SG 300-28: duplication of port: loses the network connectivity of the destination host

• vMotion fails at 9% - Source host cannot connect to the destination host

  Hello

  I wonder if someone could shine any light on why vmotion fails to occur between an ESXi host who has just been restarted, in order to test HA. I have the following configuration:

  3 x ESXi5 DL360 G7s with two 4-way NIC

  VSphere Vcenter 5

  1 x cluster configured for DRS HA

  2 x Procurve 2910 - 24G

  The switches are not connected to each other.

  Both switches are configured as such:

  

  All ports are not marked. NO PLEASE, no routing

  Each host vMotion vSwitch is connected to two switches by 1 x 1 GB nic

  I configured a vswitch on each host of vMotion. There are two ports vmkernel with two IPS on the same subnet. There are two vmnic attached to the vSwitch. On each port, a Vmic is configured to be active while the other is unused. I enabled frames on the vSwitch and 2910 switches. A VLAN has been configured on the two predisposees 2910 for vmotion with frames and defined traffic on "no label". I can successfully vmkping all the ip s vmotion on all ESXi hosts. However, when I test HA by stopping an ESXi host, when I restart the ESXi host I am unable to vmotion in that ESXi host. When I test vmkping I find that the host rebooted can only vmkping itself and no other host can vmkping it. Vmotion attempt fails on 9% and errors with the source host cannot connect to the destination host. If I restart the two switches of 2910 I can then perform a vMotion and the vmkping is a success.

  Help, please?

  Thank you

  I have since read up on the various load balancing options and find that your method is preferable during the method of "ip hash.

  I'll make the change to "port based" and link the two switches

  Hello Simon, I think it's a good option to do, since the hash IP load balancing is a bit special and really requires both interfaces to connect to the same physical switch, which must also have a specific configuration. If you like the results after the new changes.

• Cannot migrate VM between 5.5 ESXi versions: the version of the product to the destination host does not support one or several CPU features

  We receive an error message that I am trying to make sense. I understand very well the notion of compatibility, CPU, CPUID, masking and so on, after working on a competitor hypervisor. However, this error seems wrong (or needs better wording) based on my understanding:

  Here is the message:

  ----

  A general error occurred: the version of the product to the destination host does not support one or several features of the CPU currently use by the virtual machine.

  Characteristics of CPUID level 0 x 1 'ecx' register are indicated with a '1' bit: x00x:xxx0:xx0x:x 000: x 0 11xx:00: 00xx:11xx

  ----

  
  

  This happened during the migration between two hosts ESXi with the same physical processors - in this case, a Westmere X 5650.

  
  

  The source host is on ESXi build 2068190 (5.5). The destination host is on ESXi build 1474528.

  
  

  The bits it seems to complain are:

  
  

  DTES64

  Monitor/MWait

  Cx16

  PDCM

  The punch line seems to be: "the product version of the destination host. However, I have trouble believing that support for these features have been added to ESXi between the two versions. If it were, VMware has been certainly silent about.

  For what it's worth, explicitly set us the CPUID masks in our virtual machines (no, CVS is not an option for us at this time.) This is the mask:

  CPUID.1.EAX = "00000000000000100000011001010001".

  CPUID.1.ECX = "00000010100110001110001000111111".

  CPUID.1.EDX = "10001111111010111111101111111111".

  CPUID.80000001.ECX = "00000000000000000000000000000001.

  CPUID.80000001.EDX = "00101000000100000000100000000000".

  cpuid.d.EAX = "00000000000000000000000000000000".

  cpuid.d.ECX = "00000000000000000000000000000000".

  cpuid.d.EDX = "00000000000000000000000000000000".

  Note that the bits of the message complains (2, 3, 14, 15) * are * in fact forced to '1' in our mask of cpuid.1.ecx. That means (if I understand correctly), ESXi does not have the virtual machine unless the host processor supports the feature. And in our case, the virtual machine will start with happiness on nodes, with both versions. It will be not simply migrate between them.

  So, long story short, is this a bug of ESXi? The error message is misleading? I understand something?

  Thank you

  To use the masks feature VM in this way, you must replace all the 1 to your masks with-'s:

  CPUID.1.EAX = "00000000000000-000000 - 00-0 - 000-

  CPUID.1.ECX = "000000-0-00--000---000-000---".

  CPUID.1.EDX = '-000 - 0-0 - 0-

  CPUID.80000001.ECX = "0000000000000000000000000000000 -"

  CPUID.80000001.EDX = "00-0-000000-00000000-00000000000.

  cpuid.d.EAX = "00000000000000000000000000000000".

  cpuid.d.ECX = "00000000000000000000000000000000".

  cpuid.d.EDX = "00000000000000000000000000000000".

