備份VM後VPX_DISABLED_METHODS未刪除，導致vMotion失敗

 這個問題僅出現在storage vMotion時，遷移是彈出報錯框——Call “VirtualMachine.Relocate” for object “VM-NAME” on vCenter Server “vCenter-Name” failed。

找到VMWare KB，說明vStorage API備份後VPX_DISABLED_METHODS未刪除，經檢查確實存在問題的VM有NB_LAST_BACKUP標誌。再按照KB裏所述SQL，找到VPX_DISABLED_METHODS相關行，刪除後問題解決。

1. Stop the vCenter Services.
2. Take a backup of the vCenter Server database.
3. Run this command against the vCenter Server database.

   1	select * from VPX_VM WHERE FILE_NAME LIKE '%Virtual-Machine-Name%'

4. Take note of the numerical ID value returned by the above SQL stmt, as this will be required in the SQL stmt in steps 5 and 6.
5. Run this command against the vCenter Server database, to confirm the stale entry:

   1	select * from VPX_DISABLED_METHODS WHERE ENTITY_MO_ID_VAL = 'vm-<ID from step 4>'

6. To remove the stale entry run this command against the vCenter Server database:

   1	delete from VPX_DISABLED_METHODS WHERE ENTITY_MO_ID_VAL = 'vm-<ID from step 4>'

7. Start vCenter Server Services, then retry the Storage vMotion.
