  For information about updating drive firmware, see Chapter 13, “RAS, monitoring, and 
  troubleshooting” on page 673. 
  
  **Action: Show dependent volumes**
  Select**Show Dependent Volumes**to list the volumes that are dependent on the selected 
  drive. A volume is dependent on a drive or a set of drives when removal or failure of that drive 
  or set of drives causes the volume to become unavailable. Use this option before you do 
  maintenance operations, to confirm which volumes will be affected. 
  
  Figure 6-32 shows the list of volumes dependent on a set of three drives that belong to the 
  same MDisk. This configuration means that all listed volumes will go offline if all selected 
  drives go offline. If only one drive goes offline, there is no volume dependency.
