Restore exchange 2013 DAG node for testing
I have restored a DAG node in a 2 node cluster (with file share witness) to test environment.
This environment has different VLAN so I had to change the IPs of all servers in this test environment.
But Databases or DAG name are not coming online.
I ran the command "sset-databaseavailability
But the command failed and the new file share directory is empty. it gave the following error:
"An error occured while attempting a cluster operation. Error: Cluster API: OpenByNames('server1', 'server2) failed for each server. Specific exceptions" 'An error occured while attempting a cluster operation. Error: CLuster API failed: "Opencluster(server1) failed with 0x6d9'. Error: There are no more endpoints availbale from the endpoint mapper". "An error occurred while attempting a cluster operation. Error: Cluster API failed: "opencluster(server2) failed 0x6ba. Error:RPC server is unavailable.
And as there is no quorum the DAG name won't come online.
What can I do to get this DAG working with only single node I restored?
Do I need to do any changes in Active directory/ DNS entries for this DAG?

I assume your end goal is to restore one production Exchange server into test environment?

HI Steve,
I had restored the DC in this test environment. I wanted to change the witness directory without restoring the witness server itself as it was quite huge. But at the end I restored the witness server virtual machine but with just the C drive as the witness directory was on that drive, and got it working.
I had to change the DAG IP to the new VLAN along with the server IP and with these changes and the DNS server in this test VLAN reflecting these changes, I was able to get the cluster and databases up.
Thanks for helping with this one.
