Description:

1. This article can be regarded as a note, give yourself a reminder, if you need it, you can refer to it.

two。 Suppose the environment is a two-node DAG group, and one of the servers fails and needs to be rebuilt

3.

3.1 the new server needs to be consistent with some of the configurations of the original server. For example, network settings, server names, and division of logical disks. (you can find the original installation path in the ADSI editor)

Reset the computer account in AD (in order to join the domain environment, otherwise it will prompt for the name of the computer that already exists)

3.3 evicting the failed node server in the failover cluster

4. Install a new exchange server using the recovery model

Setup/mode:recoverserver/iacceptexchangeserverlicenseterms

Specific steps:

1. View the database and database replica in the failed server get-mailboxdatabase-server mb02 (existing database) get-mailboxdatabasecopystatus-server mb02 (existing copy) 2. Delete database copy get-mailboxdatabasecopystatus-server mb02 | remove-mailboxdatabasecopy 3. Confirm that the copy has been deleted from get-mailboxdatabasecopystatus-server mb02 4. Delete failed DAG member servers in failover Cluster Administrator this step operates in the GUI interface. (setting up DAG automatically installs failover cluster management) 5. Delete the DAG member server remove-databaseavailabilitygroupserver-identity dag1-mailboxserver mb02 6. Confirm that get-databaseavailabilitygroup 7. Use the recovery model to install the exchange server (prerequisites are the same as the new installation) setup/mode:recoverserver/iacceptexchangeserverlicenseterms 8. After installation, add the server to DAG node 9. 0. Add database copy 10. Verify database copies, dag groups, etc.
