Why the store of data/LUN locked automatically

• issue of configuration for the store of data/LUN iSCSI

  Hi all!  I am all new to VMWare and iSCSI, and I have a question about data warehouses regarding being mounted on an iSCSI target.

  Here's my setup.  I have a Dell PowerEdge R810 connected over a link to 10 GB dedicated to a Dell PowerEdge 2950 that I use as a SAN.  The R810 has no hard drives in it, it starts ESXi on a redundant configuration of SD card integrated into the server.  My SAN software is Server 2008 Enterprise with Microsoft iSCSI software Target 3.3 installed.  I created target 1, LUN 0, 800 GB .vhd file sitting on a NTFS partition and set up a store of data on it in VCenter.  The data store is the size of the entire iSCSI, 800 GB target.  I have my first virtual server up and get 50GB of space between the data store.

  Here is my question: can I create several virtual machines using the data store I put in place?  I know it sounds like a stupid question, but my concern comes from some reading I did on several computers, access to a single LUN.  If I set up another virtual machine, it will explode on my SAN file system as two virtual machines would be to access the same big VHD file on the NTFS partion, or I'm far from base?

  Issue of bonus points:

  I have an another R810 that I will be online soon.  Assuming that I am OK to add more virtual machines of my first machine, pourrais I connect this box in the data store as well and create virtual machines, or should I set up a separate data on another iSCSI target store?

  Thanks for your patience with a new guy.  I searched and read for hours, and I could have read too much so I thought that I had just askt experts.

  Hello and welcome to the forums.

  Can I create several virtual machines using the data store that I put in place?

  Yes.

  If I set up another virtual machine, it will explode on my SAN file system as two virtual machines would be to access the same big VHD file on the NTFS partion, or I'm far from base?

  No, you should be fine.  One thing to keep in mind is that the Windows/MS iSCSI target is not a supported storage solution.  There could be problems of scalability with iSCSI Windows/MS, but you'll be fine in a VMware perspective.

  I have an another R810 that I will be online soon.  Assuming that I am OK to add more virtual machines of my first machine, pourrais I connect this box in the data store as well and create virtual machines, or should I set up a separate data on another iSCSI target store?

  You could, but I personally would put in place a different data store on another iSCSI target.

  Good luck!

• Find the store of data with more free space.

  So I'm trying to build a script to configure the virtual machine.

  I'll have it retrieve the node to keep newly available vm out based on the cluster, I said to use. I'm just using the Random function to do that then I select a node in the cluster.

  Where I have questions, how can I

  find the data store less used, based on a particular data store naming scheme.

  I want to say is:

  Hypathetically, I for example named data warehouses:

  store data-prod-01 200 GB free

  store data-prod-02 500 GB free

  free data-prod-03 10 GB store

  free data-qa-01 200 GB store

  free data-qa-02 1000 GB store

  I want to throw in a piece of code to tell him to watch data warehouses "datastore-prod *" and place the virtual machine on the store of data with the most space. (that's assuming that the vm will agree on the DS and let fresh generals)

  I guess I want to know if it is possible?

  I would also be concerned about scenario that perhaps the vm should I build just will not match on any of my other data store. I guess I need a logic to check if it is still possible.

  This is more than a wish rather than a necessity. I'm thinking if I just read the info, or use a cvs file after running the script. Any recommendations would be greatly appreacted.

  Hello, drivera01-

  You should be able to do this with a very small amount of code.  Download all data warehouses that correspond to the model name, sort free space (in descending order) and select the top one.  As:

  ## get the datastore matching datastore-prod* that has the most freespace$oDatastoreWithMostFree = Get-Datastore datastore-prod* | Sort-Object -Property FreespaceGB -Descending:$true | Select-Object -First 1
  
  ## if the freespace plus a bit of buffer space is greater than the size needed for the new VMif (($oDatastoreWithMostFree.FreespaceGB + 20) -gt $intNewVMDiskSize) {<# do the provisioning to this datastore #>}else {"oh, no -- not enough freespace on datastore '$($oDatastoreWithMostFree.Name)' to provision new VM"}
  

  The second part, where it checks for sufficient freespace on the data store that has the most free, can be updated to behave as you need, but that should be the basis.  How does this look?

• PowerCLI - there cmdlets to browse the store of data for files/directories and their creation?

  Hello

  PowerCLI - there cmdlets to browse the store of data for files/directories and their creation?

