Checking the SCSI connection
Use the following questions to help you check your SCSI connection. Many users can use HP Library & Tape Tools to check the SCSI bus type, see page 37. If you answer ‘Yes’ to all these questions, you are ready to install your autoloader. If you answer ‘No’, you will probably need to purchase and install additional items. For compatibility and product details, go to

2Is the SCSI bus type correct for the SCSI specification of the device?
Yes
3Will the autoloader be the only device on the bus? This is the recommended configuration. Do not connect to a RAID controller or the same SCSI bus as your disk drive.
Yes
No
No
No
Purchase and install one of the recommended HBAs into an unused
See table below. If the SCSI bus differs from the recommended specification for the drive, performance of either the drive or the bus may be impaired. Consider replacing your card with one of the recommended HBAs.
If you have an Ultra HBA, performance may be impaired. Consider installing (if you have a spare PCI slot) or replacing your card with an Ultra2, Ultra3 (160) or Ultra4 (320) HBA. Make sure the last device on the bus is terminated.

SCSI Bus Type | Supported |
Ultra wide LVD | Yes. This is a recommended configuration as long as the drive is |
| the only device on the SCSI bus. |
|
|
Ultra 2 LVD, Ultra 3 (160) LVD, | Yes. These are recommended configurations, particularly if there |
Ultra 4 (320) LVD | are several devices on the SCSI bus. |
|
|
Ultra wide, | Yes. But this is not a recommended configuration as it will restrict |
| performance. |
|
|
Ultra narrow, | Yes. But this is not recommended as it will severely restrict |
| performance and you will need a suitable cable or adapter. |
|
|
High Voltage Differential | No. The drive will not work and you may damage the drive or |
| controller |
