Hyper-V Automatic Start-Up

Hi Everyone,
Got a call this morning to say that after a power outage last night users were unable to access some critical services.
These critical services were located on Virtual Machines which are hosted on a 2012 R2 server.
Configuration is set to automatically start the Virtual Machines; one immediately, another after 60 seconds, and another after 120 seconds.
For some reason, none of the virtual machines started automatically .. and so begins the early wake up call.
I've had a look at the logs and can't really find anything which points to a failure to start a machine, the only thing I've found is errors in relation to the Hyper-V Replication service due to the replication server currently being down (that's the next
job, just hasn't come back up since outage).
Servers started perfectly when starting manually.
Any idea's would be greatly appreciated.
Cheers

overall there is no automatic failover in Hyper-V
Of course there is. It's enabled by Failover Clustering. This is a totally separate technology from Hyper-V Replica.
There is no automatic start up in Hyper-V Replica because it is not designed to detect a split-brain condition where the same virtual machine is running in multiple locations simultaneously. The replica site has no way to know why it can't reach the primary
system anymore. It might just be because someone unplugged a network cable. If the primary's virtual machines are still running and the replica decides to spin up its copies, you will have many troubles.

How to configure automatic start option of the Hyper-V role (Windows 2012 R2)

Hi,
If there a way to configure the automatic start up option of each Virtual Machine?
I know that you can't use the VMM settings to setup the Automatic Start action, and the Cluster Hyper-V setting only specify the "shutdown" action.
How can I make sure that after a an event like a power recovery affecting all my node that all my Hyper-V role will be started?Thank

Hi,
You can set the guest vm start up after your host computer start up, if you want to specific the guest vm start up order please refer the following related article:

VMM 2012: How to Configure Automatic Start and Stop Actions for a Virtual Machine?

Does somebody know how to confgure Automatic Start and Stop Actions for a Virtual Machine in VMM 2012?
I miss that option.

Automatic Start or Automatic Restart actions are available for virtual machines running on a Hyper-V cluster from within Virtual Machine Manager.
From within Virtual Machine Manager, bring up the Virtual Machine's properties:
Click "Hardware Configuration"
Click "Availability"
Click "High", "Medium", or "Low" to enable automatic start/restart or
Click "Do not restart automatically" to disable automatic start/restart
Screenshot from VMM 2012 for a VM running in a Server 2012 R2 Hyper-V cluster:
VMs running on a cluster have to be marked "Highly Available" and logically, Microsoft assumes that you'll want these VMs to be running all the time when this setting is selected. If the cluster fails or needs to be restarted, you can set the priority
by which a VM restarts, or you can set the VM to not restart at all when cluster services are restored by using the settings above.

Hypev "automatic start action" not retained after live motion

Hi,
We have a hyper-v cluster of 2 windows 2008 R2SP1 nodes.
We found that the settings we made in the VMs "automatic start action" were reset to "none" after migration between the nodes .
We need to have it maintaned
thanks
Stefano

Hi ,
I think there may be something unclear in my previous email. Ok, I will detail it.
If you make a virtual machine high available, the Automatic Start Action will not work after you perform a live migration. Which means the following setting will not be "failovered" to another host.
You should set this via the Cluster Manager by the following setting:
This is what I said:
If you change the configuration of a virtual machine, we recommend that you use the Failover Cluster Manager snap-in to access the virtual machine settings. When you do this, the cluster is updated automatically with the configuration changes. However, if
you make changes to the virtual machine settings from the Hyper-V Manager snap-in, you must update the cluster manually after you make the changes. If the configuration is not refreshed after networking or storage changes are made, a subsequent failover may
not succeed or may succeed but result in the virtual machine being configured incorrectly.
Thanks. Feel free to let me know if anything is unclear.

