Question quick bonehead: ESXi management network?

Similar Questions

• Check the configuration of my management network please?

  I'm working on the settings described in this article of yellow brick, but I don't know that I was right;

  http://www.yellow-bricks.com/2011/03/22/ESXi-management-network-resiliency/

  I have two vmnic added to vswitch0, vmnic0, and vmnic10.

  

  I have this vswitch groups of two ports, one for vmk1 vmotion and the other for management vmk0.

  Tab grouping the vmotion port group NIC I specify vmnic10 as an active adapter and vmnic0 as before with backspace set to no.

  

  On the NIC teaming tab management port network group I do the opposite, vmnic10 is in standby and vmnic0 is active, but with BACKSPACE value again.

  

  Is it OK so far?

  What I am ultimately confused by vswitch NIC teaming tab configuration is two adapters program active since they are each active for a group of different ports this vswitch? and should restore the value not in this tab as well?

  

  Thanks for any help you can provide.

  The first thing I noticed: you use the same subnet for your management and vmotion traffic.

  Use VLANs and put on separate segments (vMotion traffic is not encryted).

• ESXi 5.5 - unable to connect to the management network

  I've been using ESXi for v3.  I have a small cluster of HP DL360 G5 where I was using ESXi 5.1 update 1.  I brought a new DL 360 G5 into the mix and decided to install 5.5.  After the installation, I'm going to set up the management network as usual and even after a reboot, I'm unable to access the site via http or the vSphere client.  For help, I installed the version of HP with CIM providers and I installed the stock VMware 5.5 with current pilot Rollup and they all exhibit the same behavior.  It starts fine, but I can't connect to the management network.  Curiously, however, they address IP does not respond to a ping.  I installed the 5.1 update 1 on the same server and it works fine.  Does anyone have an idea on what's going on?  Are there recommended troubleshooting steps?  It's strange to me because the ESXi has always been very reliable on HPs.

  Thank you - Greg

  Hi Greg,.

  Welcome to the community of VMware,

  To begin with, the latest version of ESXi, VMware supports the Proliant DL360 G5 has ESXi 5.0 U3.

• 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.

• ESXi 5 managing network not automatically start after reboot, or when the output of the mode standby

  vSphere 5.

  ESXi5.

  HI all 5 ESXi installed on HP BL460c G7. HP C7000 Enclouser system connected to the NAC (switch HP series A5800) via the Module HP FlexFabric 10 Gbs. The server has 6 vmcins:

  (1) management network - 2 NIC (1 GB per nic)

  (2) vMotion Network - 2 NIC (1 GB per nic)

  (3) Vitual Machine networks - 2 NIC (2 GB per nic)

  (4) zFCP - 2 network cards (6 GB per nic)

  After you restart or when the output of the mode standby, the management network starts does not automatically, you need to restart manually from the console directly. Hypervisor ISO downloaded directly from the vmware Download Center and all the recommended HP drivers downloaded and installed from HP Download Center.

  OK, another thing you could try is this change that HP recommended for my situation. The CLI performs: esxcfg-module - s "heap_max = 20971520" be2net

  and reboot. The memory default chunk size is not large enough and will change to this size in the next version of the driver.

  Also, have you tried yet 5.0 U1? There are a lot of bugs in U1.

• ESXi 5 Networking newbie question

  Hi all,

  I'm new to ESXi and I need some advice from experts on the network on the ESXi 5 host configuration.

  The installation program looks like this.

  A HP DL380 G7 server running 3 Server ESXi 5 company 2K8R2 VM, 4 LAN ports on the server, one dedicated to the management network.

  I want to set up the connection in the following way:

  Each VM should have access to the physical network, but I also want that all three VM will not communicate via physical network interfaces but by intra-Server network basically do not touch physical network for VM VM networks.

  If I understand correctly, networking in ESXi if I attribute same vSwitch to all virtual machines they will speak between them via intra network server, but then I'll be able to only affect that one LAN card physical to the vSwitch if my physical switch does not support teaming them and in this case I'm stuck at 1000 Mbit/s for a total throughput of all three VM?

