• Retrieve the IP address of the network on ESXi management card

  Hello

  I'm trying to change the settings of a host ESXi from DHCP to static IP.  I looked on forums setup scripts, but they seem to rely on obtaining some of the parameters of the local host where the script runs and the option is not available for me.

  I booked the IP addresses and set the appropriate DHCP settings so that the ESXi host starts and gets the correct IP address, DNS, DG name, and the parameters of the DNS server, but now I need to change to static.

  I need to extract the current settings that are correct and fill in the variables $HostIP and $HostMask

  SE connect-VIServer-Server 172.19.1.101 - root user

  $HostIP =

  $HostMask =

  $VMConsole = get-VMHostNetwork - ErrorAction inquire

  $ConsoleNIC = $VMConsole | %{$_. VirtualNic} | Where-Object {$_.} DeviceName-like 'vmk0'}

  Game-VMHostNetworkAdapter - VirtualNic $ConsoleNic - $HostIP - IP $HostMask subnet mask

  Any help would me much appreciated.

  Thank you

  Alasdair...

  The Get-VMHostNetworkAdapter cmdlet should give you this information.

  Something like that

  $vmkAdapt = Get-VMHostNetworkAdapter | where {$_.Name -eq "vmk0"}
  $HostIP = $vmkAdapt.IP
  $HostMask = $vmkAdapt.SubnetMask
  $VMConsole=Get-VMHostNetwork -ErrorAction Inquire
  $ConsoleNIC = $VMConsole | %{$_.VirtualNic} | Where-Object { $_.DeviceName -eq "vmk0"}
  Set-VMHostNetworkAdapter -VirtualNic $ConsoleNic -IP $HostIP -SubnetMask $HostMask

• Network problems intermittent management with more than 1 works ESXi

  Hello

  I had problems since installation with our 2 x ESXi 5.5 nodes running on a Dell VRTX system.

  If I had to run 1 ESXi nodes on its own, it works perfectly, no problems what so ever, but as soon as I start the 2nd node they network for the management network connectivity problems.  However any virtual machine that you are running on them have no problem at all.

  The easiest way for me to check it comes to ping the management network and it will be on one of the nodes timeout, then it will randomly and knitting on this node but timeout on the other, they will never return a ping at the same time.

  
  If anyone has experienced this before? I fight to see if there is a problem with the installation on the ESXi hosts, the network Dell VRTX or our NetGear switch.

  I tried a lot of solutions and been through the different pages of VMware KB but can't seem to find something that suits him.

  The network Dell 8 physical ports are all in one LAG with 2 nodes added, I tried the distinct lag, but that made no difference, I am focusing now on if it is a parameter of VMware to see where that gets me.

  That's how the two nodes are configured.

  

  Solved!

  Finally, I spotted the problem, and VMware technical support fixed it for me.

  The MAC address of each management network was the same!, for some reason, the host of the 2nd got the MAC address of a NIC to host the premiere, don't know how its possible but VMware support restored all of the network settings from scratch and it picked up the correct MAC and works.

  Thank you all for your suggestions.

• Question quick bonehead: ESXi management network?

  Hello

  Didn't find it in the docs still... Managing IP network that is configured on the ESXi console:

  Does it become part of any another logical network later, for example the VMotion network - or is it independent?

  I'm trying to find out where to place; so far, I have:

  net iSCSI (private)

  NET vMotion (private)

  NET management (LOM and other things)

  Main DvSwitch (public internet)

  I assumed that the ESXi management IP is purely the hook to vCentre control one or several hosts - in which case, for us, it could logically go on the net public or management of the net, as long as he has a gig connectivity - would it be a reasonable assessment?

  Thank you very much

  Tim

  The net vMotion fit into this net managemnet - or is it physically separate?

  No, vMotion traffic moves the load of the computer virtual from one host to another. This traffic is not encrypted and so - for security reasons - the vMotion network must be a separate private network. Depending on your topology (1 GB, 10 GB), you can consider using cards dedicated for vMotion to provide the necessary bandwidth.

• The Peer Name Resolution Protocol service (PNRPsvc) or peer network (p2pimsvc) Identity Manager service does not work

  I get the following error message when you run windows network diagnostics. I ran the diagnosis because I have a network with Win 7 Ultimate 64 bit on a computer and WinXP 32 bit on the other.  Curiously, I can easily see and manipulate all files through the firewall of Windows XP. Either way, Windows XP can not see files on Win7. I can drag files to the shared folder, XP can see them, but can not open the same when I enable the share using Win7.  I can see the Win7 computer name and I have a home network without password. When I click on the folder with XP, the error popup grey box says that I might not have permissions to access these files. Contact the administrator of systems etc. My network has the same name on both computers, so I feel totally betrayed by what is happening here. There should be no problem but there is a.

  Hi MarkWebber,

  Method 1: I suggest you to follow the link provided below to start your computer in safe mode with network.

