PCServer330 - Resetting the Adapter Configuration

Applicable to: World-Wide

Resetting the Adapter Configuration:
The RAID configuration information stored in the adapter NVRAM is critical to reliable operation of the disk-array. Therefore, to protect the integrity of the configuration information, copies of the configuration information are stored in the adapter EEPROM and on each hard disk drive in a Rebuild or On-line state that is defined in the adapter NVRAM configuration. Each time the configuration information is changed, all corresponding copies are updated.

During POST, if the configuration information in the adapter NVRAM, EEPROM, and hard disk drive does not match, an error message appears. You can view each configuration to determine which you want to use.

The Init/View/Synchronize Configuration menu enables you to view or reset the following parameters:
- Initialize Configuration restores the factory default settings, and resets all functional, connected, hard disk drives to the Ready
(RDY) state.
- View NVRAM Configuration displays the current configuration settings for the adapter's NVRAM.
- View EEPROM Configuration displays the current configuration settings for the adapter's EEPROM.
- View Hard Drive Configuration displays the current configuration settings for the selected hard disk drive that is in the on-line (ONL) or rebuild (RBL) state.
- View Change List displays the configuration conflicts that the ServeRAID adapter reported since the last time the server was
powered on or restarted. For more information, see 'Viewing Configuration Changes—.

To initialize, reset, or view the adapter configuration:
1. Start the ServeRAID configuration program (see 'Starting the ServeRAID Configuration Program—).
2. Select Advanced Functions from the Main Menu.
3. Select Init/View/Synchronize Config.
4. Select your choice from the next menu; then press Enter.

5. Follow the instructions on the screen.

Viewing Configuration Changes:
This option allows you to view the configuration changes that might have occurred since the last time the server was powered on or restarted.

- View Power-on Change List displays any drives that have changed states since the last time the server was powered on or restarted.
- View Wrong SCSI ID List provides a list of hard disk drives that were found at a different SCSI ID location than the last time the server was powered on or restarted.
- View Unidentified Drive List provides a list of hard disk drives that have an identifier that does 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 as the server serial number or any string, up to 12 characters. (See 'Changing the ServeRAID Adapter Parameters— for more information.)

Synchronizing the Adapter Configuration:
When the configuration information in the adapter NVRAM, EEPROM, and hard disk drives does not match, you can select one source, and copy the selected configuration information to the other locations. This menu provides options to synchronize this configuration information.

- EEPROM as Source copies configuration information from the adapter EEPROM to NVRAM and to all hard disk drives in a Rebuild or On-line state that are defined in the adapter EEPROM configuration.
- NVRAM as Source copies the configuration information from NVRAM to the adapter EEPROM and to all hard disk drives in a Rebuild or On-line state defined in the NVRAM configuration.
- NVRAM and POCL as Source updates information from the power-on change list with the information in NVRAM. This information is then copied to the adapter EEPROM and to all hard disk drives in a Rebuild or On-line state that are defined in the NVRAM configuration.
- Hard Disk Drives as Source retrieves configuration information from hard disk drives. The configuration information is then copied to the adapter NVRAM and EEPROM.
- Identified HDD as Source updates the configuration information with stored configuration information on a hard disk drive that matches the identifiers stored in the NVRAM. The updated configuration information is then copied to NVRAM, the adapter
- EEPROM, and the hard disk drives configured in an array. Specific HDD as Source retrieves the configuration information with stored configuration information on the hard disk drive that you select. The updated configuration information is then copied to NVRAM, EEPROM, and configured hard disk drives.
