the Ultra 2 SCSI specification may cause intermittent write/read errors,
SCSI timeouts, and corrupted data.
Troubleshooting Suggestions 7
Computer will not
Boot
7
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, then there is a problem with the
SCSI HBA.
• 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 Technical Support.
Computer Boots
but Does not
Recognize the
Tape Drive
7
If the computer boots but does not recognize the tape drive reboot the
system and check whether the SCSI controller is seen at boot up. You
should see messages similar to:
SCSI Adapter Manufacturer SCSI BOIS xxxxxxx
CHA: SCSI ID #, SCSI Device Name
SCSI ID #, SCSI Device Name”
• If the SCSI Controller is not recognized during system boot, contact
Technical 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:
Bus Target Lun Device
0 0 0 CERTANCE ULTRIUM 2
• If the tape drive is not recognized during the SCSI controller scan,
check the
Power LED to make sure the tape drive is receiving power.
