  • 1.  How to Unmap a datastore from esxi host without loosing data

    Posted Feb 27, 2015 02:05 PM

    Dear team,

    I want to unmap a datastore which is mapped on two cluster (cluster1 10 esxi host and cluster2  4 esxi hosts)



    Query1

    Which step will be correct

    unmount => detach => start storage movement activity (poweroff storage) => move the storage => poweron => attach => mount

    or

    unmount => detach => san team will unmap => start storage movement activity (poweroff storage) => move the storage => poweron => san team will map the datastore =>attach => mount

    Query2:

    once i browse i am able to see vpshere ha and dvs data folder, just want to confirm if i want to unmount and detach the datastore will it allow me to do that or it will throw an error, please confirm.

    Query3:

    if we unmount and detach a datastore, before that do i need to unregister all VMs??



    regards

    Mr Vmware

    Please find the right steps

    Query1


    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.


    Query2:

    it won't throw any error, will work seemlessly.


    Query3:

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