The fs Commands
dto= <destination timeout>
Plays back a delta set based on the time interval specified in
seconds (default=600).
hwm= <high_water_mark>
Specifies a threshold in megabytes (default=600) for generating or
playing back a delta set based on a storage space threshold. The
threshold is the amount of change allowed before triggering delta
set activity. If a value is specified using hwm= and both file
systems are specified in the command line, that value is applied
to both the source and destination file systems.
dhwm= <destination_high_water_mark>
Specifies a threshold in megabytes (default=600) for playing back
a delta set based on a storage space threshold. The threshold is
the amount of change allowed before triggering delta set activity.
autofreeze= {yes|no}
Automatically freezes reads and writes to the <srcfs> when the
SavVol becomes full during replication. File systems that are
frozen are not accessible to clients. The default is no.
autoro= {yes|no}
Automatically mounts the <srcfs> read only when the SavVol
becomes full during replication. The default is no.
qos= <qos>
Specifies the maximum network bandwidth in kilobits per second
that can be used for the replication session.
-failover <srcfs>[:cel=<cel_name>] <dstfs>
Executed from the Celerra Network Server hosting the <dstfs>, fails
over the <srcfs> on the specified Celerra Network Server onto a
<dstfs>. After the failover, the <dstfs> is mounted read/write. If the
<srcfs> is still available at the time of failover, it will be mounted
read-only. Replication is local unless a <cel_name> is specified.
Note: Replication must have been set up between the two file systems on the
two Celerra Network Servers prior to executing a failover.
[ -option <options> ]
Specifies the following comma-separated options:
{ now|sync }
The now option initiates an immediate failover and does not play
back any delta sets. The sync option, executed when both Celerra
Network Servers are running, mounts the source site as