Hi Aaron ,
yes I think there's a misunderstanding about the question .
When you say
"If you make a virtual machine high available, the Automatic Start Action will not work after you perform a live migration. Which means the following setting will not be "failovered" to another host."
you mean that it is supposed to work this way ?
I mean , If you make a VM HA with clustering is it an accepted behaviour that the setting of " automatic start action " ( not the stop action you posted the picture of ) is not maintaned after a live migration even if such setting is made through the failover
cluster manager ?
If you are telling me that this is what it is supposed to work I don't agree , because I wish I can have a way to set a priority in VM startup in the case of complete shutdown/reboot .
Working with vsphere as well this is possible and I thought it was the same with Hyper-v
To solve this problem I had to create a group policy's startup script for the cluster nodes in which I start the VM in the correct order with some timeout .
Thanks
Stefano Colombo

Automatic Start Actions for a Virtual Machine

Hi ,
We configure some VMs on a cluster
the default setting of automatic Start action is set to Nothing
when the cluster is down of hyper-v service is stopped , once the problem is solved , All VM will be run as it was running before the problem happened
So What is different between the following options of automatic Start action
Nothing
Automatically start if it was running when the service is stopped
And do you know why it is st for standalone Host not for the cluster as per this thread

FYI - Automatic Start Actions in the settings of a VM are different once the VM is HA under Clustering. Since the job of Clustering and HA is to keep that VM running.
If you look here:
http://technet.microsoft.com/en-us/library/cc732181(v=WS.10).aspx#BKMK_Machine
You find this:
Automatic actions let you automatically manage the state of the virtual machine when the Hyper-V Virtual Machine Management service starts or stops. However, when you make a virtual machine highly available, the management of virtual machine state should
be controlled through the Cluster service. In this step, you reconfigure the automatic start action for the virtual machine.

How can i disable imessage from automatically starting up when i turn on macbook air?

how can i disable imessage from automatically starting up when i turn on macbook air? i dont know my imessages to pop up on my laptop when it turns on. But i dont want to disable imessage totally on my macbook.

Welcome to the Apple Support Communities
First of all, check that Messages is closed when you turn off your MacBook. This is so important because, by default, OS X will reopen all opened apps the next time you start your Mac.
Apart from that, when you go to  > Shut Down, or  > Restart, in the window you see to restart or turn off your MacBook, unmark "Reopen windows when logging back in". This will avoid that your Mac opens all opened apps the next time you start the MacBook, so Messages won't start automatically at startup

SAP system doesn't automatically start after restart (but manual start ok)

Hi,
We've got a new production line of SAP EP 7.0 systems, which have CI on HP-UX and DIs on windows. The version is NW2004s SPS09.
What we see is that after a restart of the windows servers (usually because of windows patching), the SAP system doesn't automatically start up. It doesn't start up if I restart the SAP<SID>_<instance> service either.
However, I've got no problem starting the system with the MMC.
Any idea what I am missing here? is it as simple as a profile parameter ?
As far as I can see the profile used seem ok.
After a restart of the windows server the following files have log entries in the c:\usr\sap\<SID>\J<instance>\work folder
sapstartsrv.log
trc file: "sapstartsrv.log", trc level: 0, release: "700"
Fri Nov 17 15:51:26 2006

(at the same time)
Failed to update service environment from user (STATOIL-NET\<sid>adm) environment. [ntservmgr.cpp 201]
(note that this doesn't happen for all systems which have this problem, for other there is no entry like this)
I see no failed login attemps in the security event log, but see the that a login is performed for SAPService<SID>.
Since it also fails to automatically startup when I restart the service, I am able to use filemon to see what happens at a file level. Here I see that it can access the shared file system without any problems, and can read the profile and everything.
MOM is running on the server and gets some Access denied errors since it doesn't have access to the shared file system, but I don't think that matters.
Cheers

hi we are using sap bw 3.5 . database is oracle 9i
i applied a kernel patch and when i tried to start the services . there was no problem with the oracle services and saposcol but the service sap<sid>_nr did not start .
when i went to check the error in work folder ..
it say " SapSSLinit failed => https support disabled .
then i tried to start sap from cmd pmt . din`t work .
is there a way to statrt this ...
thanks alot.

