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?
