  Unfortunately, it seems THAT NUMA is disabled hardware wise. You can only activate it via the BIOS setting.

• Configuration of the network with several hosts (dVS/EtherChannel)

  Hey,.

  Let's say that there are 4 hosts, each with 2 NETWORK adapter connected to a switch. On the side of ESX, all uplinks are added to a dVS and the port group is set to 'Route based on IP Hash'.

  Host 1 > change of ports 1 and 2

  Host 2 > change ports 3 and 4

  Host 3 > change ports 5 and 6

  Host 4 > change ports 7 and 8

  The switch (Cisco) must be configured as:

  Port channel 1: 1 to 8 Ports

  OR

  
  Port channel 1: 1 and 2 Ports

  Port channel 2: 3 and 4 Ports

  Port channel 3: Ports 5 and 6

• VM starts not directly from the CDROM drive ESXi host

  Hello. I was looking for a long time another discussion for people who have had the same problem, I found it but the answers that the candidates are not useful for me. I explain my problem giving you as much information as I can.

  I have created a virtual machine in order to intall inside Windows Server 2K 3. The problem is that I can't make the start of the VM from the CD I put in the ESXi host CDROM drive. I installed ESXi 3.5 U4. For the virtual CD/DVD Drive 1 (only in the virtual machine), I chose "Host device" as the device Type.  The only option, it's for me inside this option is ' / vmfs/devices/genide / vmhba0:0:0.» The message I get in the console view is "Not found operating system"

  Storage adapters I in the ESXi host are: LSI1068E - & gt; vmhba2 where I see my RAID1 disk1. The other device is ICH10 4 port SATA IDE Controller - & gt; vmhba0 where I see the physical CDROM Drive.  I also have another device that is "USB Storage Controller" - & gt; vmhba32 where I also see the CDROM (but when I create the virtual machine does not allow me to choose this controller, vmhba32:0:0). This controller is a "SCSI" where alumni are "Block SCSI".

  I have also checked the box "connect to power on" in the settings of VM window. The CD booteable because unless I restart the ESXi host and I do boot from the CDROM it loads the Windows Setup program. Thus, the CD is OK and the CD-ROM drive is also OK.

  I don't know what to do and what to test. If I choose to boot the client machine, the virtual machine option starts ok. The problem is that I need to transfer all the contents of the CD by the network and right now I am using an ADSL connection.

  The server I have is IBM System x 3650 M2, which is compatible with ESXi 3.5 U4.

  I know I have another option is to boot from and ISO image. Here, I have a few questions. First of all, how to download the ISO to the ESXi host image? Do I have to use the RCLI? Secondly, I want to make sure that only a problem of booting from the CDROM or the problem is maybe the ESXi of CDROM drive is not recognized by ESXi, so I'll never be able to use it.

  Advanced averybody thanks.

  The discussion has been moved to the VI: forum ESXi 3.5.  It seems to be the case, but could check you that ESXi is load the IDE driver for the ICH10 controller?  This mode is the controller of the value in the BIOS?

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

  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')).

• Update DNS on the 5.1 ESXi hosts

  I have a cluster with 8 hosts where 6 I have DNS and NTP settings of a legacy domain and 2 current settings.  Existing domain controllers are still in place and there is trust between the two.  I would like to change the hosts so that they use all current DNS and NTP servers.  The directory services for all hosts is set to local authentication so that they are not included in the AD.  What is the impact of changing these settings?  What are the steps to follow?  It is also easy to put hosts with parameters inherited in maintenance mode, made the change, and then bring them back to maintenance mode?

  The steps that I ended up taking have been:

  -added a records in DNS

  -put the host in maintenance (always do before making changes) mode

  -remove the vCenter

  -connect directly to host and make changes

  -Add the host to vCenter

  Everything is in place and no problem.

• The upgrade to ESXi host that hosts vCenter comments

  Recently, we moved our vCenter Server in a virtual machine rather than running on a dedicated machine.

  A question I have for those running in this type of configuration are how do you for the upgrade of the host as comments from vCenter runs (for example ESXi 5.0 > 5.1)? We usually use Update Manager to perform the upgrade, so I was wondering if there is just more to use the old method of mode start since the level of the server installation CD or if there is another special way Im unaware of.

  Thanks in advance!

  If you have shared storage, you can connect to the host where you vCenter VM is registered, it off, remove the inventory, disconnect from the host, log in another host, browse the data store, add the vCenter VM inventory on the other host, turn on the vCenter VM and then you can remidate the other host using the virtual machine.

