Storage vmotion - Vaii integration?

I find myself being unclear about what integration VĂII means and how to activate it, and I'm not sure when / if and under what circumstances one table will perform most of the work of a storage vmotion.

using vshpere 5.1 business + and a new array of netapp - want to migrate data from a former EVA4400 to the new netapp. If we vmotions storage, one or other of the storage devices will do the real work of data movement or guests will have to make it to the top of the layer of software?

And if the berries will participate (which makes the process faster and less cycles consuming cpu on the host computers) is there anything I need to do, to allow the integration of VĂII on one of these paintings?

This FAQ will be a good read on VAAI.

in this scenario, VAAI cannot do much, since the soruce LUN and target are on different storages. For the improvement of VAAI both source and target storage vmotion LUN must be on the same storage which is compatible VAAI.

And if the berries will participate (which makes the process faster and less cycles consuming cpu on the host computers) is there anything I need to do, to allow the integration of VĂII on one of these paintings?

Side table we don't need to do much. Just check with the seller to array storage OS is compatible VAAI and his default license.

On the side of the host, VAAI is enabled by default.

To determine if VAAI is enabled by using the vSphere Client.

  1. In the vSphere Client inventory Panel, click on the host.
  2. Click the Configuration tab, and then click Advanced settings under software.
  3. Make sure these options are set to 1 (enabled):

    DataMover.HardwareAcceleratedMove
    DataMover.HardwareAcceleratedInit
    VMFS3.HardwareAcceleratedLocking

Consult the above KB to enable VAAI if this is not enabled by chance.

  • ESX 4.0 Storage vMotion

    I'm looking for a good doc or webenar on storage vMotion

    Storage VMotion is integrated in VSphere if you are using the Evaluation Version or are licensed for use with the version of VSphere that you use.

    To use Storage VMotion, right-click the virtual machine and choose migrate - if you have a license for Storage VMotion, and multiple LUNS which Storage VMotion can use then you should see the choice for host of change, change or change host and storage storage.

  • Storage vmotion very slow

    Storage vmotions run very slowly. The virtual machine that has a 60 GB HARD drive. I tried different storage and still the same result. I have even upgraded to a network of 10 GB with the same results. I opened an evidence of support and the engineer told me vmotion will not use the link in full speed but it seems quite slow for the numbers I get. I hope I have provided enough information below for assistance. I hope that it is something I am doing wrong...

    Hosts:

    3 x ESXi host. Two are updated to version 6.0 1 and a version 5.5.

    Dell PowerEdge R610

    Xeon E5540 - 8 x 2.53GHz

    48 GB OF RAM

    10 GB for storage and vmotion traffic

    4 x 1 Gb NIC for vm traffic interconnection

    All storage is on the shared storage. The only local thing is the operating system

    VMware EVC mode for the production of Intel's Nehalem.

    Storage

    Supermicro NAS 2 to 4 x 4 RAID 10 storage pools

    Integrated 10 GB NIC

    QNAP TS - 469U - PR to 4 x 4 RAID 5 NAS

    2 x 1 GB NIC aggregated link

    Network

    All 3 hosts and NAS are connected with a Netgear dedicated 10 GB switch (low-end model).

    Using a standard vswitch

    Problem

    1 ESXi host has a computer virtual stored on storage on NAS Supermicro 1 pool. When a storage vmotion is running on a virtual machine that has a 60 GB VMDK, it takes a long time to complete. He started at 09:36, and is now 61% fine at 10:58.

    2. the network of 10 GB is where the vmotion traffic is allowed.

    3. If I use a link to 10 GB or a 1 GB link, I get the same speed.

    4. I have disabled all VM at a time given for the trial and who has not helped either.

    5. I tried a QNAP so storage vmotion, and I get the same speed.

    I use connection CAT6A cables. I have fine tuned for storage, and it seems to work better now. Seems to be linked to "writing - sync" as ESXi.

  • Senza thanks storage VMotion

    Hello to all

    Premetto che he mio e uno scrupolo più una domanda che in quanto credo, unfortunately, gia di know the risposta :-D

    veniamo al therefore: sto valutando the della functional di senza thanks introdotta nella versione 5.1 storage vmotion use;

    He problema e che i 2 cluster hanno a level di VCA different (stessa Intel architecture), quindi mi viene da Winegardner che he processo di validazione fallirebbe, my non ho trovato nessun esplicito re questa limitazione nella doc ufficiale di questa characteristic specifica.

