Resolving host names with NIM
NIM relies on standard AIX® library routines to perform name resolution. If a network environment uses multiple sources for name resolution, NIM will resolve host names by querying the sources in whatever order is specified for the system.
For example, if a system is configured to resolve host names by first querying NIS, then BIND/DNS, then a local /etc/hosts file, NIM will also follow that order when resolving client host names.
Problems may result if the NIM master and the NIM clients use different orders when querying sources for name resolution. Problems may also arise if a name service is available to one machine but not to another, causing different name resolution sources to be used.