• 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}}

• Connect 2 ESXi hosts to array SAS MD3220

  I have two R620s who go to the server as a host for the VM for several web servers (in a Windows NETWORK load balancing) and two other R620s which will be considered as physical database servers (in a Failover Cluster) and have to apply to a single Bay MD3220 SAS. The DB cluster will host the databases shared on a virtual disk and a data store shared on another virtual drive on the Bay. ESXi hosts will store their vmx/vmdk files elsewhere on the Board.

  I'm still waiting for delivery of the second DB server, but in the meantime, I installed the first and he speaks with success to the table - I run MDSM on that server and the server is successfully connected to DB and filestore volumes. guess I'm having a little problem with the second server.

  I installed ESXi on both VM hosts. I guess the next step is to save in MDSM, but MDSM is not automatically host port identifiers as assigned. Does?

  My next guess would be to identify manually port host identifiers, but how can I determine what are their respective IDs? I couldn't see anything obvious in the BIOS.

  I have currently two independent hosts to VM with ESXi installed v5.1 - I have not created a VM vCenter again because the host does not have access to the storage Bay (!), so I can pair together for HA hosts, etc. As a broader question, given what I want to achieve, how should I be going to this topic?

  Indeed, you will need to register the VMware hosts in MDSM yourself. There is no agent to have a VMware host register automatically on the SAN (at the regular difference in Windows and linux).

  You may be able to find the WWN of the HBA SAS in the SAS controller bios.

  The only other way I know not to register the correct WWN with the server is intrusive, but not so hard:

  -Stop your Windows (cluster SQL) servers

  -Stop the VMware servers

  -power of the MD3220 downwards

  -power up the MD3220

  -power up to one of the servers Windows (one that has MDSM on it)

  -power up the VMware Server 1

  In MDSM, you can now save this first VMware Server.

  Turn on the other 2 servers and register the 2nd VMware Server.

  I found that only shutting down 1 VMware server is not erase the memory of the MD whose WWNS are connected and there is no way to find which ports you enter the WWN in question.

• 6u2 ESXi host nested on VMware Workstation for Linux referee v12

  Hello all, I have

  I have a lab environment virtual running in VMware Workstation for Linux v12, and my ESXi hosts do not work correctly on one of the virtual networks. All my troubleshooting suggests a problem with nested ESXi hosts that may be a bug, but I want to assure you that I did everything properly first. That's why I post here with the hope that if I made a mistake that maybe someone else can point out he me.

  Physical system

  8 core Intel Xeon 2.1 GHz CPU

  128 GB of RAM

  OS - kernel Linux 64 - bit w/3.19.0-32-generic Linux Mint 17.3 (fully updated from this announcement)

  VMware Workstation 12 Pro - 12.1.1. Build-3770994 (fully updated from this announcement)

  Nested ESXi host VM

  ESXi v6.0.0 (Build 3825889, completely updated from this announcement)

  4 cards 'physical' (only 3 used for now)

  -all use the e1000 NIC hardware virtual, but also tried vmxnet3 NIC with no difference

  -vSwitch0 use vmnic0 & 1 vmnet16 of virtual network in a pair of active / standby

  -vSwitch1 uses vmnic2 on network virtual vmnet18

  -vmk0 used for management on vSwitch0 and vmk1 for iSCSI on vSwitch1

  -"Promiscuous" mode and forged passes enabled on all Port vSwitch groups (activating or turning off these features makes no difference)

  Test performed until now

  I checked that all the IP addresses and network masks used are correct.

  With the help of vmkping I ping other nodes on the network vmnet16 with success.

  With the help of vmkping I tried to ping the other nodes in the network vmnet18, but that has failed.

  I have depolyed other non - ESXi VMs on the vmnet18 network, and they are able to ping each other, but are unable to ping or ping by the ESXI host.

  I tried various material virtual NIC as mentioned before, but without changes in the results.

  I tried to use only local network instead of the vmnet18 guest network segments with no change in results.

  When I find out the status of the network adapters on the ESXi host through vCenter or host incorporated client vmnic0 & 1 time display network information, but vmnic2 shows no networks. Yet, I know that there is a network with different VM communicate on it. Moreover, I was able to get all of this work on a Windows system running 10 Workstation (this is the laptop that my employer gives me with).

