Ensure that the SCSI cable is of high quality and conforms to Ultra 2 SCSI 

specifications. A lesser quality cable or a cable that does not conform to 

the Ultra 2 SCSI specification may cause intermittent write/read errors, 

SCSI timeouts, and corrupted data.

If the computer has booted up and operated properly prior to adding a 

SCSI HBA and tape drive, but does not boot now:

Remove the SCSI HBA controller if it is installed.

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.

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 

 LED to make sure the tape drive is receiving power.
