  While putting the host in maintenance mode, I'm stuck at 2%

  With the message at 2% it get stuck below.

  "Waiting for machines virtual to be powered off or migrated. In a DRS cluster, see the page of defects on the tab of the DRS for troubleshooting. "

  When you put a host in Maintenance Mode, the virtual machine will be generally migrated to other hosts automatically by the Drs there are reasons why it would not work.

  Some of them are:

  • You do not have DRS licensed (only included in Enterprise and Enterprise Plus)
  • DRS is set to manual
  • You have the DRS, but the virtual machine connected local resources (such as the CD-ROM player,...)
  • You have the DRS, but there are no hosts available because of rules configured to affinity/Anti-Affinity
  • Not available on other host resources

  In both cases, you will have to solve the issue and migrate virtual machines to other hosts or stop the virtual machines. As soon as he has no more power on virtual machines on the host, it will enter into Maintenance Mode.

• VMotion after putting the host in maintenance mode

  I would like a way to put a server esx in maintenance mode and let it automatically script vmotion guests to other hosts. It's about default behavior in the GUI, but when I use set-vmhost-maintaining state in the powercli, the host will just wait until all the vm is turned of / of are migrated manually, before going to interview.

  An easy way to achieve this, without loop through all the vm on the host?

  Thank you

  Hello

  Current behavior of the whole-VMHost (in vSphere PowerCLI 4.0) is an error report if it are turned off.

  Game-VMHost myHost-Maintenance State

  Game-VMHost: 15.10.2009?. 17:47:22 set-VMHost BAECC66D-9238-4AA3-829 a-76

  0E195F7DF1 there are one or more powered on virtual machines on the host myHost. The host is in maintenance mode once all virtual machines are turned off.

  On line: 1 char: 11

  ++ Set-VMHost< -vmhost="" myhost ="" -state="">

  However you can use the HostSystem.EnterMaintenanceMode method as a workaround.

  $h = Get-VMHost myHost | Get-View -Property Name
  $task = $h.EnterMaintenanceMode_Task(-1, $true)
  $task | Get-ViObjectByVIView | Wait-Task
  

  Here's what the SDK documentation says on the migration of virtual machines

  Operation not directly initiate evacuation operations or power off virtual machines. However, if the host is part of an active cluster with VMware DRS, DRS provides recommendations for migration to evacuate VMS under tension. If the DRS is in fully automatic mode, they are automatically on demand. If the host is part of a cluster and the task is published by VirtualCenter with evacuatePoweredOffVms set to true, the task will not succeed unless all the virtual computers turned off are reregistered to other hosts. If VMware DRS is enabled, VC will evacuate VMS power off automatically. The task is cancelable.

  Kind regards

• VMotion fails for a few VM when host in maintenance mode

  When I was performing updates ESX host today, after putting one of my hosts in maintenance mode, I have noticed after a few minutes my migration had ceased.  In one case he required a restart of the virtual machine, in another case, I found that one of the virtual machine is always connected to the host CD ROM

  My concern is that it appeared that, once one or VM have been unable to vmotion, all subsequent vmotions have ceased. Is this normal?  Is there a document that identifies conditions that will prevent the Vmotions?

  Do a manual VMotion on those virtual machines to see the error.

  Generally can be a simple a local CD or ISO local...

• The host in safe mode

  Can someone tell me how to start VMware Workstation if the host in safe mode. the host is 32-bit Vista and VMware Workstation running Windows XP Pro Sp3

  Sure, why not?  For your home, your virtual machines are simply sets of files.  Save them, copy off, etc..

• need to get the time host was put in the annotation and maintenance mode

  Hi - it is possible to get the time that a host has been in maintenance mode and also seize any annotation is attached to the ESX host in VC?

  Thank you

  ~ Sai

  Also, by using "get-vmhost" twice is redundant since you have channeled from get-vmhost: "E = { get-vmhost $_ |}". Get-vievent ".

  However, your order will be to return the entire event object and look like:

  Name                                    Event

  ----                                    -----

  host {VMware.Vim.EnteredMaintenanceModeEv...

  You can try below instead:

  Get-VMHost |? {$_. ConnectionState-match 'Maintenance'} | Select Name, @{N = 'Time put in MaintMode'; E={($_ | Get-VIEvent |? {$_. FullFormattedMessage-like"* entered maintenance mode *"} (). " Createduserid}}

  But it can still recover multiple events, so a way to get only the last event and time is below:

  Get-VMHost |? {$_. ConnectionState-match 'Maintenance'} | Select Name, @{N = 'Time put in MaintMode'; E={($_ | Get-VIEvent |? {$_. {"FullFormattedMessage-like" * entered maintenance mode * "} | toplayer-last 1). Createduserid}}

• Move the gun off-host for maintenance

  I'll take a host down for maintenance, I have a replica on this host.   I need to move that line off the coast of the host?  If so, how?  It looks like the power off replica can not be moved.

