See \fBsndradm\fR(1M) for details on how to configure autosync for a Remote Mirror set. .sp .LP The daemon is also notified when any Remote Mirror resynchronization starts or completes. The daemon takes Point-in-Time Copy snapshots, if configured in the Availability Suite configuration file. On a secondary server, the daemon checks if a file system is currently mounted on the secondary volume and informs the kernel not to allow the synchronization to start if the file system is currently mounted. .SH EXIT STATUS .sp .ne 2 .mk .na \fB\fB0\fR\fR .ad .RS 13n .rt Daemon started successfully. .RE .sp .ne 2 .mk .na \fB\fB>0\fR\fR .ad .RS 13n .rt Daemon failed to start. .RE .SH FILES .sp .ne 2 .mk .na \fB\fB/lib/svc/method/svc-rdcsyncd\fR\fR .ad .sp .6 .RS 4n Shell script for starting \fBsndrsyncd\fR. .RE .sp .ne 2 .mk .na \fB\fB/lib/svc/method/svc-rdc\fR\fR .ad .sp .6 .RS 4n Shell script for stopping \fBsndrsyncd\fR. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