  Then I thought to create three vSwitches, assign a physical LAN card to each vSwitch and each VM to his own vSwitch, but in this case each VM will communicate with each other through physical network right?

  Next idea was to do it the same way as previously mentioned, but also to create a vSwitch more without a physical NETWORK card assigned to it, connect all three of the computer as a virtual card on VM virtual LAN and have a different for this second network subnet and set up all services on all VM to communicate with each other through this (other) network. Then I would have a few problems with the resolution of name between VM if I reference VM by IP? Or maybe not because they are all in the same field of broadcast just to put another network adapter intra-host higher on the priority list in VM network settings physically map network related?

  Thanks for help.

  If you had 1 vSwitch with 2 exchanges, that traffic would be let through the network adapter.

  That's right if you have different VLANS on trade, but if they are the same then the traffic will also remain in the vSwitch.

  You can have several VMNIC (physical ports on the physical network card) connected to the same vSwitch without problems, even if your physical switch does not support grouping. Just leave politics to the default id 'port' of load balancing.

  So create a vSwitch, add vmnic as much as you like, and then connect your virtual machines to the vSwitch. Note that a single virtual machine will not be able to get more than 1 Gbps in flow, but the different virtual machines will span outgoing ports.

• 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.

• Circuits/server on the same subnet as the management network

  I'm having a difficult time for a virtual PC running on my server ESXi.  The IP address is on the same subnet as the management network statically assigned IP address.  The switch that is connected to the server port is trunking.  My question is, can devices on the same subnet as the management network?  If so, how do access you?  You have to create a new vSwitch for this?  Any help would be appreciated.  Thank you.

  Your portgroup for CUP7 is set to VLAN 1, while your progroup vmkernel port has no encapsulation VLAN defined.  Just change the portgroup to CUP7 to have no value in the box VLAN (its under settings for the portgroup).

• management network and vCenter

  Hello

  Should I put the vCenter on the same network as the hospitality of ESXi management?

  Now I have standard vSwitch0 configured with vmkernel port = vMotion vmkernel port = network management... im wondering if I should also create v vmnetwork for example the Mgmt network name as seen in the photo.

  

  I've never had problems, but I assume that from a security perspective, there is more to routed traffic otherwise on this subnet.  I have been a long time and never considered that it was essential.  In any way is ok, but I never ran on the management network and personally do not feel the need to put it out there.

  What happens if you have several subnets management? IE in my case that we have a different management of networks for some of our groups and therefore VCenter was impossible on both.  I'm surprised they put this in the documentation.

• Second NETWORK card takes over the management network

  I have a lab of dev ESXI 5.5 on a Dell PowerEdge 2950 with a dual port GbE NIC (Broadcom NetXtreme II BCM5708).

  My basic configuration was a port of configured NIC (vmnic0) with a switch (vSwitch0) Standard.  vSwitch0 was a group of Virtual Machine (for VMS) ports and a VMkernel Port (for the management network).  Everything worked well at this point.

  When I try to configure the second NIC (vmnic1) to a different network switch port and different to connect to iSCSI, network range vmnic1 took over the management network even if it does not show as being the management network.  After that, I'm more able to connect or ping the IP of vmnic0.

  When you configure the vmnic1, I added connection Type of VMkernel.  I did not choose to use the port for traffic management group.

  When I look at the console and choose to configure the management network I see only being vmnic0selected network adapter.

  Am I misunderstood the management network configuration?  If not, does anyone have a suggestion on what may be wrong or how I can diagnose?

  Thank you for your comments!

  I think I knew what was going on.

  I had my VMkernel for networking (192.168.2.0/24) in a different subnet to the VMkernel for iscsi link port (192.168.1.0/24).  The problem was due to the existence of a network trace unidirectional from 192.168.1.0/24 to 192.168.2.0/24 (but not in the opposite direction). As stated in the post of the blog below and elsewhere, if there are two VMkernels in networks with a direct route, the esxi host will be simply choose one of the VMkernels to act as the management network (no matter if only one of the VMkernels has active network management).