  I guess only the file replica on the data store is referenced and I can be propelled out of the host of some sort and have no impact for users.  This hypothesis is correct?  Or I have to move the replica some how?

  You can move this replica by choosing the move off the power option invited when placing the host in maintenance mode.

• Evacuation of the virtual machines before maintenance mode

  When ESX is placed in maintenance mode - it should give you a vmotion option functioning of the virtual machines on the other hosts in the same cluster?  Or it only move down vms to other hosts?

  Thank you

  DRS is your friend here, ensuring that VMS are evacuated.

  If you are unable to vMotion VMs manually from the host, the y is unable to escape during operations in Maintenance mode. The host will therefore go not in maintenance mode before having been involved and sort the vMotion.

  Most often, CD-ROM etc are involved here, but validation of vMotion also includes such things as the availability of resources and port groups (that is, if a group of ports corresponding to that used by the virtual machine is not available on another host in the cluster that has the resources available, the vMotion will not pass validfation and the virtual machine will remain on the host of 'Maintenance Mode').

• Where to find the info maintenance mode in newspapers?

  All - I did a few majro interview this weekend that took place longer than expected.  Is there a log somewhere that would list the time that I put the hosts in maintenance mode?  I want to see how long it took to do to migrate my guests from one host to another.  I looked at my logs of VC and it seems that they all turned.

  ESC 3.5 U4 and VC 2.5 U4.

• Put a host in maintenance - it will automatically move virtual machines?

  Dear all,

  We have a cluster with 4 guests and we would now like to upgrade each 5.50 to 6.0 ESXi ESXi host. I understand that we need to put the host in maintenance mode. He will automatically move virtual machines to other hosts? I read DRS is necessary. I see that our guests are permitted for Vmotion and HA. We have standard Vsphere license.

  This means in our case, I would need to move manually first of all VMs before the host can go into maintenance mode? In the case where the Vsphere will make work, the virtual machines automatically distributing to 3 other hosts according to the resources available?

  Thank you

  Edy

  This means in our case, I would need to move manually first of all VMs before the host can go into maintenance mode?

  Yes, since the Standard edition doesn't include DRS, you must manually move virtual machines to other hosts.

  In the case where the Vsphere will make work, the virtual machines automatically distributing to 3 other hosts according to the resources available?

  Yes, this would be the case with the DRS in place.

• ESXi 5.0 maintenance mode

  Hello

  I was testing just esxi 5.0 on a dell server. What exactly does maintenance mode only when a host is placed in the corresponding mode?

  I just uninstall Dell OpenManage ServerAdmin VIB without placing the host in maintenance mode. I know this isn't the right way to the esxi host service but I was just test it and see what happens.

  Thank you

  Maint. mode prevents execution of this host of VMs.  It can be used to cause vCenter expel VMs for this host in a cluster HA or DRS so that you can work safely on this host.

• Update ESXi with VCenter VM on the host?

  I am trying to upgrade my host ESXi 4.1 4.1 Update 1, but the VCenter VM lies on this matter.  I have to do to make sure that the DB VCenter is not corrupt, or can I just stop, put the host in maintenance mode and using esxupdate?

  With shared storage, you can:

  • Make sure that you have not activated the mode of locking for guests
  • Stop the vCenter Server VM
  • connection to the host on which it is running and remove it from the inventory
  • connect to the host of the second, browse the data store and add it to the inventory
  • vCenter Server on the second host market

  Generally, you will use Update Manager (if you are using vCenter Server), but in cases where this is not possible, you can also use vihostupdate.

• question of maintenance mode

  I need to close my clusters 2 and VM running under them.  I put the host in Maintenance mode before closing them? I think to close all VM and then stop host.  any advice would be appreciated.

  If I disable the HA and then shut down the virtual machine, then how it will work when I put them online after an upgrade? These virtual machines will register on a single host when they were closed? thnx

  Yes, the virtual machine if they are turned off on your host, once the upgrade has completed, put simply all VM under tension and then reactivate HA in the cluster.

• Will be the virtual machine starts on another host (during the blackout) if he can't switch to Maintenance Mode?

  Hello

  We use a cluster with 2 5.1 ESXi hosts.  When attempting to place an ESXi host in Maintenance mode, he failed and said "not enough resources to satisfy configured level of failover for HA.

  We would like to know, just in case where one of these ESXi hosts failed, VMs will be start on another ESXi host (at least some) or all of them will be down (i.e. None of them start)?  If no virtual machine will be migrated, we will change our level of failover for HA.

  Thank you

  This occurs when you enable admission control on your HA cluster. When the failure of the host occurs and you have Admission control is enabled, it will let all market on the other host machines because it violates the constraints of availability.

  If you turn this off all VM is switched even if you do not have enough resources to accommodate all the s VM on a single host. On a long term, I would say that you have sufficient resources to allow this to happen. But for now, you can turn it off and try.
