  Dear all,

  We have enclosed a case at VMware, please find their findings on the same.

  ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

  After the webex session, we just had, I discovered the root cause of the problem reported to an underlying problem on the block device (the logical drive, or a problem on the Board) presented to accommodate the data in question store successfully.

  In short, whenever we try to do raw reading from the disk (from sector 0), the same always fail when we reach the 30932992 bytes (31 MB) brand with an IO error (which is consistent, he is always on this region of the disc that read operations fail, no more, no less). This result can be seen, even if no partition is in the disk (using if = / dev/sdb instead of/dev/sdb1 with dd) and even after zeroing on all sectors (if dd \u003d/dev/zero of = / dev/sdb). Strangely, read operations work fine (as he writes zeros of random data) throughout the entire disk. Keep in mind that the tests I did with no VMware tools (I used almost only dd for these operations), which prohibits certainly a VMware problem (in fact, if you were to try to start the server with a Linux live CD and run the same tests that I did, you would see the same behavior).

  I know that there is no report of material of any bad behavior on the table, but data collected with our tests today completely invalid who. The next step is for you to take this to the server provider to check for problems on the table or discs, because they are there and they are the reason for the problem you reported initially.

  Please let me know if you have other questions about it.

  Thank you

• Can photos be deleted from the data store directly?

  Hello

  I just doubt. Can shapshots be deleted directly from the data store.

  I checked the Snapshot Manager, but was not able to locate snapshots in it, but at the same time there were three snapshots in particular virtual machine data store. What it means?

  And what is my isNativeSnapshot = 'no'?

  I just doubt. Can shapshots be deleted directly from the data store.

  No, snapshots work as a string. Deletion of one of the links in the chain breaks the chain. Please take a look at http://kb.vmware.com/kb/1015180 to see how snapshots work.

  I checked the Snapshot Manager, but was not able to locate snapshots in it, but at the same time there were three snapshots in particular virtual machine data store. What it means?

  Information about snapshots are kept in .vmsd the virtual machine folder. If this file is corrupt - for some reason-you won't see the correct string snapshot in the Snapshot Manager.

  Please create a list of all files in the folder of the virtual machine (dir *. * /oen > filelist.txt (for Windows) or ls-lisa > filelist.txt (for Linux)) and after (tie) the filelist.txt, file .vmx VM as well as the file .vmsd for your next post.

  You cannot view data from a store of essbase data as it is not configured with a driver that supports this feature

• Help display information from the data store

  Hi, I'm trying to format a table with information from various commands, and I can't find out how to do it.

  Basically I want the table to have the following information:

  ESX host - DatastoreName - CanonicalName - CapacityMB - MultipathPolicy

  The problem is the get-scsilun cli annoys me only the canonical ability and multiple trips, but I want to add the other get-vmhost and get-datastore information

  The command I'm ussing is:

  Get-vmhost | Get-ScsiLun | WHERE-object {$_.} Seller - eq "EmC" - and $_. LunType - eq 'disc'} | Format-Table-property CanonicalName, CapacityMB, MultipathPolicy-auto | Out-String-width 120

  No idea how to do that?

  Thanks in advance!

  Pablo. -.

  Try something like this

  $report =@()
  
  foreach($esx in get-vmhost){
      foreach($lun in (Get-ScsiLun -VmHost $esx -LunType disk | where-object {$_.Vendor -eq "EMC"})){
          foreach($ds in (Get-Datastore -VMHost $esx)){
              $ds.ExtensionData.Info.Vmfs.Extent | %{
                  if($_.diskName -eq $lun.CanonicalName){
                      $row = "" | Select Host,DS,CanonicalName,CapacityMB,MultiPathPolicy
                      $row.Host = $esx.Name
                      $row.DS = $ds.Name
                      $row.CanonicalName = $lun.CanonicalName
                      $row.CapacityMB = $lun.CapacityMB
                      $row.MultiPathPolicy = $lun.MultipathPolicy
                      $report += $row                }
              }
          }
      }
  }
  
  $report | ft -AutoSize
  

  The link between the data store and the logic unit number is done by comparing canonicalname the LUN with each canonicalname of the extent of the disk of the data warehouses.

