HP MSA controller remote management?

Here's our problem, the data center loses power, and is running on the UPS batteries.  We have 45 minutes to bring the devices down before the batteries runs out of power.

How can we shutdown the MSA1000 controller and the disk drives the controller manages remotely?

I've done some reading on using Insight Manager, but I don't find anything on being able to power off an MSA controller. Can you shut it down using Insight Manager?

 I've also done some reading on the MSA1000, it mentions that the only way to really stop the flow of power to it is to unplug it.  I've read the CML manual and I don't find a shutdown command.  Can you shut it down from the command line?

And once it's shutdown can you power it up remotely?  Seeing how it doesn't really lose power unless it unplugged, I'm hoping you could power it up.

The shelves that house the disk drives, I don't remember them having a power button.  I think we just unplugged them to shut them down.  Is there some kind of device we could plug them into that could manage powering them off and on?

While we have a Liebert UPS to manage power to the data center, we don't have a generator to back it up.  When the power company kills the power for 12 hours, not much you can do without a generator.

You can just let it run out of power since it's got internal 72 hour battery backed cache.

If it's a case of wanting to power it off to increase the runtime on other kit then you can use a remote power switching PDU to do that once you have shutdown the hosts using it.

If you're after making sure the cache is flushed because you're going to have more than 72 hour power down then that isn't easy without access to the power button which initiates a clean shutdown. You can force a cache flush per LUN by changing its preferred path in a dual controller active/active setup (example on page 33 shows cache flush task when preferred path changed). You can also check to see if the cache is flushed using show this_controller and show_other controller. Cache is flushed soon after host access stops anyway, to be safe you can leave it powered on for 10 minute after the hosts are shutdown.

Thanks for the details regarding how the cache works.

The power switching pdu's should do the trick to power them off.  I googled and found WTI's site.
