.SH NAME
sndrsyncd \- Availability Suite Remote Mirror update resynchronization daemon
.SH SYNOPSIS
.LP
.nf
\fB/usr/lib/sndrsyncd\fR 
.fi

.SH DESCRIPTION
.sp
.LP
The \fBsndrsyncd\fR daemon automates update resynchronization after a network
or machine failure and invokes Point-in-Time Copy copies when needed to protect
the data volumes being updated during a resynchronization.
.sp
.LP
The daemon is notified by the kernel when a network link being used by Remote
Mirror goes down and invokes the \fBsndradm\fR(1M) command with the \fB-u\fR
option to resynchronize all Remote Mirror sets which have autosync switched on
and are using the network link. 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.

Do not manually stop the sndrsyncd deamon. If you need to manually stop
sndrsyncd perform these steps. This stops both the \fBsndrd\fR and
\fBsndrsyncd\fR daemons.
