NAME

6       sndrsyncd  -  Availability Suite Remote Mirror update resynchronization
7       daemon
8

SYNOPSIS

10       /usr/lib/sndrsyncd
11
12

DESCRIPTION

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

NOTES

70       Do not manually stop the sndrsyncd deamon. If you need to manually stop
71       sndrsyncd  perform these steps. This stops both the sndrd and sndrsyncd
72       daemons.
