[!INCLUDEappliesto-ss-xxxx-xxxx-xxx-md] This topic applies to the General tab of both the New Availability Group dialog box and the Availability Group Properties dialog box. The New Availability Group dialog box enables you to create a new availability group without using the [!INCLUDEssAoNewAgWiz]. The Availability Group Properties dialog box enables you to view and alter the configuration of an existing availability group.
To view availability group properties

Availability Mode
The availability mode of the replica, one of:
Asynchronous commit
The primary replica can commit transactions without waiting for the secondary to write the log to disk.
