ESXi 4.1 and Virtual Connect (Flex 10): no network statistics

• HP BL490C G6 / NC553M / Virtual Connect Flex-10 / frames not subproject

  Hello world

  So, we are adding some additional 5.5 ESXi hosts in our cluster.  Host hardware configuration looks like this:

  * BL490C G6

  * Dual Proc

  * 72-144 GB of RAM

  * Integrated NC531i NIC

  * Other NC553M NIC

  Inside the enclosure, we have four Flex-10 modules to provide connectivity to the NETWORK adapter as well as the NIC NC553M to the location of mezz 1.  The reason for the card NETWORK NC553M is it is supported of the extended 9K frames.  The NC531i has only 4K support frame.  It's the exact configuration for a G6 blade in the HP cookbook on page 10 of the http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c02533991-10.pdf

  On the side of Virtual Connect I have four modules stacked with cables SFP - DAC 10 m 1 GB to provide connectivity and then we have a shared connection fixed module 1 and module 2 for the power switch in this cage to 10 GB so.  On the kernel to miss, we made sure to allow frames jumbo on iSCSI VLANS.

  I made sure my vSwitch and adapter MTU are all set to 9000.

  

  

  

  The problem is that I can not vmkping with everything above a size of the iSCSI standard package VLAN without having too much attention when I say do not fragment.  As you can see from downstairs than a normal ping works fine, but if I try something like a 2K ping fails.

  

  The switch that he speaks is HP Procurve 5400ZL R2.  I configured a port of 1 GB on the untagged for the iSCSI switch VLAN and I had no problem by assigning an IP address of my computer windows laptop, allowing 9 K jumbo frames and the realization of pings jumbo frame network SAN.  So, that tells me that the switch on the side of SAN seems good.

  So what in the world could cause this problem?  Some things roll around in my head are:

  • Configure another blade of VMWare inside the chassis configured the same way as this one.  See if I can vmkping of frames to the other blades VMWare iSCSI NIC if it works then it would tell me that jumbo frames work inside VMWare and inside the virtual environment itself connect C7000.  They swear in all Virtual Connect documentation that frames "turned on by default".  I would like to find a way to confirm that on the CLI or something.
  • Configure a dedicated connection for iSCSI traffic on the Flex-10 modules to iSCSI VLANS.  Do not use a shared set of uplink.  This shouldn't be a problem though.  This is the scenario 2 of the HP Virtual Connect iSCSI Cookbook
  • Configure another slide with the same material, but something as CentOS load on it and see if he can make this map jumbo frames and the network.  If it can and can not VMWare then he would tell me something wrong with my configuration of VMWare

  I would really appreciate anyone who helps to solve this problem of configuration.  We really need get this cluster running inside this frame so that we can continue with a migration project.

  Sincerely,

  Jonathan

  I have seen that sometimes a host needs a real reboot after enabling jumbo frames, did you do that?

  'Too long message' error comes from the IP stack own hosts and not a peripheral network between the two, your package is never leaving the host.

  Make sure to specify the interface vmkernel dating the -I spend when you run vmkping:

  1. you can vmkping the host on his own localhost and vmkernel interface IP? For example:

  # vmkping d s 8972 127.0.0.1

  # vmkping - I vmk1 d s 2000 [Destination IP]

  2. try tests with esxcli network, diag ping utility for example:

  # esxcli network of diag ping - df - vmk1 - the ipv4 interface - size 2000 - host [IP of Destination]

  3. your iSCSI network is on a completely different subnet of all other interfaces vmkernel (e.g. Management), and it is a flat area not routed layer 2, right?

  4. always make sure that your card drivers NETWORK and firmware are up to date.

  5. the output of the following commands could be useful as well, if you replace information such as IPs please do so in a consistent way to keep relationships intact:

  List of the nic # esxcli network

  # esxcli network ip interface list

  get # esxcli ip interface ipv4 network

  list of ipv4 route # esxcli ip network

  vmware # esxcli network vswitch dvs list

  list standard # esxcli vswitch network

  List of the nic # esxcli network | awk (' print $1' "). grep vmnic | while reading nic; make esxcli network nic get - n '$nic '; fact

  # vmware - v

• 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.

• ESXi 4 hosts and virtual machines with domains and different IP addresses

  Hello, I hope someone can shed some light on this problem.

  I have an ESXi host.  It is in the 'AREA A' and has an IP address like 204.75.225.6.

  Is it possible to use the tool VMware P2V Converter some servers that are located in one field other than ESXi host and have different IP addresses?

  Example: VM candidate: in "AREA B" with IP address 192.168.1.56.

  Both domains trust each other.

  Y at - it a tip to configure the network settings on the host to allow that?

