HP StorageWorks Enterprise File Services WAN Accelerator 3.0.4 Command-Line Interface reference manual (AG421-96004, March 2007)

92 4 - CONFIGURATION-MODE COMMANDS
NOTE: Data is replicated only from the master HP EFS WAN Accelerator to the backup; not
vice versa.
NOTE: All operations occur in the background and do not disrupt operations on any of the
systems.
The no command option disables data store synchronization.
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.
IMPORTANT: 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.
IMPORTANT: To implement data store synchronization 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.
