  For an external MDisk, the system cannot calculate its exact performance capabilities, so it 
  has several predefined levels. In rare cases, statistics analysis might show that Easy Tier is 
  overusing or under-using an MDisk. If so, levels can be adjusted only by using the CLI. Use 
  **chmdisk**with**-easytierload**parameter. To reset Easy Tier load to system-default for chosen 
  MDisk, use**-easytier default**, as shown in Example 10-2. 
  
  Example 10-2 Changing Easy Tier load

  IBM_Storwize:ITSOV7K:superuser>lsmdisk mdisk2 | grep tier
