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.
