Change password on ESXi host 5 root in vSphere Cluster

• Best practices for the management of user access in ESXi host without 'root '.

  What is the best way to make the management of the user access to the ESXi host after you disable the default root account. Is it better to create induvidual accounts

  Via vCenter or intergrate Active directory or any other specific way.  Please help me to clarify this point. Thanks in advance for your answers.

  With the release of ESXi 5.1 it is possible to create an account on the ESXi host and assign them Full Admin privileged but there are a lot of admins of loggin in each ESXi host and user account creation.

  I would like suggestions to add the ESXi to AD and add the authorization based on domain accounts.

• Can I use the total amount of resources (cpu/ram) of two esxi hosts if I place a cluster so that a single VM gets all resources?

  I use vCenter 5.1 with two esxi 5 guests, both exactly the same (Evga SR - 2 pc with two Intel x 5670 each) with the exception of the disk storage. Processor x 5670 a 12 hearts if HT is enabled. Since then, I have 4 of these processors that would be 48 cores. Each processor is clocked at 4 GHz for a total of 16 GHz. Each host would also 24GO of total Yes 48 GB of ram.

  I doubt that this is possible, but what I want to do is to install a virtual machine like Win 7 x 64 and give all these resources to it... all of them (perhaps leave some carrots and ram aside for guests of esxi, of course). This vm is run to 16 GHz? It would be nice if we could create a cluster with a Setup like this and give the "total available resources' for a single virtual machine running on a esxi host.

  I doubt that this is possible because I've tried that before and it wouldn't let me create a virtual machine with this number of nuclei or ram because he said that they were not available or something... as if to suggest that I can only use the total amount of resources to AN esxi host.

  There may be another way I could give this 16 GHz machine?

  Could not assign more resources to a host to a virtual computer.

• Change password in the hosted Application (RDSH)

  Hello colleagues!

  VMware Horizon Client 3.4.0 build-2769709

  VMware View 6.1.1 construction-2769403

  VMware vSphere 6.0.0 2776511

  For users of an application published. How thay can change the password for authentication in Windows AD, when they see that the advertised program window, and the combination ctrl + alt + del or ctrl + alt + end (physical keys) does not work?

  TNX for help!

  They have to use Ctrl + Alt + Ins to send a Ctrl + Alt + Delete to the RDSH session.  Then they can change their password.

  Also, if a password expires, by connecting to the sight connection to the server with the Client of the view, they will be asked to change their password.

• ESXi hosts are divided into DRS cluster

  Hi all

  I'm going as well as I can explain it... In the case that I'm not being very clear, please not hesitate to ask me more questions.  Here is the scenerio:

  (1) I have a Blade IBM H chassis has 7 in there (host ESXi) servers

  (2) I have implemented a DRS cluster with these 7 Hosts

  (3) I have active VMotion and HA

  (4) the question is that 2,3 and 6 blades can only ping between them on the VMotion network and therefore can migrate to eachother

  (5) blades 1,4,5 and 7 only can ping each other and can therefore only VMotion for eachother.

  (6) this problem started to happen over the weekend, one day, and when we came back to work on Monday, we realized that the 3 hosts were not communicating on the network correctly.

  (7) one thing I noticed is when I unplugged all the DRS cluster hosts and then I connected to them again I realized that all guests were able to successfully connect to the Cluster but the hosts 2, 3 and 6 failed on the AP.  When I then reactivated the AP, he worked on these 3 guests.

  (8) due to this problem, I had remove the feature of DRS cluster because the system could not migrate the machines for guests.

  (9) one last thing I noticed was that when I VMotion, the machine I have VMotion loses network connectivity.  I must go to the publishing settings and disable the NETWORK adapter and re-enable the NETWORK card

  I hope someone can help with this problem

  Thank you all,.

  Antonio.

  Basically, the spanning tree Protocol is used to avoid loops in a bridged network. Please take a look at for example http://en.wikipedia.org/wiki/Spanning_tree_protocol for details on how it works.

  However, the individual switch ports that serve as uplinks for ESXi must be configured for Spanning-tree portfast.

• ESXi hosts in different versions of cluster

  Hi all

  There are problems associated with a single host in a cluster to upgrade to version 4.1 while the other 4.0?  Is vmotion, drs, HA will continue to work properly?

  Yes, you can. However, they must be managed by vCenter 4.1. All the features works fine using the mixture of versions

• change password, the customer vi, minimum password complexity requirements.

