PC Server 704 - Changing the ServeRAID Adapter Parameters

Applicable to: World-Wide

Changing the ServeRAID Adapter Parameters

Display/Change Adapter Parameters allows you to view and change the adapter's configuration parameters.

To display or change the adapter parameters:
1. Start the ServeRAID configuration program (see 'Starting the ServeRAID Configuration Program—).
2. Select Advanced Functions from the Main Menu.
3. Select Display/Change Adapter Params and press Enter.

Display/Adapter Status allows you to view the status of the adapter.

Change Adapter Host/SCSI ID allows you to change the adapter SCSI ID and the SCSI transfer rate. You can also define the host configuration ID as any 12 characters. In addition, you can change the number of drives in a group that will startup simultaneously, and set the start-up delay in seconds between groups of drives.

Set BIOS Compatibility Mapping allows you to set the BIOS mapping to 2 GB or 8 GB.

Set Channel => Bank Mapping allows you to specify which bank is connected to each of the internal Channels
on the RAID adapter.

The following table shows the default mapping.

Bank	Default Connection
C	Channel3
D	Channel2
E	Channel1

You can also specify the setting of the SCSI ID backplane jumper. This mapping is critical for the correct operation of the Administration and Monitoring program, which uses the settings to identify drives, control power to specific drives, and operate the SCSI LEDs.

For example, suppose you daisy-chained banks D and E, connecting the input connector on bank D to Channel 2 on the adapter. The SCSI ID backplane jumper on bank E is set to HI. Refer to the backplane information in the PC Server Hardware Maintenance Manual for the system you are servicing. In this configuration, Channel 1 is available for external devices. Set the Bank Mapping as shown:

Channel	Low ID	High ID
Channel 1	External devices	External devices
Channel 2	D	E
Channel 3	C

4. Follow the instructions on the screen.