  Zeros erases the features that are not available on your hosts Westmere, and dashes will leave the other one features.  The problem with those masks was forced to you certain features on who would have normally been off.

• Satellite L550-1XC - lose my network connection

  I recently bought a Satellite L550-1XC running under Windows 7 64-bit. I have a D-link router and two XP machines based on wireless links all very stable. I have connected the Toshiba very easily and he finds the network and the Internet quite easily.

  My problem is that the Toshiba randomly loses the network to another PC and printers that are shared on a desktop computer but never loses its Internet connection.

  Refresh the network tab can't find the network and it can be 30 or 40 minutes before it will reconnect to the other PC on the network when updating. The signal strength is excellent and the Toshiba can see that several other networks clearly at much lower, neighbouring and other levels. It's very frustrating, reboots do not seem to releive the problem.

  Welcome signs because it is driving me crazy. What about Peter

  Hi, Peter D,.

  Have you tried updating the driver WLAN? Usually if you always lose the WIFI connection you should try to update this driver. It should work

  You can download from the Toshiba WLAN Portal:

• Once a day, I lose all network connectivity on my Windows XP SP3 laptop. When I try to ping something I get this error: "PING failed, error 1450' code"

  Hello, those in about 3 days, I lose network connectivity on my laptop with Windows XP SP3. When I ping no matter what page of the console I get the following error message: show PING failed, error code 1450. I tried to use the option of repair in my area, but it did not help. Computer restart resolves the problem, but I'd like to avoid doing. What should I do to solve the problem?

  original title: loss of network connectivity

  Since this happen in two different ISP, try to reset your modem or router and also contact your ISP support. Some ISPS will set a rule and limitation of their user, but in your case, discuss it with your ISP, or contact technical support for your PC manufacturer.

• Continuous wireless network adapter lose its network connection

  It used to work very well in the beginning, but after a many windows updates, my laptop has started to lose the Wi - Fi connection every several minutes.

  Windows troubleshooting utility usually fixes the problem of reset wireless network card. Sometimes, however, it does not set it up that I restart the PC.

  ... I suggest you to update BIOS, chipset and wireless network drivers these links and check if it helps...

  Hi, Yann,

  I updated the driver, but it did not help. Update the chipset has probably not because I have AMD (the update says that I don't have the required devices). BIOS has been updated some time (I have the latest).

  I also searched other topics and did the following:

  Disabled IP assistance service;

  Value another configurtion IP: manual and entered a fixed IP address and the default gateway.

  Turned off the Windows Firewall for this network.

  The problem seems went, at least for now, although I don't know what stage did.

• HP1102w continues to lose the network SSID

  My Laserjet 1102w wireless worked fine for about a year.  Now he has started to lose my network connection.  When I print a status page, it shows that it is "connected" to SSID HP8AA7DC, which I assume is the default value of HP, and had no IP address.  I re-installed the printer 3 times in 4 days and it works fine for a day, then the same thing happens.  I am running Windows 7.  To my knowledge, nothing has changed recently other than to have an extra laptop using the network (never printed however).  This could be the cause?

  OK, thanks for that.  We will set an IP address of the printer:

  -Print a the front of the printer Network Setup Page. Note the IP address of the printer.
  -Enter the IP address in a browser to reveal the internal settings of the printer.
  -Choose the network tab, then wireless along the left side, then on the IPv4 tab.
  -On this screen, you want to set a manual IP address.  Set the IP Address of the printer to the same as its IP address but replace the latest figures with "250".
  -Apply the subnet 255.255.255.0 (unless you know it's different, if so, use it)
  -Enter the IP of your router (on the Page of the Network Config) for the gateway.
  -Enter for the first DNS 8.8.8.8 and 8.8.4.4 for second DNS. It's Google DNS. You can choose a different external DNS if you wish.
  -Click 'apply '.

  Now, stop the router and printer, start the router, wait, and then start printing.

  After that, you will have to redo 'Add printer' using the new IP address.

• Are thinking of duplication of table to the replication of Vsphere, a quick question

  We currently use Array replication and plan to use the replication of vsphere for flexibility. Unfortunately, we have more than 500 virtual machines to protect - but it is another question and I hope MRS. deploy several devices that will help.

  I can't determine which network interface, the replication traffic goes on:

  1 Hypervizor ports between the ESX hosts (which are 1Gbit in my case) where VMS are?

  2. pushed through vcenter somehow?

  3 Vlan than VR devices are connected to the?

  I have a 10 Gbps link between sites, trying to find how to use more than 1 GB, because the 3 options above are 1Gbit. Although the unit sat on a group of ports that is supported by the host ESX 10Gbit links - but I guess that the only real device of a 1Gbit NIC adapter.

