          1.check the list of VMs connected to the particular datastore

          2.check the VMs cd is connected with any ISO in the datastore

          3.IF yes change it to client device only.

          4. Try to unmount the Datastore

            Saravan,

             

            1.check the list of VMs connected to the particular datastore-----------          no vms

            2.check the VMs cd is connected with any ISO in the datastore-------    Not connected

            3.IF yes change it to client device only----- -----------------------------------     Not connected

            4. Try to unmount the Datastore

             

            Even checked the ScratchConfig its not pointing to old datastore it set to /temp.

             

            Anyother suggestions on the same ?

             

             

            Regards,

              can you make sure these checklist are satisfied

               

              • The datastore is not managed by Storage DRS.
              • The datastore is not part of a datastore cluster.
              • The datastore is not used for vSphere HA heartbeating.
              • Storage I/O control is disabled for this datastore.

               

              Can you try login into the esxi and run

               

              lsof | grep datastore_name

               

              there should be no files locked

               

              if you are still unable to unmount then there should be some process lock holds the datastore on esxi level.

               

              rebooot the esxi and try unmount once again

               

              after the reboot try again still if get the same error then there is no problem with the esxi

               

              we need to troubleshoot on the vcenter

               

              Disable the VSA plug-in from the vSphere Web Client  and try to unmount the datastoreonce unmounted then enable the plugin..

              if we face the same error after the plugin disable then try restart the appliance or the vcenter

              then try to unmount it again..!!

               

              lets give a try

               

              cheers!!!!
