7. ## Managing Differences Between Files That Are Not Shared Files on a shared file system have the same content, as viewed from the master node and vice-master node. The following files are stored locally on the master node and vice-master node. The files must contain identical information, but they are not shared. `cluster_nodes_table` Contains the nodeid and node name of each peer node. For more information, see the `cluster_nodes_table`(4) man page. `/etc/hosts` Contains the hostnames of all nodes on the cluster network. For more information, see the `hosts`(4) man page. `nhfs.conf` Describes the cluster configuration, including network interfaces, mirrored disk partitions, and the floating external address. For more information, see the `nhfs.conf`(4) man page. To manage differences that exist between files that are not shared, performing the following procedure. ### To Manage Differences Between Files That Are Not Shared Log in to the master node as superuser. Open or create the `/SUNWcgha/remote/etc/nhadmsync.conf` file in a text editor. Specify the names of the files that you want to compare by adding them to the `nhadmsync.conf` file. For more information, see the `nhadmsync.conf`(4) man page. Save the `nhadmsync.conf` file and exit the text editor. Log in to the vice-master node, as superuser. Repeat Step 2 through Step 4. Verify that the listed files are the same on the master node and the vice-master node:
       # nhadm synccheck
   - If the files are not identical on the master node and vice-master node, analyze the differences between the copies of the files. If the differences between the files are acceptable, accept them:
         # nhadm syncgen
2. If you accept the differences between two files, the differences will no longer be signaled by the `nhadm synccheck` command. For more information about the `nhadm` command, see the `nhadm`(1M) man page. ## Using the Naming Services This section provides guidelines for using naming services on the Foundation Services. If you use a naming service such as the Network Information Services (NIS) or the Domain Name System (DNS), avoid conflicts between the names of nodes and services by doing the following: Verify that the names of nodes specified in the `/etc/hosts` file are used before node names generated by your naming service. The name assigned to a node during cluster configuration must not conflict with the name assigned to a node by the naming service. Verify that the entries for `hosts`, `network`, and `services` in the `/etc/nsswitch.conf` file are set as follows:
       [...]
       hosts:      files [...]
       network:    files [...]
       [...]
       services:   files [...]
