DESCRIPTION fs_replicate starts, stops, refreshes and modifies replication
instances, and displays information for the source and destination file
systems.
fs_replicate fails over and reverses replication instances, and
resynchronizes a replication instance after it is has been halted.
Replication takes place locally unless a remote Celerra Network
Server name is specified.
OPTIONS -list
Lists all the replication instances. An inactive state for a file system
indicates that the replication or playback service is not running.
-start <srcfs>[:if=<interface>|:ip=<ip_addr>]
<dstfs>[:cel=<cel_name>[:if=<interface>|:ip=<ip_addr>]]
Starts replication on the source file system, <srcfs>, to the destination
file system, <dstfs>. The <interface> is the name of the interface used
for the transfer of delta sets. See server_ifconfig to obtain the interface
