You can continue to create more logical drives or exit by clicking CLOSE .
In most storage system environments, creating the logical drives,
assigning them their logical unit numbers (LUNs), and setting the
availability is sufficient to meet the requirements for setup. For more
advanced and complex systems using storage area networks, you may
want to perform the more advanced SAN LUN mapping. See
“SAN LUN
Mapping” on page 61. Otherwise access your operating system to make
the new drives available for use.
Saving the configuration
When you create arrays, create logical drives, establish hot spare drives, define
SAN LUN mappings, and change the parameters of specific controller settings,
a file containing this information (known as the
configuration ) is written to all
the disk drives that are members of the array. StorView can capture that file so
you can save it to an external file. This file can be important if a configuration
should become corrupt or damaged. You can use the file to reload the settings
and re-establish your storage system. Otherwise, you would be required to rely
on your memory or notes that you may have taken when you set up the system,
which may not be complete.
Caution
If you cannot restore the configuration
exactly as it was, you cannot restore
access to the data and it is lost.
Because of day-to-day changes to your system, which cause differences
between the configuration file and the actual configuration, you should
periodically update the configuration using the
Save function. An example of
a change would be a drive failure. A hot spare drive automatically replaces the
failed drive and the data is rebuilt on the new drive with new parity. That
indicates a significant change in the configuration because the failed drive
member has been removed, a new drive has taken its place, and the hot spare
is now an array member. Restoring a configuration with a missing drive causes
the existing data to be lost. Therefore, when configuration changes occur, you
should save the configuration again with a new file name.
To save the configuration:

From the Main window’s Configuration tool bar click Archive
Configuration . The Configuration Archival Operations window opens.
