-database {hosts|group|passwd|netgroup|namemap} - Name Service Switch Database

Examples

The following example modifies the name service source ordering for the hosts database on a Vserver named vs0. The order of looking up the sources is changed to only DNS.

cluster1::> vserver services name-service ns-switch modify -vserver vs0 -database hosts -sources dns

The following example modifies the name service source ordering for the passwd database on a Vserver named vs1. The order of looking up the sources is changed to LDAP followed by NIS.

cluster1::> vserver services name-service ns-switch modify -vserver vs1 -database passwd -sources ldap,nis
