Viewing the configuration
You can select View Configuration from the Main Menu to display the number of
each logical drive, and to display the size, RAID level, state, stripe-unit size, write
policy, read-ahead status, and creation date for each logical drive.
Using the advanced configuration functions
You can select the Advanced Functions to restore the controller configuration to
factory default settings, copy the configuration to the controller from the connected
physical drives, configure BIOS settings, and view the controller and PCI
information.
When you select the Advanced Functions from the Main Menu, the following
choices are displayed.
Attention: Be careful when making selections from this menu. If you change the
configuration, you might lose data.
v
Restore to Factory Default Settings is used to reset the configuration. When
you reset the configuration, you will not have access to any data stored on the
logical drives attached to the selected ServeRAID controller.
This choice deletes the existing configuration information, sets all functional
physical drives attached to the controller to the ready state, and deletes all
logical drives defined for the controller.
This choice does not change any of the ServeRAID controller settings (such as
the stripe-unit size, rebuild rate, and so on) from their current values.
