   7 .SH NAME
   8 sndrsyncd \- Availability Suite Remote Mirror update resynchronization daemon
   9 .SH SYNOPSIS

  15 .SH DESCRIPTION
  16 .LP
  17 The \fBsndrsyncd\fR daemon automates update resynchronization after a network
  18 or machine failure and invokes Point-in-Time Copy copies when needed to protect
  19 the data volumes being updated during a resynchronization.
  20 .sp
  21 .LP
  22 The daemon is notified by the kernel when a network link being used by Remote
  23 Mirror goes down and invokes the \fBsndradm\fR(1M) command with the \fB-u\fR
  24 option to resynchronize all Remote Mirror sets which have autosync switched on
  25 and are using the network link. See \fBsndradm\fR(1M) for details on how to
  26 configure autosync for a Remote Mirror set.
  27 .sp
  28 .LP
  29 The daemon is also notified when any Remote Mirror resynchronization starts or
  30 completes. The daemon takes Point-in-Time Copy snapshots, if configured in the
  31 Availability Suite configuration file. On a secondary server, the daemon checks
  32 if a file system is currently mounted on the secondary volume and informs the
  33 kernel not to allow the synchronization to start if the file system is
  34 currently mounted.

  92 .SH NOTES
  93 .LP
  94 Do not manually stop the sndrsyncd daemon. If you need to manually stop
  95 sndrsyncd perform these steps. This stops both the \fBsndrd\fR and
  96 \fBsndrsyncd\fR daemons.
