Host Bus Adapter Requirements

The host bus adapter (HBA) in your server must match the library and drive's SCSI bus
type. If the interface to the library is HVD, the server must contain an HVD-compatible
HBA; if the interface to the library is LVD, the server must contain an LVD-compatible
HBA.

SCSI Device/Bus Type Issues

The following table lists the possible issues you could encounter if you mix interfaces on
the same bus.
