text: **Modify Threshold**
  The storage pool threshold refers to the percentage of storage capacity that must be in use 
  for a warning event to be generated. When you use thin-provisioned volumes that 
  auto-expand (automatically use available extents from the pool), monitor the capacity usage 
  and get warnings before the pool runs out of free extents, so that you can add storage. 
  
  **Note:**The warning is generated only the first time that the threshold is exceeded by the 
  used-disk capacity in the storage pool. 
  
  To modify the threshold, select**Modify Threshold**and enter the new value. The default 
  threshold is 80%. To disable warnings set the threshold to 0%. 
  
  The threshold is visible in the pool properties and is indicated with a red bar as shown in 
  Figure 6-11.
