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.

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.

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.


Performing a Low-Level Disk Format: You can use the Format Disk feature of the SCSISelect Utility to perform a low-level format on a hard disk drive.

Depending on the hard disk drive capacity, the low-level format program could take up to two hours.

When To Use the Low-Level Format Program: Use the Low-Level Format program:

Note: For information about backing up all of the files, see the operating-system documentation.

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.

  1.  If the hard disk is working, make a backup copy of all the files and programs on the hard disk drive
  2.  Select Format Disk, then, follow the instructions on the screen.

    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.

  3.  To install an operating system after the hard disk drive is formatted, follow the instructions in the  'Software and Netfinity Manager Reference' section of this Server Library.

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.
