Hi, I was planning my Exchange 2010 (sp1) HA architecture, but I stumble in something unexpected (due to my ignorance) and I'm looking for advice.
Here is the situation now:
I have a virtual exchange server with HUB and CAS roles and another phisical exchange server with mailbox role installed. They are both in my primary site.
Now we have a remote site and a remote vmware hosts to use for HA and disaster recovery purposes. The internal network of the DR site is different from mine and it's natted too. More precisely my primary network is 192.168.100.0/24 and the DR network is 192.168.60.0/24 natted with 192.168.113.0/24.
The DR domain controller and the DR AD site are already in place.
My idea was:
- to use veeam replication to create a replica of the first exchange server, the virtual one of course, with CAS and HUB roles. I thought to use the veeam network remapping tool to change che server IP address in case of failover.
- to install a new exchange server in the DR site with mailbox role only and configure a DAG
I thought it was brilliant.
It was not..
Since i cannot create the veeam replica right now (long story) I tried to install the DAG and here we are with my problems.
Error:
Setup encountered a problem while validating the state of Active Directory. Could not find Active Directory site to which this server belongs.
This is weird, because I have no problems with site replications etc.
Warning:
Setup did not detect an existing Huh Transport Server role installed in Active Directory site 'DR'...
Setup did not detect an existing Client Access Server role installed in Active Directory site 'DR'...
And that's my real problem. I didn't remember that Exchange is site based.
What are my options now?
Could I install CAS and HUB just to complete the install and then ignore them or they will cause problems with my primary site?
In the end, what do you think should I do?
At this point I could re-think the all thing.
Thank you and sorry for the grammar
