Subject: Re: SnapMirror throttle schedule in cDOT?

options.snapmirror ?   Is this available to be modified at the node level?  If so, that's very interesting.

I would just write the script to change the dynamic value in options.snapmirror and schedule it via cron.  I don't know of any native way.

Hi,

Anyone know if there’s a way to change a throttle value on a snapmirror relationship based upon time-of-day? As an example, between the hours of 7 AM and midnight throttle the transfers to 2.5MB/s and between midnight and 7 AM, throttle the transfers to 10MB/s.

There was a way to create a throttle policy in the old NMC, but there doesn’t seem to be a way to do it with cDOT, at least as far as I can see.

I’m considering an external script that will modify the throttle based on time-of-day, but, particularly with long running initializations, the process has to be stopped “aborted” and started again in order for the new throttle value to get picked up. Without logic in the script I could end up re-initializing the snapmirror relationship if the init finishes and I don’t stop the script.
