NSLookup
The nslookup utility can verify that the SA9200 is correctly resolving
www.somedomain.xyz-ex.com:
NOTE: If the SA9200
was not configured with a
primary name server
during setup from the
Boot Monitor, the
nslookup command fails.
HP SA9200# nslookup
www.somedomain.xyz-ex.com
Server: server1.xyz-ex.com
Address: 10.168.16.4
Name: www.somedomain.xyz-ex.com
Address: 10.168.16.23
Configure DNS Servers
The existing DNS server or servers must be correctly configured to
work with the SA9200s. Entries need to be made that delegate the
responsibility of resolving DNS queries for www.xyz-ex.com to the
SA9200s. This can be done in one of two ways. The first way is to
delegate the entire zone to the SA9200. This works fine as long as
only type A records need to be returned for this zone. The SA9200 is
a high performance specialized DNS server and supports only the
more common type A records.
The recommended way of configuring your existing DNS server is
delegate partial authority by aliasing. All of the SA9200s (both
primary and all secondaries) must be included in the authority record
(NS) portion of the delegation.
