5. Click Apply to apply your settings to the running configuration. (Apply your
settings to test a new configuration before saving them permanently.)
6. Click Save to save your settings permanently or click Reset to return the settings
to their previous values.
Automated Online Datastore
Settings Enable Automated Online Datastore Synchronization. Specify this option to enable
automated data store synchronization. Data store synchronization ensures that each data
store in your network has warm data for maximum optimization. All operations occur in
the background and do not disrupt operations on any of the systems.
There are the following phases in synchronization:
• Catchup. Copies data that is already on the master to the backup HP EFS WAN
Accelerator. This process stops when all the old data from the master is copied to the
backup HP EFS WAN Accelerator.
• Keepup. Runs continuously copying new data that the master appliance encounters to
the backup HP EFS WAN Accelerator.
IMPORTANT: The HP EFS WAN Accelerators must be the same model; models
running different versions of the software will not synchronize (for example v2.x to 3.x).
Synchronization does not guarantee that all data objects are replicated—synchronization
runs in the background, if the HP EFS WAN Accelerator is under load, all data may not
be replicated.
NOTE: If you are setting up automated data store synchronization for the first time, the
HP EFS WAN Accelerator service is halted on the backup HP EFS WAN Accelerator.
You must restart the HP EFS WAN Accelerator service on backup HP EFS WAN
Accelerators. If you restart the service with a clean data store you must shutdown the
backup HP EFS WAN Accelerator, power it off, and power it on.
NOTE: In out-of-path configurations, you must designate an HP EFS WAN Accelerator
as a backup appliance, either by enabling failover support or by designating it as an out-
of-path backup appliance, to implement data store synchronization.
Current Appliance is the. Select Master or Backup from the drop-down list. You must
specify the primary IP address for the master and backup appliance.
IMPORTANT: If you have multiple bypass cards installed in your appliance you must
specify the inpath0_0 interface.
Other Appliance’s In-path IP Address. Specify the backup or master HP EFS WAN
Accelerator IP address. You must specify the primary IP address for the master and
backup appliance.
You must specify the primary (or AUX if you have enabled this option) IP address for the
HP EFS WAN Accelerator. For detailed information, see
“Setting the Primary Interface”
on page 52 .
IMPORTANT: If you have multiple bypass cards installed in your appliance you must
specify the inpath0_0 interface.
Synchronization Port. Specify the port number for the HP EFS WAN Accelerator from
which you want to replicate data. The default value is 7744.
Reconnection interval. Specify the number of seconds. The default value is 30.
