• Loss of connectivity to storage device

  It seems that I get one of them at least once a day.  A few times the data store is unknown and other times told me the name of servers.  I have 4 servers in my cluster, all Dell and an EqualLogic iSCSI SAN.  I'm really at a loss about why it continues to be.

  Hi Chris:

  Make sure that you have configured according to the PDF attached things EQL. There have been some changes of VI3.5 regarding the iSCSI configuration and initiator software was completely re-written in vSphere. For example, multiple paths is a little different, and they recommend you actually have a vmkernel port for each physical NIC and that substitute you the failover parameters. You are or ESX servers can be remove connections that the volume rational access EQL moving to different Eth interfaces on the controller (just a thought). This is explained in the document.

  There is also a video cool tech that goes along with the document. http://www.EqualLogic.com/ResourceCenter/video.aspx?ID=8455

  Let me know if it helps!

• Loss of connectivity after cloning, or move a virtual machine, 4.1

  Nice day

  I have a cluster that contains the servers Fujitsu and Dell blades. The cluster has EVC. When I try to clone or move from one of the guests at one of the hosts Dell Fujitsu I lose network connectivity. The network cards are always present in the virtual machine, but I can't ping anything successfully. This happens on both CentOS 5.x, Windows Server 2003 and Windows Server 2008, I him have not tested on something else.

  What I did is to remove the network adapters and then add new ones. This example gets the machine virtual back up and running. However, this workaround solution does not bode well when the handle moving VMs DRS between these hosts and for any migration or cloning.

  I am not sure of the cause of this problem. My hope is to be able to move between the 2 different brands without having to reconfigure and restart each virtual computer.

  As I understand it, is that a problem in the loss of network connectivity for the VM created on ESX 3.5 or any virtual machine that also includes a new virtual machine created on ESX 4.1 with version 7 of material.

  If the VM is affected by this problem, then you may want to disable the switch Port security to check if this helps because once the virtual machine is migrated probably MAC address changes.

  If this problem occurs on virtual machines that were created on ESX 3.5 and then update the VMware tools, put off the virtual computer and upgrade the hardware to 7 version.

  Hope this helps

• Loss of connection WRT310N

  I have a WRT310N.  Every two days the router stops working.  Lights all blinking as they should, but nothing seems able to connect, for example, the computers connected wire and wireless nor can see each other or the internet (via cable modem).  If I power cycle the router, everything works fine, but can last only a few hours or days before lock up again.  I've updated the latest firmware, but no improvement.  Have I not wonky router or is there something else I can do to make this work always?  Any help would be appreciated.

  After any Firmware Upgrade, you must reset your default router and then re - set... If you have not handed over the router after the last update you must reset it now...

  Press and hold the button of reset for 45 seconds... Release the reset button... Unplug the power cable from your router, wait 45 seconds and reconnect the power cable... Now re - configure your router...

  If you are still having the same problem, you have to take out of the equation linksys router and connect your modem directly to a computer, see if it disconnects regularly... If it disconnects then it is a modem problem, if the connection is stable, then it's your router...

• Problem of PIX - loss of connectivity

  We are expeiencing that a very strange problem and any ideas would be appreciated. Here's the scenario, then I will describe the problem.

  Store #1

  Computer = 192.168.4.11 XP connects to

  ADTRAN router = 192.168.4.1 connects to

  SBC 64 k frame

  Ministry of the Interior WAN router = 192.168.0.1 with a gateway of last resort = 192.168.0.90

  which is the address of the pix that sends all internet traffic to the 64.x.x.x (external) address

  All the store suddenly can not access the internet. However, it can access other shops and HO without any problem. When I try to make a ping or use IE at the store, it resolves the address, but a few times out.

  In the pix, there is the following line to take all internet traffic in the stores and will forward it to the external side of the pix and on the internet

  Route 192.168.0.0 255.255.0.0 64.x.x.x 1

  As I said this has worked fine until today. We are at a loss.

  Help, please!

  Let's see if we can help you.

  The declaration of the route that you have shared with us doesn't seem right.

  Most likely, your itinerary records should look like this:

  route 0.0.0.0 0.0.0.0 64.x.x.x 1<--- tells="" the="" pix="" to="" use="" the="" outside="" network="" as="" gateway="" of="" last="">

  Route 192.168.4.0 255.255.255.0 192.168.0.1<--- tells="" the="" pix="" that="" the="" 192.168.4.0="" exists="" on="" the="" inside="">

  Does make sense?

  You would have additional road statements for other internal networks pointing a device inside like 192.168.0.1 router WAN HO for the Pix knows how to route packets to them.

  Maybe you can share with us the statement "see the road" so we can help you determine if this is indeed the cause.

  Thank you

• Loss of connectivity after reboot B200M4/ESXi6

  I've been hitting my head against the wall for long enough, so I hope someone can shed some light on where things have gone so badly.

  I recently deployed a UCS environment consisting of the following:

  • 5108 w / blades M4 5xB200
  • 2 x 6248 (2.2 (5A))
  • EMC is 5200 (directly connected iSCSI)
  • vSphere to 6u1
  • • ESXi (custom image Cisco) 6u1a with the patch KB2137546 and enic 2.1.2.71

  The FIs uplink to a pair of 3850 s (bunk).