When I insert an audio CD into my iMac, it automatically starts playing

When I insert an audio CD into my iMac, it automatically starts playing, and I can't figure out why, nor how to stop this behavior. When I click in the upper right corner of my screen where it says "Finder", it shows the Finder as the only application running, and yet SOMETHING must be causing the CD to play. If it is an Extension that is being loaded, is it possible to terminate the Extensions one by one without restarting the computer to see which one is playing the CD?
Is the OS9.1 operating system supposed to automatically play audio CD's when they are inserted into the iMac? Or could it be an Extension that is doing it?And if so, why is no means provided to actually CONTROL the playing of the CD (such as a control panel with PLAY, STOP, SKIP, etc. buttons)?
On a PC, I can press Control/Alt/Delete to bring up the "Task List" that will show me ALL applications and processes currently running, and then terminate apps and processes one by one without having to restart the computer to see which one is playing the CD. Is there an equivalent way to display this information on an iMac that will show me which application or process or extension might be causing the audio CD to play, and allow me to terminate them one by one without restarting the computer until I can see which one is the "problem"?
Jerry

Hi, Jerry -
Welcome to Apple's Discussions.
Finder uses QuickTime in the background to do that, hence no specific app is shown in the Application menu (the far right item in the main menu bar) in addition to Finder.
To unset automatic playing of CDs (and DVDs) -
Open the QuickTime Settings control panel (Apple menu > Control Panels > QuickTime Settings).
In that control panel, select AutoPlay from the pulldown menu in the control panel. Uncheck both the items shown in the new window. Close the control panel.
No restart should be needed in order to make the change effective.
Doing this will also guard against the (now ancient) AutoPlay virus, which could still be lurking somewhere on the net.

In Lion, running on an I MAC, (late 2006), how can I stop certain programs (iTunes, Word) from automatically starting up when I start the computer?

Any application that is open when you shut down will re-open when you restart unless you deselect this when shutting down/restarting:
Also check System Preferences>Users & Groups>Login items tab and make sure there's nothing listed there that you don't want launched.

How do I prevent Firefox from automatically starting when I boot-up my Mac in the morning?

Whenever I boot up my Mac in the morning Firefox automatically starts and displays my home page. I would only like to see the desk top with no applications running. I am running OSX 10.4.11 on my laptop.
== Started possibly a few weeks ago.

Hmm.. Okay I've done a bit more digging and tried the following two things before the last restart.. Not sure which one actually worked but give these a shot (one at a time) and let us know which is the ''actual'' solution! :)
1. Open Safari -> Preferences -> General
- change "Default Web Browser" to Safari
- Close all applications
- Relaunch Safari and change default browser back to Firefox.
2. Remove the check from "Reopen windows when logging in" in the logout dialog and logout of the computer..
I suspect step 2 is actually the proper solution, but I did both so, hopefully one of them works for everyone else!

How can I keep this from automatically starting up??

Finally sorted the same problem on both my pcs. If you are a member of Facebook, then the problem likely is because of that.What I did to spot Spotify automatically starting up. 1. Log into Facebook, and then into Account.2. Go to Account Settings (on Facebook).3. From there go to Apps (on left side of screen).4. Find Spotify in the list of Apps that shows up and press the "x" button to the right of "Edit".5. Log out of Facebook.6. Log out of your PC.7. Restart the PC.8. Spotify will still appear asking you to log in with Facebook or Spotify password.9. Log in to Spotify with your Facebook password.10. On Spotify - go to Edit (top left of Spotify screen).11. Scroll down to Preferences.12. Scroll ALL the way down to the bottom, and IF it says Log on Automatically, click the "Don't Open Automatically".13. Log out of Spotify.14. Log out of your PC.15. When you switch your pc on again - the problem hopefully, as in my case, was resolved. I have had this problem with other things starting automatically in the past, and it has always been because it is an "App" appearing in my Facebook list. Do the things listed above in that order and hopefully it will work. Hope this helps. Good luck.Steve.

How do I keep ITunes from automatically starting when I boot my PC?

Everytime I start my PC, my I tunes starts automatically. I close it an it automatically starts again 5-6 minutes later. It happens when my IPhone is not connected. The problem began immediately after I updated to the new IPhone iOS 5 software.

I appreciate the help attempt greatly, however, I do not have an Iphone, only an Ipod that I use with Itunes. Basically I have Itunes on my Windows PC, (NOT MAC) and it just has a mind of its own and opens randomly, whenever. I have scanned and searching the Itunes application for something to click off for automatically run, or something to that effect and I see nothing. There has to be a way to disable Itunes from running automatically. It has nothing to do with whether or not my ipod is attached.
