• vMotion between two hosts with different version?

  
  Hello

  Can I vMotion VM between two hosts with different version? For example, a virtual machine of esxi 6.0 5.5 esxi and esxi esxi 6.0 5.5 vMotion.

  Thank you.

  Yes, it will avoid you to move.

• 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 on ESXi host 5 root in vSphere Cluster

  I would like to change the root password on my ESXi 5 hosts that are in a cluster of vSphere. I can just go into the console and change the password? The traps?

  I found the article below which says that the host ' ' must be reconnected. Not sure what would cause 'may' come into play.

  Thoughts?

  Thank you

  Basically, the root password is only required for the initial connection, after this vCenter Server uses the account vpxuser to communicate with the host. However, according to for example ESXi root password change vCenter connectivity and there could be reasons of "update" the password (i.e. to reconnect the host). Not sure whether it's design or a bug! Maybe it's that note in the article you mentioned refers to.

• 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,.

  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.

• Emulex a Manager command not showing material status of esxi hosts

  Hi all

  We use Emulex CMO for the updated release of the HBA firmware via vcenter, 4 Esxi host (all in the same cluster) do not display details of HBA in the CMO and we were not able to update the firmware on these hosts.

  Hand this group, we can see the details of HBA and update firmware for all other hosts in different cluster

  Any help or suggestion will be useful.

  Ajay.

  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.

• vSphere Cluster with different Versions of ESX

  We plan to upgrade our ESX ESX ESXi 5.1 4.1 host our preferred is method of upgrade via the Update Manager. In the 5.1 Update Manager documentation it provides the following:

  "ESXi 4.x to 5.x UPGRADE ESXi is supported and ESX 4.1 for ESXi 5 MIGRATION is supported. Anyone know what are the difference between an upgrade and a migration? Am I'm going to completely rebuild the host or will it keep its settings.

  Also run different versions of inside ESX (ESX 4.1 and 5.1 ESXi) the same cluster, supported? Any other consideration when running different versions of the same cluster. It will be a temporary problem while we work to get all hosts upgrade.

  Thank you.

  Migration - is where you perform the migration of ESXi 4.x for a new installation of ESXi 5 x

  Upgrade - is where you upgrade the existing ESXi 4.x host which will allow you to save the configuration of the host - things to keep in mind before you go is to ensure that existing equipment is supported by ESXi5 - you want to place the host to be upgraded in Maintenance mode - vCenter must be upgraded first

  As long as vCenter is upgraded to version 5.x versions of ESXi can coexist in a cluster

• MSSQL server VM cluster should be in the same host or different hosts with RDM

  Could someone me on how to place the code SQL cluster s VM with RDMs in ESXi hosts for advice.

  What is the best practice to place the SQL VM s in ESXi hosts.

  Affinity or an anti-affinite...?

  Appreciated your valuable answers.

  Depends entirely on the use case.

  • 2 MS SQL nodes on the same host to see the availability of the software
  • 2 nodes on different hosts to see the availability of the equipment

  I'd say MS Clusters on the same host (at the time of HA and vSMP FT) are redundant VMware features and represent an increase in management fees. The MS cluster on hosts provide something in addition to what VMware vSphere alone can provide!

• replication between different versions of ESXi vSphere

  Hi all

  Is it possible to use replication between different versions of ESXi vSphere? the scenario is as follows.

  Source site:

  vCenter 6

  RS 6

  Replication Unit 6

  5.5 ESXi

  The target site:

  vCenter 6

  RS 6

  Replication Unit 6

  6 ESXi

  I understand that vCenter, SRM and VRA must match and vSphere replication 6 is compatible with ESXi 5 upwards and it is the vSphere host in the source location that replicates on the VRA rather than a host of ESXi target so it should work, but I wanted a certain Yes/No.

  Thank you

  Definite yes.

• Same version SRM between sites, but different versions of ESXi

  Like many people, my recovery site is filled with older hardware. And now we have developed on an issue where ESXi hosts on the recovering site cannot be upgraded to the same version of ESXi as a protected site (protected site = 5.5 U2, recovery site = 5.1 U3).

  The vCenter site recovery is the same as the vCenter in the protected site (5.5 U2), and the SRM on the two sites is the same (5.5).

