备份VM后VPX_DISABLED_METHODS未删除，导致vMotion失败

 这个问题仅出现在storage vMotion时，迁移是弹出报错框——Call “VirtualMachine.Relocate” for object “VM-NAME” on vCenter Server “vCenter-Name” failed。

找到VMWare KB，说明vStorage API备份后VPX_DISABLED_METHODS未删除，经检查确实存在问题的VM有NB_LAST_BACKUP标志。再按照KB里所述SQL，找到VPX_DISABLED_METHODS相关行，删除后问题解决。

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.
