NAME

       sndrsyncd - 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 synchronization to start if the file system is currently mounted.

EXIT STATUS

       0	    Daemon started successfully.

       >0	    Daemon failed to start.

NOTES

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

	 # svcadm disable svc:/system/nws_rdc

	 # svcadm disable svc:/system/nws_rdcsyncd

       Do  not	manually  start or restart the sndrsyncd deamon. If you need to manually start sndrsyncd perform these steps. This starts both the
       sndrd and sndrsyncd daemons.

	 # svcadm enable svc:/system/nws_rdc

	 # svcadm enable svc:/system/nws_rdcsyncd

       See svcadm(1M) for additional information.