  I thought my networks did not have a direct route because of the impossibility (192.168.2.0/24) management network to communicate with the network of liaison port iscsi (192.168.1.0/24) but because the 192.168.1.0/24 network may route to 192.168.2.0/24, he made the two viable VMKernels to act as the point of view of the host management networks.

  After that I moved the post iscsi binding to a switch with no network route, my problem has been resolved.

  Re-reading the following is a blog post that helped me to understand my problem.

  Thanks to those who took the time to review and respond to my problem.

• Is it possible to stop the conversion through the management network?

  Our management 172.16.0.0/16 network and our production network 10.0.0.0/8

  When we try to make the P2V conversion, all traffic through the firewall that we use for routing between 2 networks, that really is not set up to deal with a lot of traffic and that is what is extremely slow conversion.

  Is it possible to get the converter to push this traffic through the network of production instead?

  the system is 3 ESXi hosts grouped in vcenter 5.5.  Is the storage on a San

  ESX expose NFC (network file copy) as a service that uses a converter to perform conversions and NFC uses the management network. As far as I know, it cannot be changed.

  There is one exception, if--if you do Linux P2V, cloning goes through the network of the virtual machine and you will not have this problem.

  I think you may have a more general with this configuration problem, as the NFC is used not only by the converter (for example, SRM, VMotion, etc...). See this: why vMotion uses the management rather than the network vMotion network?-frankdenneman.nl for something completely different, but which may sometimes cause a problem with this Setup.

• Management network NIC

  When I build my ESXi servers should I keep a separate management network NETWORK card like I did with the Service Console on ESX?

  Thank you

  Aaron

  About connectivity, the VMkernel port management is comparable to the Console's Service port. Just handle it the same way.

• Restart the console management network... affect guests?

  Hello

  I just wanted to be sure before we do anything. On my server ESXi, I have 2 network cards dedicated to the management of network and vMotion. 2. separate the interface network cards dedicated to guests. If I restart the network from the management console it will affect the virtual machines running on the host. I'm assuming that he used since they use different network adapters, but I wanted to be sure.

  Thank you.

  You're right, restart management network do not affect any computer virtual

• Unable to activate the management network...

  I'm new and VMWare VSphere and I tried to connect to a server with VSphere ESXi 4 but I kept getting hung up on the screen «Download tools to manage this host From...» ». I disabled the management network, hoping it would allow me to bypass the connection and enter the server, but he clung to the option 'download... Tools '. "the screen again, but this time with a 0.0.0.0 IP. I tried to activate the network again, but now I get the error, "Management Network Interface was not found". I don't know what this means and I'm having a devil of a time to discover.

  Hello

  The screen you see (yellow screen with 'download... Tools) is the screen of the ESXi server. to manage the ESXi server and the virtual machines installed on it, you need to connect to a windows box, navigate to the IP address (using a web browser) indicated on the yellow screen and then download the VSphere client tool, of course ensure your network working properly. The VSphere client tool will then connect to the ESXi and manage accordingl.

  Hope this helps

• Question of Duel ESXi servers

  All,

  I have an ESXi server that I am very satisfied.  I had to use a USB key and instructions from the internet to perform the boot and use (I've added the realtek on the USB network adapter).

  I have since bought a second computer to run ESXi also on.  Trying to boot the cd of ESXi, I came to the same conclusion that I had to use the USB.

  I made a copy of the image of the USB of the origin of a new USB ESXi server. -J' I then shut down the original server ESXi and started the new server.  Then, I've reconfigured the server network address and the name of management to be a new address/name.

  I bring them both and they boot and seem to run fine - however...

  When I connect to the CR I start getting errors. the client removes the connections and indicates that it is a mistake to talk to the server.  It seems that the 2 servers ESXi are contradictory.  If I stopped either server - errors disappear.

  Is there something I need to do to reset and be able to use my new second server?  (I already tried the reset on the server console)

  Thank you all
