The rplcontrol commands described above can be specified by name (with the
-s option) or by a number (with the -c option).
The -h ip|hostname option can be used to run the command on a specific node.
The remainder of this chapter shows some examples of using the rplcontrol
commands.
Determine when replication is complete
To determine whether a particular replication cycle has completed, check for the
changed files on the destination cluster.
Restore replicated files
To restore files from the destination replica back to the source cluster, take these
steps:
1. Stop replication on the source cluster. This command transitions replication to
state 4 (stopped).
# rplcontrol -s stop
2. Use a file transfer method (for example, scp, ftp, tar, cpio) to copy the files
back to the source cluster.
3. Restart replication on the source cluster. This command returns replication to
state 2 (running).
# rplcontrol -s restart
Replication does not provide tools to analyze or report the deltas between the source
cluster and the destination cluster.
It is possible to configure the destination to now be a source, and replicate in the
other direction. There is not an advantage over scp if there is total data loss on the
source. There is an advantage if the data loss is large but not total, as some files will
not need to be replicated.
Start or stop replication
In general, replication is started on a node when HP Scalable NAS is started and
you should seldom need to start or stop it manually. However, the rplcontrol
command can be used to start or stop replication on a particular node or on the
entire cluster if needed.
