NetApp SnapMirror agent<br />
The NetApp SnapMirror agent monitors the replication state of filer devices.<br />
When a failover occurs, the agent reverses the direction of replication.<br />
NetApp SnapMirror agent is configured as a resource of type NetAppSnapMirror.<br />
Dependency<br />
The NetApp SnapMirror resource depends on the NetApp Filer resource for<br />
operation.<br />
Agent functions<br />
Online<br />
If the state of the local filer device is SOURCE, the agent creates a lock<br />
file to indicate that the resource can come online. This effectively makes<br />
the devices writable for the application.<br />
If the state of the local filer is SNAPMIRRORED, the agent attempts to<br />
reverse the direction of replication by changing the state of the local filer<br />
to SOURCE and that of the original source to SNAPMIRRORED.<br />
If the original source filer is down, the agent performs a mirror breakoff<br />
to enable local write access, if the filer is not already broken off.<br />
If the original source returns to life, you must resynchronize the data<br />
manually.<br />
Offline<br />
Removes the lock file. The agent does not perform any filer operations<br />
because an offline function does not necessarily indicate an intention to<br />
give up the devices.