  I installed esxi 4.0.

  I do not change the password, because he complained minimum password complexity.

  So if you want to change the password, go to:

  Users and groups - & gt; Select the root user, select change.

  and change the password.

  An error is generated when you change the password:

  "A general error has occurred: passwd: authentication token passwd error handling.

  This means that I am not meet the password complexity requirements.

  What are the complexity requirements of password on esxi for the root user?

  Hello

  Don't forget to include a special character, one uppercase letter and number your password and you will hit all the basic requirements. Also, the password must probably have 7 or more characters.

  Check if the port TCP 5989 (incoming and outgoing) is open to allow CIM transaction traffic pass between the host ESX and vCenter Server and vice versa.
  DMZ host is managed by a server vCenter Server outside the DMZ. It may occur if the port 5989 is blocked, even if ESX and vCenter Server are in the same network.

• Change the password for root to an ESXi host

  Hello

  I need help to get a script VCO that change password for root to an ESXi host.

  In PowerCLI is the Set-VMHostAccount cmdlet. I searched in VCO API... I have not found or something similar.

  I found the object of VcHostAccountSpec but seems it only works with "Host Profiles" and my licenses are Standard and Enterprise.

  http://www.VMware.com/support/Orchestrator/doc/vco_vsphere51_api/HTML/VcHostAccountSpec.html

  Any idea?

  Thanks, Roberto

  Another option would be to connect to the ESXi host with vCO plugin SSH and run the command "passwd" remotely. Haven't tried, but in theory, it should work.

  @Tim - we try to keep the compatibility of the existing whenever possible plug-ins vCO so PowerShell module should work with the latest vCO relies.

  ---------------

  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

  }

  $varHost = get-Cluster-name $cluserName | Get-VMHost

  {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)

  {

  Rename-Item - Path $logName - NewName "$($destPath)-$($ESX.). Name.Split('.') [0])-$((Get-Date).) ToString('yyyy-MM-dd-hh-mm')).

  }

• 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:

  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.

• Change of identification 5.0 ESXi Hosts DNS

  I have a 5.0 vSphere infrastructure not integrated with Active Directory.

  Either the vCenter and ESXi hosts have a DNS identification that uses a domain name that is identical to an existing Active Directory domain.

  To avoid potential conflicts, I plan to change the domain name in the DNS configuration, as described on page 74 of the manual on the https://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-501-networking-guide.pdf page.

  Can I just change the DNS domain name without having to restart ESXi hosts?

  The domain name DNS influence the affiliation of ESXi in a cluster (not integrated into AD)?

  Should I change the name of the DNS domain of the vCenter as well?

  Is there anything else I should consider?

  Concerning

  Marius

  I recommend you change the domain name on all systems related to the vpshere environment.

  Don't forget to also change your dns server DNS records. I guess they are hooked up with the right dns name vCenter?

  otherwise, esx server and vcenter server can not see the other...

• ESXi host change IP back to the old Configuration in vCenter

  Hi all! I'm having a problem with a host computer in my vCenter. I had 2 guests and both were in the same network. I moved to a remote site and change its IP from 10.10.2.253 to 10.10.3.250.

  While I'm trying to connect it to the vCenter, he connects well then (in vCenter) he's trying to connect to his old address IP 10.10.2.253.

  I have reset the vCenter, database, but it still does not work. When I move first the host at the remote site, I did not disconnect. I deleted it just (may be the source of this problem).

  Can someone help me on this one? A big thank you.

  Hi Alex,

  is it possible for you to create a record of host DNS (A) for this remote ESXi host name and then add to vCenter using its FULL domain name rather than IP address?

• Change the path information for ESX ESXi hosts to access

  Hello all! I hope you guys can help me.

  I have about 47 hosts that I need to change it Round Robin storage path information. If I make the change in vCenter and restart the host it again changing fixed. So, I thought that I should change it to the level of the host through esxicli.

  I have about twice as many LUNS of the Hitachi SAN. I'd like to see if it is possible to make the change in all areas, in some way, or I need to make the change by host? Also, is there anything that I need to change sides San so that it works or not.

  I saw this VMware KB: modification of path information for ESX/ESXi hosts to access and assume that it is the best plan? But did not know of all put into custody, if necessary, that everyone ran to when doing this?

  You will need to make the change by the host and the KB you'll find is the right method.
