这个问题仅出现在storage vMotion时，迁移时弹出报错框——调用对象“VM-NAME” 的“VirtualMachine.Relocate”失败。

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.

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:

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:

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.
