text: **7.8.9 Volume delete protection**
  
  To prevent active volumes or host mappings from being deleted inadvertently, the system 
  supports a global setting that prevents these objects from being deleted if the system detects 
  recent I/O activity to these objects. 
  
  Use the**chsystem**command to set the time interval for which the volume must be idle before it 
  can be deleted from the system. This setting affects the following commands: 
  
  (cid:2) rmvdisk 
  (cid:2) rmvolume 
  (cid:2) rmvdiskcopy 
  (cid:2) rmvdiskhostmap 
  (cid:2) rmmdiskgrp 
  (cid:2) rmhostiogrp 
  (cid:2) rmhost 
  (cid:2) rmhostport 
  
  These commands fail unless the volume was idle for the specified interval or the**-force**
  parameter was used. 
  
  To enable volume protection by setting the required inactivity interval, issue the following 
  command: 
  
  svctask chsystem -vdiskprotectionenabled yes -vdiskprotectiontime 60 
  
  The**-vdiskprotectionenabled yes**parameter enables volume protection and the 
  **-vdiskprotectiontime**parameter specifies for how long a volume must be inactive (in 
  minutes) before it can be deleted. In this example, volumes can only be deleted if they were 
  inactive for over 60 minutes.
