• Maintenance mode migrates is most Virtual Machines running

  Anyone know why they kidnapped the VMotion feature automatically running and stop virtual machines on a host that is put in Maintenance Mode?  Since a recent installation of vSphere 4, I noticed a host in maintenance mode will migrate VMs that are stopped, but not running VMs.  I was wondering if anyone else has noticed this and maybe knows why?

  Thank you!

  I had this same problem with vSphere 4 until I finally realized I had to change the settings of CAC on the cluster.

  Please graphics to order the 2 below. I think you'll see the error message then the resolution in the second chart.

  If this action was resolved for you, please reward me with the correct answer.

  Thank you!

• lyingWhen application of a fix via ADOPTION, he failed with the AutoPatch error: you must be in Maintenance Mode to apply the patches.

  Everything by applying the patch Patch 18345006 as explained in Doc 1981206.1 , in the phase to apply it, I get the error

  AutoPatch error:

  You must be in Maintenance Mode to apply the patches.

  You can use the AD Administration utility to set the Maintenance Mode.

  I'm on Oracle EBS 12.2.4, Windows 2008 R2 x 64, 2 appl_tops not shared and the error occurs on the primart node.

  How I applied the patch

  source, run fs

  adoption phase = apply patches = 18345006 = no allnodes

  The issue was that my tns ifile was entered incorrectly for _PATCH entered tns. After having corrected the phase to APPLY fine.

  Apparently, the maintenance mode error is just a smoke screen

• Rules of affinity and maintenance mode

  I have a virtual machine with a virtual machine to host mandatory "must" affinity rule that it must run on a single server ESXi 5.5.

  I'm going to try to put this ESXi host in maintenance mode.

  If the virtual machine with the affinity to the broad rule, but leave that it registered to the same host ESXi 5.5 power I, I then be able to put the ESXi host in maintenance mode?

  Or do I actually move the engine off the virtual computer to another host and enter it here to the ESXi host be allowed to enter maintenance mode?

  Thank you!

  According to my understanding affinity rule anti affinities and rules run on virtual machines running. So either hospitality you can keep the virtual machine.

• vCO Bug - Maintenance mode?

  Hello

  I find that the workflow item 'Exit Maintenance Mode' does not work. If I place a host in maintenance mode (clearly working, vsphere client) and then try to run the workflow, he does not see the host as being in maintenance mode.

  I tried to write my own scriptable task:

  var ConnectionState = host.runtime.inMaintenanceMode;
  
  
  System.log(ConnectionState);
  
  
  

  [09:45:14.393 2014-09-02] [I] false

  The result of this is always False.

  Any ideas?

  This may be caused by the use of the service of the inventory. Try to disable it by adding the following line to the file vmo.properties vCO

  com VMware.o11n.vim.useInventoryService = false

• close procedure, necessary maintenance mode?

  Hello

  We add the ram for the blades of our production. We will stop the running virtual machines.

  I don't remember if I need to place the ESX host in maintenance mode before power off?

  can anyone confirm?

  It would be a good idea to set mode maintence first then the front blade power off memory upgrade

  VCenter otherwise go see that a unexecpted by saying stop and a virtual machine could land on the blade during power off if you have some DRS will.

• How to upgrade vcenter host when the host needs to be in maintenance mode

  Hi, I have a host 5.5 with 3 VMs (2 production servers and 1 Server vcenter). Now I see for updating the host using vcenter Update Manager documentation is quite simple. The thing I don't understand until you can fix, the esx host must be in maintenance mode, which means no VMs, including the vcenter server, which is the only way you can do a right click on the host and choose restore. Now how can I fix if the server is in maintenance mode and my vcenter server is down?

  I have the vsphere client installed on my laptop, version 5.5, but him, I did not have the remediation option. How can I put my 5.5 esxi host?

  Thank you

  With only one host in place and vCenter Server as a virtual machine running on this host, you cannot use Update Manager. Your options are either interactively update the host using a CD or update patch / the host from the command line using esxcli.

• VCops cannot determine if a vSphere host is in maintenance mode?

  VCops 5.7.0 running.  Try to compare performance before and after a certain date.  However, the current environment has 3 hosts who are in maintenance mode.   vCops does not have the MM into account when calculating the host how many are in the cluster and how machines virtual hosts.  This lost data when you try to compare to the previous period.

  This has been resolved in later versions?  No work around?

  Thank you

  It is has not been implemented in the versions available (up to 5.7.2)

• Maintenance mode that is required to scan?

  Our best practices has always been to put the hosts in maintenance first mode, and then analyze the updates with the Update Manager. We seek to implement scheduled scans, and the only thing stopping us is our practice of the mode of maintenance in advance. Is this necessary? Or are we able to scan hosts for production with active virtual machines safely?

  Yes, you can scan the hosts while they have running VMs. Maintenance mode is not necessary for this.