  Question: this should be OK, right? as long as the vCenter and RS versions on both sites are the same, I have different versions of the ESXi servers, without problem? (assuming that I keep an eye on the VMtools version and versions of VMS virtual material, so I do not use anything that is not supported on the recovering site)

  Thank you

  Hello

  You can have different versions of ESXi server, but you should check if these versions are supported by the version of MRS who is 5.5 in your case.

  SRM 5.5 does not manage ESXi 5.5 u2 and u3 5.1.  SRM 5.5.1 supports ESXi 5.5 u2 but it does not support ESXi 5.1 u3.

  If can use SRM 5.5.1 and downgrade 5.1 to 5.1 u2 u3 which is supported.

  BTW, vCenter version is 5.5 u2 is supported with MRS. 5.5.1.x.

  Thank you

• Share of CPU between ESXi hosts in a cluster?

  Is it possible to configure a cluster with a pool of CPU resources such as all CPUS of all ESXi hosts in the cluster are in the pool and if a virtual machine starts using more CPU that's current host has it can draw another ESXi host CPU to deal with?

  A virtual machine can use CPU only from the host where the virtual machine works... There is no way to allocate CPU of multiple hosts to a single virtual machine.

• ESXi host bios version and server model number

  Hi all

  I have the script that will display the version of the bios of the esxi host.

  can we add more lines to get the server esxi host (such as Dell R910, R720... model number HP, IBM) with serial numbers. and export it in excel or csv format.

  Script to get the version of the bios is listed below.

  $report = @)

  Get-view ViewType - HostSystem | %{

  $row = "" | SELECT name, "BIOS Version", "BIOS Date"

  $row.name = $_.name

  $biosTemp = ((($_.)) Runtime.HealthSystemRuntime.SystemHealthInfo.NumericSensorInfo | Where {$_.} ({Name: like "* BIOS *"}). Name - split "BIOS") [1] - split "") ""

  $row. "" BIOS version "= $biosTemp [0]

  $row. "" Date of the BIOS ' = $biosTemp [1]

  $report += $row

  }

  $report

  his put Out just like that

  
  

  

  Thanks to all in advance

  This is the version of the firmware of a network card.

  This can be done like this

  Get-view ViewType - HostSystem |

  Select Name,

  @{N = "BIOS Version"; E = {}

  $script: biosTemp = ((($_.)) Runtime.HealthSystemRuntime.SystemHealthInfo.NumericSensorInfo | Where {$_.} ({Name: like "* BIOS *"}). Name - split "BIOS") [1] - split "") ""

  {{$script: biosTemp [0]}},

  @{N = 'BIOS Date'; {E = {$script: biosTemp [1]}},

  @{N = 'Seller'; E={$_. Summary.Hardware.Vendor}},

  @{N = ' series'; E = {}

  $script: esxcli = Get-EsxCli - VMHost $_. Name

  $script: esxcli.hardware.platform.get (). SerialNumber

  }},

  @{N = "Firmware NIC"; E = {}

  $script: esxcli.network.nic.get ('vmnic4') .driverinfo .firmwareversion

• Cannot access ESXi host in Vcenter after moving to accommodate different subnet

  I moved a different host EXSi 5.5 on a new subnet at a physical site.  The host has been identified by IP not the DNS name.  After the start of Vcenter, I realized my mistake.  The host is always identified by the old IP so it appears as disconnected.  I was hoping I'd be able to simply change the identification of IP address, but have not been able to see how to do this.  I also tried to remove the host (this configuration has a data center and a host), but I can't do it.  I can't add the host (with the new IP address) I get an error message that the data store is identified with the original host.

  Is there an easy way to this?

  Welcome to the community - you need to remove the old entry in your inventory (using the command delete inventory) and then re-add the ESXi host FULL domain name.

  I also moved it to a more appropriate forum-

• Add new host esxi 5.1 for the existing cluster of vcenter

  Hello

  I would like to add a new host Virgin esxi 5.1 to an existing cluster from the vcenter. What are the things that I have to preconfigure on the host before add you it? I configured the network already, storage will be implemented when I add it to the cluster, right?

  So, what I ended up doing was just set up time, networking and dns. I then added the host while he was in maintenance mode. I have a Compellent SAN storage and im using a folder in compellent to map all my Lun, then I can just add a new host in this folder, and it will automatically map all volumes to the newly added host once I go into vmware and make a new analysis on the FC HBA host (do FC fabric SW zoning first of course). I then added a file .locker on one of my SAN LUNS scrach location/newspapers. She's.

• 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.
