HP StoreEver ESL G3 Tape Libraries - Manual (Page 121)

The Save and Restore Library Configuration dialog box enables you to:
•
Save configuration settings of a library as a remotely or locally stored image.
•
Restore, revert, or rescue the library by applying a remotely or locally stored image of a library
configuration settings.
CAUTION: As a result of restore, rescue, or revert operations, the library shuts down. You must
have physical access to the library to bring the library back up. If you are performing a restore,
rescue, or revert operation using remote access, the library will remain shut down until the library
is directly powered back on.
Types of configuration image files
There are three types of configuration images that correspond to the Restore, Rescue, and Revert
commands:
•
The restore image is stored on a remote file system and is created any time you use the Save
command. You might restore the library configuration, for example, if the locally saved library
configuration is lost because the compact flash memory on the Management Control Blade
(MCB) is replaced. Because of the image remote location, the Save and Restore commands
are available only through the remote client.
•
The rescue image is stored locally on the library file system and is created any time you use
the Save Rescue command. You might rescue the library configuration, for example, if the
library becomes unstable due to a configuration change and you want to roll back the library
configuration settings to a previous state. The Save Rescue and Rescue commands are available
from both the remote client and the library OCP. You also have the option to save the rescue
image when you save the remote restore image.
•
The revert image is automatically created and stored locally as the first step of any restore or
rescue operation. The Revert command is available from both the remote client and the local
OCP.
When to save the library configuration
Even though you can choose to save the library configuration at any time, the library prompts you
to save in certain situations. Specifically, the library prompts you to save whenever you change
configuration settings in the following areas:
•
User accounts
•
Event notifications
•
E-mail setup
Other configuration changes that the library detects cause the library to generate warning events
for the Control subsystem. This causes a warning icon to appear on the Control system status button.
Be aware that if a more serious unresolved event already exists in that status group, the warning
event is generated, but no notification is sent until the more serious problem event is resolved or
closed.
CAUTION: Changes to hardware, such as removing drives, do not prompt you to save, either
by means of messages or warning events. Therefore, it is important to save the configuration image
after a hardware configuration change.
Saving a remote restore image
Use the Save command to save a library configuration restore image on a remote file system. To
make sure that the image captures all library configuration changes, save the image often.
