5.1 ESXi host disconnects

• 5.5 ESXi hosts disconnection of the vCenter 5.5.0b

  Good evening.  I recently deployed some new hosts HP BL465c G8 running the HP OEM install ESXi 5.5 (not the one just released 02/18) and the two hosts have been disconnect from vCenter four times in the past week.  I can sometimes connect to the host via ILO and restart the vCenter agent, but more often without having to start the host hard.  In addition, one of the VMFS5 content of the data store disappeared and the virtual machines residing on this data store have declined because the hosts could not find the configuration of the virtual machine files. Strangely enough, the data store showed spaced used and I could see all the directories within the CLI, but not vCenter client or Web-based Client.  I have two tickets to windows with VMware from HP support team, but I wanted to know if someone had a similar problem.  I'm tempted to rebuild with the latest OEM installation or rebuild as 5.1 or 5.0 if version 5.5 is not fully cooked.  Thank you.

  The issue proved to be the OEM HP install and specifically the pilot v1.1.7 for HBA QMH2572 adapters that it contains.  We have rebuilt our 5.5 ESXi hosts using installation OEM HP published 02/14 (contains recommendations
  v1.1.12 pilot) and that solved the problem of stability.

• 5.1 ESXI host disconnects the vcenter, when reconnected SSL fingerprint has changed.

  I'm having a strange problem with only 1 of the 5 hosts connected to a cluster inside of vcenter. A host disconnects randomly vcenter.

  I right click on the host and select Connect. I get the default value to the warning that 'reconnect a host will replace any change in management of resources that have been made directly on the host... ". ». I select Yes.

  Then, I get an error

  The authenticity of the host SSL certificate is not verified. This option is to close.

  I am taken to the add hosts Wizard. where can I enter the password IP and root to add the host to the cluster.

  Now, I get a security alert:

  "Impossible to verify the authenticity of the host: the SHA1 of the certificate fingerprint is:

  The fingerprint shown is different every time I add this host.

  We have tried, replacing the network card management network is on, replace the cables, the port of the switch, that this machine is connected, completely reinstall esxi switch. Nothing has solved this problem.

  It turns out that the problem is that our agile took place of the intellectual property that it wasn't supposed to and it's a double that esxi host IP. Very strange behavior. But it's the solution.

• ESXi hosts disconnected/no response in Vcenter after upgrade (4.1 = > 5.5)

  Hello. I'm upgrading our current infra (hosts/Essential licensing Vcenter / 3 ESXi 4.1).  vCenter Server has been upgraded OK, so I started to esxi upgrade hosts one by one.

  Upgrade process is OK, but after the reboot, upgrade marked as "not responding" in vsphere client server. I could ping this host and connect via ssh.

  When you try to reconnect the client host, got a strange error "this edition of vCenter only supports 3 host (s) in the inventory. After 3-4 hours of nothing to host

  has begun to show ok. After upgrading a second host, the same situation. I don't understand, how to solve it without waiting for another 4 hours.

  Restart of host management agents does not help.

  I remember I have a similar situation in the past where the number of licenses does not update as expected, i.e. required some time. What helped was to restart the server vCenter Server in my case. Maybe worth a try!

• Retrieve message to ESXi host Summary tab "Configuration issues."

  Using VMware Perl SDK API, how to get the message of 'Problems of Configuration' tab summary ESXi host?

  For example, I have an ESXi host disconnected from the cluster, and in the summary for this host tab, there 'Problems of Configuration' message "disconnected from esxi_hostname in esx_clustername." "Reason: expired license."

  Is it possible to recover the message above through Perl SDK API? The host is already disconnected from the cluster, not sure if this is possible.

  Yes, you can take a look at the configIssue (http://vijava.sourceforge.net/vSphereAPIDoc/ver5/ReferenceGuide/vim.ManagedEntity.html#configIssue) for the object HostSystem connecting to vCenter, i.e. When this information appears. It contains a table of configuration problems and it is exposed in the API, which means that it can be accessed by using one of our SDKs including the vSphere SDK Perl

• ESXi hosts are disconnected from the vCenter (5.5)

  Hi all

  We have a little problem with our vCenter.

  We have two hosts that are connected to the vCenter, unfortunately, they are listed as disconnected.

  It seems that the problem are the SSL certificates on ESXi hosts that are no longer valid.

  If I replace the old certificates with new ones, that I have to restart the ESXi host, am I right?

  If so, that's the problem.

  We do not use any what automatic vMotion and as long as the hosts are not connected to the vCenter I can't manually, move right?

  Is it possible to connect hosts to vCenter without SSL?

  Sorry for my bad English, I'm not a native speaker.

  See you soon,.

  Johannes

  You need to replace the ESXi host SSL certificates.

  See the Docs for the replacement of ESXi Cert below.

  ttp://www.BlueBox-Web.com/2013/04/18/replace-ESXi-certificate/

  Documentation Centre of vSphere 5.5

  I had regenerate the ESXi 5.5 SSL certificates, which I did without any stop to virtual machines.

