Figure 6-31   Upgrading a drive or a set of drives
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.
