question came in from a customer via twitter - Jason G., if you are here, feel free to chime in further!
I've reached out to our VP of Support for clarification. Here is the response I have received at this time:
1) if both controllers are powered on and power loss occurs: when power is restored, controllers will power on and services will recover.
2) if array halt (Shutdown) command is given, controllers will power off. The power button must be depressed to resume operation in all cases in this scenario
Thank you rod for the quick reply!
Anything would do to get the ability to remotely start the Nimble as a graceful shutdown since the Nimble has no ILO or Drac like card.
A single IP outlet, a IP PDU, a IP powers strip. Would any of those work?
Any other recommendations?
Could Wake on LAN be enabled?
Sure, I used to use APC PDUs that were metered and connected to my network. This would allow me to shutdown hosts/storage/etc. gracefully and then make sure power was off. I also used this often times for modems and such to communicate to Ski Area Lifts and Point-to-Point Short Hauld DSL devices.
Here are a few examples, realize these are APC, but many other vendors are in this space now:
Metered-by-Outlet Rack PDU - Product Information
Switched Rack PDU - Product Information
Here is TrippLite's version as well:
These are a couple links to the products, basically these will allow you to Telnet/HTTPs into the PDU & power off/on individual power ports. I hope this helps you Jay.
Great, thank you.
My nimble is out of my reach now. (In DR) Is there a physical on off toggle switch that goes up and down in addition to the power button in the front?
If so as long as the switch is in the on position and the software has been sent a shutdown command, a simple power cycle of the outlet is all that I need to boot up the nimble? The nimble doesn't need a bios setting that says power up after power failure?
It would be like going up to the front of the nimble and pushing the power on button?
I would ask that you contact Nimble Support.
So you are saying that if I do a graceful shutdown, the only way to get the array to boot again is to cycle the power (provided the BIOS is set correctly)?
Ok, I didn't mean to confuse.
Im aware of all the IP based PDUs and what not to power cycle outlets. Im looking for one specific feature found in many network devices not in the Nimble.
1. I send a graceful shutdown command to the Nimble because we are having a scheduled power outage or for any other reason. (Another example is one time our DataCenter Air Condition broke)
2. Power comes back on or the AC was fixed and I am ready to now start the nimble.
3. How can I start the Nimble with out someone physically going to the Nimble Box and pressing the power button on the front.
Normally with other devices and servers I can ILO/Drac or do some other type of hands off logon to the device and press a virtual power on button for the device and it powers up remotely.
I cant do that with Nimble.
Kick-starter for an IP based button push? Think of a pencil hooked up to a spring connected to a remote PDU
Seriously though, with everything being remotely managed can I make a formal hardware request for future Nimble products?
I'm pretty sure the OS supports IPMI commands, though whether they're available and exposed for customers to use I can't say. Would be nice to have them included or available in future releases for just such a need.
I will put in a Request for Enhancement for the functionality you are requesting (Auto Power On of the array when power is established via BIOS configurations). Having worked with other vendors & been in your shoes as a SysAdmin/IT Director, I know the pain of managing systems remotely and having to wait for someone to physically turn on hardware (Or better having to drive in during a 3 foot snow storm to turn hardware on).
Just to be clear.
I am not looking for: (Auto Power On of the array when power is established via BIOS configurations)
I don't think this is a good idea. For example, say when the power on your UPS is unstable and is going on and off constantly for what ever reason. I wouldn't want the nimble to power on by itself when power is established and then have the nimble powered off during boot because the UPS bouncing up and down. That would kill the Nimble
What I am looking for is the ability to send a single power on command remotely when I am ready and I control. Just a virtual power button I push. Just like ILO/DRAC and other remote power on solutions.
I appreciate the clarification & I'll make sure to reference your request for ILO/DRAC functionality.
Sorry to resurrect such an ancient thread, but were WOL capabilities ever added to the CS250?
The reason I ask is that we have one in a remote location, and have just been informed that in a couple of weeks time the power will be cut for up to 12 hours overnight, and I have to assume our UPS' will give out before power is restored.
Everything else we can bring up remotely, but the Nimble appears to need a button push??
Reading this thread, is it true that if I power down all my hosts, but leave the Nimble running, when the UPS power eventually fails, when it is restored the Nimble will power up automatically, however if we shut it down completely (the correct thing to do), it will take a button-press to power it back on?
Seems a bit short-sighted not to have some sort of DRAC, iLO, WOL remote access?
You are correct. If you leave the Nimble Array powered on, when your UPS does finally run out, the Nimble Array will go dark (like pulling the power cords). When power is restored, the Nimble Array will then power back on without the need for a button push.
If you issue the 'halt' command or shutdown the array from the GUI, you will need to push the power button on the front of the Array.
Do you (or anyone) consider it safe to let the Nimble Array go dark when the UPS power runs out, or would you consider that risky?
I have the same question.
Has WOL or "iLO/DRAC" functions been added?
I am sure they could do WOL but question would be to which NIC port on which controller and if only 1 controller could it power on the second controller. During a clean power up?
If like ILO. there would need to be an out of band management card in unit, executing the power on. to both controllers @ the same time..
Just look @ the achitecture of the units. they are PC Intel Xeon based. computer with cross connects @ some level.
