Initializing, Viewing, or Synchronizing the ServeRAID II Controller Configuration

The ServeRAID configuration information stored in nonvolatile random-access memory (NVRAM) is critical to the reliable operation of the disk array. To protect the integrity of the configuration information, the configuration information is also stored in an EEPROM and on each RBL and ONL hard disk drive. Each time you change the configuration information, all corresponding copies are updated automatically.

During POST, if the NVRAM configuration information does not match the configuration information stored in the EEPROM or on the hard disk drives, an error message appears.

You can use the Init/View/Synchronize Config menu to initialize, view, or synchronize the ServeRAID controller configuration information.

To initialize, view, or synchronize the configuration information:

Start the ServeRAID Configuration program (see 'Starting the ServeRAID Configuration Program').
Select Advanced Functions from the Main Menu, then, press Enter.
Select Init/View/Synchronize Config from the next menu, then, press Enter.
A screen similar to the following appears.

Descriptions of the choices available from this menu are as follows:
- Help provides information about the choices available on the menu. You also can press F1 from any csreen to obtain online Help.
- Initialize Configuration lets you set the configuration of the ServeRAID controller to its default settings. This choice sets the states for all powered-on hard disk drives to RDY, all CD-ROM drives to CDR, and all tape drives to TAP. This choice also deletes all previously defined arrays and logical drives. This choice writes a 'Null Configuration' for the ServeRAID controller.
  You must select this choice if a message appears stating that you have an unrecoverable configuration error, because valid configuration information does not exist.
- View NVRAM Configuration displays the current configuration settings stored in the controller's NVRAM.
- View EEPROM Configuration displays the current configuration settings stored in the the controller's EEPROM.
- View Hard Drive Configuration displays the configuration settings for the selected ONL or RBL hard disk drive. To view the stripe order, press Enter.
- View Change List displays the device state configuration changes that the ServeRAID controller reported since you restarted or turned on the server.
  - View Power-on Change List displays the hard disk drive device state changes since the last time that you restarted or turned on the server.
  - View Wrong SCSI ID List provides a list of hard disk drives that were found at a different SCSI ID location (bay) when you restarted or turned on the server.
  - View Unidentified Drive List provides a list of hard disk drives that have identifiers that do not match the stored configuration information.
    The identifier consists of both the configuration host ID and a time stamp. You can define the host ID (for example, a host ID can be the serial number of the server) as any string up to 12 characters. (See 'Viewing or Changing the ServeRAID Controller Parameters' for more information.)
- Configuration Synchronization. See 'Configuration Synchronization' for a description of this choice.
Use the Up Arrow ( ) or Down Arrow ( ) key to highlight the choice from the menu, then, press Enter.
Follow the instructions that appear on the screen.
