You can do this be using the Stop-Service clussvc or by opening the Services app. So, after you have stopped the cluster services, you need to rest the DAG with the Restore-DatabaseAvailabilityGroup command, as given below.
Depending on the resources of servers, connectivity between servers and network speed, this process might take some time to finish. Now, you need to remove restriction and activate the databases to start the replication process. This is the most crucial part of the restore as the databases will be mounted and resume the database copy. If you are planning to restore the failed servers, you need to install Exchange Server , Windows Cluster Services and configuration of the network on new servers.
The next command i. Set-DatabaseAvailabilityGroup will make the member server an effective part of the cluster. The above command must be executed on all the new members. In this example, these are EX01 and EX Of course, this could be the ideal scenario where during the servers going offline, there was no damage to the databases. If this is the case, the databases will not mount. When you try to add EXB to the database availability group, you can see the steps in the log file it creates on the server:.
The log shows that both servers listed have the same operating system version; both servers are running datacenter. The second server was added to the database availability group without an issue. This will bring up a new window, as shown below:. You can see the values are the same as when you did it in the Exchange Management Shell, except here you specify Once you click Save, it will create the object.
You should see a window similar to the image below:. Now that you have created your database availability group, you can add copies of your mailbox stores. Edward van Biljon is an experienced messaging specialist working in the IT and services industry.

Edward van Biljon November 4, Once you reboot and try again, the member server will be added successfully. If you do not want to have Exchange manage your network, then you need to click the button to create a new network for Exchange to use.
Now that your DAG is in place you can go and create copies for your databases. Remember that the storage needs to be the same on all your servers. Seeding should be quick as the database is new and small. Again, if you cannot create copies, check that your firewall or AV is not blocking it.
If you want to remove a member server from a DAG, you need to first remove the database copies and allow replication to take place, then you can remove the node from the DAG. Please do not go into Failover Cluster Manager and evict the node.
This will only be required if you are recovering a server and could not remove it from the DAG cleanly. Below is a sample of what it will look like using PowerShell:. Edward van Biljon is an experienced messaging specialist working in the IT and services industry.
