Computer will not
Boot

If the computer has booted up and operated properly prior to adding a
SCSI HBA and tape drive, but does not boot now:
1 Remove the SCSI HBA controller if it is installed.
2 Reboot the system.
• If the system boots normally, the problem is resolved.
• Otherwise, ensure that SCSI HBA is compatible with system,
does not have burnt components. Reseat the SCSI HBA in a
different PCI slot and reboot the computer. If the system still
does not boot, contact Customer Support.

1 Reboot the system and check whether the SCSI controller is seen at
boot up. You should see messages similar to:

• If the SCSI Controller is not recognized during system boot,
contact Customer Support.
• If the SCSI controller is recognized during system boot.,
determine whether the tape drive is recognized when the SCSI
controller scans for devices. You should see messages similar to:
“SCSI ID 6 CERTANCE ULTRIUM 3 160
