Well you can do it on a per secondary basis as well, but that does not
solve the times. I've always used rsh to do this kind of stuff in the
past but the security implications scare me now.

Subject: Re: Throttling
Is there a global method of doing this, or do I have configure
each of my snapmirror vols separately?
According to the man page anyway, the snapmirror throttle command is on
a per volume basis.
Also, never actually scripted SSH before, I cant find any decent
pointers, is this a regular thing to do with filers?
Yup, this is a standard thing for me anyway. Setting up ssh keys to gain
passwordless logins to the filers for scripting is also really useful.
You could also probably use the Netapp API to do this type of thing.
Another alternative that I though of after reading this tidbit of the
snapmirror throttle man page:
The new value will be used only for the current
transfer. The next scheduled transfer will use the
kbs value specified in the snapmirror.conf file. If
the value for the kbs option in the snapmirror.conf
is changed while transfer is going on, then the new
value will take effect within two minutes.
Is that you could have a simple script which just changes all the
throttle values in the snapmirror.conf file at the time you want the
values throttled and sets them back when that timeframe is over.
Good luck,
Romeo

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

Thanks
