• Create a new VMFS datastore

  Hi guys,.

  You have a few examples or a simple way on the creation of a new VMFS datastore using Orchestrator?

  Thank you.

  Hello

  check the "Create vmfs for all available disks" workflow in Library / vCenter / storage.

  It contains a logical example creating VMFS data warehouses, you should be able to adopt it for specific volumes.

  Also, check out ONYX and Onyx for WebClient Onyx for the Web Client to find the needed API calls when you create manually in the client.

  Kind regards

• Cannot add VMFS datastore to ESXi host

  Hi all

  I have a problem with the CF 1 logical unit number which can be seen as a device through several paths on all 10 hosts in a cluster, but it appear as a data store VMFS on 6 of the hosts. Other LUNS of the same Bay appear correctly on all hosts. 10 guests see the LUN with the same LUN ID and all hosts are identical regarding the version of ESXi (5.0 Update 2), HBA and firmware models.

  On the 4 hosts who can see the device but not the VMFS data store, it seems that he sees the LUN as a snapshot: 'list of snapshot storage vmfs esxcli' translates into:

  4f5e5cbb-a87cd2c6-86e9-d8d385f98034
  Volume name: LUN101_SAS2
  VMFS UUID: 4f5e5cbb-a87cd2c6-86e9-d8d385f98034
  Can mount: true
  Reason of mountability-United Nations:
  Can will: false
  Reason for non-resignaturability: the volume is actively used
  County of measure pending: 1

  The UUID VMFS above matches the UUID VMFS seen on 6 guests who can see the VMFS data store.

  When I try to use 'Add storage', the device appears with a lambel VMFS: LUN101_SAS2(head). I don't know why (head) was added to the label of VMFS. Oscreen n the following signature to keep 'existing' and "Assign a new signature" options are grayed out. The only option is "Disc Format. I need to keep the existing signature because it run virtual machines that have their files .vmx and hard on this LUN.

  Would the fact that I have virtual machines running on this LUN, I cannot choose the option to "keep the existing signature?

  I need to Storage vMotion these virtual machines to a different LUN before I add the VMFS datastore to 4 guests?

  TIA

  Hey RoscoT;

  Try the following command

  #esxcfg - volume - l

  This should show the volume

  To constantly increase the volume, use esxcfg-volume - M followed of the UUID or volume name

• Maximum VMs per VMFS datastore

  Can someone explain to me why the general rule concerning the number of clones linked by VMFS datastore is supposed to be 90, safer at 60? (39:00 in the video)

  My VMFS data store can handle more IO wise and wise, so why would I limit this number of storage? Numbers wise, I can run 120 VM out of a 2 400 GB data store.

  Here are estimates based on the data accumulated on the ground.  If you can get a larger number, it's fine.  These figures will be based on the IOPS / s, its use for the end user, locking, back-end storage, etc.  Basically the storage i/o profile of the entire group of the Active Desktop disk activity goes beyond what the back-end data store is able to provide.  If there is no offset in a desktop experience virtual because the affirmation of storage, revealed by tests or the use of your actual deployment, the number of clones linked by the data store can be merit to be studied.  For starters, these figures are given for the initial orientation.

• Cannot extend VMFS datastore

  Mary!

  I have a virtual machine with two partitions. Partition for the system (IDE) and (SCSI) partition for data. The partition of SCSI has there own underlying the LUN on a storage. LUN capacity was 50 GB where the VMFS data store uses almost the full ability of LUN (49, 75GB). So I developed the LUN on the storage of 60 GB and now I want to extend the data on this LUN VMFS store and add a few more GB. But although I can see the raw capacity (60 GB) of the LUN in storage/properties for this VMFS datastore I can't expad the datastore to VMFS himself. When I click on expand I get no device/LUN to use.

  Any suggestions?

  And my main goal is to expand the data store VMFS.

  It's exactly what I got. When you log on to an ESXi host (using the vSphere Client and the root user), you will have the same storage Wizard dialog box as in the screen shot you posted before. After logging in, go to 'Configuration'-> 'Storage', select the datatstore VMFS, you want to develop and run the wizard.

• Failed to create full-size VMFS Datastore on large virtual disk on Dell R710 5 2 t + 1, Raid 5 PERC6i controller

  ESXi4, I installed it on my Dell R710. She has 6 1 TB on PERC6i SAS drives, 5 discs do Raid 5 with hot spare disk 1. And I created 3 VD, 1 is from 40 GB to install the OS, 2 is 1 TB to contain the model ISO and VM and 3 is 2.6 TB to contain the VM.

