Control Blade (MCB) is replaced. Because of the image's remote
location, the Save and Restore commands are available only through
the remote client.
• The rescue image is stored locally on the library's file system and is
created any time you use the Save Rescue command. You might
rescue the library's configuration, for example, if the library becomes
unstable due to a configuration change and you want to roll back the
library's configuration settings to a previous state. The Save Rescue
and Rescue commands are available from both the remote client and
the library's touch screen. 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 touch screen.
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
• RAS event notifications
• E-mail setup
Other configuration changes that the library detects cause the library to
generate warning tickets 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 ticket already exists in that status group, the warning
ticket is generated, but no notification is sent until the more serious
problem ticket is resolved or closed.
CAUTION
Chapter 5 Maintaining Your Library
Changes to hardware, such as removing drives or
I/O blades, do not prompt you to save, either by
means of messages or warning tickets. Therefore,
it is important to save the configuration image
after a hardware configuration change.
