Windows DNSCMD command
DNS updates can be added to your failover and failback scripts by using the Windows
DNSCMD command as long as dynamic updates are enabled on the DNS zone and the
account running the Storage Mirroring service is a member of the DNSAdmins security
group. (See your Microsoft documentation to verify if dynamic updates are enabled.) Add
the following commands to your failover and failback scripts to delete the host and
reverse lookup entries and add new entries associating the source to the target.
l
dnscmd DNS_server’s_FQDN /RecordDelete DNS_zone source_server_name
A source_server_IP_address /f
l
dnscmd DNS_server’s_FQDN /RecordDelete www.xxx .in-addr.arpa zzz.yyy PTR
source_server’s_FQDN /f
l
dnscmd DNS_server’s_FQDN /RecordAdd DNS_zone source_server_name A
target_server_IP_address
l
dnscmd DNS_server’s_FQDN /RecordAdd aaa.bbb .in-addr.arpa ddd.ccc PTR
source_server’s_FQDN
Use the following variable substitutions.
l
DNS_server’s_FQDN — The fully qualified domain name of the DNS server
l
DNS_zone —The name of the DNS zone
l
source_server_name —The name of the source server
l
source_server_IP_address —The IP address on the source
l
www.xxx —The first two octets of the source’s IP address. For example, if the
source’s IP address is 192.168.1.108, this variable would be 192.168.
l
zzz.yyy —The last two octets, in reverse order, of the source’s IP address. For
example, if the source’s IP address is 192.168.1.108, this variable would be 108.1.
l
source_server’s_FQDN —The fully qualified domain name of the source server
l
target_server_IP_address —The IP address on the target
l
aaa.bbb —The first two octets of the target’s IP address. For example, if the target’s
IP address is 116.123.2.47, this variable would be 116.123.
l
ddd.ccc — The last two octets, in reverse order, of the target’s IP address. For
example, if the target’s IP address is 116.123.2.47, this variable would be 47.2.
For example, suppose you had the following environment.
l
Full qualified domain name of the source—Alpha.domain.com
l
Source IP address—192.168.1.108
l
Fully qualified domain name of the target—Beta.domain.com
l
Target IP address—116.123.2.47