  After installing ESXi4, I found only 2 created Datastore: 2. 39 GB 1 Datastore and 1 TB data store no data store has been created on the VD 2.6 TB.

  I tried to create it manually, but I found that only 635 GB in size can be created on this 2.6 t. Why? As I remembered ESXi4 can support up to 64 TB VMFS Datastore.

  The BIOS is 1.0.4.

  Someone had the idea?

  Take a look at this "vSphere and 2 TB LUN has changed VI3.x.

  http://virtualgeek.typepad.com/virtual_geek/2009/06/vSphere-and-2TB-LUNs-changes-from-vi3x.html

  Oh, a data store to 64 would consist of 32 degrees to ~ 2 TB. The limit on the size of the LUN behind the data store is 512 b less than 2 TB

• PowerCLI script for VMFS datastore list with ID NAA and latency?

  Hi all

  Can anyone here please share a script, or help me to change the PowerCLI to display the store name of VMFS data, capacity and NAA.ID and latency in the past 24 hours?

  So far I can only use the WHowe script below:

  $esxName = "PRODESXi10".

  SE PRODVCENTER01-connect-VIServer-Server "VM".

  New-VIProperty-name lunDatastoreName - ObjectType ScsiLun-Value {}

  Param ($LUN)

  $ds = $lun. VMHost.ExtensionData.Datastore | % {Get-view $_} | `

• VMFS Datastore 3.33 more than 2 TB?

  I was wondering if I could spend my store of data from more than 2 TB which is a VMFS, block of 4mg 3.33.

  Thank you

  The maximum size of data store can be up to 64, but you'll need multiple 2 TB LUNS and add them as extensions. Keep in mind that with 4 MB block, the maximum file size is 1 TB. Another option is if you are running vSphere ESXi 5.x, you can install the VMFS version 5 and take advantage of larger size of the LUN with VMDK support, anyway if you are in this case, I recommend you create a new data store and migrate the old data store data.

• many partitions on a VMFS Datastore!

  Hi all

  Can you please let me know why I have multiple partitions on a partitions VMFS.

  It's a given LUN again and we formatted VMFS 5.

  Any suggestions why so many partitions?

  

  Thank you

  On the screen, it seems that it is a startup logic unit number.

  Please see below KB for details of the partition.

• Cannot resize VMFS DataStore in ESXi 5.1

  All,

  I use a network SAN OpenFiler as a VMWare Datastore.  The current size of the data store was 1 TB and I decided to increase the size of the LUN via OpenFiler to 2 TB.  However, this increase in the logic unit number size is not reflected in the VMWare Datastore and I cannot increase (extend) the size of the existing data store.  I seem to be affected by the same problem as described here:

  VMWARE: Cannot expand / increase Datastore VMFS on ESX

  Any ideas on how to increase the size of the data store in ESXi?

  Thank you.

  Then, it might be a problem of presentation. try not represented this LUN from the storage host and re group - present.

  Ensure that the data store is dismounted and detached from everything first.

  Thank you

• VMFS datastore and advised LUN (IO queue)?

  Hello

  I have a few quick questions regarding best practices SAN LUNS and VMFS data warehouses.

  Assumptions:

  1 iSCSI SAN (single storage processor)

  2. 2 disk pools (2 x RAID5 @ 3 discs/RAID5)

  3 4 LUNS (LUN/Disk 2 pool)

  4 LUN size: 500 GB/LUN for a toal of 2 TB of storage

  Question:

  1. on what data store VMs would have a larger disk performance?

  A. Datastore1 created on LUN0 on disk pool 1 and Datastore2 on LUN1 on disk pool OR 1

  B. Datastore1 created the LUN0 on disk pool 1 and Datastore2 created the LUN0 on disc 2 of pool?

  I guess what I'm trying to ask here is to have LUNS on clusters of separate drives faster than to have all the LUNS on the same disk pool? If A VM hard exists on Datastore1 of B above, setting hard of VM B on Datastore2 of B above would improve the overall performance for both virtual machines? On the other hand, respectively, capping A VM and hard of B VM on Datastore1 and Datastore2, of A above still an effective option? This brings me to question 2.

