• Host profile in vSphere 6 - requirements of Maintenance Mode

  I was instructed to check the profiles of the vSphere host 6.  The main reason why we don't use them in our environment v5.5 is because when you apply the profile of the host a host to perform a restoration, regardless of change in a significant way, there must be a maintenance of the host mode.  This poses an administrative challenge in my environment.

  So, I have been instructed to read that vSphere 6 had updated Host Profiles to demand maintenance mode only if required by the properties defined by the profile of specified host.  I think OK, now trivial changes like adding that a group of ports for a vSwitch will not require the host to be maintenance mode trying to "clean up" the host with a profile of the host that makes this type of low level change.  Unfortunately, I still get the error "host must be in before maintenance mode a host profile can be applied to him" whenever I try to apply a profile of the host to a host that is in non-compliance, no matter how tiny change.

  Everyone knows this?  I have something misconfigured?

  vSphere 6: updates to Host Profiles - VMware vSphere Blog - VMware Blogs

  OK I thought about it.  This new feature to Host Profiles fact exist, but it only exists in the Web Client vSphere.  The vSphere client c# don't has not been updated to behave this way, it always requires a host to be in the mode of maintenance for all corrections.

• vCentre Server 2.5 cannot connect to the VSphere host

  vCentre Server 2.5 with VMware 3.5 host work well, but it cannot connect to VSphere host.

  On step 4: ready to perform, there is an error message:

  Cannot access the specified host. He either does not close, the server software does not respond, or there is a network problem.

  In fact, I can see all the virtual machines on the host vSphere on phase II: summary of the host. So, I do not suspect the problems to which the error message mentioned above. I really want to know how vCentre 2.5 Server can work with vSphere well.

  Thank you!

  Hello

  vCenter Server 2.5 is not compatible with vSphere 4.x host. I think that VMware announced document compatibility matrix (between hypervisor host ESX and vCenter Server or other components). Please see below URL:

• Check if the esx host is in maintenance mode

  
  Hello

  I need to know if there is a api in java vi which can let us know if any of the esx host is currently in maintenance mode?

  I know there is a way to discover this through the same monitoring using event Manager, I need to know is an api live which can let us know if the esx host is in maintaince at that precise moment?

  Thank you and best regards,

  Rachid chollet.

  Hi rachid,.

  I guess that the following property is what you are looking for: HostSystem.runtime.inMaintenanceMode

  But watch out for the docs for the property when it reads it: it is not set during the entry phase of 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

  Maikel

  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.

• Cannot connect Vsphere host

  Until now, I was able to connect to the vsphere host, but some do not know how his disconnected, am able to ping the host vsphere 4.0, but when I try to connect client vsphere it gives me error attached.

  A cam in all of these question, is there any tobe need to service restarted on the console directly.

  I guess, you must restart the ssh (putty) session management services: -.

  service mgmt-vmware restart

  service vmware-vpxa restart

  Wait 2 - 3 minutes after that and try again.

• Cannot upgrade to ESXi 4 Update 1 via vSphere Host Update Utility 4.0

  Hello

  can someone tell me why I can't update ESXi 4.0.0 build 219382 to ESXi 4 Update 1 via vSphere Host Update Utility 4.0? The doesn´t utility see the update.

  The problem is, I can't download the update on http://downloads.VMware.com/d/info/datacenter_downloads/vmware_vsphere_4/4 because I always get the error

• Cannot add host ESXi 5.5 to vCenter for a routed network - cannot communicate with the specified host

  I was wondering if anyone has come across this problem before, who could give advice how to fix them:

  Host of pre-production UCS ESXi migration of a Production vCenter on another network (routing in place)

  Can ping both directions successfully - from vCenter Prod to the host of the pre-production

  no firewall between the two.

  902 port is open on the host

  Host connects to the pre-production vCenter on the subnet even fine

  VCenter production can add different hosts on the same network end

  Even with the various guests of ESXi UCS.

  ESXi host was completely disconnected and removed from vCenter inherited before attempting to add. No dvswitch physical or virtual.

  Then try and add, enter the user name and password and get cannot communicate with the specified host.

  Thank you

  The solution to this. Used ESX host 5.5 3B (3248547) update that disables SSLv3. (Ref: VMware ESXi 5.5 updated Notes version 3B) one of the consequences of this is that older versions of vCenter (such as trying to move the host) can not add/connect host.

  Enable SSLv3 to spend (port 443) on the resolved host (virtuallyPeculiar: connection A ESXi 5.5 U3b host to vCenter with a lower Version A.)

  Note: should not enable SSLv3 to Port 902.

• vMotion fails at 9% - Source host cannot connect to the destination host

  Hello

  I wonder if someone could shine any light on why vmotion fails to occur between an ESXi host who has just been restarted, in order to test HA. I have the following configuration:

  3 x ESXi5 DL360 G7s with two 4-way NIC

  VSphere Vcenter 5

  1 x cluster configured for DRS HA

  2 x Procurve 2910 - 24G

  The switches are not connected to each other.

  Both switches are configured as such:

  

  All ports are not marked. NO PLEASE, no routing

  Each host vMotion vSwitch is connected to two switches by 1 x 1 GB nic

  I configured a vswitch on each host of vMotion. There are two ports vmkernel with two IPS on the same subnet. There are two vmnic attached to the vSwitch. On each port, a Vmic is configured to be active while the other is unused. I enabled frames on the vSwitch and 2910 switches. A VLAN has been configured on the two predisposees 2910 for vmotion with frames and defined traffic on "no label". I can successfully vmkping all the ip s vmotion on all ESXi hosts. However, when I test HA by stopping an ESXi host, when I restart the ESXi host I am unable to vmotion in that ESXi host. When I test vmkping I find that the host rebooted can only vmkping itself and no other host can vmkping it. Vmotion attempt fails on 9% and errors with the source host cannot connect to the destination host. If I restart the two switches of 2910 I can then perform a vMotion and the vmkping is a success.

  Help, please?

  Thank you

  I have since read up on the various load balancing options and find that your method is preferable during the method of "ip hash.

  I'll make the change to "port based" and link the two switches

  Hello Simon, I think it's a good option to do, since the hash IP load balancing is a bit special and really requires both interfaces to connect to the same physical switch, which must also have a specific configuration. If you like the results after the new changes.