  Certificate replacement process can change based on the esxi version.

  According to the Doc, vSphere 6.0 Documentation Centre ESXi6 host must be rebooted to replace certificates.

  Anyway, in current state disconnected, you can try to regenerate the self signed SSL certs, restart management agents and try to reconnect host in vCenter.

  Thank you

• ESXi host running 6 VCSA disconnected from the vCenter

  Hi guys,.

  I have a weird problem with my vCenter build 6. Single cluster of ESXi hosts. Running VCSA 6.0 and 6.0 ESXI. Making a storage of the vCenter vMotion initially got stuck at 77% and the ESXi host running the disconnected from vCenter vCenter. But I can connect directly to the ESXi host with vsphere client and see the vCenter VM works perfectly well. If I try to manually connect host ESXi and vCenter, I get the error "Failed to contact the host specified") both are in the same subnet and VLAN. I can migrate to other virtual machines without problem. I even restarted the host and yet I am not able to connect to vCenter. The host connects to vCenter if I reboot vCenter, but after a few minutes, disconnects again (even if no task does run on this topic.) I have no HA or DRS enabled at this point that I build this new environment and only presented a single LUN as a store of test data to the cluster.

  Any ideas?

  OK, I think I fixed that or have at least a work around. So the underlying question was hiding ID mode/CPU EVC. I'm under the cluster to a level of EVC to reduce until I have migrate workloads from old environment and I think that this created a problem for the unit vCenter. To resolve this problem, I turned off the unit, directly connected to the ESXi host that had the camera running, edited the virtual machine and reset the masking of CPUID. Also, I've hidden the flag NX/XD of the guest. It's temporary (I hope) as once I increase the EVC to the Haswell, I will expose the NX/XD comments and test. For the moment, it is of the workaround I did. It may be of some use to someone.

• ESXi/ESX host disconnects vcenter Server 60 seconds after the connection

  Hello guys,.

  I recently made some changes to my VMware Lab.

  I'm under vCenter 5.1 with several hosts of ESXi 5.1.  My vCenter ran on one server ESXi 5.1 until I recently migrated there in a window of Windows 8 running VMware Workstation 9.   The vCenter is running normally and I am able to add hosts in stock, but they disconnect after approximately 60 to 90 seconds.  I believe that this issue is that the heart beats that are sent by the host do not reach the vCenter (port 902), I think that it is similar to the issue discussed in the following KB:http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1029919

  Here are my questions:

  1. the article describes download wireshark and run scripts.  Is there an easier away from do?  I'm literally just checking this single port of the ESXi host, there is no equivalent for telnet from an ESXi host?

  2 VMware Workstation 9 block ports or run its own firewall any?  Since this vCenter worked perfectly when running on the host ESXi 5.1 we know this isn't a firewall on the virtual computer problem, I have also checked the Windows 8 machine running VMware workstation and have verified that the windows firewall is disabled.  Windows firewall is not the issue. 

  Thank you

  Duncan.

  Just a quick question. A fact change of IP address of the server vCenter with migration of VMware Workstation? Maybe http://kb.vmware.com/kb/1008030 is related to the question!

  ESXi 4.0.0 Releasebuild-261974

  I have a host on the 16 who became disconnected from VCenter recently. I spent some time online means to join new host in VCenter, but each has failed so far. I'm not avoiding perform a reboot of the host due to production VMS are residing thereon. Also, I can't access the Web page for the host, which works very well for the other guests, we have running: https://

  I am able to ping both the IP address and the name of FQDN of the host successfully.

  I did the following things in the hope of resolving, who all have failed:

  1 restart the Management Agents on ESXi host from the windows of the customization of the system.

  2. test the management successfully and rebooted network management network

  It is an ugly one. At least a restart if not re-install. To minimize downtime, you can close out of virtual machines to the inventory and put them on another host/cluster.

• Mobile 5.1 ESXi host in vCenter unpublished 6 - license?

  Hi all -

  If I take an ESXi host 5.1, previously managed (under license) via a given vCenter (also v5.1) and its key in the inventory management, then I disconnect/remove this host from the vCenter 5.1 and connect it to a completely new vCenter, what happens to the host of license?

  It disappear and become a 60-day eval, or his license key moves WITH the host in the new vCenter?  (The new vCenter in this scenario would have absolutely zero license keys from host ESXi that apply to guests of ESXi 5.1 existing installs below)

  I was wondering what 'happens' in this scenario I have the document our so-called steps for migration.  Yes, I know that this could / should all be tested "in the lab" but don't get started me on that.  Thanks for any comments on what I can expect.

  My best guess is that the host will LOSE its license now, it becomes a 'standalone' ESXi host when disconnected and removed from the old vCenter (via the "Delete" command).  I want to just make sure that it is also fully functional, if she has run VMs on it at the time or not (although Yes, I'll put it in maintenance mode before removing the old VirtualCenter and join a new).