• Can you change what core is vmotion ports without going into maintenance mode?

  If you have a host running, with a vswitch standard, can you change what port kernel manages vMotion without putting it in maintenance mode?

  What is happening is that we have a number of blades, all running vSphere 5.1.  Each host has a unique vSwitch with multiple groups of ports and a dedicated port vmkernal for vmotion and another dedicated one for the management network.  We use a VLan to separate the vmotion network.

  Our networking group will do a reconfiguration that will change the VLan dedicated for the vmotion.  What I would like to check the vmotion network management for each host, clear the check box on the Group of ports "vmotion".  The new vmotion VLAN is set up by the network, and then I go back and make the changes on each slide so that the "vmotion" is now enabled and remove the functions of vmotion for the management port.

  I know that it is not recommended to run the vmotion traffic on the management port network, but it will only be short term (probably a week or two).  My biggest concern is whether I can make changes 'live' without affecting the machines running.

  In a note related, if a host loses contact with other hosts on the network vmotion, which will pose a problem (in addition to not being able to vmotion)?  Will be the loss of connectivity on only the port of vmotion cause any kind of response of isolation, failover, etc.. ?

  Basically, you can modify most of the settings of network - including vMotion - without affecting the virtual machine. When you say that they reconfigure VLANS, do you know how long it will take and if the VLAN current will be available during this time? In this case, you would not have to implement no work around, but just update the VLAN groups of vMotion ESXi host ports.

  André

  PS: about your question "will be the loss of connectivity on only the port of vmotion cause any kind of response of isolation, failover, etc..?

  No, it's the management network that is used for HA, so everything what he let go is vMotion/DRS.

• Questions about maintenance mode

  I have some curious (probably dumb) questions on the service mode (esxi worm 51).

  • What is exactly?
  • What happens if you run the patch similar to ' esxcli software vib /vmfs/volumes/datastore/patch_zipfile.zip d install "without putting it in maintenance mode?
  • What happens if you put maintainece mode, install the patch, and then out of maintenance mode before restart? The reason behind this is so that the virtual machines will autostart.

  These are just curious of rhetorical questions.

  Thank you!

  Arch

  All the maintenance mode has really is sure no VMs are running. In an environment of DRS, VM will migrate automatically away, basically saying maintenance mode "do not put a machine virtual here, is about to have some work." Without the DRS maintenance mode will fail and advise you to move the virtual machines yourself.

  Some patches require no maintenance mode and install fine. Those who demand the it will error and refused to apply without maintenance mode.

  In the third scenario, the machines will be autostart

• Add or remove a host NOT in a DRS Cluster maintenance mode

  Is there a reason why add a host in an active DRS cluster that has say 20 virtual machines running on it would cause problems?  I understand a host must be in maintenance mode when adding or remvoing in a DRS cluster, but this can be done by disconnect/remove/add the host to the cluster.  Is there a technical reason why we should not do?  It disrupts DRS or HA?

  You'll be fine.  Best practice dictates in and out of a cluster in maintenance mode, but...

• In Maintenance Mode via command line?

  I have compilation scripts that can rebuild a host on the network, and I was wondering if there is no way to set the host to be in service at the end of my script mode.

  The reason for this when I add to the cluster using the virtual Center I would ike host to be already in maintenace mode so I can manually run the Update Manager to make sure that it is at the level of the appropriate fix.  I would then HA etc. when out of maintenance mode.

  I know that it is a function of the VC, but as it's a freshly built box I don't know there must be a config I can change on the host to enter maintenace mode.

  Any ideas gratefully received.

  Thanks in advance

  "vmware-vim-cmd/hostsvc/maintenance_mode_enter" and 'vim-vmware-cmd/hostsvc/maintenance_mode_exit' he will be in and out of maintenance mode...

• Disable HA or use the Maintenance Mode when the upgrade of the network switches

  Hello

  We expect the upgrade to our network switches. In the case where the hosts loose network connection I want to avoid having HA suddenly and guests try to run current virtual machines. What is best practices for cluster HA-activated in case guests loose network connection?

  Disable HA or put all hosts in maintenance mode? Or is there another suggestion?

  Vickers

  If you are using vSphere 4 there is option to disable HA response to failure without disabling agents HA HA. This option has been added specifically for when you know you're going to do the maintenance of the network and that you do not want HA answer when the management network is down. It is much faster to do that that in order to completely disable the HA or put all hosts in maintenance mode.

• Question on the Maintenance Mode

  When you select "Shutdown" or "Reboot" in the vClient, I get the following message:

  "The host is not in maintenance mode. Are you sure that you want to, stop, or restart >? »

  I looked in the manual and it does not need the ESXi host in maintenance mode before you shut down or restart.

  I would like to confirm that there is no harm to execute an action when NOT in maintenance mode.

  Thank you

  This is more than a warning.  If you have guests running on your host computer, they will both go down.  But if you have no guests, no harm.