• Please help: measure is missing from the data store

  Hello

  I have an a 20 TB drive data store and a magnitude of about 40 TB (local disks, areca raid controller).

  Long story short, I had to delete and re-create the volume 40 to on the RAID controller (without initialization, of course).

  Now all the data is there but eui has changed for the 40 to volume and vmware is unable to mount.

  log/hostd.log:2016-05-10T07:17:16.107Z of information pass [3D380B70] [Originator@6876 sub = Vimsvc.ha - eventmgr] event 118: a connected device eui.001b4d2051676528:1 may be offline. [Backvol1, 55e980d4-386dfa7f-7cb2-0cc47a09ba36] file system now is in a degraded state. While the data store is always available, parts of data residing on the extent which went offline may be inaccessible.

  Can someone help me please?

  Thank you!

  Hello
  You asked for instructions on how to readd a missing measure.
  Basically, it's pretty easy:
  in the VMFS to VMFS-based volume header section, you can assign extends it.
  Lets say that the basic volume is mpx.vmhba1:C0:T3:L0:1
  first of all extend is mpx.vmhba1:C0:T4:L0:1
  second extension is mpx.vmhba1:C0:T5:L0:1
  Then you will see this string in the VMFS header:
  vmhba1:3:0
  and a little later

  MPX.vmhba1:C0:T3:l0:1

  MPX.vmhba1:C0:T4:l0:1

  MPX.vmhba1:C0:T5:l0:1
  Just change the list of stretches.
  But: normally you can't change this section at all, and to add to the confusion, these values are stored in RAM is not trivial to change this value correctly.
  I highly recommend that instead of try it yourself and repeat all the mistakes I made while learning it - call me.
  I rather help you personally to give dangerous advice that will probably make things worse.

• Find a VM (from the data store, file, the pool and etc..) ID name

  Hello:

  I wonder if there is a way to find the virtual computer (of esx, the data store, file, the pool and etc..) ID name of vSphere CLI power.

  The goal is to find the virtual if name machine ID if known (and the same for esx datastore, record pool and etc..).

  Thank you

  Olegarr

  Hello

  According to my understanding, we can get the managed object ID of the virtual machines,

  $serv = connect-VIServer-Server

  Write-Output $vm. ID

  The same with others, like first Get-VMHost, store in a variable and then the variable. ID gives you the code.

  I hope this helps.

• Loading of the keys from the data store

  Hello
  
  I have a near cache, supported by a cache partitioned using a dumps. When I call cache.keySet (), I get only the keys that are currently in the partitioned cache. Not those who have been expelled for dumps. Right?
  
  If I would also like to receive those, can I retrieve it from the database separately? Or is there another way?
  
  Best regards

  Fix. The cache does not remember anything on the expelled entries, they are as if they have never been.

  user10601659 wrote:

  If you know these keys, you can simply ask that them and load the cache-store them. If you do not know the key, then you must go to the database to find out them and either put the data in the cache of your own (and do it in a way that the cache-store won't write their), or you must apply entries with the now well-known keys.

  Jan

  You can write a cache store hides another which takes query parameters including a key cache, and on obtaining a value, it returns the result of the query according to the query parameters as a value cached. You should be aware, however, that this cache will contain deep stale data, then you probably want to configure this cache of very rapid expulsion.

• Install centos6.4 of the data store

  Hello

  Does anyone know how can I install centos 6.4 on vm. I have the file iso centos on centos6.4_2.iso and vmware server /vmfs/volumes/isos/centos6.4_1.iso

  I selected vm - material - cd/dvd-> iso datastore stressed the centos6.4 - 1.ISO, then connect to option is under

  When I start the VM in a single step, he asks where is the binary located [cd/dvd, nfs, hard drive mounting and url] how can I tell the virtual machine it needs to install from the data store [which is on vmware server 5.x]

  Hello

  during the installation process will be o.s. installed from cd/DVD, as in the physical environment and it is not necessary specify a data store location. I think you may have an invalid ISO. Check its integrity...

• Not enough space on the data store. Could not power on VM:No space available on the device

  Hello

  Here's my problem. I have several virtual machines. But one of them can be powered on because of the problem of space. I can not add spaces because there is nothing to add. The data store is only 760 MB left. There is summary information about the virtual machine below. I need power somehow on this machine, but how can I do. can I add another data store space. Y at - it files I can delete from the data store. Snapshot file is considerably large, I can reduce its size without changing anything.

