• Update Server VC and 5.5 ESXi hosts to update 3 b (Build 3248547)

  I'm in vCenter Server 5.5 and 5.5 ESXi hosts.  Both are updated 3A, patched to version 201510001, which is the build 3116895.  I plan the upgrade of update 3 b (Build 3248547) and I'm a little confused on the question of SSLv3.

  I wonder if this point below ESXi55 U3b & VC 55U3b Known Issues applies to my config:

  ESXi does not automatically added to the inventory of the vCenter servers
  If you install an earlier version of vCenter Server and vSphere Update Manager for ESXi 5.5 updated 3B, then after the task of sanitation, ESXi does not automatically added to the VC inventory. Remediation process never gets done and ESXi State of connection in the VC inventory is presented as disconnected. Solution: When you restart ESXi after reorganization process is started, enable SSLv3 on ESXi (which is disabled by default). This will ensure that ESXi is added to the VC inventory automatically in minutes and sanitation as completed.

  If I'm reading things correctly, upgrade to vCenter Server to 3 b first and then upgrade the ESXi hosts, will avoid lost communication problems.  Can anyone confirm?

  It should be good if you update vCenter first.

  The problem is that pre - U3b vCenter 5.5 forces an SSLv3 connection when connecting to an ESXi host on port 443 (not the reverse). It does this, even if the host ESXi and vCenter SSL/TLS libraries actually support TLS 1.0 + since at least vSphere 4.0.

  So when you update one host to 5.5 U3b, the oldest vCenter again will try to force a connection SSLv3 that will fail, since SSLv3 has been disabled to the host. If you're updating vCenter, first of all, it will initiate a good TLS 1.0 + connection to more similar and updated hosts.

  Here is an explanation of the (pre - U3b) vCenter SSLv3 handshake behavior:

• Difference of ESXi hosts between analysis of updates and patches of scene

  Hello

  I have two ESXi hosts with round about 700 applicable patches.

  What is the difference between "stage Patches"und"search for updates"?

  Do I need maintenance mode for the scene fixes?

  Kind regards

  Roland

  

  Hello

  Scan for updates will scan the hosts against the basic lines of patch you have attached to them and to report on the status of this host against the base line, so, essentially, Scan for updates will tell you what patches and updates to your departure are absent from the host if the return "non-compliant" or "compliant" if all patches are already installed.  It can also return 'Unknown' or 'Inconsistent' according to the status of the host and other factors.

  Step will basically copy all files to update and patch that must be installed to the willing host for the conversion, which will be more actually to install patches.  Staging of updates to date does not make service, you don't need to put the host in maintenance mode, while the staging, the host must be in service during the reclamation mode.  You can trigger a reorganization without staging, but the benefit of the staging is, first of all, you will reduce the amount of time that your host is out of action because all patches and updates are already in place in anticipation of final approval, which means that the rehabilitation phase is much faster.

  I hope this helps.

• Create new vCenter and move the ESXi hosts

  Hello

  I created a new vCenter vCenter apparatus using ISO 6.

  The deployment went well and I have all the installation program. I would now like to move hosts our old vCenter to new ESXi.

  I was reading this article to start the moving process.

  When I try to disconnect the host I get the message below

  

  In the article in the link above it is written that it will not affect the State of the virtual machine running on the host.

  If I click on 'Yes' here, it will automatically put the host in maintenance mode?

  I prefer not to do it if I can avoid it because I don't want to have to evacuate all virtual machines running on the esxi host.

  Wouldn't it be better if I disabled it HA first? Then try to move hosts? Or I'm sure to sign-out and the subsequent removal?

  Thank you

  See you soon

  Hello

  You must put your server in maintenance as a first step mode, then unplug and remove the server. It will work.

  If it doesn't work, disable temporary HA and remove your host of the VC.

• When was the last time that 5.5 ESXi host not re-initialized and total times restarted last month.

  Hi team,

  We have more than 100 ESXi host in our environment, and we need to know when was the last time ESXi host rebooted and no times restarted last month. Please help me get the power cli script. Any help will be much appreciated. Thank you

  Thank you

  VMware tech

  OK, so the ESXi nodes were hard started (as if you pushed the power button).

  This is probably why the task for a planned restart does not turn upward.