    The mia speranza, ops domanda e secondo voi e possibile quindi?

    Saluti

    Ciao,.

    is non ho capito male, 2 cluster hai con lo stesso tipo di CPU Intel, pero con configurati 2 livelli VCA different. Perch is the sound CPU all equal?

    The VM you want migrare che da a cluster all'altro, risiede su uno No thanks dai storage 2.

    Ad ogni modo migrazione non Può avvenire has accesa VM, che lo storage sia thanks o meno, in quanto nel passaggio VM TR troverebbe ad andare a run known una che could avere delle istruzioni o diverse functional CPU. Abilitando the VCA in ogni caso, vai a mascherare o "castrare" in queste functional.

    The Unico modo che hai by migrare VM e da spenta.

    Is there any difference between el plugin developed por Andrew Kutz ( http://vip-svmotion.wiki.sourceforge.net/ ) para VI3 Stora VMotion y viene con vSphere integrated en vClient?

    Is there alguna limitacion para Storage VMotion? Me refiero a for example if los discos office deben ser independienteso no, UN cierto tamano maximo, con/sin instant aplicadas, clubs FC, iSCSI, NFS, etc...

    Hola Xacolabril,

    The difference between el plugin en VI3 Kutz y vSphere, are el Kutz plugin no estaba soportada, aunque worked perfectly.

    In vSphere the option of Storage VMotion to ha Morel bastante, ago that con Migración durante una Storage VMotion you can change el tipo virtual nightclub in the VM, a y thin to thick viceversa (inflate) aunque have than hacerlo con MV apagada.

    In summary, el plugin Kutz era muy util en version VI3, porque no Alicia than use el svmotion.pl desde el comand line pero en vSphere are no tiene sentido.

    Storage VMotion usa NFC (network file Copier) lo cual permite mover desde o iSCSI FC, a NFS datastore UN discos y viceversa. Inicialmente Storage VMotion solo soportaba mover los discos desde CF a CF.

  • Storage vMotion with Syncrep on Equallogic San

    Hello

    We recently bought 2 San Equallogic (PS6510ES) and turned on synchronous replication between them.

    We use ESXi 5.5 and followed the best practices guide to disable TCP ack and 60 logintimeout value.

    Everything seems to work fine until we tried Storage vMotion/migration and cloning VMS on the San.

    When we did the migration of 2 volumes on the EQL SAN storage (the target volume has active syncrep), the target volume will be out-of-sync and then the storage vMotion will hang sometimes.

    The worst is when such a problem has occurred, all other volumes on the EQL constantly to respond also. All volumes will not respond until we rebooted the corresponding ESXi host (NOTE: simple shut down/power outside the host won't help.) The San EQL will only return to normal after a reboot of the ESXi host).

    If we pause / off the syncrep before Storage vMotion, the problem will not happen.

    Is this normal or not?

    In addition, whenever the problem occurred, the latency of writing the corresponding volume will be dry and we will receive alerts similar to the following:

    connection iSCSI target ' xx.xx.xx.xx:3260, iqn.2001 - 05.com.equallogic:xxxxx - test-volume ' initiator 'xx.xx.xx.xx:xxxxx, eqlinitiatorsyncrep' failed for the following reason:

    Initiator, disconnected from the target when connecting.

    Thanks in advance.

  • question of vMotion and storage vMotion

    I have everything set, UCS 5108, ESXi host, VMs, I don't have a SAN connection yet... My question is if I can enable vMotion? Let's say I have a cluster in vCenter, within this group, I have attached two ESXi host, win2008 VM in an ESXi and running, I can migrate (using vMotion) as win2008 VM to an another ESXi without connection SAN?

    How storage vMotion to an ESXi host hardrive to an another ESXi host hardrive? Is this possible?

    Note: I have not connection SAN in this configuration

    One of the requirements for vMotion is shared storage that would allow visibility between source and destination ESXi hosts. (SAN, iSCSI or NFS).

  • VM VCS-E drop off air after storage vMotion

    We had a VCS-E, which dealt with a few calls.  VMware has performed a task of vMotion of storage on the server and the VCS-E completely dropped out of the air.

