DNS script help

The node alias currently has functionality to register an A or C record in DNS. Please view the EMC AutoStart Administrator's guide for further details and confirguration information.

Hello Sheing - is this a Windows or UNIX based cluster? For windows take a look at "dnscmd" utility on microsoft technet or just search for a way to update the dns record from the command line. Of course, depending on the setup of your environment this may not be allowed. In any case for WAN failover it is always advised to to the failover manually.
Emilio - the built in dns update mechanism will not help here as we need to change the IP address after failover.

Hi,


After a lot of pain with a geographically dispersed AutoStart (Asia - UK) and (USA - UK), can safely say that if this is a Windows cluster that use call the MS Windows tools to manage the DNS entries. Assuming that the IP subnet changes across location, then you will need to make two call - firstly delete the current entry and then secondly add the new details.

Also, if you resource group contains the virtual IP address then use the name version and not the numeric version - that is use AutoStart to query the DNS for the address to use and not code this in to the resource group.

Hope this helps
