Using the SCSISelect Utility program
Note: If the server has a redundant array of independent disks (RAID) adapter installed, use the configuration method that comes 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.

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 program 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 for the SCSISelect messages as each drive spins up.
After the drive that you want to view or format spins up, press Ctrl+A.
When to use the low-level format program: Use the Low-Level Format program:
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, have the system serviced.
