Restoration in nonproduction environments
If the E5300 Messaging System was in a nonproduction environment prior to the system recovery
and the Exchange data does not have to be retained, the data on the appropriate volumes should
be deleted. This includes the mailbox databases and logs found in the mount points listed under
C:\ExchangeDatabases. The HUB transport database and logs (located on the H:\ drive)
should also be deleted. Use the E5000 Exchange Deployment Tool to create a fresh deployment
of Exchange 2010.
NOTE:
In the Exchange Deployment Tool step to remove the DAG, you must use the ConfigurationOnly
parameter. The command structure is:
Remove-DatabaseAvailablityGroupServer -Identity (yourDAG) -MailboxServer
(server being recovered) -ConfigurationOnly:$True -Confirm:$False
- If an error message displays that there must be minimum of two servers in a DAG (due to the
DatacenterActivationMode value being set to DagOnly), you can turn this off by issuing the
following command:
Set-DatabaseAvailabiltyGroup –Identity (yourDag)
–DatacenterActivationMode Off
After restoring the server and the DAG is operational, remember to set
DatacenterActivationMode back to DAGOnly.
Restoration in production environments
If the E5300 Messaging System was in a production environment and the Exchange data must to
be retained, follow the appropriate Exchange recovery steps for your situation. Remember that the
E5000 system uses a multirole Exchange configuration with the Client Access Server (CAS), Hub
Transport Server (HT), and Mailbox Server (MBX) roles installed on each of the two nodes. Do not
use the E5000 Exchange Deployment Tool in this situation. You can recover a lost Exchange server
by using the Setup /m:RecoverServer switch in Microsoft Exchange Server 2010. See http://
technet.microsoft.com/en-us/library/dd638206.aspx for more information.