  Advanced, including safe mode startup options

  http://Windows.Microsoft.com/en-us/Windows7/advanced-startup-options-including-safe-mode

  If it works fine in safe mode with network, try to put your system at startup mode minimum state helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.

  See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

  How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

  http://support.Microsoft.com/kb/929135

  Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.

  Method 2: Studied the problem and found the solution. A file has been corrupted and remove he got running PNRP service. The file has been re-created correctly when the PNRP service started upward. Here is the file for future reference:

• Make a little a bood by setting the switch 1 VLAN other than ALL - lost to ESXi management

  Hi all

  As the title says, I mucked this up a little bit. I have two virtual switches configured, one with all my virtual machines on three cards attached network, and the other with the management and interface card NETWORK attached.

  I thought that I have would combine the lot in a single switch and have the cards connected to the simple switch. Everything is VLAN'ed switch0 was set up at the trunk all the VLANS, as was the segment of management - although this should be in one VLAN specific. I've updated the Switch0 simply use the VLAN segment management and connectivity quickly lost the device to ESXi. All virtual machines on their VLAN specific are OK on the second switch.

  How can I return a network access ESXi?

  Console access is available, but I seem to have lost Out Light control will have to physically go to the machine.

  What a prick!

  Chris

  Couple of questions to understand the actions performed by you:

  I've updated the Switch0 simply use the VLAN management segment, and quickly lost connectivity to the device ESXi--> do you mean WHAT VLAN ID changed to 18 0 (none)?

  

  The virtual switch was set to pass all THE VLAN the Port VMkernal (Management Network Group) has been updated with "All THE VLAN", I went it to the VLAN (18)-->, you gave VLAN ID as 18 and your single NIC - VMNIC 0 is interconnection to VLAN 18?

  In simple words - you physical NIC 0 visibility to VLAN 18 or not (you will have to ask Admin network) - double else check your wiring asks that you made at the time of Installation

  For this kind of connectivity issues - you need problems like RSA/ILO/DRAC remote console based on the style of the material.

• Virutal Center can work next to the Vmware ESXi management package

  Hi all

  VMware currently has a promotion on Vmware ESXi management kit which is basically a Virutal Center Foundation license. That being said if you already have a virtual Center Server for all of your ESX servers could run a 2nd VMware ESXi management kit virtual Center Server for all your ESXi servers in parallel? or they will conflict with each other?

  My understanding is you can run as many virtual servers Center like you license but you can have than 1 ESX Server any attached to 1 Virutal host at any given time.

  We run 7 instances vCenter, so yes it is possible.  In addition, as you said a host ESX (i) can be managed by a single instance of vCenter.

• Path to upgrade VMware ESXi Management Kit

  I am interested in the offer of VMware ESXi Management Kit, but want to know if it will work with our plans for the future. I am particularly interested in the vCenter Foundation to allow us to track the performance of the server.

  At the moment we have an ESXi server and could get a second in the near future. End of the year, however, we plan to invest in standard with HA or possibly Enterprise with VMware vMotion. That we will be able to use the Foundation of this package vCenter in this future configuration? The host licenses are only for ESXi and we will have to buy new ones? If we do not upgrade vCenter or host is a way of evolution at discount prices or we will have to buy new ones?

  Budget is a problem then if we cannot reuse this in our final configuration so I won't be able to justify the cost.

  Thank you.

  vCenter Foundation lets you connect an ESX host 6CPU value.  Is not serious ESXi or ESX.  If you use two connectors boxes, then as soon as you add a 4th host computer, you will need to update your vCenter license.  There is a reference number which allows a foundation upgrade to vCenter Standard.  What it is offhand, I don't know, but your dealer can help you with that.

  In regard to 'free' with vCenter ESXi usage, you can not.  You must register (at least) Foundation for each ESX/ESXi host, you want to manage via vCenter.  Pay the $995 (list price) gets you the "VirtualCenter Agent" that is needed to connect to vCenter.  Note: You can install ESXi, play with it for as long as you want, but once you want to attach to vCenter, you will need the license... but there is No change to the ESXi host... you just load the license file in vCenter and you'll be all set.

  Hope that helps!

• 5.1 ESXi management no connectivity network with two network adapters connected

  IBM H chassis equipped with blades HS22

  Blades use Broadcom 5709 s dual gigabit NIC

  ESXi 5.0, system worked very well with both NICs connected (static IP) in network management parameters (able to ping in and out). Completed the upgrade to ESXi 5.1 preserving VMFS datastore. After the reboot, management network shows two NICs connected to static IP always assigned but I have not any (impossible in our out ping) network connectivity. If I disable one of the network cards and restart the management network, I can immediately ping inside and out.

  I took a spare blade and tested by passage of 5.0 to 5.1 and 5.1 installation clean, the two producers same results. A host with two active network cards 5.0 (if static IP or DHCP) can ping inside and out. A host with two active network cards 5.1 (if static IP or DHCP) can not ping in our out. 5.1 host cannot obtain DHCP address, but fails to APIPA.

