Using the SCSISelect Utility
Note: If the server has a RAID adapter installed, use the configuration method supplied with the RAID adapter to view or change SCSI settings for attached devices.
The server comes with a menu-driven configuration utility, called SCSISelect, that allows you to view and change SCSI settings.
You can use the SCSISelect Utility to:
Starting the SCSISelect Utility: You can access this program when you start the server.
The SCSISelect prompt appears after the IBM logo appears.
Press Ctrl+A immediately after the SCSISelect prompt appears:
<<< Press <CTRL><A> for SCSISelectÓ Utility! >>>
Use the Up Arrow ( ) or Down Arrow ( ) key to move the highlight bar to the various menu choices.
Press Esc to return to the previous menu. Also, you can press the F5 key to switch between color and monochrome modes (if the monitor permits).
To change the settings of the displayed items, follow the directions on the screen. Then, press Enter.
SCSISelect Utility Choices: The following choices appear on the SCSISelect Utility menu:
Configure/View Host Adapter Settings: To view or change the SCSI controller settings, select Configure/View Host Adapter Settings and follow the directions on the screen.

This menu has the following choices:
The default SCSI ID of the SCSI controller is 7. Do not change this value.
The default value is Enabled. Do not change this value.
The default value is Automatic. Do not change this value.
Select this choice to configure startable device parameters. Before you can make updates, you must know the ID of the device whose parameters you want to configure.
Select this choice to configure SCSI device parameters. Before you can make updates, you must know the ID of the device whose parameters you want to configure.
Note: When the Maximum Sync Transfer Rate is set to 40.0, this value represents the transfer rate for
When the Maximum Sync Transfer Rate is set to 20.0, this value represents the transfer rate for Fast SCSI devices.
Select this choice to view or change the settings for advanced configuration options. These options include enabling support for large hard disk drives and support for drives with UltraSCSI speed.
SCSI Disk Utilities: To see the IDs that are assigned to each SCSI device or to format a SCSI device, select SCSI Disk Utilities from the SCSISelect Utility menu.
To use the utility, select a drive from the list. Read the screens carefully before making a selection.
Note: If the following screen appears, you might have pressed Ctrl+A before the selected drives were ready.
Restart the server and watch the SCSISelect messages as each drive spins up. After the drive that you want to view or format spins up, press Ctrl+A.
Starting the Low-Level Format Program
- Attention - The low-level format program erases all data and programs.
Note: If the server has a RAID adapter installed, refer to the RAID adapter documentation for instructions for performing a low-level format on a hard disk drive attached to the PCI RAID adapter.
Note: Hard disks normally contain more tracks than their stated capacity
(to allow for defective tracks).
A message appears on the screen if the defect limit is reached. If this happens, replace the drive.
Verify Disk Media: The verify disk media utility scans the drive for defective sectors. All recoverable information found on defective sectors is remapped to alternate sectors.
This utility also indicates if the drive is defective.
Use this utility if you suspect bad sectors on a disk drive.