  The hosts and the virtual machines have been intermittent connectivity problems and poor performance.  Constantly, if I reboot the host, ESXi management connectivity is lost until I have reset within ESXi management network.

  On the side of vSphere, I have a pair of vmnic on the management, but also the other production VLAN VLAN and a pair of vmnic for iSCSI.  A standard vSwitch for traffic MGMT and production (aggregation based on the Port ID) and a second standard vSwitch for iSCSI (no grouping) traffic.

  I tried a number of things to troubleshoot and resolve the problem. Recently, I discovered the crucial question with 2.2(5a) and performance on the B200 M4 blades.  I upgraded the software to 2.2(5b) this past weekend with no resolution.

  At this point, if I reboot a host with two vmnic on the vSwitch. Mgmt, the host will have NO connectivity Mgmt.  If I reset the management network, it responds to the pings.  If I remove a vmnic and a reboot, just restarts happy, albeit without redundancy.

  If I let the two vmnic on the vSwitch Mgmt & reboot, no connectivity.  But if I disable one of the network adapters in the UCS Manager, he starts to respond to pings.  As soon as I re - activate the NETWORK card in UCSM, pings are deleted.

  So I am at a loss.  Any idea?  Thank you

  Greetings.

  Looks like you can hit https://tools.cisco.com/bugsearch/bug/CSCuv00089/?reffering_site=dumpcr

  You can open a tac case to confirm.  If this is the problem, then an upgrade on 2.25 c or more is resolved.

• Loss of connectivity to NAS

  I have a NAS device to the network called gigabit-nas.  I've been successfully of all systems on the network for four years access.  Last week it was no longer appear in Network Explorer on all systems.  It's like the DNS does not work.   The device could still be crazy and you can connect to it by using its IP address.

  Using the term //192.168.0.103 or \\gigabit-nas it appears in only one instance of the Explorer, but not when you open it again.  I went through each of the troubleshooting procedures listed in the Forum of the community @ http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/keep-losing-conectivity-dns-not-working-pc/df840a74-004a-4be7-a399-a0e9af6b18bf

  I also installed and run the Nnap utility, and it shows the port 445 for file share to be opened.

• PIX 501 PPPoE w / static NAT loss of connectivity

  I have a {should} installation very simple. PIX 501 with PPPoE on the external interface, 3 inside customers using PAT and 1 inside the client I am trying to use an address mapping static on permit communications with this host from the outside using a particular service. I did a lot of these before where there was an ADSL router in front of the PIX, but this is the first where I've used the PIX as the PPPoE client. When I use the static NAT for the single host it loses all connectivity beyond the PIX outside interface. When I get rid of the static mapping, through PAT very well. I spent many hours troubleshooting and control a lot of obvious things, but I am at a loss right now... unless it could be a problem with the IP address that has been assigned by the ISP for use with static NAT. Any thoughts on this would be greatly appreciated.

  Thank you

  Sorry, in your case that static would look like this because of the dynamic IP.

• Loss of connection to hosts on 1 of 2 switches disconnect pregnant?

  Hello

  Hoping someone can help point me in the right direction for this problem.

  We have three hosts IBM HS23 our cluster parameters, these hosts all sitting in the same Chamber and pregnant said has 2 switches Cisco 3110 in the back. These switches are configured with trunks etherchannel to our switch kernel stack and transport 10 + VLAN on the trunk. These VLANs are configured as port groups under a single standard switch on each host and guest virtual machines are placed in the VLAN relevant and can communicate on the network.

  The problem is that yesterday I temporarily unplugged cables etherchannel on the second Cisco 3110 to the back of the speaker and we have lost the connection to 2 of the 3 hosts of base, connected cables back in and connectivity has been restored. I then disconnected the cables connecting the other Cisco 3110 and we lost connectivity to the remaining host.

  I was under the impression that, as the two available on each host vmnic are active adapters for each group of standard switch ports that we had the resilience of the system by which we could lose a Cisco 3110 and maintain connectivity.

  This isn't the case, but looking at the config I do not see why.

  Someone at - it advice on where I need to be in the research or experienced something similar?

  Thank you

  ESXi hosts are connected to the ports of the two internal switch Cisco switches and unless you have configured tracking the State of affairs on the Cisco switches (i.e. If the uplink ports are down, the downlink ports will be closed), ESXi hosts will still see that their internal ports of Cisco online and therefore fail over to the other switch.

• MainStage - loss of connectivity environment performance

  Hi guys,.

  I seem to lose connectivity between my midi controller (m-audio code 61) and Mainstage environment performance. I lost sound and the warning message on the Mainstage saying that the midi controller is no longer available. Currently, I connect via the USB port, which also fuels the midi controller. I have to disconnect and reconnect the USB cable on the midi controller or laptop and then it seems to work again. Any ideas on how to solve this problem?

  Try another USB cable. A premium quality cable may be the solution. The connectors tend to have a tighter fit. Another alternative is to use a power supply and a USB MIDI cable, or connect via a cable to your audio interface MIDI, if it has a MIDI.

• Loss of connection wifi on iPhone and iPad Mini

  A recent issue, it's that I keep losing wifi connection at the same time on my iPhone and iPad Mini, but not on my MacBook Pro.  All three are in the same room with Time Machine and SB 6141 modem.  Any suggestions?

  Is the unstable WiFi other places too? IOW if you go to a coffee - can the iDevices contain a wifi connection?
