Hi all, Due to a series of circumstances we ended up with the following situation last night: - One out of four domain controller was offline, within the same time period we had to restart the vCenter server (VCSA) without success. To our surprise vCenter didn't came back up again, a whole bunch of services did not start. Restarted VCSA again... the same result again. It took a while to figure out which service was the first one failing, turned out it was "lookupsvc". Knowing that I was able to find the log to that paticular service.  What I found in there was quite surprising to me, a lot of "Can't connatct LDAP Server" errors. We then desided to move forward and take online the fourth domain controller again. (Which wasn't that easy w/o vCenter running.) After doing that, vCenter started flawlessly. We are running VCSA 7.0.2 Buid 18356314 Now, here is my question/concern: How can it be that vCenter won't even start if only one domain controller is missing? Or in other words, what do I need to change so that vCenter is not pointing to only one domain controller? Any hint is very appreciated... Cheers Christian

Hi community, I am running a vCenter server installation (6.5 / 8024368) on Windows 2012 R2. Last week I changed the IP configuration from dual-stack to IPv6 only. IPv6 is working without any problem so far, no connection issues at all. After that I also changed the SNMP receivers to an IPv6 address under <vCenter> -> Settings -> General -> SNMP Receivers, "Port" and "Community string" is unchanged. My desired configuration was accepted. But now, everytime an Alert is triggerd I got the following error message: While we ran with dual-stack and an IPv4 receiver was configured we had no issues with SNMP. Am I doing something wrong?

Hi all, I just wanted to download the latest driver for my ESXi hosts from vmware.com. Then I got a little bit confused, the version numbers of the Emulex driver 'elxnet' are decrementing. Example: 11.1.196.3      Release Date    2016-09-30 12.0.1115.0    Release Date    2018-04-12 11.1.183.654  Release Date    2018-06-08 Which driver should I choose?

Hi all, I am currently working on some automation scripts to setup Windows Server on VMWare based on VM-templates. All the scripts are Powershell-based. Workflow: [Invokation-Script (local-server)]   -----WinRM---->   [Remote-Script (remote-server)]   -----PCLI/vAPI----->  vCenter The Invokation-script uses "invoke-command" with session-option "Credssp" to allow second hops connections. The PowerCLI modules are loaded on the remote-server. The scripts executed on the remote-server are located on a network share. So far so good. 14 out of 15 scripts are working flawlessly. The problem is caused by one script, or more precise by one command -> Set-NetworkAdapter. This is the failing script: $ProgressPreference = ’SilentlyContinue’ Import-Module VMware.VimAutomation.Core Import-Module VMware.VimAutomation.Vds Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false | Out-Null Connect-VIServer -Server $vCenterServer $VM = get-vm -Name $Hostname $VMNetworkAdapter = ($VM | Get-NetworkAdapter)[0] Set-NetworkAdapter -NetworkAdapter $VMNetworkAdapter -NetworkName $VcPGName -Confirm:$false   Disconnect-VIServer -Confirm:$false -Force If I execute this script with the paramete "-WhatIf" set for the Set-NetworkAdapter command everything works fine. If I remove the "-WhatIf" switch the VM's network adapter gets reconfigured (Task shows up in vCenter as 'completed') but the script hangs an it does not return from the remote-sessionThe session to the remote host is then locked or busy and i have no chance to get any return value or reconnect to this session. Other commands like "Set-VM" are working with the exact same type of script. Is there someone with similar experiences? Is this a known issue? I really appreciate your help.

Hi all, I recently installed a new instance of vRealize Operations Manager 6.1 as an appliance. Everything went well during installation and configuration. I was able to configure the vCenter Adapter and it is collecting data. Our vCenter is of version 5.5. Since then, I've been trying to add our SSO instance as authentication source, without any success. Every time I enter all the necessary fields in the "Add Source for User and Group Import" and click the Test-button, a message is displayed saying: /*** Failed to retrieve Single Sign On SSL certificates. Failed to retrieve SSL certificate. ***/ I don't think that the problem is related to user authentication problems or permissions. I tried with different user accounts getting the same error all the time. With a browser I am able to access the URL: https://<SSO-Host>:7444/lookupservice/sdk and download the certificate. Where is the problem located (SSO or vROps)? Is someone else experiencing such a problem? What could be the problem causing this error? Thank you guys and best regards.
