLMS will
return ERR_UNAVAILABLE. If it is not so, then I think we are not
required to handle rc == SA_AIS_ERR_UNAVAILABLE.
Thanks,
Praveen
