6 sndrsyncd - Availability Suite Remote Mirror update resynchronization
7 daemon

10 /usr/lib/sndrsyncd
11
12
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.
