Prohibiting Changes to Read/Write Even When the Retention
Term is Over (Enabling/Disabling the Expiration Lock Function)
If you follow the procedure below, none of the Read Only volumes and Protect volumes can be
changed to Read/Write volumes, even after the retention term ends.
To prohibit attempts to change the access attribute to Read/Write even when the retention term is
over:
1.
Ensure that you are in Modify mode.
For detailed information, see the HP StorageWorks XP24000/XP20000 Remote Web Console
User Guide.
2.
In the Data Retention window (
on page 15), locate the button that is displayed to the
right of Expiration Lock.
• If the button is Disable -> Enable, go to the next step.
• If the button is Enable -> Disable, you do not need to follow the rest of this procedure because
attempts to change the access attribute to Read/Write are already prohibited.
3.
Select Disable -> Enable.
A message appears and asks if you want to apply the settings to the storage system.
4.
Click OK.
The button changes to Enable -> Disable, and then expiration lock is enabled. When expiration
lock is enabled, the access attributes of volumes cannot be changed to Read/Write even after
the retention term ends.
Notes:
•
If you disable expiration lock, the access attribute can be changed to Read/Write after the retention
term ends. To disable expiration lock, click Enable -> Disable to the right of Expiration Lock.
•
Sometimes nothing happens when you click Disable -> Enable or Enable -> Disable. To get out of
this situation, see “
Protecting Logical Volumes Against Storage System Copy
Operations (Setting the S-VOL Disable Function)
Assigning the Read Only or Protect attribute is one of the ways to prevent data in a volume from being
overwritten by storage system copy software. Volumes having the Read Only or Protect attribute are
protected against these copy operations, but are also protected against any other form of write
operations.
