sndrsyncd(1M) System Administration Commands sndrsyncd(1M)NAMEsndrsyncd - Availability Suite Remote Mirror update resynchronization
daemon
SYNOPSIS
/usr/lib/sndrsyncd
DESCRIPTION
The sndrsyncd 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.
The daemon is notified by the kernel when a network link being used by
Remote Mirror goes down and invokes the sndradm(1M) command with the -u
option to resynchronize all Remote Mirror sets which have autosync
switched on and are using the network link. See sndradm(1M) for details
on how to configure autosync for a Remote Mirror set.
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 synchroniza‐
tion to start if the file system is currently mounted.
EXIT STATUS
0 Daemon started successfully.
>0 Daemon failed to start.