  Having built nested ESXi labs on different platforms as well as physical environments in the past, I'm very confused as to why I can't get this special configuration to work. At this point my gut tells me that this is probably a bug any with the nested themselves ESXi hosts. Since I can get all this work on vmnet16 including the management of ESXi hosts and the VCSA that I use, I am sure that my vSwitch configuration is correct (other than the IP address space and vmnic configurations is bascially the same). Because I can get other virtual machines to communicate over the network vmnet18 I don't see how can be a VMware Workstation for the issue physical Linux host. Is there something obvious I'm missing here? I read on the ESXi hosts nested under VMware Workstation after having known problems and bugs with networking. If anyone else has experienced this?

  Thanks for any help others can provide!

  Kind regards

  Patrick

  Well, the problem is now resolved. The problem was what covelli was trying to explain, but I couldn't because the physical host network adapters being mentioned.

  The problem on the Linux host, but it was a problem of permissions with the virtual Ethernet adapters. The following article has the fix:
  With the help of Ethernet virtual cards in Promiscuous Mode on a Linux host (287) | VMware KB

  Even if I launched the workstation under the root user I have yet met this problem and which still makes no sense to me, but change the permissions solve the problem. I was not getting an error message on my Linux Mint and Ubuntu system, but when I tried on a second box of Linux Mint that I just got the error has been generated, and the error message was the above link it contains.

  So, here's what I learned:

  (1) the question has nothing to with a VMware Workstation definition that you can configure.

  (2) the question has nothing to do with a physical network card.
  (3) the question has nothing to do with any vmnic on the nested ESXi host.

  (4) apparently virtual Ethernet adapters are not the correct permissions when created.

  All you have to do to fix this is:

  (1) open a terminal.

  (2) run the command ' sudo chmod a + rw/dev/vmnet * "(don't forget to run this each time that you create a new virtual network).

  You can also create a group, as shown in the link above and simply give this group the correct permissions. Personally, I think it's easier to just give everyone the rw permission.

  I appreciate the help that others have offered. I did not understand what was asked for in previous answers because of the terms that have been used.

• Permisions required for mounting NFS on ESXi host

  Hi team,

  In our java application uses) use API VMWARE to mount the NFS datastore on the ESXi host. But to do this, we need the ESXI root permissions. Because having credentials root door reached the safety of the system, we would like to create a user with the required permissions will be sufficient to add the mounting NFS on ESXi host.

  But do not know how to see the permissions required for the Assembly of the NFS on ESXi host. Pointers would be useful.

  Thanks in advance,

  Hello

  Storage permissions lies in the roles of Group of data store.

  You should have a default profile role of storage in your vCenter.

• 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...

• Welcome to the upgrade to ESXi 4.0 to 4.1 and 4.6 of view

  
  Hello everyone, I have a question regarding the upgrade of my esxi hosts that are running a cluster View 4.6.

  Overview of my environment:

  The current 4 ESXi hosts run 4.0.0 261974.  These hosts are UCS B200 M2 blade.

  I need to add a 5th host for abilities and bought a new UCS B200 M3 blade.  The M3 blade only supports ESXi 4.1 U2 or more so I can't install the same version running on my 4 current hosts.

  My question is, what would be the best practice to get the blade M3 installed and in my environment?

  Should I install the 4.1 u2 on the M3 blade and attach it to the cluster with the 4 hosts running 4.0, and then you spend the remaining 4.0 hosts one at a time?

  or

  Can I upgrade the 4 hosts first run 4.0 to 4.1 u2 or u3 and then install and join the M3 host?

  In addition, please include any documentation useful update, or links to, that would be great!

  Thank you!

  You consider right. Do an upgrade at a time. 4.0 and 4.1 also can coexist without problem, but the ideal is to upgrade.

  Good luck with that.

• ME of ESXi host

  Hi all

  I have a doubt about the ME of ESXi host. I know, it is assigned by vCenter Server ESXi hosts & when each and every host have even number of data store, it is used to set the master host in cluster HA.

  My question or doubt is-

  When he is assigned to the host? At the time of the addition when adding in vCenter Server Instance or cluster HA? Please clearify?

  IIRC when adding to vcenter, I don't think it changes.

  Here's something interesting:

  The electoral process is defined by an algorithm with two published rules. For the first time, the host with access to the largest number of victories of data warehouses. In case of tie, the second rule comes into play: the host with the lexically highest Managed Object ID (ME) is chosen. When the attempt to rig these elections as lexically here means, for example, this host-99 is actually greater than host-100.
