• VMware Storage VMotion fails to migrate virtual machine disks that are configured as independent disks.
• .vmdk files similar to this are on the source datastore:
  
  DMotion-scsi0:02_RHEL4SVM_TEST1_2-delta.vmdk

This is a known issue. As a work around, temporarily change the disk type to persistent and migrate the virtual machine disks.

To change a disk to persistent:

1. Power off the virtual machine.
2. Click Edit Virtual Machine Settings.
3. Select the Hard Disk.
4. Uncheck the Independent Mode field.
5. Click OK.
   

1. Persistent hardisk without selecting either of the two independent modes:
   
   scsi0:0.present = "true"
   scsi0:0.fileName = "ind.vmdk"
   scsi0:0.deviceType = "scsi-hardDisk"
   
2. Independent-Persistent mode:
   
   scsi0:0.present = "true"
   scsi0:0.fileName = "ind.vmdk"
   scsi0:0.mode = "independent-persistent"
   scsi0:0.deviceType = "scsi-hardDisk"
   
3. Independent-Nonpersistent mode:
   
   scsi0:0.present = "true"
   scsi0:0.fileName = "ind.vmdk"
   scsi0:0.mode = "independent-nonpersistent"
   scsi0:0.deviceType = "scsi-hardDisk"
   
4. Normal-Persistent mode:
   
   scsi0:0.present = "true"
   scsi0:0.fileName = "ind.vmdk"
   scsi0:0.deviceType = "scsi-hardDisk"
   scsi0:0.mode = "persistent"