  2 - is data on separate warehouses LUN fracture the queue of e/s of SAN LUNS on all LUNS? In other words, the SAN will access all LUNS at the same time, thereby increasing the performance vs having all VMs on a single LUN shared with a single e/s queue?

  Thank you

  Steve

  In General, you're trading the guaranteed 90 IOPS / sec per IOPS VMDK / s maximum 180, but shared between 2 VMDK.

  This seems to be an entirely theoretical question and sometimes almost philosophical, whether for trade this broad for this.

  If you think about it more later, it is quite similar to place vCPUs and VMs on ESX host - is it better to share some CPU more Rapids (= more expensive systems) or gives a processor dedicated Basic (= more material)?

  If I stick my neck, I would say that the difference between the aforementioned buildings is visible only marginally and you could probably be very happy with a flat 6 pin R5 datastore as well.

  But the specific difference between 2 R1s and an A10 with 2 LUNS or even a R10 with 1 LUN but 2 VMDK worth thinking.

  As I've already said:

  If speed and performance is a problem (MSSQL IOPS requirements) then you're already wrong with the SATAs and plan instead to study in an array of more powerful than to try to get the last bits of your SATAs.

  Don't get me wrong, surely SATA can do miracles in the small environment, but especially if I notice a 50 GB DB MSSQL for P2V I would first collect some perfmon data and plan my storage as a result even more than I would normally do in SMB environments.

  You will not get a PRIUS to take the load of a SUV, no matter how long and diligent, you plan to distribute the load.

• ESXi 5.5, 5 VMFS datastore / vmdk size question

  Trying to check that I understand the vmdk for esxi 5.5 size limitation.

  If I have a VMFS 5 existing on my 5.0 esxi hosts, data store once I update my hosts to esxi 5.5 that I would then be able to have vm with vmdk is greater than 2 TB?

  I don't have to create new warehouses of data VMFS 5 after the upgrade to esxi5.5 take advanrage of the change in file size limit?

  Thanks for any help.

  That's right, at least in part. In addition to the upgrade of the host, you must also upgrade the hardware version of the virtual machine (Compatibility Mode) to take advantage of larger virtual disks (up to ~ to 62). However, always keep in mind the time needed to restore the virtual disk together where this is necessary. With 1 Gbps - assuming that you have the full available bandwidth - 2 TB will require more than 5 hours already! Then maybe organize the data in several virtual disks may be a better solution.

• Could not introduce additional new 1 TB in the VMFS datastore to the ESXi Server?

  Hi all

  Does anyone know what should I do to make my 1 TB of hard drive using my eSATA connector housing on the HP DL 360 G7 Server?

  I installed the card eSATA PCI Express successfully on the server as is apparent from the screenshot of console vSphere below:

  

  but for some unknown reason, I do not see the hard drive 1 TB after multiple Rescan, still in white or nothing to present to ESXi.

  Here's what can see the BIOS of HP Server:

  

  When I move the eSATA connection to my Toshiba laptop, it went well, I can transfer the data and format the drive in the enclosure eSATA.

• VM is unable to see on host vmfs datastore

  
  I have 2 VM v.10 who are unable to see / connect to a vmfs on the host computer data store in the web client. The host is 5.5 and I have 2 other hosts and virtual machines that are 5.5/v.10, which can see the store of data very well and can be seen in vcenter 5.5 fine.  It is a utility data store shared between hosts on which conserve us resources of the ISO that was originally formatted on a host 5.1.

  Figured this out, the new web interface can be difficult sometimes. As the data store was not already be available to the virtual machine, it was not available in the CD menu by default. I had to go in the settings of the virtual machine and click the browse option to access the data store. Once this had been done, it was visible through the menu of the CD.

• P2V to multiple VMFS volumes

  Hello

  We have a physical file (Windows Server 2003) server with eight volumes (C, D, E and so on), all volumes are less than 2 TB each, but overall, they are superior to 2 TB, so if I want to virtualize it I put the VMDK files on different VMFS volumes (since VMFS volumes can be maximum 2 TB).

  Is it possible to put the VMDK files to different volumes VMFS with VMware Converter? If this is not the case, how world you do this?

  Yes, it is possible. When you get to the "Destination Options", choose Edit.  From there you can choose you destination data store (s)

  .. all volumes are less than 2 TB each

  Make sure that you have the data warehouses that are 8MB, otherwise you will not be able to P2V guest.
