How to Configure the Name Service Switch

Perform this task on each node in the cluster.

1. Become superuser on the cluster node.

2. Edit the /etc/nsswitch.conf file.

   1. Verify that cluster is the first source look-up for the hosts and netmasks database entries.

      This order is necessary for Sun Cluster software to function properly. The scinstall(1M) command adds cluster to these entries during installation.

   2. (Optional) For the hosts and netmasks database entries, follow cluster with files.

   3. (Optional) For all other database entries, place files first in look-up order.

   Note -

   Performing Step b and Step c can increase availability to data services if the naming service becomes unavailable.

   The following example shows partial contents of an /etc/nsswitch.conf file. The look-up order for the hosts and netmasks database entries is first cluster, then files. The look-up order for other entries begins with files.

   # vi /etc/nsswitch.conf ... passwd:     files nis group:      files nis ... hosts:      cluster files nis ... netmasks:   cluster files nis ...

3. Update the /etc/inet/hosts file with all public hostnames and logical addresses for the cluster.
