• Error adding array manager - VSphere 4, 4 SRM and Dell Equallogic

  I have built a new VSphere 4 of 2003 server and that you have installed SRM on it with one of Dell Equallogic SAN.  I'm point table configuration manager.  After I enter the information, then click on connect, I get the following error:

  Error occurred: XML Document is Empty

  I tried to run the installer with the repair option again and removed and added the SRA with no luck.

  Any help is appreciated.

  Just treat it today.  The plugin storage Dell is written in Java, so your Java executable needs to be in the path.  RDP on your SRM server and open a commandprompt.  If you can not simply run "Java.exe", you will have this problem.

  I just do a fresh install of the latest Sun JRE and then it worked fine.

• VSphere 4.1 and Dell MD3000i iSCSI raid firmware version

  We had a problem to upgrade to one of our VMservers last week to version 4.1, seems that the version of firmware for the Dell San iSCSI raid is not compatible, and our Server 4.1 is not able to see the SAN.  Anyone encountered this?  Does anyone know if Dell has yet released a version update of the firmware?

  Thanks, Tandrist

  GEN 1 vs. Gen 2 is not a material difference, it's the firmware (vs 7.x 6.x).  At any given time a few years back, they decided that the firmware that they created was too buggy to fix and they scrapped it and started over.  All units purchased in the last two years must have been shipped with firmware Gen 2 and if you have an older one, it is easily (but slowly) being upgraded.

  My system is running 07.35.22.61 and it works fine.

  EDIT: Have you checked that the name of the iSCSI initiator has not changed during the upgrade?  Don't forget, the Bay Dell determines what LUN to show you the way in which the customer is identified.

• with vSphere and Dell MD3000i iSCSI design

  I installed a server ESX 4 (the first of three for this cluster), and a SAN Dell MD3000i iSCSI connected through two switches Dell PowerConnect 2816.

  Now I read the VMware 'iSCSI SAN configuration guide', and I wanted to just make sure I did the design correcly.

  I have connected a Teddy ESX (vmnic1) to one of the pSwitch and another (vmnic5) in the second. This pSwitch SAN iSCSI ports are connected, so that one of the switches carry the 10.10.10.x subnet and the other the 10.10.11.x (see IP plan below)

  The two natachasery have a vSwitch each (a do not share), a portgroup each and are configured on different subnets, IP (see attached screenshot)

  Plan of intellectual property:

  Port iSCSI-10 group (VMkernel): 10.10.10.1

  Port group iSCSI-11 (VMkernel): 10.10.11.1

  0-0 SAN controller: 10.10.10.10

  SAN 0-1 controller: 10.10.11.10

  Controller 1-0 San: 10.10.10.11

  SAN 1-1 controller: 10.10.11.11

  By using this configuration, I could see four different paths for each LUN. and I was able to make the ESX Server will switch to different switches/controllers as I unplug the vmnic1 network cables and vmnic5, one at a time.

  Then I found the section on 'esxcli' configuration guide and multipathing configuration, which I carried out in accordance with the instructions ("esxcli swiscsi nic add - n vmk0 d vmhba34" and "esxcli swiscsi nic add - n vmk1 vmhba34 d ')

  Now I have eight different paths for each logic unit number, three of whom are 'Active' and an 'active (i/o)' (see my screen attached the capture).

  So, my questions are:

  1. the eight paths to each LUN really normal in designs of iSCSI?

  2. is my vSwitch/Teddy/pSwitch correct design choices?

  Thanks in advance!

  / Anders

  @hennish,

  As long as your new design continues to meet your needs of failover and workload, your infrastructure design should be fine.

  But you might want to take a look at this design Dell. In particular, step 12 that configures multiple paths in round-robin policy using the VI GUI client, for

  Each LUN exposed to the ESX Server. This allows balancing on two

  Active paths to the LUN. After completing this step, you should see2 "IO Active" paths.

  Kind regards

• VMware vsphere essentials more and Dell MD3000i iSCSI - virtual disk not on preferred path

  Hello world

  I am trying to set up our new vmware vsphere essentials plus the facility. We have 2 x Dell R710 servers running vmware esx4 and have a md3000i SAN.

  Each server has a network cable to connect to a network SAN controller.

  vmserver1 a vmnic6 IP 192.168.130.110 the IP controller connection 0 192.168.130.101

  vmserver1 has IP 192.168.130.111 vmnic4 connection to controller 1 IP 192.168.130.102

  vmserver2 a vmnic 6 IP 192.168.131.110 the IP controller connection 0 192.168.131.101

  vmserver2 has IP 192.168.131.111 vmnic4 connection to controller 1 IP 192.168.131.102

  Whenever I start a virtual server it causes the dell md3000i start flashes orange, and management tool says disc not on favorite virtual path.