  Hello

  Replication traffic is going:

  1 VR source ESXi server at the remote site via custom protocol LWD (light-weight-delta) TCP ports 31031 and 44046.

  2. outside in VR server via port 902 device and Protocol NFC ESXi host target, then the target data store.

  Separate NICS for VR (isolation of network traffic) replication traffic - to GDL from source ESXi to GDL for server VR application and for inbound replication traffic target ESXi NFC are not available in the current versions, but are part of an RV to come free.

  The VR machine using a NIC vmxnet3

  For the current version, you might want to perform some custom routing/formatting via the ports 31031 (initial full synchronization) and 44046 (all the traffic from replication after the initial synchronization is complete).

  Kind regards

• Apple TV loses network connection

  Why my Apple TV loses its network connection? Each article I found said it's your network... It is not my network. I have 4 other Apple TV on my network of 5 ghz and they work great. I've seen articles that say it is the signal of my AirPort Extreme. It is not the case... As I said previously I have 4 other Apple TV scattered throughout the House and Apple TV that has the problem is sitting right next to the AirPort Extreme. All 5 Apple TV are Gen 3 and the updated version. So is there anything else I can try before buying a new Apple TV?

  Other devices work does not have a network problem.

  You can get a report ffrom istumbler, netstumbler or similar to see a current state of the network. This will give you the strength of the precise signal, noise, networks nearby. With the help of Ethernet will also check. You can also test it on another network

• In loose wireless network connection once the last update of definition for Windows Defender - KB915597 is installed.

  Hello.
  The problem I've been is that I lose my network connection to my wireless network when windows downloads and installs the latest update of Windows Defender (definition 1.55.1119.0).
  It can detect the network and others nearby, but cannot and does not connect to my network.
  The only way I can solve the problem is to do a system restore to an hour before the update was installed and disable automatic updates.

  I have a HP Pavilion dv9000 running Windows Vista Home Premium.

  Thanks for any help.

  Did you check the setting on you, defender of the window or the firewall settings? These things will be pervent you to connect some time. I suggest that you try disabling Windows Defender and try to connect to the internet. Useful to try link: http://support.microsoft.com/kb/918355

• In vMotion which files moves the destination ESX host?

  VMware dear Experts,

  Virtual computer on a shared storage shops, while moving the virtual machine from one ESX host to another, I want to know that VM all files are moved to the destination host ESX, once the vmotioned process is complete.

  Concerning

  Mr. VMware.

  Some files are moved with vmotion - the content of the memory VM is moved from an ESXi host to another - the files do not change. If you are talking about storage vmotion where the files that make up a virtual machine are moved to another data store while the VM is running - the VMDK files are copied first.

• Re: Satellite L670 loses the wireless connection

  Hello

  I have a Satellite L670 - 1 H 1, a new laptop that runs Windows 7, with all the drivers and software uptodate, including the wireless card.

  I have a BT Home Hub 3 with an Edimax EW 7416APN v2 300 m range extender to help boost the signal in the kitchen area.

  The laptop works fine when I stay in the room where the reception centre. If I move in the kitchen the laptop will usually lose the wireless connection after a few minutes and I cannot get it back unless I turn the LAPTOP works and return to the Home Hub.

  I see no obvious reason to this problem. Two other laptop computers used in the home, more a smartphone stay connected with full signal in every corner of the House, at any time.

  I have to use the range extender, but is it possible that the laptop Toshiba just don't hear well with it?

  Any advice would be welcome.

  Thank you
  Canton

  Hello Canton

  As you know quality of connection WLAN depends on different factors is not easy to say why you have this problem, WLAN. I use Toshiba laptops for a long time now and I didn't notice in the past some serious question of WLAN.
  For example I'm 4 router with standard g and have very good signal even in the cellar too or out in the back yard.

  If possible, try to test the WLAN connection elsewhere. Maybe your friends have WLAN routers so you can test it.

  You have a new router or old?
  What WLAN standard do you use (b/g/n)?

• HP LaserJet M1522nf begins to lose the network connection

  Hello! I have HP LaserJet M1522nf and I use it for about 1 year maybe, but since last week, he begins to lose the network connection (ping failed, web interface does not work too). To be correct, the printer is connected directly to the network through an ethernet cable, and the cable is perfectly fine. His work when you turn it on and for the next 5 to 15 minutes, but after that it lost connection (tasks start fails).

  I really like using little aid, some perhaps of advice. Any suggestions?

  Hard reset the router to factory settings and reconfigure your settings.  Pass the cable to a different port on the router.  You said that the cable was good... change anyway.  Try now.