  If Yes, can you please let me know.

  I took a glance at the reference of the cmdlet, but can not find...

  
  Kind regards

  Dreamer

  You can use the data store provider.

  It is documented in the vSphere PowerCLI Administration Guide that was installed with PowerCLI.

• Space in the store of data not released when a virtual machine is removed

  Hey all,.

  I have a game fairly simple up - two servers ESXi 2 Terminal servers. I'll have a problem, but with space in the store of data not be released on one of them after that I got a clone to the virtual machine, made my changes and removed the original. I can find no record anywhere, using vSphere (not in the inventory or when I browse the data store), but the HARD drive space using the server is still assigned somewhere.

  Any body have tips on where to find or how to fix this if it is indeed a problem?

  Any help is greatly appreciated.

  Thank you.

• Increase the store of data in gray

  Hello

  I have vmware vcenter server hosts 7 Pentecost and clarion cx4 storage connected.

  I want to increase one of the datestores.

  the size of the data store is 200 GB end I want to increase the size of 300 GB

  I have expanded the original LUN on the CLARiiON and then refresh the display of data warehouses, but the increase option on the properties of the data store is always grey.

  On the properties of the data store, I can see the extended device and hes chenged to 300 capacity.

  whay I can't increase the size of the data store?

  the type of data store is vmfs3.

  appreciate the help

  So now, a single 300 GB LUN is presented to your ESX, while the first 200 GB was already registered by ESX and the 100 remaining is not allowed for the increase.

  If the same 200 GB lun has been expanded, so you can try to remove the LUN and add it again after a new analysis. Disassemble is available since version 5.0.

  If the 200 GB of critical data is not, then you can remove the lun on the storage side and to assign the lun to the ESX and of course rescan after tat

• 2.0 server loses the connection to the store of data on reboot

  I will install ESXi on my server in the very near future. I just ordered another NAS (Buffalo Terastation Pro 2 TB II) and prefer to use it for a data store since I can't afford a SAN skinning in LUN for my virtual machines.

  I'm running 2.0 on a Windows Server 2003 Server. I have a problem and I was wondering if you had this happen or know how to prevent it from happening.

  I copied some of my virtual machines from the current server to a 1 TB NAS (Netgear Ready NAS NV +) which is located on the network. I added the data store to the server pointing to it as a CIFS share. Everything seems to work fine until I restart the server... then it can not find the data store. I tried refreshing the data store, but it does not. I have to actually remove the data store and Add again... If I just try adding another store of data that it knows that it is mapped to the same location and she won't let me. So I remove, add a data store and computers virtual it appear in the server...  I thought I could try the drive mapping to the location of the data store but it won't let me just use the drive letter mapping, it requires the name of the folder too... Any thoughts?

  Thanx

  There is a workaround solution posted here:

  http://communities.VMware.com/message/1098864

  BTW. I found it by searching the community for "CIFS".

• We can dynamicaly fill the store parameter data in OEDQ?

  Is there a way where we can dynamically fill in the parameters of data store that varies from env to env to OEDQ, in reading common file of param.

  This will avoid the hassle of conflict and maintenance for all future password or port changes.

  
  

  
  

  Kind regards

  Yes, you can do so by Instant exteriorization and exports, because these are executable tasks that use the data store settings. You can then replace the settings stored with the real settings needed to run using command line parameters or run profiles.

• At what level is the store of data latency measured?

  Hello

  I have a question about latency of data store. I see that, generally, 20 to 30 ms latency limit before having the performance issue, but at what level is this limit? It is the seat of the latency of the VM? See vsphere?...

  In Vcops, when I select a data store and access operation - details see read/write latency: see comments AVG or device AVG? (see image below)

  

  When I select a VM in Vcops to see the latency time "of virtual machine", what is the difference between latency vDisk and the VM latency data store?

  

  I know there are a lot of questions in one thread, thank you in advance to those who take the time to answer.

  As esxtop counters, you have different counters to measure different parts of the stack. If you have latency at a disk level your queues will be filled and reflected. Latency of disk order is good enough to pick up underlying storage latency, but it depends what resource you are watching. The attributes derived from 'latency' exist here and there which are calculated based on the type of storage/etc to simplify your life and give you one place to search.

  When you start to look at the latency of the queue, you must keep in mind that focuses only on the queue. Take a look at the Duncan article (ESXTOP - bricks yellow) on it and your questions will probably be kept clear with regard to what are the bits/s and for the disk counters.