  After entering the tool configuration and affecting the path preferred, from the commencement to vmware, even with a single connected server it causes the error.

  I tried to configure vmware to use direct fixed and alternate paths.

  I did a quick search on Google and found these sites:

  http://www.delltechcenter.com/page/VMware ESX4.0andPowerVault MD3000i

  http://en.community.Dell.com/support-forums/storage/f/1216/t/19269507.aspx

  Strange configuration.

  Looks like you are using some cross cable?

  Each host must have 2 vSwitches, each with a port vmkernel on one of the two iSCSI network.

  Each host must reach all 4 of the MD3000i (test with the vmkping command) interface.

• Range Dell EqualLogic has stopped working when you restart the failure

  During and after an interruption of scheduled maintenance work, ESXi cannot mount on our Dell EqualLogic Array data warehouses and I have no idea why.

  We lack ESXi 5.0.  Shut down us throughout the weekend, replaced the network cables and when we returned to our ESXi hosts could not see the Bay EqualLogic iSCSI, but you could see several other berries on the same storage system iSCSI.  Digging into logs, I see the ESXi host making the CHAP authentication to the EqualLogic Bay, and the said table it connects successfully, then it loses connection about 10 seconds later.  10 seconds more ESXi tent reconnection to the EqualLogic and the same thing is happening again.

  I see several newspapers in ESXi hostd.log indicating this table goes ONLINE and off LINE and another line indicating "sense data Possible" leading me to http://KB.VMware.com/kb/289902 .  I feel really disabled at the moment because it's the Bay of storage accommodation our vCenter Server, which puts us in trouble right now.

  Also, if I try to "Add Storage", ESXi sees EqualLogic stores exist (watch a sufficient volume, size etc.).  However, as I'm trying to add them (via vSphere Client), step 1 takes a lot of time to finish, step 2 indicates the "disks are empty" (which I don't believe), then after an another long this timeout a popup error.

  Are there commands or utilities that are good for the diagnosis of iSCSI specifically?

  I can post more specific journal details if it is useful.

  PS - The new network cables are ok in communication with other storage targets, and it has not replaced the EqualLogic cables.

  Fixed; the MTU setting on my storage switch was mowing part of storage traffic.  Here are the troubleshooting steps that I went through, maybe it'll help someone else.  The solution didn't exactly have anything specific to do with ESXi or EqualLogic.  Basic troubleshooting and digging.

  Newspapers/events storage array inspection revealed he saw and accepted the ESXi host connection appempts.  I saw messages to the effect of:

  -Connection of ESXi iqn blah blah blah established; Successful CHAP authentication.

  -10 seconds later: Connection reset / abandoned by peers.

  -5 seconds later: ESXi connection successfully established...

  (rinse and repeat several times)

  Inspection of the file hostd.log ESXi showed several messages of 'connection reset by peer '.  The storage array and ESXi have been pointing to the other... so the switch is the only thing in the middle.

  Troubleshooting steps now:

  -using the vmkping ping on the table of the ESXi - success: vmkping 192.168.1.20

  -using the vmkping ping on the table of the ESXi with a size of 9000 (jumbo frame size): NO RESPONSE! : (vmkping) s 9000 192.168.100.20<-- this="" is="" where="" the="" money="" was="" for="" finding="" the="">

  MTU has been set at around 9000.  It turns out that the switch should be set a little higher (taking into account headers of packets? who knew)

  So this Setup ran for more than a year of intact working and just stopped when we took everything downstairs and brought it up.

• Reference Dell Equallogic Interface errors

  Hi guys, I got a big problem here in my room. My equallogic iscsi interfaces have a lot of erros. What can be?

  

  First of all, make sure you run the latest version of FW and SANHQ table.

  Packet errors are often the cause of bad cable, bad switch ports and a misconfiguration on switch iSCSI ports.   The only way to erase the mistakes of packages on Equallogic arrays must restart the table.

  • Replacement cable between the controller port and switch port with known good cable.

  • 10 GB cables must be SFF-8472 compliant to work with 10 GB Equallogic arrays.

  • Confirm that the switch is a minimum firmware to work with Berry Equallogic en.community.dell.com/.../2661.equallogic-compatibility-matrix

  (Note: if unable to switch, you can disable protocols spanning tree on ports connect to the table).