  I currently have 2 vSwitches.  One for the management network and the other is for the traffic of the virtual machine.

  Firewall?

• DNS domain and the connection to the AC network

  I'm new to this so forgive me.

  We are upgrading the workgroup to active directory.

  We have defined the high field and connected a laptop computer to the domain. As part of this exercise, it must configure the DNS.

  A laptop that is connected to the work area (wired / wireless) works very well. The problem occurs when the laptop of the said is removed from the network and connected to another network (wireless home for example). This laptop can now access the internet because it has the IP address of the DNS server configured on the Properties tab.

  Is there a way to turn it? Currently, it takes the Group of 'network configuration operator' enabled on each user account, so they can manually reconfigure the DNS which is something we want to avoid!

  Other useful info or not?

• OfficeJet 6600 connects to the wifi network

  Hello

  I bought an Officejet 6600 and effortlessly connected to my wifi network, print and scan for a day. And there are two days that he stopped conntecting to the wifi network. In the meantime, our router turned off and turned back on. That's the only difference.

  First of all, the printer would not even detect the wifi network. I solved that by changing the configuration of the router (Cisco 3925 EPC) and passed under the Setup wireless "Wi - Fi protected setup" to "manual". I can now see the network on the printer again.

  But after that I've selected my wifi network and enter the WPA password, the printer tells me that the network connection is impossible. I printed a page of diagnosis, which told me that the problem is perhaps related to the MAC filter. But I have no MAC filters. I also tried to pass of WPA/WPA2 to WPA only, but that doesn't change anything.

  I also tried to set the mode wireless via the USB cable, but no avail. Everything seems to work, until the moment when he tries to connect to the wifi (screen with 'configuration' with the large antenna and pulses of radio waves).

  Should I give up and bring it to the store? I'm getting desperate!

  Thanks for your help in advance,

  Raphaël

  OK, to make sure I understand - the printer connects effectively to your wireless network, and well it works for a while once the printer goes to sleep, your computer or router may not wake.

  If this is the case there are a few things that we can try:

  1. in the settings of your router, make sure that the multicast is enabled.

  2. set the 2.4 GHz router to 11 channels.  I know it sounds weird, but please try.

  3. 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. You must assign an IP address outside the range that the router sets automatically (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') 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.

• ESXi and virtual machine CPU cores

  The question I would ask is the ESXi processor cores and relationship of the virtual machine CPU. Is it recommended to assign some carrots to VM (this is assuming that the VM needs CPU extra for reasons of performance)? We will use the following example. If the host ESXi lies the VM has 40 cores of the processor is recommended to assign carrots in 2, 4, 8 format to the virtual machine? And that's okay assign 6 since 40 is not divisible by 6.

  jrmunday: when it comes to carrots vs sockets, they are there for purpioses licenses, other than one vcpu is a vcpu

  soda: each kernel is a vcpu, so you should not worry of the underlying hardware and the divisibbility... It is not a mathematical formula to be used on the basis of underlying archatecture. the only reason underlying archatecutre would be important is VCA differences, not the underlying differences.

• ESXi and Virtual Center

  Hello

  I am currently running esx 3.5 and VC 2.5.

  I have a lot of spare equipment (thanks to VMware ) and had the idea to install esxi use local storage on some of them and use them for testing.

  (1) can import these boxes esxi in my esx virtual center server to manage (is not part of my clusters) and no intendion HA DRS Vmotion etc and therefore still free licience or do I need a licience esxi VC?

  (2) what I could use to migrate mailboxes to existing test of esx with SAN to my local storage under esxi, converter Enterprise Edition or just simply copy and paste on the network?

  Thanks in advance

  Joe

  Don't forget to backup EVERYTHING before you change anything

  (1) manage ESXi boxes requires additional licenses for VC agent on them, you can't do this with the free version.

  (2) converter would be the simplest solution (Standalone v4 is now available, for free, no more distinction between free/enterprise)

• VM Compatibility ESXi 5.1 and later bad (VM version 9) with the network

  I'm having and ESXi host with 10 VM, all connected to the same portgroup on the virtual switch. To allow THT, I created the last slots with 5.1 ESXi compatibility and later (VM version 9), where all the other machines have ESXi 4.x and later (VM 7).

  Now, I'm having the issue 2 machines with version 9 can talk to each other, and version 7 cannot talk to each other. It is not possible to make a ping to a version 7 virtual machine vm version 9 and vice versa.

  
  

  An idea, a re there known issues, something I did wrong? From what I saw that day was to be a major change in the networking between these versions.

  Any help welcomed verrrrrry!

  Thank you, Philippe

  
  

  
  

  OK, after spending a day debugging, convert machines front and rear, delete and remove the NETWORK card I was able to convince the administrator to restart the host ESX - problem solved!
