Administrator's Guide
NOTE: When you reach this screen while deploying to the bay 1 server, select First blade.
The Exchange Deployment Tool automatically detects whether any are found in the existing
Exchange organization (when existing is selected). When you reach this screen while deploying
to the bay 2 server, select Second blade, and then enter the name of the bay 1 server (not the
name of the bay 2 server).
Complete each item on this screen as needed for your deployment:
• New or existing Availability Group (DAG) name. The Exchange Deployment Tool
automatically detects if any are found in the existing Exchange organization. Accept the
default name or enter a new name of one already exists.
• Availability Group IP address. Using an IP address of 0.0.0.0 configures the DAG to use
DHCP. You can update the configured IP address later using the Exchange Management
Shell, or additional addresses can be added later using the Set-AvailabilityGroup
PowerShell command.
• Witness Server name. See
nl
http://technet.microsoft.com/en-us/library/dd351107.aspx for information about special
considerations if placing the suggested default Witness Server on a domain controller:
• Witness directory. Specify the local path on the Witness Server.
• name prefix. Use the suggested default or enter a new name. The Exchange Deployment
Tool appends numbers to the name and verifies that the name is unique at the organization
level (an Exchange 2010 requirement).
• Client Access Server (CAS) is Internet facing. For more information, see
nl
http://technet.microsoft.com/en-us/library/dd351198.aspx for more information.
• New or Existing CAS array. Enter a name for New or select from the drop-down for
Existing (if detected).
