  • 1.  Physically moving storage from one Rack to Another

    Posted Feb 27, 2015 01:09 PM

    Dear team,

    We are planning to move our storage from one Rack to another.

    it's a small storage total usable capacity is 3TB (EMC CX4-120). created one LUN size of 3TB and mapped the same to 14 ESXi host.

    That LUN is selected as heartbeat datastore.  we will follow below POA to perform said activity.

    -> Select Home => datastore & datastore clusters => Select datastore => Virtual machine => take VMs export

    => gracefully shutdown all VMs which are hosted on this datastore (non production vms no need to migrate the same on other datastore)

    => select different datastore for datastore heart beat (Need ur help how to do that)

    => remove this datastore from datastore heartbeat (Need ur help how to do that)

    => Unregister all VMs  (Please confirm do i need to unregister VMs ???)

    => unmount and detach then unmap the datastore from Storage end (if i remap the same on all esxi host will i able to see the data onit, I don;t want to loose data)

    => gracefully shutdown the SAN storage

    => Disconnect cables from storage.

    => Move the storage from rack1 to rack2

    => Connect cables and poweron the storage

    => attach and mount the datastore on all esxi host

    or   if i unmap the datastore before activity then map the same datastore on all 14 esxi host and rescan the HBA

    => mount the datastore on all esxi host and it will be visible on all esxi host

    => register all vms

    => Poweron & check all network connection.

    => Handover to application team.

    point which are marked as bold need asisstance on the same , also add missing steps if any.

    regards

    Mr VMware

    Please find the right steps

    above POA is 100% okay and tested.

    before activity take VM export which are stored on datastore


    Home => datastore and datastore cluster => select the datastore => VMs => add all the columns => take VM export


    take latest RVTool export.



    shutdown all VMs => Unregister all VMs and Templates => RK on Cluster (edit setting  => datastore hearbeating => here we have to select another datastore and click on OK)


    to confirm new datastore is visible as datastore heartbeat select Cluster=> Sumamry => Custer Status => Heartbeat Datastore )

    if we are able to see new datastore then now remove old datastore from datastore heartbeat


    RK on Cluster (edit setting  => datastore hearbeating => here we have to uncheck datastore and click on OK)


    unmount => detach(need to perform this step on all esxi host) => san team will unmap => start storage movement activity (poweroff storage) => move the storage => poweron => san team will map the datastore =>attach((need to perform this step on all esxi host) => mount the datastore


    Register all VMs


    Poweron All VMs if get message (moved it or copied it ) select Moved it.


    if above steps followed then it won't throw any error, will work seemlessly.


    Yes we need to unregister all VMs and Templates before unmount a datastore.
