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. 35 .SH EXIT STATUS 36 .ne 2 37 .na 38 \fB\fB0\fR\fR 39 .ad 40 .RS 13n 41 Daemon started successfully. 42 .RE 43 44 .sp 45 .ne 2 46 .na 47 \fB\fB>0\fR\fR 48 .ad 49 .RS 13n 50 Daemon failed to start. 51 .RE 52 53 .SH FILES 54 .ne 2 55 .na 56 \fB\fB/lib/svc/method/svc-rdcsyncd\fR\fR 57 .ad 58 .sp .6 59 .RS 4n 60 Shell script for starting \fBsndrsyncd\fR. 61 .RE 62 63 .sp 64 .ne 2 65 .na 66 \fB\fB/lib/svc/method/svc-rdc\fR\fR 67 .ad 68 .sp .6 69 .RS 4n 70 Shell script for stopping \fBsndrsyncd\fR. 71 .RE 72 73 .SH ATTRIBUTES 74 .LP 75 See \fBattributes\fR(5) for descriptions of the following attributes: 76 .sp 77 78 .sp 79 .TS 80 box; 81 c | c 82 l | l . 83 ATTRIBUTE TYPE ATTRIBUTE VALUE 84 _ 85 Interface Stability Evolving 86 .TE 87 88 .SH SEE ALSO 89 .LP 90 \fBiiadm\fR(1M), \fBsndradm\fR(1M), \fBsndrd\fR(1M), \fBsvcadm\fR(1M), 91 \fBds.log\fR(4), \fBrdc.cf\fR(4), \fBattributes\fR(5) 92 .SH NOTES 93 .LP 94 Do not manually stop the sndrsyncd daemon.