  • Use the tech TR1017 report to verify the configuration of the switch and confirm it meets best practices.

  • Run a show of support on the switches to review port errors.   If a Powerconnect or Force10 switch then engage networks dell help examine the switch logs. If another provider, and then engage the seller to switch to help examine the switch logs.

  • Cards network host to firmware update and the latest network card driver

  • The direct link to TR1017:

• Reattach the EqualLogic iSCSI for 2012 Windows volumes

  Hello

  We use EqualLogic, Windows 2008R2, HIT and initiator iSCSI access volumes. Now I'm re - install OS to Windows 2012. All materials, IP addresses, volumes, host name will be the same on the new operating system. BONES of some changes. Will it be the right way to remap the iSCSI volumes to the new operating system:

  1. on windows 2008 R2 take the volume offline in the disk management console.
  2. disconnect "Discovered targets" in the Windows iSCSI initiator.
  3 collect volumes offline in Manager Dell EqualLogic Group (to restore the connections).
  4. the new 2012 Windows Installer 4.5 HIT and set (is this version of the correct software for Windows 2012?)
  5 activate the volumes in the Dell EqualLogic Group Manager.
  6. Discovery target and connect to targets.
  7 collect volumes online in the OS disk management console.

  These steps are correct?
  Are they all necessary?
  Is a correct software 4.5 for windows 2012 HIT?

  Thank you

  Re: connections.  Are you referring to the iSCSI to table sessions?   If so, those are dynamic.  When you stop they will disappear.

  If everything is the same, so technically Yes.  Shutdown, you can reload and bring it to the top.

• ESXi 4.1 upgrade 5.1 in a Dell EqualLogic environment?

  Hi all, I am planning to upgrade our guests ESXi4.1 U1 to ESXi 5.1 Dell R610.  We use a PS6100E EqualLogic via iSCSI.  I installed 5.1 vCenter and prepared Update Manager with the image of Dell Custom ESXi 5.1, thinking that it would contain all the necessary drivers/modules.  However, after analysis of my ESXi hosts, I get the following caveat (see attachment).  Anyone has done an upgrade from 4.1 to 5.1 in a Dell EqualLogic environment?  I'm not warm and fuzzy about the procedure taking into account the warning.  Thank you!

  

  Hello

  There is no requirement for reconfiguration of re - install MEM after the upgrade.  It lies on the existing configuration as before.

  My personal preference is to uninstall 3rd party before the upgrade applications to make the cleaner process.  I don't know problem to upgrade to 1.1.2 and then the ESX upgrade, I have not tried it personally.

• Reference Dell EqualLogic Multipath (e/s high flow)

  We recently bought a Dell EqualLogic SAN. Our main goal for this device was to begin to use pools of resources and be able to do a few HA and Live migration. We have worked with XenServer and Xen Cloud for a while and got no e/s on iScsi performance we were hoping for. With the help of Multipath on the main host machine we get on 250 Mbps (which we are satisfied). On the guest computers, we get only 120 Mbps.

  My question to the community of VMWare; If we wanted to use products VMWare is the possibility to get more then 1 Gbps i/o throughput on a guest PC? And if so, if it is a PDF or a post somewhere that could explain how to do this?

  Let me know, thanks!

  The doc of the correct configuration is attached... hope that her little help. In my view, it is also sub TR docs when you save your table PS.

• VMware HA with 2 x ESXi and Dell MD3000i?

  Hi all

  I have a task at hand to set up with VMware HA.

  What I've done so far,

  (1) to this end, I have 2 identical Dell PE 2950 servers and Dell MD 3000i as storage device.

  (2) installed ESXi 4 in servers (ESXi1 and ESXi2) and configured the static IP.

  (3) I configured the iSCSI SAN (MD3000i) and created the host (VMHA) group.  Added the two hosts in the host group

  (4) virtual disk created, which will be shared by both hosts and it mapped to the host group.

  I know how to install vCenter and how to create the HA cluster as well as adding guests inside.  But before that, I have a few questions.

  According to the theory the shared storage must be accessible by the two hosts.  How can I add storage shared on SAN in the hosts.  I know that the navigation, but miss me the theory somewhere.  I added shared as Datastore2 and ESXi1 and formatted with VMFS3 storage.  Now how could I add the same storage shared in ESXi2?  When I tried to add, the steps asked me to format again shared storage that I can't do?

  Thank you all for all the remedies fast

  Nadine

  You analyze it again on the second (and subsequent).   Add the that storage is being used on the first host.
