Run "options replication", note that the values are kiloBYTES/second:
 
toaster> options replication
replication.throttle.enable off
replication.throttle.incoming.max_kbs unlimited
replication.throttle.outgoing.max_kbs unlimited
 
replication.throttle.enable
Enables global network throttling of snapmirror and snapvault transfers. The default value for this options is off.

replication.throttle.incoming.max_kbs
This option specifies the maximum total bandwidth used by all the incoming (applied at destination) snapmirror and snapvault transfers, specified in kilobytes/sec. The default value for this option is unlimited, which means there is no limit on total bandwidth used. This option is valid only when the option replication.throttle.enable is on.

replication.throttle.outgoing.max_kbs
This option specifies the maximum total bandwidth used by all the outgoing (applied at source) snapmirror and snapvault transfers specified in kilobytes/sec. The default value for this option is unlimited, which means there is no limit on total bandwidth used. This option is valid only when the option replication.throttle.enable is on.

Hi Toasters

We run our snapmirrors overnight mostly, to a DR site which just happens to be a working office. Sometimes they're still running in the morning, and they eat all the bandwidth. We throttle them in the snapmirror management.  We do this manually and its a pain and sometime we forget etc.

What I'd like to do is (probably) script and schedule some SSH commands to set the bandwidth throttle on the volumes so that they are restricted during working hours, but open out of hours. Is there a global method of doing this, or do I have configure each of my snapmirror vols separately?

Also, never actually scripted SSH before, I cant find any decent pointers, is this a regular thing to do with filers?

Thanks
Dave Ashton