  Thank you.

  

  There are several ways to approach this problem

  1. you can storage vmotion, some VMs who are currently used and this will free space.

  2. check the clichés that you don't use, and delete those.

  3. reduce the memory of some other virtual machines which are turned on so that the swap space can be saved.

• ESX host cannot see the data store

  Hello team, I have vcenter management 5 2 host esxi5. now added an esxi4 in the cluster and added iniitators for file systems. I can see the paths under this host of esx4 showing the LUN of the registrants. but I'm not able to see the data to store. When I tried to edit a newly created virtual machine to find the iso from the data store, it shows only the local hard disk of the host, which is a UCS blade. exsi5 hosts the two ok to see all data stores. can someone tell which part is wrong? Thank you!

  Looks like there is no problem with the presentation of the logic unit number since you can see the path to the LUN from the host.

  Is - these created data VMFS storages are 50 ESXi? If so, the VMFS version 5 (VMFS 5) which is not supported in ESXi 4.1.

  In this case, its expected that the host ESXi 4.1 will not show VMFS5 data warehouses.

• Method to move the virtual machines in the data store temporary so I can rebuild pool recommended NFS

  Our current data store is a mounting NFS on Nexenta (zfs), which has a pool, I need to rebuild (migration of raidz2 to mirror striped for performance). Initially, I was relying on the judgment of all virtual machines, create a new pool, copy (cp - r) of the Nexenta console all virtual machines to the new pool, recreating the pool mirror and then copy (cp - r) all the data back.

  I have seen several discussions on this topic and seems like the simplest method would be to use the feature to "Migrate" so that the virtual machines are not fragmented. However in some of my pre-test when I copy a virtual machine between the basins of the Nexenta console it appears (from the data store Explorer) to initially create the vmdk provisioned and then once completed it copy looks too thin.

  I hope that I can simply copy the Nexenta console, using the option "Migrate" in vCenter on each of my 40 MV looks like it would be * quite * tedious compared to the simple issuance of an order of 'cp - r' and leave all the copies of VMs (1.5 to) during the night and then adding them to each host.

  Does anyone have experience with this? Or maybe a way to generate scripts easily (?) the option "migrate" in vCenter?

  Thank you all!

  You can select multiple VMs in vCenter regularly using CTRL + click or shift + click and both migrate them as long as they have the same storage destination.  You can also schedule it as a task.    Add manually each computer virtual back in hand is not less painful than migrating individually, anyway.

• EagerZeroedThink! Why read i/o on the data store while inflation

  Hi all

  I got a call from a customer of 2 weeks ago asking why there reading activities on its data store when it swells a vmdk. I didn't either, and did in my Infrastructure to justify.

  Whenever I created a vmdk for EagerZeroedThick, with the Virtual Machine Wizzard (functions of Clustering Support etc.) create or inflate the context. Prezeroeing starts at 1/3 of the activity is read from the data store and the other 2/3 is in writing. I expect 100% writing to the data store since I thought that prezero a full vmdk involves only write operations (write zeros). The data store does not support vAAI and tried since with EMC and Netapp subsystems, Fibre Channel and iSCSI. Its always the same. With EMC its even more read than write operations.

  Anyone have an explanation for the behavior of ths. I looked around and didn't find anything.

  Thank you

  Harry Mitschele

  VCI and senior Consultant

  The way I understand it, the process of resetting (no matter if it has run for a newly created or an existing vmdk) zeros only blocks that are not already reset to zero. That's why he should read each block before eventually writing on it.

  Take a look at KB http://kb.vmware.com/kb/1011170 (section "vmkfstools-t0") which deals with the topic of zero setting.

• Cannot download the files of the virtual machine for the data store

  Hello

  I get an error message "connection to the server timed out" while I'm trying to download the files from the virtual computer from the data store.

  Although the ESX and my laptop are on the same network, I get this error message.

  Please let me know if I need to take care of something.

  I think that hard & .vsmp be used & locked is why you are unable to download it. Try to download the file, whereas the VMs system is turned off