  I found the problem. For some reason, both switches must be actively connected on the same network for observed networks provide correct information for the collection.

• Configuration of the initial network for ESXi

  Hi all

  New VMware user here, set up my first environment. I have an ESXi host who has four physical network cards (NiC0, NiC1, NiC2, NiC3).

  I installed ESXi, the VCVA device and multiple virtual machines with great success. They are related to the local storage currently, but I want to connect to our iSCSI SAN.

  Physically NiC0 and NiC1 are connected to our regular network switch. NiC2 and NiC3 are connected to our iSCSI network, which is a separate network.

  So what I did is NiC0 and NiC1 set as active for the management on the ESXi host network. I left NiC2 and NiC3 uncontrolled.

  When I use the vSphere client to create the iSCSI connection, he can't see NiC2 or NiC3. I need to activate all four cards can use them in vSphere?

  If I enable NiC2, NiC3 and, they say that they are disconnected, because they are connected to our iSCSI network and have no regular network connection.

  Am I way off track here?

  Welcome to the community,

  I would recommend you take a look at the Documentation Centre of vSphere 5.1 to discover how to set up iSCSI software.

  You basically need to do is to remove the 2 NICs (vmnic2 and vmnic3) of the current vSwitch, create a new vSwitch with 2 groups of VMKernel ports and two vmnic and configure groups of ports to use a vmnic as active and the other as unused (i.e. port group--> vmnic2 active = 1, vmnic3 = unused and port group 2--> vmnic2 unused = vmnic3 = active). Once this is done, you can create the iSCSI map in "Storage adapters" and add two VMKernel ports.

  It is also important to review the documentation of storage vendors. Storage vendors usually provide the guide of best practices for how to configure iSCSI on ESXi to work best with their equipment.

• ProLiant ESXi management

  On psysical servers, we install the HP System Managment software which allows us to verify material etc..  We are trying to enable write caching on the remote server - allows us to be able to do with HP Array Configuration Utility.

  Is it still possible to ESXi, install the software on a virtual machine?  Or will we have to stop the server and boot from the CD to enable the write cache in the array Configuration utility?

  This is not possible through a virtual machine — a virtual machine has no direct access to the physical hardware of the host.

  There are two good methods to achieve what you are looking for:

  1. a fully supported: with the ACU Offline (i.e., take down the host), see http://v-front.blogspot.com/2012/01/hard-to-find-hp-tools-offline-array.html

  2. a not supported: by running the version Linux hpacucli in ESXi shell (without any host downtime!), see http://v-front.blogspot.com/2012/03/how-to-run-hp-online-acu-cli-for-linux.html

• Network with ESXi 4 VM problem

  Hello

  I have network problems with one of my ESXi 4. VMs I have two switches virtual, vSwitch0 and vSwitch1. vSwitch 0 contains the virtual network machine and the management network. I attributed to this network an IP address and I can connect to my ESXi host through the vSphere Client. vSwitch1 contains the VM Network 2 network and the virtual machine, I created on the host computer. This network will not respond to pings or Remote Desktop connections. If I connect to the virtual machine (Win2k8 R2), he cannot ping the default gateway or any other host on the network. I checked that all the IP addresses, gateways and DNS servers are correctly defined. If I put the host in the network of the VM, it responds to the pings and CdR - VM Network 2equals, no dice.

  Thanks for the help.

  Welcome to the community,

  from what you describe, is trying to replace the network cable or check the physical switch port settings (for example the access mode, spanning tree portfast,...)

• Remot ESXi management

  Hi guys I recently installed esxi 4.1 on one of my local machines is an everything works well except because I have a crap provider intrnet and router adsl netgear DG834PN trash I can't connect to my home network by simply using my external IP and I was wandering if anyone knew a system just such a (LogMeIn) where I can install in my rig esxi and be able to access and manage my Server from anywhere in the world

  You could set up a VM on the host, install the top vSphere Client, make sure that you can manage the host with it and then enable RDP on the virtual machine. Enable the port forwarding on your router to dlink (ie) to the IP address of the virtual machine and test... I also suggest using a service like (free) offerings of dyndns.com to use a normal url to connect to the installation of your home. Install their agent, or have your router put their list up-to-date, and you're good...

  I use the method of a vCenter Server RDP (on my ESXi host) in my lab at home environment. Enable port forwarding on my router Linksys (WRT610N) to the IP address of the Server vCenter when I think that I'll need to plug in the configuration of the House... Otherwise, I omit the port forwarding. I also use many of the services (now) of dnydns.com to make sure that my web and ftp servers are available to no matter what my audience/host IP address changes at...

  Establishing an AC DC to use for authentication, I suggest... Also use at least a password (you can use something like passutils.exe to check the strength of password) for this account and make sure that your network is secure also.

  I would NOT install anything on the host directly (not that you could under ESXi)...