    Cisco has said that vMotion is taken in charge even if you may lose packets (although he said nothing about storage vMotion).  However, this time fallen completely out of the air box until I restarted the VCS-E interface vSphere, after what he came back fine.

    Versions of the software:

    ESXi 6, VCS X8.6

    Any ideas?

    8.6 do not officially support deployed on ESXi 6.0.

    Official support is not added for ESXi 6.0 up to 8.7 - looks too that there is a known issue with ESXi 6.0 which is exceeded in the Notes on the network connectivity that can align with this situation.

  • Question of Storage vMotion

    Hi all

    Newbie VMware admin here, I hope it's an easy question. I have several boxes of Microsoft SQL I need to move the drive on which the operating system is installed on, they have all RDM attached when I try a storage vmotion, it looks like her wanting to move all the drives instead of one, i have never attempted to move a system with RDM attached to it, but I need to get away from this former storage we have urged. All tips are appreciated thank you!

    Thank you

    You can migrate both at the same time, even if you choose a different destination.

  • Sequence of migration for storage vMotion?

    Hello

    I'm moving a couple of virtual machine data to another store.

    I noticed that different virtual machines get different status, such as:

    Copy of the files of virtual machines

    The active state of VM migration

    Resources currently used by other operations... Pending

    I know that it should migrate the active state of VM and then copy the files from the virtual machine.  However, for a machine virtual, it is already 67% current but status is always "the active state of the Virtual Machine migration."

    Is there that an article mentions the details of Storage vMotion?

    See you soon

    Resources currently used by other operations... Pending

    This is because for each host, we have 2 simultaneous storage vMotion migration limits, so if you raise more, system will be queued.

    about the documents, please see suite PDF, this technical white paper concerns the performance and best practices, but it has rather nice, explanations on memory storage Migration and VM migration.

  • Storage vMotion a VM except disk that is in another data store

    Hello

    I'm looking to convert a large number of virtual machines clones related to thick.  I decided the best way to do this is probably a simple a storage vMotion, but all the virtual machines have a secondary drive that is in another data store.  I have to make sure that disk #2 stays at its current location, while the machine virtual (Config and disk #1 files) are transferred to a new data store data store.

    I figured out how to move a virtual machine complete or a single disc but not a virtual machine under a disc.  I am able to make it through the advanced options of puissancela vSphere client so I guess it is techinically possible.

    Pointers or other ideas would be greatly appreciated.

    Kind regards

    Ty-

    You will need to use the API method, see for example Re: using several data stores, cannot migrate the vmx file in a data store

  • Storage vmotion esxi 5.5 to 6.0 does not not for some vm

    In a test cluster with 2 nodes with no storage storage shared (local only), host vmotion 5.5 to 6.0 host does not work.

    before the upgrade, I moved all the vm to a host.

    Then I upgraded to 6.0 host and tried to move all the VMS to the host 6.0 updated (moving host + storage).

    20 VM, 5 have been moved to the new host.

    Given that some machines were functioning and vmotion later in both directions from 6.0 to 5.5 works, I think that is no configuration error.

    Hello

    It seems that there could be a bug or that guests have difficulties to negotiate the transfer of drive on a network. VMotions storage are carried out via the management network (limitation of hard due to the codification)-are you sure that management networks are not overloaded or that they operate at the desired speed? This also happens with machines that have actually disabled followed block? It seems that this could be a problem.

    In addition, you use the 'old' client or Web client? It is possible that some features in vSphere 6.0 may have been omitted in the old thick client.

    Below are the errors:

    2015-04 - T 02, 03: 01:34.468Z | VMX | I120: MigrateShouldPrepareDestination: remote host does not support an explicit step to prepare migration destination.

    Thanks for the answers in advance and good luck!

  • Storage test 55 certification vmotion, storage vmotion fails with "Could not lock file" on the virtual machine during storage vmotion

    In my view, that it is a known problem in ESXi 5.5 Update 2 release notes, someone knows a solution yet? This is an excerpt from the release notes:

    • Attempts to perform live storage vMotion of virtual machines with RDM disks can fail
      Storage vMotion of virtual machines with RDM disks can fail and virtual machines can be considered in turned off of the State. Attempts to turn on the virtual machine fails with the following error:

      Cannot lock the file

      Workaround: No.

    VMware support for the record said that the patch will update 3, it is known as an intermittent problem. Finally, it happened to me on the 9th attempt.