  Do you see the ESXi nodes with the following script?

  It shows the events where the connection to a host has been lost.

  $start = (get-Date). AddDays(-7)

  Get-VIEvent - MaxSamples ([int]: MaxValue)-start $start |

  where {$_-is [VMware.Vim.HostConnectionLostEvent]} |

  Select CreatedTime,@{N='VMHost'; E={$_. $host.name}}

• Best practices for backup of vCenter device and ESXi hosts?

  Hello

  I have a new VMware environment based on 5.5 ESXi and vCenter Server Appliance. A few questions:

  • What is the best practice to perform the backup of the vCenter Server Appliance? I set up the camera with the embedded SQL Express database.
  • It's recommended to backup the ESXi host or is it easier to any re - install failure?

  Best regards
  ,

  Thor-Egil

  Hello

  You can use VMware VDP to backup your device of vCenter. It is included in essentials, standard, enterprise, and enterprise as well as licenses.

  I won't have backups of ESXi servers. Restore the backup would take more time that the deployment of a new ESXi.Only thing, you may want to consider is to enable logging remotely, so you can see why the hosts failed.

• go esxi hosts and virtual machines in one vCenter to another

  I built a new vCenter (Windows vCenter), I intend to move on ESXi hosts the old vCenter (Virtual appliance vCenter) to the new vCenter. I don't know if it's feasible, please notify my step is correct or not: 1) build a new vcenter 2) create a cluster with two esxi hosts first 3) Mount data (NetApp Filer Storage) to the new vCenter warehouses 4) add an empty host for the new vCenter VMs) 5 download then upload to the host in new vcenter

  Hi friend

  Its doable without any problem.

  Please follow the procedure below.

  1 build a new vCenter (your first step is correct)

  2 creating a cluster (because it is new vCenter there will not be any available host.) That is why cluster creation wizard will not get to add in the new cluster host). While initially empty cluster would be created.

  3. once the cluster is created, immediately do a right-click on the cluster and add your hosts one by one. Not necessary to cancel the registration and the VM. Virtual machines will automatically be added who were there on the data store available with all guests.

  Don't forget,

  1. we do not mount any store data in vCenter, we assemble the data store on the host.

  2. If you mount the new data store (which did not exist before), you can mount once the new hosts are added to the new cluster. (Your SAN admin help)

  3. If you want to move your virtual machines from data store before the newly added/mounted data store, please SVMotion these virtual machines (by right-clicking on the VM > migrate > data store > select the data store that is new)... Please follow the same procedure for all virtual machines.

  4. you don't need to add empty hosts to the new cluster, add just as soon as all guests without you register VMs. Later, you can migrate to other store of data according to the requirement. NO need to download or download the VM.

  5. Please make sure that your ESXi hosts will be compatible with the new vCenter. Old version of ESXi always compatible with the new version of vCenter. Just check if you have all valid licenses.

  Please let me know if you need any clarification

• VCM can collect and report on versions VIB ESXi hosts?

  Hello. I need to make sure that all of my guests have some version of the NetApp NFS (https://library.netapp.com/ecmdocs/ECMP1237939/html/html/GUID-735E5961-E3FB-4105-A8F8-37F6444B68BC.html) plugin, and I was hoping that VCM could pick this up, since VUM somehow cannot properly report on the question of whether or not this plugin is installed in each ESXi host.

  However, I can't find any good data on this in VCM, or documentation of VCM, or using a web search.

  Does anyone know?

  Not at this time.

• What is the interval of time between the virtual machine Linux and ESXi host synchronization?

  I have ESX5.0 with a centos6 installed on this linux virtual machine.

  After the installation of vmware for Linux virtual machine tools, I activated the time synchronization between the virtual machine linux and ESXi host through vmware-toolbox-cmd.

  I wonder what is the interval of time between the virtual machine linux and ESXi host synchronization? If I quickly time OS system, when the OS system time will sync back to the ESXi host?

  According to http://www.vmware.com/files/pdf/techpaper/Timekeeping-In-VirtualMachines.pdf:

  By default, the demon checks the guest only once per minute operating system clock.

  However, depending on whether the guest is behind or in front of the result is different. So, please read the section "periodic synchronization" (at least) in the document mentioned above.
