Appendix D: Using a
non-Microsoft DNS Server
In order to update Windows-based Active Directory-Integrated DNS
records, the account specified must be a domain user account with
appropriate permissions. If you are not using Windows-based DNS (that is, if you are using the
/altdns
switch), a domain user account is not required.
The following steps provide one example of how you can use a BIND DNS client for DNS
failover/failback scripting.
1. Go to www.isc.org and download the appropriate BIND DNS client.
2. Install the BIND client on the target Storage Mirroring server.
3. Set a PATH statement for the BIND directory to ensure that it runs every time the executable is
called.
4. Create your failover and failback batch files in the
<drive>:Program
Files\StorageWorks\Storage Mirroring
directory and add the following line for
failover:
nsupdate.exe “<drive>:Program Files\StorageWorks\Storage
Mirroring\dtdnsover.txt”
Add the following line for failback:
nsupdate.exe “<drive>:Program Files\StorageWorks\Storage
Mirroring\dtdnsback.txt”
5. Create two new .txt files in the
<drive>:Program Files\StorageWorks\Storage
Mirroring
directory.
a. Create a file called dtdnsover.txt that includes the following.
b. Create a file called dtdnsback.txt that includes the following.
6. Modify the .txt files appropriately with the source/target server names, IP addresses, and
fully-qualified domain names.
7. Change the Storage Mirroring service on the target server to a domain account that has rights to
modify BIND DNS. Stop and start the service to have it take effect.
Using /altdns
If you are using a non-Microsoft DNS server (such as Unix) or if you are in a non-domain configuration
(such as a workgroup), you can use the /altdns option to disable Application Manager from checking
and utilizing Microsoft DNS.
To run Application Manager in this mode, from command prompt, enter
dtam /exchange
/altdns
. This command must be run from the location where the Application Manager is installed
(the default installation location is either \Program Files\Storage Mirroring\ or \Program
files\Application Manager).
