text: Alternatively, import and migration of external MDisks to another pool can be done by 
  selecting**Pools**→**System Migration**to start system migration wizard. For more information, 
  see Chapter 9, “Storage migration” on page 385. 
  
  **Include**
  The system can exclude an MDisk that has multiple I/O failures or has persistent connection 
  errors from its storage pool. Exclusion ensures that these errors do not interfere with data 
  access. If an MDisk has been automatically excluded, run the fix procedures to resolve any 
  connection and I/O failure errors. 
  
  If no error event is associated with the MDisk in the log and the external problem has been 
  fixed, select**Include**to add the excluded MDisk back into the storage pool. 
  
  The CLI command**includemdisk**performs same task. It needs the MDisk name or ID to be 
  provided as a parameter. See Example 6-28.
