VMware Storage VMotion Fails on Virtual Disks Configured as Independent-Persistent
Details
VMware Storage VMotion currently fails to support the migration of virtual machine disks that are configured as independent disks. When Storage VMotion fails, vmdk files similar to the following might be visible on the source datastore: DMotion-scsi0:02_RHEL4SVM_TEST1_2-delta.vmdk
Solution
This is a known issue. As a work around, temporarily change the disk type to persistent, and migrate the virtual machine disks.
