And if you extend Arnaud's sig link to:

You find another brand that is good. And I think you would like a 
PW5130L2500-XL2U. http://www.powerware.com/UPS/5130_UPS.asp

Arnaud,

Cool. Found the unit. Looks like they renamed it as I had a Pulsar EX 2200
and it is now the Pulsar M 2200.  The EX line only goes to 1500 now. Sent
the link to the reseller.

Thanks,
Doug

This part of MGE has not been droped, but sold to Eaton.
All the good things, including the NUT and more generally FLOSS support has
so gone to Eaton.

I would be really surprised if this couldn't be handled by VMWare.  
Briefly looking at some Googled pages, it seems that the host can  
signal the guests to shutdown and I assume it should also be possible  
to check if they have indeed done so. If that's the case, the host  
should signal the guests that they need to shutdown, wait until the  
last one has finished and proceed with shutting down itself. Scripting  
this should be pretty straightforward.

You should really ask on a VMWare mailinglist how to do this. We can  
help you shutdown your systems, but not any application (including  
VMWare) it may be running.

Usually, NUT expects system halt scripts to be dealing with this (with  
or without NUT running). Even for a system that is running 24/7, I  
would still want that. If they need to be brought down for  
maintenance, I don't want to have to think about what needs to be  
stopped, before it is safe to type 'halt -p' on the console.

[Nut-upsuser] Recommended UPS brand (OffTopic sort of)

[Douglas Parsons]

Hello,

I am looking for a compatible brand for nut. I currently have both APC and
MGE units in house. I liked the MGE units and had switched to them after
several bad experiences with the APC line. We ordered 13 APC Rack mount
units and the quality was horable. One blew up, two did not have the mount
holes threaded and several had considerable rust on them. With this I swore
off APC and found MGE. Then what happens? MGE purchases APC. Now I find that
most of the MGE models that I use are no longer available and so I am in the
market for a new brand of UPS.

I am looking for a 2200 VA rack mount in a 2U package. 120V in 120V out
single phase. What I would like is a product that is compatible with NUT and
supports serial communication. I know that some brand support more commands
than others.

I am not out to start a flame war on brands just get a list of one that
users have had good experiences with.

Really hate that MGE drop those models as I really like the quality and
design.

Oh well.

Thanks,

Doug

Thanks, Doug. I'm newly on VMWare Server 2, which has different tools
than the 1.x ones I'm familiar with. AFAIK the 1.x tools did not have
any sort of UPS or shutdown awareness capability; I'll need to check
whether that's true with 2.x.

Re: [Nut-upsuser] early shutdown of VMware VMs

[Douglas Parsons]

What version of VMWare are you running? This makes a difference as to your
choices.

Do you have the VMWare tools installed on the virtual machines?

With most versions you can have the host shut down the guest. Some versions
give more options than others.

As I understood from a previous thread there is no current means to trigger
at set battery levels for particular slaves. But you may be able to trigger
at a higher battery level so the host will start the guest shutdown and have
time to complete before you run out of battery.

If I mis speak here please correct me list. I an a novice on nut.

I think you have to ask on a VMware list how you configure the VMware
server to tell the VMware clients to shut down. Maybe just sending
ctrl+alt+delete is enough.

Or you could just use the notify command? Once ONBATT is reached,
then sleep for a 1 minute or more, and start the shutdown?
If you get a ONLINE then have the script check if all virtual machines
are running.

There might be a problem if the UPS has very little power left. So  
when you
get a LOWBATT execute a script that doesnt sleep but start the shutdown
now.

NOTIFYFLAG LOWBATT SYSLOG+WALL+EXEC
NOTIFYFLAG ONBATT SYSLOG+WALL+EXEC
NOTIFYFLAG ONLINE SYSLOG+EXEC

NOTIFYCMD /sbin/upsmail.sh

Then just include something that tells the virtual machines to shut  
down.
And install it on every vmware client unless you can instruct vmware to
shut the clients nicely down. Maybe tell vmware to sleep the machines
at ONBATT?

Because a clean shutdown of the VMs is more important than high uptime
for the VMs.

If both guest and host machines shut down at the same time, the host
might finish its shutdown before the guests have, leading to possible
filesystem corruption. I will gladly trade off some downtime of the VMs
to ensure clean shutdowns.
