text: To analyze all the volumes that are on the system, run the CLI**analyzevdiskbysystem**
  command. 
  
  The use of the command analyzes all the current volumes that are created on the system. 
  Volumes that are created during or after the analysis are not included and can be analyzed 
  individually. Progress for analyzing of all the volumes on system depends on the number of 
  volumes that are being analyzed and results can be expected at about a minute per volume. 
  For example, if a system has 50 volumes, compression savings analysis takes approximately 
  50 minutes. 
  
  You can run analysis on a single volume by specifying its name or ID as a parameter for the 
  **analyzevdisk**CLI command. 
  
  To check the progress of the analysis run the**lsvdiskanalysisprogress**command. This 
  command displays the total number of volumes on the system, total number of volumes that 
  are remaining to be analyzed, and estimated time of completion. 
  
  The command**lsvdiskanalysis**is used to display information for thin provisioning and 
  compression estimation analysis report for all volumes. 
  
  You can also use the GUI to run analysis. Navigate to the**Volumes**pane, right-click any 
  volume, and select**Space Savings**→**Estimate Compression Savings**, as shown in 
  Figure 10-18.