  And Yes, of course I have old games of the existing environment 5.1 ESXi license keys.  I'm just trying to set expectations as to what is happening in licenses-wise once I move the host from the old to the new vCenter.  I have all pretty well understood technical pieces, including AVS and DVS network considerations.  Thank you.

  The cmdlet Get - Log do not create the destination folder if it does not exist, so you will need to test for this condition.

  AFAIK, you don't need to connect to each ESXi individually when you are connected to the vCenter.

  Since the discharge of generated log file name is rather cryptic, I rename the file normally and add a timestamp.

  You could do something like that

  $clusterName = "mycluster.

  $FilePath = 'S:\Get-Logs\Logs\$($clusterName) ".

  If (!) ((Test-Path-path $FilePath)))

  {

  Novelty - ItemType Directory - Path $FilePath

  {foreach ($ESX to $varHost)

  $destPath = "$($FilePath)-$($ESX.). Name.Split('.') [0])"

  If (!) ((Test-Path-path $destPath)))

  {

  Novelty - ItemType Directory - Path $destPath

  }

  $logName = get - Log - VMHost $ESX - Bundle - DestinationPath $destPath

  If ($LogName)

• 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:

• 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.

• 6.0 ESXi hosts are no longer

  Hello world!

  I have a problem with VMware ESXi 6.0.

  I have a VMware Cluster with 3 6.0 ESXi host. Last night 2 ESXi host has become unresponsive. ESXi hosts concerned, responds to the ping, but unplug vCenter, unable to connect directly to the client host with vSphere and unresponsive on DCUI. The VMs - running concerned guests - became unresponsive (VMware HA cannot restart VMs, because the host has locked the VMs file). Only solution: reset the hosts. After hard reset hosts, HA restart VM on another host and host affected normal work. The problem occurd when high e / s (backup, at the level of the files inside the virtual machine) on HBA.

  In the /var/log/vmkernel.log , I see a lot of messages both "crash":

  WARNING: lpfc: lpfc_sli_issue_abort:9956: 1:3169 Abort failed: Abort INP: data: x 0 xcd0 x 8 x 98

  ScsiPath: 7133: Set retry timeout for demolition of TaskMgmt failed for CmdSN 0x0, State failure, path vmhba5:C0:T0:L0

  The configuration of the hosts:

  The host firmware versions are later.

  VMware installed on a USB stick (clean install, not upgraded), LOG dir on the CF data store.

  The storage and the side FC switches have no error/warning message.

  I see the VMware KB 2086025 and 2125904. In this KB article the symptoms are very similar to our situation, but our guests have the most recent version of the Emulex driver (KB articles: version prior to 10.2.340.18, our 10.4.236.0 version)

  I tried the latest Emulex firmware (version: 10.6.126.0, install and reboot host) but the host crash again and the same newspaper as above.

  Today a new problem, when I collect information on diagnosis (registers of export) of the host:

  • first of all welcome: unplug vCenter for seconds 3 times (State of heartbeat), and download of the newspaper failed, when the host disconnect, virtual machines (which run on this host) does not not on LAN
  • second host: connect download start, after the 10-minute purple screen:

  

  I have found no solution.

  Any ideas?

  Thanks for your help!

  Have you seen the question of host unresponse before 6.0 updated. If not, I suspect strongly this is due to "VMware KB: ESXi 6.0 the network connectivity is lost with the NETDEV WATCHDOG timeouts in the vmkernel.log". Try upgrading to the latest version 6.0 that contains the fix for this.

  The purple screen could be a different product bug and I doubt that it does not always happen. Based on the screenshot, it looks like collection Journal (vm-support) was going through some of the nodes of the VSI and failed at this point. So this issue could happen specifically only during some invocation of vm-support. Good to raise a complaint with the help of VMware.

• 5.1 ESXi host is showing that does not

  Hi all

  We are to vCenter 5.5 with Environment 5.1 ESXi hosts. On one of our ESXi hosts, we sometimes get to see 5.1 ESXi, (build 799733) host is not responding and the virtual machines on this subject are displayed as status disconnected at the end of their names.

  When this happens, we are able to ping on the ESXi host and virtual machines are also able to ping / react to what is good, but he continues to be on different hosts at different times, all what I do when this occurs is to try to reconnect on the ESXi host and it connects fine and machines virtual hosting on she will return to the State normal and everything will be normal on this host. I want to understand why this is happening at different times and on different hosts of ESXi and ensure that this should not happen again in the future or find the before root cause is even worse.

  so, could someone please look at this and let me know where to start troubleshooting this to find the root cause.

  Thanks in advance

  Your vCenter and ESXi host is on the same subnet? In any case, I recommend you take a look at this article and apply the patch suggested: VMware KB: hosts ESXi and ESX disconnect randomly VMware vCenter Server