• Expansion of the store of data RAID 5

  Hi, I have a store of data on disks RAID 5 4 and I want to add more than 2 drives in RAID 5, is it possible to add the data store / RAID 5 arrary keeping the data store existing / (VMs) data intact?

  Thanks in advance!

  You must enter your PERC BIOS.

  Follow the manual of Dell.

  And (like writing above), perform a full backup before you start.

• Error creating the store of data on iSCSI LUN (EMC CX4/120)

  I run an error when you try to create a data store on a Clariion CX4/120 system.  Connectivity to the San is performed via iSCSI.  I exhibited with success the target on the storage card and it shows in Configuration > storage adapters > vmhba33 > Details.  It has a capacity of 5.37 to.

  When I go to Configuration > storage and select Add..., I can select the disk/LUN.  The LUN appears here as well.  When I click Next, it fills the device information and location and also reported "the HDD is empty."  After 10 minutes, it generates the following error...

  Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" of object "ha-datastoresystem" on ESXi '172.20.100.78' failed.

  I did some research on Google and looked around here on the website of VMware, and I can't find any references to this error.  Are there log files for the process that I can look into?  I must engage EMC and see if there is a problem with the SAN itself?

  It has a capacity of 5.37 to.

  VMFS data storage limit is 2 TB less than 512 bytes. Try presenting small LUN, then it should work.

• Deleting files from the store of data using vSphere SDK

  Hello

  I'm doing a backup script that is supposed to clone a machine once every day.

  The steps that I'm trying to achieve is to first delete the old copy of my clone (this because vCenter won't replace the files). So I want to clone again and he unsubscribe vcenter because we do not want it displayed in our inventory.

  I got in regards to cloning and unsubscribing, but deleting files seems to be a bit more complicated.

  I tried a few approaches, I tried to vmdkManagement.pl that is not quite what I wanted (also tried change it without the desired result).

  I tried to figure out how to write my own script to delete, but the API is out of my reach as to understand how the neccessery objects correctly.

  Can someone help me with an excerpt from script (between Util::connect and Util::disconnect) or another approach to this issue?

  I must mention the data store is a NFS share and VMware seems to lock the files that prevents me to run a scheduled task to delete or using methods of perl (rmtree or untie) to delete files.

  Best regards

  1. you must use 'in the filename parameter.

  2 If you use vcenter you datacenter parameter specified in the function DeleteDatastoreFile

  #!/usr/bin/perl -w
  use strict;
  use warnings;
  use VMware::VILib;
  use VMware::VIRuntime;
  
  my %opts = (
     filename => {
        type => "=s",
        help => "filename to delete",
        required => 0
     }
  );
  
  Opts::add_options(%opts);
  Opts::parse();
  Opts::validate();
  Util::connect();
  
  my $filename = Opts::get_option('filename');
  
  my $fm = Vim::get_view(mo_ref => Vim::get_service_content()->fileManager);
  my $datacenter = Vim::find_entity_view(view_type => 'Datacenter');
  
  eval {
     $fm->DeleteDatastoreFile(name => $filename, datacenter => $datacenter);
  };
  if($@) {
     print("An error occured\n".($@->fault_string));
  }

• Why the iso 9.3 has locked my iPad Pro?

  Last updated on Saturday, seemed OK at first, but soon things stopped working.  Very frustrated to work only a few apps and Face Book - I can't use the internet as no link a search doesn't work, not in Safari or Chrome, disabling Java makes no difference whatsoever.  Also, as soon as I tap on any link in an email, the program locks and E-mail can do is to close.  I can't access what anyone online to all.  There are warnings that there could be problems with authentication on the older device, but it is a new iPad Pro.  This means that I can't do all the work on this at all.

  Rang the Apple Support and spoke to a very polite Lady, but everything that she tell me was that the engineers are working on it! She also said do not attempt a roll back - all done that?  Is it safe?

  Even if this isn't an apple site, it seems not accorately track which versions are allowed.

  see which versions are allowed:

  http://API.ineal.me/TSS/status

  I think you will be ok with decommissioning, just to ensure that you are using a version authorized by apple as shown above. At times, Apple suggested that downgrade you when a clearance blocked phone calls on some iphones.  Sometimes in the past, employees of the apple stores would help you downgrade.  Ask.

  For a limited time Apple will return you to the previous version.  Do not hurry.
